Embodiment 1

[0023] See Figure 1 to Figure 4 , the drainage tube includes a circular tube body 1 with a closed front end and an open rear end. A miniature pressure sensor 3 is arranged at the front end of the tube body 1. The material of the tube body 1 is medical grade elastic solid silicone rubber or medical grade PVC. The front side of the pipe body 1 has three outwardly convex arc-shaped strips 11 arranged at intervals in the circumferential direction, and there is a gap 12 between every two adjacent arc-shaped strips 11, and the length direction of the chord corresponding to the arc-shaped strips 11 corresponds The axial direction of the pipe body 1 is consistent, and each gap 12 is connected with the lumen 2 of the largest diameter in the pipe body 1, and the ratio of the largest diameter of the lumen 2 to the length of the chord is 1:6 ( To clarify the problem more clearly, in Figure 1 to Figure 4 Among them, the pipe body 1 and the arc strip 11 are not actually shown according t...

Embodiment 2

[0027] see Figure 5 to Figure 7 The drainage tube includes a circular tube body 1 with a closed front end and an open rear end. A miniature pressure sensor 3 is placed on the side wall near the lumen 2 at the front end of the tube body 1. The material of the tube body 1 is medical grade elastic solid Silicone rubber or medical grade PVC. The front side of the pipe body 1 has four outwardly convex arc-shaped strips 11 arranged at intervals in the circumferential direction, and there is a gap 12 between every two adjacent arc-shaped strips 11. The length direction of the chord corresponding to the arc-shaped strips 11 is the The axial direction of the pipe body 1 is consistent, and each gap 12 is connected with the lumen 2 of the largest diameter in the pipe body 1, and the ratio of the largest diameter of the lumen 2 to the length of the chord is 1:3 ( To clarify the problem more clearly, in Figure 5 to Figure 7 Among them, the pipe body 1 and the arc strip 11 are not actua...

Embodiment 3

[0031] see Figure 8 , the drainage tube includes a circular tube body 1 with a closed front end and an open rear end. A miniature pressure sensor 3 is arranged at the front end of the tube body 1. The material of the tube body 1 is medical grade elastic solid silicone rubber or medical grade PVC. The front side of the pipe body 1 is provided with several small holes 14 arranged at intervals in the circumferential direction, and the ratio of the maximum pipe diameter of the pipe body 1 to the diameter of the small holes 14 is 3:1.

[0032] In the above-mentioned embodiments, the structure of the front end of the drainage tube is different, but the tube body 1 is the same, and the inside of the tube body 1 is provided with several lumens 2 with different diameters, and at least one of the lumens 2 penetrates There are wires connecting the miniature pressure sensor 3 and the external signal processor 4 . see Figure 9 , during puncture, the rear end of the drainage tube is con...

Abstract

The invention discloses an intracranial hematoma drainage tube capable of measuring the cranium pressure. The intracranial hematoma drainage tube comprises a circular tube body with the front end closed and the back end open, a plurality of tube cavities with different diameters are formed in the tube body, a mini-type pressure sensor is arranged at the front end of the tube body or the side wall of the part, close to the tube cavities, of the front end of the tube body, and at least one tube cavity is internally provided with a wire connecting the mini-type pressure sensor and an external signal processor in a penetrating mode. The intracranial hematoma drainage tube is simple in structure and good in drainage effect. Due to the fact that the mini-type pressure sensor is additionally arranged at the front end of the drainage tube, the intracranial pressure can be accurately measured in time while the hematoma is removed, intracranial hypertension and other complications in a drainage operation are prevented in advance, the pain suffered by a patient during ventricular puncturing is relieved, and the intracranial hematoma drainage tube is suitable for application and popularization.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an intracranial hematoma drainage tube capable of measuring intracranial pressure. Background technique [0002] In modern medical treatment, intracranial hematoma drainage will be used in time when there is a hematoma in the brain. Open the drainage tube. The drainage tube is made of elastic solid silicone rubber, which has good biocompatibility, is non-irritating to human tissue, non-toxic, has no allergic reaction, and has very little rejection of the body; it has good physical and chemical properties, and is compatible with body fluids and It can maintain its original elasticity and softness during tissue contact without being degraded, and is a fairly stable inert substance. When using the drainage tube, the puncture is achieved with the help of the guide needle. When puncturing or extubating the tube, the guide needle is inserted into the tube body of the drainage tube an...
