Definitions

  • This invention relates to a method of, and apparatus for, controlling the delivery of a medication and is particularly applicable to a patient controlled analgesic delivery apparatus, but is not restricted thereto. It could also be used for other patient controlled medication such as, for example, sedation/anaesthesia, blood pressure.
  • the pain felt by a patient if no analgesic is used, is normally in a curve with respect to time, where the maximum pain can occur in the early hours after the operation and, over a 24 hour period, the level drops substantially.
  • the object of the invention is to provide a new method of controlling the delivery of medications, specifically analgesia, to patients, and an apparatus to be used therewith to more closely match the time related pain wave of the patient with appropriately tailored bolus doses, variable lock at times and modified background infusion.
  • the invention in its broadest aspect includes a method of controlling the delivery of a medication to a patient to alleviate a condition, including a control device and a pump, the control device enabling the patient to select a pre-determined quantity of medication from one of a possible number of quantities, the selection, initiating the operation of the pump which controls the delivery of the said quantity of medication characterized in that the patient can, over a period, repeatedly operate the control device to maintain the medication at a variable and adaptive value, optimum to maintain control of the condition.
  • the quantity of medication selected by the patient may be monitored by carers and it is also preferred that the system is so arranged as to prevent the patient from exceeding a predetermined dosage in a specific period called the lockout period.
  • the invention also includes an apparatus to deliver medication to a patent including a pump and a control system which control system includes a control device which may be operated to deliver different quantities of medication and a control means which receives the signals received from the control device and effects operation of the pump, the control means being able to monitor the operation of the control means and the pump to provide an indication to carers as to the times of operation of the control device and the pump and the quantity of medication passed to the patient.
  • control system includes a control device which may be operated to deliver different quantities of medication and a control means which receives the signals received from the control device and effects operation of the pump, the control means being able to monitor the operation of the control means and the pump to provide an indication to carers as to the times of operation of the control device and the pump and the quantity of medication passed to the patient.
  • the invention also relates to a control means for use with an apparatus to deliver medication which includes a handset having a number of positions each of which corresponds to the degree of pain as seen by the patient.
  • the handset also includes a confirmation device to commence the operation of a pump associated with the handset.
  • Each position on the handset may be associated with a tone of a particular pitch to give an audible indication of the position selected.
  • the control means may also have provision to prevent the operation of the control device to deliver more than a pre-determined quantity of medication over a particular period and to provide to the carer an indication that there had been request(s) for delivery of medication which had not been satisfied.
  • the quantity of medication provided by any particular position of the handset may be modified in respect of time so that, as time passes, the quantity of medication will be such as to provide an apparently equal effect taking into account the position it is expected that the patient will be along the pain curve.
  • Figure 1 shows a pain curve where a patient is using a conventional patent controlled analgesic apparatus
  • Figure 2 shows a similar pain curve for a patient using the apparatus of the invention
  • Figure 3 shows one form of patient operated control device for the apparatus; and Figure 4 shows a schematic flow chart of the components of the system of the invention, and their interaction.
  • Figure 1 and 2 have as their envelope a typical pain curve 10 which is plotted as pain intensity against time.
  • the curve of a particular patient can depart substantially from this idealised curve, but will be of the same general shape.
  • this bolus is usually controlled to set the quantities of the bolus to be low so as to be safe with more sensitive patients.
  • the bolus selected may leave a substantial pain gap, represented by the height of the curve envelope above the effect of the bolus.
  • the system of the invention uses a system whereby the patient can operate the introduction of analgesic based on pain level as experienced by the patient.
  • analgesic based on pain level as experienced by the patient.
  • the apparatus has a handset 20 which can have, in the particular example, some ten positions 21 which are graded from that for mild pain to severe pain.
  • Each position can be provided with an indicator light 22 and when a particular value is pressed, the appropriate indicator light for this value is illuminated and, preferably, a tone is sounded which is equivalent to the value selected.
  • the tones may be selected so that even a patient who is not looking at the handset 20 receives a good indication of the value selected.
  • the patient has both a visible and audible indication of the quantity of analgesic to be introduced. Provided the patient believes this is the order of relief required, he or she then presses a confirmation button 23 and the selected bolus dose is infused into the patient by means of a metering infusion pump.
  • a display or recording device normally a computer which may have a display to indicates the quantity of analgesic used, that is equivalent to the degree of pain being felt by the patient and the time when the material was introduced or which may log this information for examination by medical staff.
  • the analgesic shall control the pain for a period, the pain will later return, and subsequently the patient will again operate the handset.
  • the background infusion is only sustained according to handset activation. If there is insufficient activation of the handset over time, the rate of background infusion decays with time.
  • the system can be adjusted so that as the expected pain curve of the patient reduces, so the quantity of analgesic introduced on the selection of any position of the handset, will be reduced relative to that which would have been provided earlier in the process so that, in general terms, the quantity of analgesic is reduced.
  • the subsequent attempt to introduce more analgesia can be rejected and this can also be displayed to the carer.
  • the displays generated by the device can either be accessible adjacent to the patient or, more usually, at a nurses station or the like so that a degree of monitoring can be maintained without the carer having to visit the bedside of the patient unless they are otherwise called.
  • the system of the invention is such that the patient should be able to effectively control his or her pain over the period following the operation and the effect of the analgesia can work to provide protection to the current position to the pain curve.
  • ambulatory patients with chronic pain such as may occur in patients with cancer may be given a degree of control over their maintenance regime whilst at the same time, being prevented from deliberately overdosing with their medication and patients who go through periods of severe pain, such as when dressings are changed or the like can learn to adapt the level of analgesia to provide good pain control during and after the procedure.
  • the system can also be used for the control of other medications, for example, control of sedation or anaesthesia or the introduction of blood pressure control medication where the patient's perceived feelings are taken into account in adoption of the control system.

Abstract

La présente invention concerne un procédé permettant de contrôler l'administration de médicaments à un patient afin de le soulager. Ce procédé comprend un dispositif de commande (20) et une pompe (30). Ce dispositif de commande (20) qui permet au patient de sélectionner une quantité de médicament prédéterminée parmi l'un des numéros de sélection possibles (21), chacun d'entre eux correspondant à une quantité de médicament prédéterminée. Cette sélection met en route la pompe (30) qui commande l'administration de ladite quantité de médicament. Cette pompe est caractérisée par le fait que le patient peut, sur une période donnée, mettre en route à plusieurs reprises le dispositif de commande (20) afin de maintenir l'apport médicamenteux à une valeur variable et adaptative, qui soit optimum pour garder le contrôle de l'état du patient. Si le médicament est un analgésique, ce procédé peut maintenir le contrôle de la douleur proche d'un seuil délimité par une courbe de douleur du patient. Une commande (20) munie de sélections (21) allant des douleurs modérées aux douleurs fortes, permet au patient de sélectionner la dose d'analgésique prescrite.
