Abstract

The utility model provides a multifunction pleural cavity puncture needle and a fine catheter drainage device. A pleural cavity puncture needle is formed by a tube-shaped needle with a detection needle tube and a biopsy needle; the end of the tube-shaped needle handle is provided with a sealed valve capable of penetration, and the needle head is in sharp shape capable of penetrating into the body. The fine catheter drainage device is formed by a needle head, a fine catheter and a medical T-piece; the fine catheter is inserted into the human body through the puncture needle, and the point of the needle head is connected with the fine catheter inserted into the body, and the end of the needle head is connected with the medical T-piece; moreover, one end in the fine catheter is a sealed end head, and the tube wall close to the end head is opened with a drainage hole. By penetrating into the pleural cavity once, the device can extract the pleural tissue by biopsy, or can, after the fine catheter enters the body through the sealed valve of the tube-shaped needle, perform such curative methods as liquid drainage of the pleural cavity, washing and drug administration, thereby greatly releasing the pain of the patient and the workload of the doctor. Besides, apart from being safe, healthy and convenient, the utility model releases the economic burden of the sufferer and increases the social benefits.

Description

Multipurpose pleural space puncture needle and fine duct drainage system thereof

Technical field

This utility model relates to a kind of medical pleura puncture needle, particularly a kind of multipurpose pleural space puncture needle and fine duct drainage system thereof.

Background technology

At present in division of chest disease's disease, the pleural effusion case that causes because of a variety of causes bosom gets more and more, extracting pleural effusion in clinical treatment all adopts normally used large size syringe needle to be equipped with the needle tubing puncture suction, when a large amount of hydrops of pleural space, for guaranteeing safety, need the repeated localised puncture suction, and all need carry out the X-x ray fluoroscopy x before each puncture or take the photograph X-light rabat and the ultrasound investigation location, bring very big misery and financial burden to patient.In clinical, need carry out the check of pleura biological tissue in addition in addition, existing method is to adopt the biopsy needle that is made of the trocar and the thorn core pin that interts to carry out the pleural space puncture, and it is to extract biological tissue by the extruding dissection between core pin and needle tubing after needle body thrusts pleural space.Once unsuccessful when such extruding is cut with, also to carry out secondary or three punctures, bring very big misery to patient equally.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of easy to use, the painful little multipurpose pleural space puncture needle and the fine duct drainage system thereof that cause to patient.

The technology case that this utility model adopted is: multipurpose pleural space puncture needle, comprise by the cast pin that has handle, have on the handle and its whole detection needle tubing that is connected, the tube chamber that detects needle tubing is communicated with the pin chamber of cast pin, but be provided with the seal valve of break-through at the inserting needle mouth place of handle, and be fixed on the inserting needle mouth place of handle by the gland that has the hole of threading a needle, a termination that also is provided with the pin chamber that can insert the cast pin and exposes its pin chamber is that barb-shaped angle fluting, the other end are the biopsy needle of handle, and the syringe needle of cast pin is for penetrating the sharp shape of the human body.

A kind of fine duct drainage system, be to constitute by syringe needle and fine duct and medical threeway, the needle point of its syringe needle with insert intravital fine duct by the multipurpose thoracentesis needle and link to each other, the afterbody of syringe needle links to each other with medical threeway, the other end that is inserted in the fine duct on the syringe needle is a closed end, and the tube wall place of close this termination has the hole in order to drain.

This utility model is owing to only once penetrate the human body pleural space with the cast pin, can carry out the extraction of pleural space liquid, or after the seal valve of fine duct by the cast pin passed the cast pin, again the cast pin is extracted, can carry out pleural effusion drain, flushing and administration.If biopsy needle is inserted the cast pin to extend in the pleural space, can carry out biopsy and extract pleura.Thereby alleviated patient's misery and doctor loaded down with trivial details work in treatment greatly.Therefore, it is safe, healthy and convenient that this utility model uses, and reduces the working doctor amount, reduces the patient suffering.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, multipurpose pleural space puncture needle, comprise by the cast pin 1 that has handle 2, the syringe needle of cast pin 1 is for penetrating the sharp shape of the human body, have on the handle 2 and its whole detection needle tubing 3 that is connected, the tube chamber that detects needle tubing 3 is communicated with the pin chamber of cast pin 1, but be provided with the seal valve 7 of break-through at the inserting needle mouth place of handle 2, and be fixed on the inserting needle mouth place of handle 2 by the gland 10 that has the hole of threading a needle, also be provided with the pin chamber that can insert cast pin 1, and a termination of exposing its pin chamber is barb-shaped angle fluting 6, the other end is the biopsy needle 4 of handle 5.

Shown in Fig. 5, Fig. 6 a, Fig. 6 b, Fig. 6 c, seal valve 7 is a cavity T shape, in the bottom portion 8 of its cavity T shape at least two otch that intersect 9 is arranged.Present embodiment has three kinds of otch, promptly+, Y and M shape.
