Negative pressure suction type puncture drainage device
Technical Field
The utility model relates to the field of medical equipment, in particular to a negative pressure suction type puncture drainage device.
Background
In clinical practice, the marrow puncture, the collection of bodily fluids such as pleural effusion, ascites and cerebrospinal fluid all need to puncture the collection, medical personnel can use disposable venous blood taking needle to gather patient's venous blood sample this moment, and use anti-freezing syringe to gather patient's arterial blood sample, above operation need puncture 2 at least times to the patient, cause the pollution of blood sample when squeezing into the sample with the syringe after gathering, because the difference needs can carry out the collection of inserting the needle many times, still need to change the pipe that contains different anticoagulants and easily cause cross contamination.
SUMMERY OF THE UTILITY MODEL
For solving the problem that the background art exists, the utility model provides a negative pressure suction formula puncture drainage device has solved the problem of the pollution that causes blood sample when squeezing into the sample with the syringe after gathering, reduces the multiple spot and gathers to the volume of gathering is also unrestricted, makes the more convenient high efficiency of puncture.
In order to solve the technical problem, the utility model provides a following technical scheme:
the utility model relates to a negative pressure suction formula puncture drainage device, including pjncture needle, needle handle and needle lid, pjncture needle fixed mounting covers at the front end of needle handle and through the needle lid, the end of needle handle is arranged and is connected with Y type hose, and the vacuum tube has been arranged in to the one end activity of Y type hose, and the syringe has been arranged in to other end activity, installs first valve on the Y type hose of vacuum tube front end, installs the second valve on the Y type hose of syringe front end.
Furthermore, the surface of the puncture needle is marked with length scales.
Furthermore, the port of the Y-shaped hose connected with the vacuum tube is conical.
Furthermore, the Y-shaped hose is connected with the front end of the injector in a sleeving manner.
Furthermore, the needle handle is a cylinder with a needle wing on one side.
Compared with the prior art, the utility model discloses following beneficial effect has: the negative pressure suction type puncture drainage device is respectively connected with a vacuum tube and an injector through a Y-shaped hose through the design of double joints to carry out negative pressure suction; the syringe can draw out the gas in the Y-shaped hose and simultaneously draw out the sample to carry out smear detection on the glass slide.

In the figure: 1. puncturing needle; 2. a needle cover; 3. a needle handle; 4. a Y-shaped hose; 5. a first valve; 6. a vacuum tube; 7. a second valve; 8. a syringe.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in figure 1, the negative pressure suction type puncture drainage device comprises a puncture needle 1, a needle handle 3 and a needle cover 2, wherein the puncture needle 1 is fixedly arranged at the front end of the needle handle 3 and is covered by the needle cover 2, the tail end of the needle handle 3 is connected with a Y-shaped hose 4 in an inserting mode, one end of the Y-shaped hose 4 is movably inserted with a vacuum tube 6, the other end of the Y-shaped hose 4 is movably inserted with an injector 8, a first valve 5 is arranged on the Y-shaped hose 4 at the front end of the vacuum tube 6 and is used for controlling the connection and disconnection of the Y-shaped hose 4 between the puncture needle 1 and the vacuum tube 6, and a second valve 7 is arranged on the Y-shaped hose.
Wherein, the surface of the puncture needle 1 is marked with length scales, which is convenient for controlling the puncture depth.
The port of the Y-shaped hose 4 connected with the vacuum tube 6 is conical, so that the Y-shaped hose is conveniently connected with the vacuum tube 6.
Wherein, the Y-shaped hose 4 is connected with the front end of the injector 8 in a sleeving manner.
Wherein, the needle handle 3 is a cylinder with needle wings at one side, which is convenient for holding.
It is noted that the utility model relates to a negative pressure suction type puncture drainage device, when in operation, the needle cover 1 is firstly opened, and the second valve 7 is closed, the puncture needle 2 is punctured into the puncture point by holding the needle handle 3 after the puncture point is determined, the vacuum tube 6 is connected, the first valve 5 is opened, because the sample flows into the vacuum tube 6 through the puncture needle under the action of negative pressure, a plurality of tubes containing different anticoagulants can be replaced according to the detection requirement, so that the needle insertion and sampling for a plurality of times are avoided, meanwhile, the pipe distribution is not needed in the later period, the probability of cross contamination is reduced, the second valve 7 can be opened in consideration of the phenomenon of insufficient negative pressure or disappearance of the negative pressure, then a certain amount of gas is pumped out from the Y-shaped hose 4, the vacuum tube 6 is reused after the second valve 7 is closed, in addition, the syringe 8 can also suck a small amount of sample and drip the sample on a glass slide for smear detection directly.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
