Abstract
The utility model discloses an intracranial hematoma drainage tube. The intracranial hematoma drainage tube comprises a circular tube body. The front end of the round tube body is sealed, and the rear end of the round tube body is open. The tube body is made from elastic solid silicone rubber. A plurality of outwards-raised cambered strips is circumferentially distributed on the front side of the tube body at intervals. A notch is formed between every two adjacent cambered strips. The length trend of chords corresponding to the cambered strips is consistent with the axis trend of the tube body. Each nick is communicated with an inner hole of the tube body. The ratio of the diameter of the inner hole of the tube body to the lengths of the chords is in a range from 1:3 to 1:6. When the tube is punctured or drawn, a guide pin is inserted into the tube body, and contacts with the front end of the tube body, so that the cambered strips are forced to be elongated and fall back to form round section of the front side of the tube body. An axially extending strip-type groove is formed between every two adjacent cambered strips. The drainage tube has a good drainage effect.
Description
Technical field
This utility model relates to a kind of Intracranial hematoma drain tube.
Background technology
At present, the structure of existing Intracranial hematoma drain tube is: it comprises the circular body of front end sealing, rear end opening, the material of body is elastic solid (Hookean body) silicone rubber (being a kind of of medical silica-gel), the front side of body circumferentially arranges two symmetrical rounds, all have some along the spaced apart aperture of body axis direction in every round, the diameter of bore of body and the ratio of hole diameter are (2 ~ 4): 1, and as seen, the diameter of aperture is less;
Puncture or during tube drawing, guid needle insert in the body and with body before end in contact, the material of guid needle is generally titanium alloy or stainless steel material.
Elastic solid (Hookean body) silicone rubber has good biocompatibility, to tissue nonirritant, avirulence, few without anaphylaxis, body rejection; Having good physicochemical property, with body fluid and organize and can keep its original elasticity and pliability in the contact process, be not degraded, is a kind of inert substance of quite stable.Can be high temperature resistant, can sterilize.Machine-shaping is convenient, and easily processing engraving shape is easy to use.
Adopt existing Intracranial hematoma drain tube in the drain process, the clot of intracranial causes drain obstructed easily with aperture clogs, and this makes troubles for the nursing of patient's Craniotomy and inconvenience, also patient's rehabilitation speed and rehabilitation result is brought negative effect.
The utility model content
Technical problem to be solved in the utility model provides the better Intracranial hematoma drain tube of a kind of drainage effect.
For solving the problems of the technologies described above, this utility model provides a kind of Intracranial hematoma drain tube, and it comprises the circular body of front end sealing, rear end opening, and the material of body is elastic solid (Hookean body) silicone rubber;
There are circumferentially spaced apart some evagination arc strips the front side of body, between per two adjacent arc strips a gap is arranged all, arc strip the length trend of corresponding string move towards consistent with the axis of body, each gap all is communicated with the endoporus of body, and the ratio of the diameter of bore of body and the length of described string is 1:(3 ~ 6);
Puncture or during tube drawing, guid needle insert in the body and with body before end in contact, forces the arc strip elongation, falls after rise, so that the cross sectional shape of body front side be circular, and axially extended bar-shaped trough of formation between per two adjacent arc strips.
For the purpose of the concise description problem, below to Intracranial hematoma drain tube described in the utility model all referred to as this drainage tube.
During puncture, this drainage tube enters intracranial (at this moment by means of guid needle first, the cross sectional shape of body front side is circular), after guid needle is extracted in the body, the elastic restoring force that body has by himself, so that there are circumferentially spaced apart some evagination arc strips the front side of body, and forming circumferentially spaced apart some gap (at this moment, this drainage tube is the drain state after puncturing) under the effect that encloses of some arc strips.
As mentioned above as can be known, the ratio of the diameter of bore of body and the length of described string is 1:(3 ~ 6), and arc strip the length of corresponding string be the axis projection length of arc strip, therefore the axis projection length of arc strip is much larger than the diameter of bore of body, so that gap between per two adjacent arc strips, its axial length certainly will be also much larger than the diameter of bore of body.
Because of this, in the drain process, the clot of intracranial is difficult to stop up described gap, the clot that intracranial produces can be realized with arriving with row, the promptness of clot discharging is better, has eliminated to a certain extent the defective that affects this drainage tube drainage effect, so that the drain of this drainage tube is unobstructed, drainage effect is better.This offers convenience for the nursing of patient's Craniotomy, also patient's rehabilitation speed and rehabilitation result is brought positive influences.
The specification of described arc strip is identical, so that the specification of each gap is identical, the specification of each bar-shaped trough is also identical.Like this, this drainage tube is easy to processing, and cost is lower.
The quantity of described arc strip is three or four.Like this, this drainage tube simple in structure and reasonable, its axial respective strengths is better.
