Description

A multi-way split blood drainage device

technical field

The utility model relates to a medical nursing appliance, in particular to a multi-channel split blood drainage device for drawing blood.

Background technique

Blood drawing in the hospital is a routine examination. Blood testing can detect various diseases, reflect the health status of the human body, and provide necessary auxiliary information for doctors to formulate treatment plans. Clinically, blood collection tubes are generally used for blood collection. The blood collection test tube is a transparent tube with a certain negative pressure inside and a soft plug on the upper port. When taking blood, the blood collection needle is passed through the stopper on the test tube, and the blood is collected into the blood collection tube under the action of negative pressure in the tube, and labeled for easy identification.

The current problem in the blood drawing process is that generally multiple samples need to be taken during the blood drawing inspection, that is, after enough samples are collected for one blood collection tube by blood collection, the blood collection tube is then pulled out and inserted into another blood collection tube. This blood drawing method not only prolongs the blood drawing time, but also easily causes blood pollution.

detailed description

According to the above-mentioned technical scheme, as shown in Fig. 1 and Fig. 2, the utility model discloses a multi-way split blood drainage device, which includes a puncture needle 1, and the rear end of the puncture needle 1 is connected with a threaded joint 3 through a hose , the threaded joint 3 is detachably provided with a plug valve 4, the plug valve 4 is detachably connected with an introducer, and the end of the introducer is provided with a blood collection cavity 10; The connector 3, the plug valve 4, and the introducer enter the blood collection cavity 10, and then lead to different blood collection tubes 14 through the guide needles.

The structure of the utility model is as shown in Figure 1, and the overall effect diagram is shown in Figure 2. In this structure provided by the utility model, what is used to puncture into the venous blood vessel for blood collection is the puncture needle 1, which has a butterfly wing 2 for easy operation. The rear part of the puncture needle 1 is connected with a plug valve 4 through a flexible pipe. This design structure mainly considers that it can be directly connected to the infusion set for intravenous injection after the blood collection is completed, so as to avoid re-puncture and improve efficiency. The application of the plug valve 4 can avoid possible infection caused by multiple punctures, and also relieves the pain of the patient. Of course, the plug valve 4 is optional, and can be removed from the threaded joint 3 if not needed. The threaded joint 3 ensures the convenience and tightness of the connection. Plug valve 4 is a circular tubular structure, and the inside is hollow, and one end is provided with external threads, and the other end is blocked by a rubber sheet. During use, the introducer is passed through the rubber sheet of the plug valve 4 to the inside, and after being pulled out, the blood will not overflow due to the elasticity of the rubber.

In this solution, since multiple tubes of blood samples need to be collected at one time, it is first necessary to guide the blood to a location, and then divert it as needed. For this reason, an introducer structure is provided, and after the introducer is inserted into the plug valve 4, blood enters into the blood-collecting cavity 10 of the introducer. At this time, if the blood needs to be shunted, the lead needles are connected to different blood collection tubes 14 respectively, so that multiple samples can be collected at one time.

As shown in Figure 1, the introducer includes a connector head 8 with a sharp front end, and a baffle plate is arranged at the end of the connector head 8; The blood collection chamber 10 described above; that is, the introducer passes through the plug valve 4 and penetrates into the flexible pipe during use, so that the blood in the flexible pipe can flow into the blood collection chamber 10 in turn. The setting of baffle plate plays a position-limiting effect, prevents connector 8 from piercing too deeply. A blocking clip is arranged on the connecting tube 9, which can temporarily block the blood flow in the connecting tube 9 when the blood collection tube is almost full, so as to facilitate pulling out the lead needle.

The top and side surfaces of the blood collection cavity 10 are hard structures, and the bottom surface of the blood collection cavity 10 is a soft structure; the blood collection cavity 10 is a transparent hollow structure. The blood collecting chamber 10 is transparent, so it is convenient to observe the amount of blood therein. Its bottom surface is a soft structure, which is to facilitate the insertion of the lead pin. For this reason, it is most suitable to arrange the blood collection chamber 10 in a disc shape. In the example shown in Figure 2, if three blood samples need to be collected at one time, three lead needles are required to penetrate into the blood collection chamber 10 through the bottom surface of the blood collection chamber 10 respectively, and then connect with the blood collection tube 14. Can. There is negative pressure in the blood collection tube 14 , and blood is collected into the blood collection tube 14 under the action of the negative pressure. The lead needle plays a guiding role, and the lead needle includes a minute needle head 5, and the minute needle head 5 connects a guide tube 7 that can pierce the blood collection tube 14 top cover through the delivery tube 6, and the end of the guide tube is sharp.

When taking blood, in order to facilitate the placement of the blood collection tube 14 and the observation of the blood collection process, the drainage device also includes an insertion barrel 12, and a plurality of jacks 11 are distributed on the insertion barrel 12; The insertion hole 11 is connected to the observation window 13 , the blood collection tube 14 is inserted into the insertion hole 11 , and the top cover of the blood collection tube 14 is located on the top surface of the insertion barrel 12 after insertion. Before blood collection, the blood collection tube 14 is inserted into the insertion barrel 12, and then punctured and connected. Whether the amount of blood in the blood collection tube 14 is sufficient can be observed through the observation window 13 .
