Abstract
The utility model discloses a thoracic drain needle which is provided with an air core, and the needle body can be internally sheathed with a needle core. The utility model is characterized in that: the rear end of the needle body is connected with a triangular valve; the needle body is provided with a curved front end. The beneficial effect is that: operation is convenient; drain work can be accomplished independently; muscle will not be cut and pulled by the thoracic drain needle. Bleeding is little; tissue trauma is small; safety factor is high. The needle point is parallel to the thoracic cavity and the lung tissue will not be hurt; pipes are not easy to be blocked. If pipes are blocked, a valve switch is loosened and the pipes are inserted into an internal core. Fixation is convenient and the thoracic drain needle is easy for patients to accept. Pipe drawing is convenient and the thoracoscope inspection can be operated by the thoracic drain needle directly; operation is simplified.
Description
Technical field:
This utility model relates to medical device technology, is a kind of liquid to be inputed or outputed the medical treatment device of human body, and specifically, be a kind of thoracic drainage needle.
Background technology:
Existing thoracic drainage needle all is a straight pipe type, open.This existing drainage needle is vertical the insertion when entering torso model, injures lung tissue easily, and the open end of drainage needle also causes the interior logistics of body to go out easily or external foreign body flows in the body.
Summary of the invention:
The purpose of this utility model provides a kind of easy to operate, goes out insufficiency of blood, and tissue injury is little, the safety coefficient height, especially can not injure lung tissue, be difficult for plugging, convenient fixing, patient easily accepts, and tube drawing is convenient and can directly carry out thoracoscopy by it, the thoracic drainage needle that simplifies the operation.
Technical solution of the present utility model is: a kind of thoracic drainage needle, have hollow and can in the needle body of cover nook closing member, it is characterized in that: needle rear end is connected to triangle vavle, needle body has crooked leading portion.
Needle body described in this utility model is connected by a connector with triangle vavle, and connector and needle body are fixed, and triangle vavle is loaded in the threaded connection hole on the connector.The crooked radian of the leading portion of needle body bending is 90 °; Bending radius is 25mm.A side conduction hole is arranged on the triangle vavle.The front end of needle body has sharp-pointed head, and the needle body leading portion side behind the head has conduction hole.
The beneficial effects of the utility model are: easy to operate, can independently finish the drain operation, and can not cause and cut or pull muscle, go out insufficiency of blood, tissue injury is little, the safety coefficient height, needle point is parallel with the thoracic cavity, especially can not injure lung tissue, be difficult for plugging, inject inner core again and get final product even plugging also only need be unclamped valve switch, convenient fixing, patient easily accepts, and tube drawing is convenient and can directly carry out thoracoscopy by it, simplifies the operation.
Below in conjunction with drawings and Examples this utility model is further described:
Description of drawings:
Accompanying drawing is the structural representation of a kind of thoracic drainage needle of the present utility model.
The specific embodiment:
Accompanying drawing has been described an embodiment of the present utility model, in this embodiment, have hollow and can in the needle body 1 of cover nook closing member, needle body 1 rear end is connected to triangle vavle 5, needle body 1 has crooked leading portion 3.Described needle body 1 and triangle vavle 5 are connected (or directly connecting) by a connector 4, and connector 4 and needle body 1 fixing (as welding), triangle vavle 5 are loaded in the threaded connection hole 6 on the connector 4.The crooked radian of the leading portion 3 of needle body 1 bending is 90 ° (or approaching angles); Bending radius is 25mm (or other approaching numerical value).A side conduction hole 9 is arranged on the triangle vavle 5.The front end of needle body 1 has sharp-pointed head 7, and the needle body leading portion side behind the head 7 has conduction hole 8.
This utility model can be used for the inaccessible drain of pneumothorax; Or the suction of hydrothorax, by external vacuum extractor, at the time of needs suction chest fluid; Or by administration in this utility model thoracic cavity.
This utility model after needs are done inaccessible drain place in thoracic cavity, carried out routine disinfection, drape, local anesthesia successfully, cuts the skin that is about 0.5cm in use with scalpel.Then drainage needle is put nook closing member and tighten back nut on the triangle vavle, the side conduction hole of triangle vavle connects silica gel tube outward, closes the triangle vavle switch.The first half for the treatment of drainage needle again enters that the radian along needle body inserts the thoracic cavity with needle body behind the thoracic cavity.Then sterile gauze is cut " Y " type cushioning at drainage needle between skin, and with the good drainage needle of wide immobilization with adhesive tape.Extract the drainage needle inner core, tighten the triangle vavle back nut, connect drainage bottle or drainage bag on demand, open the triangle vavle switch.
