Description

An intracranial hematoma drainage tube with continuous intracranial pressure monitoring

Technical Field

The utility model belongs to the technical field of neurology, and in particular relates to an intracranial hematoma drainage tube capable of continuously monitoring intracranial pressure.

Background technique

The dynamic change of intracranial pressure is an important indicator for understanding the changes in the condition of patients with external ventricular drainage. Continuous and accurate monitoring of intracranial pressure can provide a reliable basis for clinical diagnosis and treatment.

If intracranial pressure monitoring is required during clinical intracranial drainage, the traditional treatment method can only use secondary catheterization, one for drainage and one for monitoring. This not only makes the operation procedures cumbersome for medical staff, but also increases the pain of patients and surgical costs. Multiple openings are also more prone to infection. In addition, traditional intracranial pressure monitoring is to drain cerebrospinal fluid to an external pressure sensor device for measurement, which has the risk of damaging brain tissue, and when the brain is severely compressed and the ventricles are displaced or flattened, it is impossible to drain and measure pressure.

Therefore, Chinese patent CN 201978307 U discloses a drainage catheter capable of monitoring intracranial pressure, which relates to a neurological medical instrument. The catheter is provided with a drainage catheter body, one end of which is a drainage end, a drainage hole is provided on the side wall of the drainage end, the head of the drainage end is a blind end, and a pressure sensing device capable of measuring the surrounding liquid pressure is provided on the blind end. The other end of the drainage catheter is divided into two branches, and a data transmission line of the pressure sensing device is led out through one branch and connected with a pressure measuring detection connector, and the other branch is a drainage tube, and a Luer connector is connected to the end of the drainage tube; the pressure sensor device is mainly used to enter with the drainage tube for monitoring, but the inventor has found that the setting of the pressure sensor device may squeeze the pressure sensor when the intracranial pressure is large. Since the pressure sensor is made of hard material, squeezing of the intracranial tissue may occur, which poses a certain risk. At the same time, the pressure sensor is not easy to remove after installation. If a monitoring failure occurs, the overall drainage catheter needs to be replaced, which increases the cost and can be further improved.

Detailed ways

In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

Please refer to Figures 1 to 5 at the same time. The intracranial hematoma drainage tube for sustainable intracranial pressure monitoring according to the embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the intracranial hematoma drainage tube 1 with continuous intracranial pressure monitoring includes a drainage tube 1, which is characterized in that an intracranial pressure monitoring balloon 2 is placed inside the drainage tube 1, and the intracranial pressure monitoring balloon 2 is located inside the blind end of the drainage tube 1. The intracranial pressure monitoring balloon 2 is connected to a guide tube 3, and the guide tube 3 extends out of the intracranial pressure monitoring balloon 2 away from the end of the intracranial pressure monitoring balloon 2. A pressure monitoring box 4 is plugged into the extended end, and a bidirectionally movable reference block 5 is provided inside the pressure monitoring box 4, and the pressure monitoring box 4 is filled with water.

The reference block 5 is made of foam material, which can float in water and can be driven to move by a small thrust, thereby improving the accuracy of pressure monitoring of the drainage tube 1.

In this embodiment, the guide tube 3 provided therein can extend from the end of the drainage tube 1, or can extend from the side of the guide tube 3, and the guide tube 3 provided is long enough, and the guide tube 3 can be extended and connected with the pressure monitoring box 4 to ensure that the pressure monitoring box 4 can be placed in a horizontal position.

When the drainage tube 1 enters the patient's skull, the internal intracranial pressure monitoring balloon 2 is in a filled state. Since a first introduction tube 6 is fixedly connected to the end of the guide tube 3 near the pressure monitoring box 4, a tube cover 7 is inserted on the first introduction tube 6, and a number of air holes 8 are opened on the tube cover 7, before entering the patient's skull, the tube cover 7 can be removed, and water can be introduced along the first introduction tube 6 to fill the intracranial pressure monitoring balloon with water. At this time, place the pressure monitoring box 4 on a horizontal table or bed, ensure that the reference block 5 inside it is at the 0 scale position, and place it together with the drainage tube 1 in the patient's skull.

The upper end of the pressure monitoring box 4 is fixedly connected to a second introduction tube 9, and the second introduction tube 9 is plugged with a similar tube cover 7, so that water can be introduced along the second introduction tube 9, so that the reference block 5 is in a floating state. The pressure monitoring box 4 is embedded with a waist-shaped transparent sheet 10 on the side facing the second introduction tube 9, and scale bars 11 engraved on the pressure monitoring box 4 are provided on both sides of the waist-shaped transparent sheet 10. Guide rods 12 are fixed at both ends of the reference block 5, and the ends of the guide rods 12 away from the reference block 5 are extended out of the pressure monitoring box 4, and the ends extended out of the pressure monitoring box 4 are fixed with trigger plates 13.

After the drainage tube 1 enters the patient's skull, if the intracranial pressure increases, the intracranial pressure monitoring balloon 2 is squeezed. After squeezing, the water inside flows along the guide tube 3, thereby pushing the above-mentioned trigger plate 13 to move, driving the guide rod 12 to move, and then the reference block 5 can move toward the end away from the guide tube 3; if the intracranial pressure decreases, the water inside the guide tube 3 flows along the guide tube 3, moving toward the end of the intracranial pressure monitoring balloon 2, thereby driving the above-mentioned trigger plate 13 to move, driving the guide rod 12 to move, and then the reference block 5 can move toward the end close to the guide tube 3; therefore, the above two situations can intuitively judge the changes in the patient's intracranial pressure, and at the same time, a scale bar 11 is set for reference, which can facilitate the doctor's judgment.

In particular, since the first inlet pipe 6 and the second inlet pipe 9 are both provided with a pipe cover 7, and the pipe cover 7 is provided with an air hole 8, under a natural state, the internal pressure of the guide pipe 3 is consistent with the external pressure, so the water inside the guide pipe 3 can flow, and the above function can be achieved.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
