Abstract

The utility model provides an intracranial hematoma sucking drainage device belonging to medical device, particularly applied in sucking and draining intracranial hematoma. The utility model is mainly composed of a drainage tube and a drainage catheter, and the end of the drainage tube is provided with a side hole. The utility model is characterized in that a tee pipe is also included for connecting the drainage tube and the drainage catheter, and the drainage tube is provided with a hard internal bushing, which serves as a guide pin when the drainage tube is placed in and supports the drainage tube when the hematoma is sucked, and postoperative urokinase injection is carried out with the tee pipe. The utility model has advantages of simple and practical structure, convenient and flexible operation and good applicability.

Description

The hematoma aspiration drainage system

Technical field this utility model belongs to medical apparatus and instruments, is a kind of be suction and drain medical apparatus behind the intracranial hematoma percutaneous puncture specifically.

The background technology percutaneous drainage has been widely used in the treatment hypertensive cerebral hemorrhage in recent years, and the postoperative haematoma cavity injects hematoma liquefier liquefaction, drain residual hematomas such as urokinase, and this method is effective, is comparatively effective method of treatment hypertensive cerebral hemorrhage.The drainage tube of using clinically is mainly common single chamber macromolecule medical catheter at present, but this kind conduit is not for intracranial hematoma operation dedicated conduits, need add in addition during use with metallic pin, drainage bag etc., function singleness.When drawing hematoma, because the effect of negative pressure, drainage tube presses off easily, influences normal running simultaneously.

Do not find to be exclusively used in the hematoma aspiration medical catheter at present as yet.

The summary of the invention the purpose of this utility model is to provide a kind of suction and drain intracranial hematoma hematoma aspiration drainage system of being exclusively used in.This utility model adopts following technical proposals for this reason: the hematoma aspiration drainage system, mainly to form by drainage tube, drainage catheter, and end two sides of drainage tube are provided with side opening, it is characterized in that: also comprise a tee T that can connect drainage tube and drainage catheter; Also be provided with a hard inner sleeve in drainage tube, the end of this inner sleeve also is provided with the side opening corresponding with above-mentioned side opening.After this utility model adopts above structure, owing to set up a hard inner sleeve in drainage tube, the guide pin effect when not only playing drainage tube and inserting also plays a part the supporting drainage pipe when drawing hematoma, prevent suction function and drainage tube is pressed off, aspirate convenient, fast.The tee T of setting up simultaneously can carry out the operation that postoperative injects urokinase, also can be through this tee T suction mediation when having clot to stop up drainage tube.Inner sleeve can direct external syringe, carries out drawing hematoma.When drainage tube passes through the external drainage catheter of tee T, can carry out the drain of hematoma.Have simple in structure, practical, easy to operate, flexible, the effect that usability is strong.This utility model is disposable products, and is easy to use, cost is low, is easy to promote.

Description of drawings Fig. 1 is a kind of structural representation of the present utility model; User mode reference diagram when Fig. 2 is drawing hematoma; User mode reference diagram when Fig. 3 is the hematoma drain.

In the specific embodiment accompanying drawing, 1 is that drainage tube, 2 is that inner sleeve, 3 is that drainage catheter, 4 is that tee T, 5 is that saline bottle, 6 is that plug, 7 is that liquid line, 8 is that escape pipe, 9 is that side opening, 10 is a cap nut.As shown in drawings, this utility model is a kind of hematoma aspiration and drain medical apparatus, mainly form by drainage tube 1, drainage catheter 3 and the Sterile Saline bottle 5 of plastic production, the end of drainage tube 1 is the cecum of sealing, simultaneously be respectively equipped with side opening 9, be used to aspirate and the hematoma of drain intracranial in these end two sides.Also be provided with the hard inner sleeve 2 that metal is made in drainage tube 1, also be provided with the side opening 9 corresponding with above-mentioned side opening 9 at the end of this inner sleeve 2, it is the joint of syringe that the other end is designed to insert the suction needle tubing; The diameter of inner sleeve 2 is slightly less than drainage tube 1.Behind sphenotresia, when drainage tube 1 was inserted haematoma cavity, inner sleeve 2 played a part guide pin because hardness is big, and supporting drainage pipe 1 is beneficial to inserting of drainage tube 1.When carrying out hematoma aspiration, inner sleeve 2 external syringes extract hematoma, and this moment, inner sleeve 2 played a part supporting drainage pipe 1, prevented that drainage tube 1 from pressing off because of negative pressure.The bottleneck of saline bottle 5 is provided with rubber closure, and saline bottle 5 is used to store drain liquid.Drainage catheter 3 is long plastic catheter, and end is provided with the plug 6 that rigid plastics is made, and plug 6 inserts in the above-mentioned rubber closure; Be provided with double lumen tube on plug 6, one of them communicates with plastic catheter for liquid line 7, is used for draining fluids, and another is an escape pipe 8, is used for the circulation of gas in the saline bottle 5.This utility model also comprises a tee T 4, and a mouth of pipe of this tee T 4 connects above-mentioned drainage tube 1, mouth of pipe and connects above-mentioned drainage catheter 3, the 3rd mouth of pipe place and be provided with sealing with cap nut 10.Postoperative such as need are injected urokinase, can open this cap nut 10, and from then on inject and gets final product the cap nut 10 of screwing on again after the injection at mouth of pipe place.When the needs drain, in drainage tube 1, take out inner sleeve 2, this moment, one end of drainage tube 1 was still stayed in the haematoma cavity, on the other end of drainage tube 1, connect tee T 4, connect drainage catheter 3 by tee T 4 again, the end that the other end of drainage catheter 3 promptly has a plug 6 inserts the rubber closure of saline bottle 5, and effusive liquid enters in the saline bottle 5 at last by drainage tube 1, tee T 4, drainage catheter 3 in the haematoma cavity.
