Description
Technical Field
The utility model relates to a thorax puncture needle in the research field of medical instruments, in particular to a portable thorax puncture needle designed for newborns and children.
Background
Currently, the thorax puncture needles commonly used in clinic are divided into two types. The first type of thoracic cavity puncture needle guides puncture through a real puncture needle in the middle of a sleeve, and after the puncture is successful, the real puncture needle is used as a guide to place a drainage tube into a thoracic cavity. The puncture needle faces several problems in the clinical practical process: firstly, the puncture needle is solid metal and only has a puncture function, and before puncture, an injector is needed to carry out infiltration anesthesia on skin and subcutaneous tissues, so that the operation steps are multiple, the potential safety hazard is large, and the intercostal blood vessels and nerves are easily damaged by multiple punctures; secondly, the distal end of the puncture tube is of a straight structure, and in the indwelling process, due to the re-expansion of lung tissues, the lung tissues are easy to be in close contact with the puncture tube, so that the drainage is not smooth or the puncture tube is folded and blocked, and the drainage effect is seriously influenced; thirdly, the method comprises the following steps: the puncture needle model is too large, and has great difference with the chest wall anatomical structure of neonate or children, and the puncture needle of this type does not have the puncture needle model special for neonate or children at present, uses adult's puncture needle, has the injury chest wall probably, and pneumothorax is one of neonate or children's common disease at present, and the condition of illness is urgent, often needs urgent catheterization, and often faces the puzzlement that does not have suitable puncture needle available clinically. The second type of thoracentesis needle is mainly used for deep vein catheterization, and because of the thin catheter and small wound, the second type of thoracentesis needle is often used for thoracentesis catheterization to drain thoracic fluid and gas, and the second type of thoracentesis needle is mainly used for placing a drainage tube into the thoracic cavity through the guidance of a guide wire. The puncture needle faces several problems in the clinical practical process: firstly, the range of the initial design and application of the traditional Chinese medicine is central venous catheterization transfusion and venous transfusion channel establishment, the traditional Chinese medicine is not designed aiming at the flow of thoracocentesis and the characteristics of the chest wall, the guide wire is too long, the guide wire is easy to leave a sterile area and pollute wounds when the too long guide wire is found in the clinical practical process, and the practical operation and use are difficult; secondly, the catheter is too few in opening, and partial type does not have the side opening, and drainage speed is slow, drainage effect is poor, often leads to lumen blocking, needs twice or even replaces the catheter many times, and very big aggravation patient's burden increases and has the operation risk of creating, and the actual application effect is poor.
SUMMERY OF THE UTILITY MODEL
In order to overcome the problems that no puncture tube with a proper type is available in the chest puncture tube placement process of the neonate or the child at present, the operation process is too complicated and is not beneficial to tube placement under emergency conditions, the far end of the puncture tube is easy to contact with lung tissues to cause unsmooth drainage, the drainage speed is low due to no side holes or a small number of side holes, the guide wire is too long, the practicability is not high, multiple tube placement is frequently encountered, and the like, the utility model provides a portable chest puncture needle which is designed according to the anatomical characteristics of the chest wall of the neonate or the child, and has the advantages that the requirement of tube placement of the neonate or the child is met according to the anatomical structure design of the; the puncture needle is designed according to clinical experience, has simple structure, convenient use, few puncture steps, high success rate, convenient puncture, small injury to the chest wall of a newborn and difficult folding, distortion and blockage during drainage; the application range is wide, and the device can be used for pneumothorax and hydrothorax and whether closed drainage is needed.
The utility model provides a solution of its technical problem is: portable thorax pjncture needle, including syringe needle, puncture gum cover and hose, sealed cap is installed to the one end of hose, and the other end of hose is connected with the puncture gum cover through connecting the pullover, a plurality of drainage holes have been arranged to the lateral wall of puncture gum cover, and the tail end flexible of puncture gum cover, the needle body of syringe needle can pass sealed cap, hose and the inside back of connecting the pullover in proper order, and the needle body is arranged puncture gum cover inside in.
As a further improvement of the technical scheme, the tail end of the injection needle head is exposed after penetrating through the puncture rubber sleeve.
As a further improvement of the technical scheme, the outer surface of the puncture rubber sleeve is provided with scale marks.
As a further improvement of the technical scheme, the hose is sleeved with a switch.
As a further improvement of the technical scheme, the length of the needle body of the injection needle head is 15-19 cm, and the length of the puncture rubber sleeve is 10-13 cm.
As a further improvement of the technical scheme, an external connection pipe is arranged on the side wall of the sealing cap, the external connection pipe and the sealing cap are arranged in a Y shape, and a sealing nut is screwed on the external connection pipe.
The utility model has the advantages that: the utility model discloses an injection syringe needle and puncture gum cover, the needle body of injection syringe needle can pass sealed cap, hose and the inside back of connecting the pullover in proper order, and inside the puncture gum cover was arranged in to the needle body, and the puncture gum cover was the linearity, can realize two functions of puncture and injection liquid medicine, and after the injection syringe needle took out, the tail end of puncture gum cover was the sinuous form, avoided appearing lung tissue and puncture pipe in close contact with, guaranteed that the drainage is unobstructed.
