Abstract

The utility model belongs to the technical field of valves particularly suitable for medical use. The thoracic-abdominal puncture needle valve comprises a valve body, a needle seat communicated with the valve body, a injector barrel socket communicated with the valve body, a row-hole integrated with the valve body, a valve core installed inside the valve body, a rotating shaft with one end integrated with the valve core and the other end protruding out of the valve body, a handle installed on the out-protruding end of the rotating shaft, and a needle communicated with the needle seat. With the puncture needle valve, one single person can perform all work of puncture, not only saving manpower but also improving the speed of puncture.

Description

The Thoracicoabdominal puncture needle-valve

This utility model belongs to the technical field that is particularly suitable for medical valve.

Carry out the puncture needle that thoracic cavity or abdominal paracentesis are used to the patient in the hospital now, it all is the outer one section rubber tube of adjunction of a big syringe needle, when puncturing to the patient, want medical matters personnel to take syringe needle to puncture to the patient, medical matters personnel take mosquito forceps to clamp rubber tube, two people to work, and whenever exhaust once, a people must clamp rubber tube with mosquito forceps, and another people pulls up needle tubing, and body fluid is drained.Not only time-consuming but also bother, strengthened medical worker's workload greatly.

The purpose of this utility model provides the Thoracicoabdominal puncture needle-valve that people of a kind of usefulness can finish whole puncture workings.

This Thoracicoabdominal puncture needle-valve comprises valve body, and valve body is communicated with needle holder, and the needle tubing socket is communicated with valve body, and with the round that valve body is connected as a single entity, spool is contained in the valve body, and an end and the spool end that is connected as a single entity passes the rotating shaft of valve body.

Because spool and valve body are arranged, needle tubing is inserted on the needle tubing socket, one people holds valve body and needle tubing just can puncture, fitting inside the back can extracting bodily fluid once changing hands handle, one change hands handle again after taking out full needle tubing, spool is followed handle and is rotated, and makes between needle holder and the needle tubing socket to disconnect, and is communicated with between needle tubing socket and the round, body fluid in the needle tubing is discharged in round, and then turning handle, round and needle tubing socket disconnect, and the needle tubing socket is communicated with needle holder, repeat the operation of front, a people just can finish whole puncture workings, has both saved operator, has accelerated puncture speed again.

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure cuts open in the office of facing that Figure 1 shows that the Thoracicoabdominal puncture needle-valve;

Figure 2 shows that along the cutaway view of A-A line shown in Figure 1;

Thoracicoabdominal puncture needle-valve as shown in the figure comprises valve body 3, and valve body 3 is communicated with needle holder 7, and needle tubing socket 4 is communicated with valve body 3, and the round 6 with valve body 3 is connected as a single entity is equipped with spool 5 in valve body 3, and spool 5 is a three-way valve core.One end and spool 5 end that is connected as a single entity passes the rotating shaft 2 of valve body 3.Be fixed on handle 1 in the rotating shaft 2 with screw

In use, turning handle, three-way valve core are communicated with needle holder and needle tubing socket, and block round, thereby extracting bodily fluid in needle tubing, take out full needle tubing after, turning handle, three-way valve core is communicated with needle tubing socket and round, and blocks needle holder, thereby discharges body fluid from round.So repeatable operation one people can extract body fluid quickly and easily.

Claims

1 one kinds of Thoracicoabdominal puncture needle-valves, comprise valve body (3), it is characterized in that valve body (3) is communicated with needle holder (7), needle tubing socket (4) is communicated with valve body (3), the round (6) that is connected as a single entity with valve body (3), spool (5) is contained in the valve body (3), and an end and spool (5) end that is connected as a single entity passes the rotating shaft (2) of valve body (3).
