Abstract
The utility model discloses a combined needle for thoracic or abdominal paracentesis, and belongs to a medical instrument for thoracic or abdominal paracentesis. It comprises a plastic flexible needle, a built-in needle and a needle seat. The plastic flexible needle is connected to the needle seat in its bottom. The needle seat is provided with a rubber plug. The built-in needle is fitted with a handle in its bottom and passes axially through the rubber plug to be insertedly fix in the needle seat. There is a space between the rubber plug and the connection terminal of plastic flexible needle inside the needle seat and the, which is connected to the syringe adapter via a branch tube. As compared with the prior art, the utility model is easily operated to drain fluids after paracentesis, and overcomes the problem of air invasion into human body via three-way pipe for medical use. It is widely used for drainage of pleural fluid or ascites.
Description
Technical field
This utility model relates to medical splanchnocoel Centesis instrument, especially a kind of combined type splanchnocoel puncture needle that is used for hydrothorax, ascites catheter drainage.
Background technology
In the prior art, clinical when carrying out hydrothorax, ascites drain, use the conventional metals puncture needle mostly.But have many deficiencies on it uses: 1. hydrothorax, ascites generally increase comparatively fast, and traditional splanchnocoel puncture needle is subjected to the restriction of drawing liquid amount, will repeat repeatedly tapping inevitably, needs repeated localised puncture to take out pus especially for empyema; 2. traditional puncture needle is a metal needle, the risk that punctures lungs is not only arranged when inserting needle, realize repeatedly drain of one-time puncture in the body but also can't keep somewhere, and disposable a large amount of tapping might produce pulmonary edema or circulatory disturbance, so repeated localised puncture is difficult to avoid to the very big misery that the patient brings.In order to address the above problem, in publication number is the patent documentation of CN 2576239Y a kind of multi-functional puncture irrigation and drainage device is disclosed.Puncture needle is made of plastic flexible pipe and metal trocar in this technology, joins by medical threeway and drainage tube, plastic flexible pipe can be kept somewhere in the body during use, has overcome the deficiency of common puncture needle to a certain extent.But its mechanism is very complicated, " need screw off the drainage tube after the threeway during puncture drainage earlier; insert trocar and screw from the threeway metapore ...; when puncture needle by behind the pleuroperitoneal cavity, screw off trocar and close threeway simultaneously, connect and screw drainage tube; open threeway; " just enter drainage procedure then, have carelessness just might cause in a large amount of air admission bodies in the operating process slightly, jeopardize patient's life security.
Summary of the invention
Technical assignment of the present utility model is to provide a kind of combined type splanchnocoel puncture needle at above-mentioned deficiency of the prior art, this splanchnocoel puncture needle is easy to use, just the soft pin of plastics can be retained in thoracic cavity or intraperitoneal behind the one-time puncture, and overcome and use medical threeway space-time air-capacitor easily to enter intravital deficiency.
The technical scheme that its technical problem that solves this utility model adopts is: combined type splanchnocoel puncture needle, comprise the soft pin of plastics, built-in pin and needle stand, the base portion and the needle stand of the soft pin of plastics join, the built-in needle shaft that the bottom is fixed with handle is to being plugged among the soft pin of needle stand and plastics, be characterized in needle stand, being provided with rubber closure, built-in needle shaft leaves cavity between soft pin link of plastics and the rubber closure to passing rubber closure in the needle stand, and cavity joins by arm and syringe adapter.
Syringe adapter is provided with access flap.
Arm is provided with current-limiting apparatus.
Vertical needle stand axially is provided with location-plate on needle stand.
Combined type splanchnocoel puncture needle of the present utility model is compared with prior art, has following outstanding beneficial effect:
(1) is provided with when the soft pin of plastics can be avoided thoracentesis and punctures the risk of lungs, and can keep somewhere in the body, realize one-time puncture drawing liquid at any time, alleviated patient's misery, avoided the issuable danger of a large amount of tapping.
(2) insertion of built-in pin, extract with drainage procedure and use different routes, operating process is simple, the intravital probability of air admission when having eliminated operation.
(3) carry and use more convenient than the empyema drainage device.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model combined type splanchnocoel puncture needle;
Accompanying drawing 3 is that combined type splanchnocoel puncture needle A place structure for amplifying partly cuts open figure among Fig. 1.
The specific embodiment
Explain below with reference to Figure of description combined type splanchnocoel puncture needle of the present utility model being done.
Combined type splanchnocoel puncture needle of the present utility model mainly is made of the soft pin 1 of plastics, needle stand 2, built-in pin 3, syringe adapter 4 and location-plate 11.
Location-plate 11 is fixed on needle stand 2 tops, the base portion of the soft pin 1 of plastics passes location-plate 11 and fixes with needle stand 2, be provided with rubber closure 5 in the needle stand 2, built-in pin 3 axially passes rubber closure 5 and is plugged among the soft pin 1 of needle stand 2, location-plate 11 and plastics, is fixed with handle 6 in the bottom of built-in pin 3.Leave cavity 7 between the link of the soft pin 1 of plastics and the rubber closure 5 in the needle stand 2, cavity 7 joins by arm 8 and syringe adapter 4, and syringe adapter 4 is provided with access flap 9, and arm 8 is provided with current-limiting apparatus 10.
In the time of need carrying out puncture drainage, at first utilize puncture needle to carry out puncture procedure, after puncture needle just enters the thoracic cavity, just extract built-in pin 3, and then plastics pin 1 is pushed in the body fully, can better avoid stabbing pulmonary like this.After puncturing successfully, utilize medical adhesive tape puncture needle to be cemented in the patient site of puncture by location-plate 11, then syringe adapter 4 and syringe or drainage device are joined, transfer to built-in pin 3, the path that just can utilize the soft pin 1 of plastics, cavity 7 and arm 8 to constitute has carried out drainage procedure.This moment is because be rubber closure 5 in the needle stand 3, so air can not enter in the body by this path.After drainage procedure is finished, utilize current-limiting apparatus 10 to nip off arm 8 paths, dial down syringe or drainage device then, syringe adapter 4 is added access flap 9 sealings get final product.In the time of need carrying out multiple drainage procedure once more, only syringe or drainage device need be connected on the syringe adapter 4 and just can operate.
Its processing and fabricating of combined type splanchnocoel puncture needle of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of description, be the known technology of those skilled in the art.
