Abstract

A thoracic puncture indwelling needle without additive injure refers to a thoracic puncture needle. The utility model solves the problem of enlarging the infecting rate of the trivial operations of large wound and centre vein sleeve guiding caused by the thoracic puncture. The two ends of the handle are respectively connected to the needle and the connecting pipe; the connecting pipe is connected to the negative pressure pipe; the plastic needle is provided on the inputting end of the horizontal body; the rubber is provided on the outputting end of the horizontal body; a liquid extractor is provided on the output end of the base body; the horizontal body of the base is sleeved on the needle of the plastic needle; the unidirectional valve is provided at the rear end of the negative pressure pipe. The utility model increases the T-junction, which makes the plastic needle avoid the generation of the pneumothorax caused by the thoracic puncture indwelling chest pinning the ongoing drainage, repeated aspiration to avoid causing suffering to patients and to avoid the economic burden, long-term retention of the body rather than leave a larger scar closed drainage.

Description

Do not have negative damage and keep somewhere thoracic-puncture needle

Technical field

This utility model relates to a kind of puncture needle.

Background technology

Hydrothorax, pneumothorax, hydropneumothorax are common clinical signs; pleurocentesis is diagnostic method and the treatment means of using always; but because misoperation and puncture needle are very sharp keen; the spike pierces visceral pleura caused pneumothorax even crisis life when regular meeting caused breast to wear; for avoiding pneumothorax hydrops, pneumatosis can not be pumped, thereby influenced therapeutic effect.In addition, in the drainage of pleural cavity, the closed drainage wound is too big clinically, more obvious and loaded down with trivial details should not the grasp of central venous catheter drainage of pleural cavity operation of abnormal pigmentary deposit on the skin trace after, the probability of infection is increased, central venous catheter cost also very high (180 yuan every), the patient is difficult to bear.

The utility model content

The purpose of this utility model is to puncture visceral pleura and cause pneumothorax and drainage of pleural cavity to cause wound big and the operation of central venous catheter drainage of pleural cavity is loaded down with trivial details for solving thoracic-puncture needle, and the problem that the probability of infection is increased provides the negative damage of a kind of nothing to keep somewhere thoracic-puncture needle.

This utility model comprises draw point, hold needle handle, connection tube and negative pressure pipe, the draw point rear end with hold needle handle and be connected, the rear end of holding needle handle is connected with connection tube, the rear end of connection tube is connected with the negative pressure pipe, it also comprises threeway and check valve, threeway is by the threeway seat, the plastics pin, stifled and the liquid extracting device connecting leg composition of rubber, the plastics pin is arranged on the input of horizontal entire body of threeway seat, rubber blocks up on the outfan of the horizontal entire body that is arranged on the threeway seat, the liquid extracting device connecting leg is arranged on the outfan of branch entire body on the threeway seat, horizontal entire body in the threeway and plastics pin together are sleeved on the draw point, and check valve is arranged on the rear end of negative pressure pipe.

The utility model has the advantages that: one, because this utility model makes the plastics pin in the threeway can avoid thoracic-puncture needle to puncture the generation that visceral pleura causes pneumothorax having increased threeway on the draw point, and thoracic-puncture needle can be kept somewhere and carry out constant drainage, avoid repeated localised puncture to cause suffering and avoid economically burden to the patient, the long-term indwelling can not resemble closed drainage and stay big cicatrix in the body, and simple to operate a, pin is used more.Two, this utility model cost is than the cheap several times of central venous catheter.Three, this utility model is applicable to Respiratory Medicine, thoracic surgery, emergency department and other clinical departments, and this product also can be used for the treatment of seroperitoneum.

Description of drawings

Fig. 1 is an overall structure cutaway view of the present utility model, and Fig. 2 is the structure cutaway view of threeway 2.

The specific embodiment

The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, present embodiment comprises draw point 1, hold needle handle 3, connection tube 4 and negative pressure pipe 5, draw point 1 rear end with hold needle handle 3 and be connected, the rear end of holding needle handle 3 is connected with connection tube 4, the rear end of connection tube 4 is connected with negative pressure pipe 5, it also comprises threeway 2 and check valve 6, threeway 2 is by threeway seat 2-1, plastics pin 2-2, stifled 2-3 of rubber and liquid extracting device connecting leg 2-4 form, plastics pin 2-2 is arranged on the input of horizontal entire body 2-1-1 of threeway seat 2-1, the stifled 2-3 of rubber is arranged on the outfan of horizontal entire body 2-1-1 of threeway seat 2-1, liquid extracting device connecting leg 2-4 is arranged on the outfan of the last branch entire body 2-6 of threeway seat 2-1, horizontal entire body 2-1-1 in the threeway 2 and plastics pin 2-2 together are sleeved on the draw point 1, and check valve 6 is arranged on the rear end of negative pressure pipe 5.Check valve 6 can make negative pressure pipe 5 form negative pressure; The effect of drainage tube is played in the effect that puncture needle is promptly played in threeway 2 again, and threeway 2 simultaneously can also be retained in carries out long-term drain on the thoracic wall; The stifled 2-3 of rubber can prevent to extract draw point 1 metathorax water and flow out; Plastics pin 2-2 adopts soft flexible flexible plastic to make it can not puncture visceral pleura in pleural space with when lungs contact, and can pump the hydrops pneumatosis, also it can be kept somewhere on thoracic wall, continues drawing liquid drain repeatedly.

The specific embodiment two: in conjunction with Fig. 2 present embodiment is described, the front end of the plastics pin 2-2 of present embodiment is provided with needle point 2-2-1.Can not puncture visceral pleura because needle point 2-2-1 circle is blunt, reduce resistance when being convenient to plastics pin 2-2 simultaneously and entering thoracic wall.

During use, the draw point 1 that will have plastics pin 2-2 earlier thrusts the thoracic cavity, after treating the liquid suction negative pressure pipe 5 in the thoracic cavity, draw point 1 is extracted, threeway 2 still is retained in the thoracic cavity, flexible pipe on the liquid extracting device 7 is connected with liquid extracting device connecting leg 2-4, and hydrops enters in the liquid extracting device through liquid extracting device connecting leg 2-4 and flexible pipe 7 in the thoracic cavity.
