Description

A platelet transfusion device

technical field

The utility model relates to a platelet transfusion device, which belongs to the field of medical equipment.

Background technique

At present, when the platelets prepared on the market are used clinically in hospitals, white blood cells need to be removed. The process includes the following steps: 1. Mix the prepared platelet bags into a larger platelet collection bag through sterile connection 2. Filter the platelets in multiple platelet bags through a white blood cell filter and transfer them to a platelet collection bag for storage; 3. In the hospital, use the platelets in the platelet collection bag through an infusion set for clinical use. Therefore, in the process, not only the whole platelet preparation and filtration process takes a long time and the cost is high, but also the waste of residual platelets in the bag will occur during the transfer of platelets between multiple bags. In addition, during the use of platelets, if the platelet collection bag When the platelets are not enough to use, it will be difficult to replenish the platelets, and the situation of replenishing the platelets by puncturing different bags multiple times with the same puncture device is prone to contamination.

Utility model content

The purpose of the invention of the present utility model is to provide a platelet infusion device for the above-mentioned existing problems, use the infusion device to directly take platelets and filter leukocytes, and then input them into the human body, which simplifies the clinical application of platelets. The injector can be connected to multiple platelet bags at the same time to prevent contamination caused by repeated insertion and withdrawal of the same trocar.

The technical scheme that the utility model adopts is as follows:

The utility model discloses a platelet infusion device, which comprises a first three-way, the right input end of the first three-way is connected with a bottle stopper puncture needle through a hose; the output end of the first three-way is connected in series with a drip Bucket, white blood cell filter, venous needle; the left input end of the first tee is connected with at least two puncture devices through flexible pipes.

As a preference: a multi-channel connector is provided between the first tee and the piercer, the multi-channel connector includes an output end and at least two input ends, and each input end of the multi-channel connector is connected to a piercer.

As a preference: the multi-channel connector is a five-way joint or a six-way joint.

As a preference: the multi-channel connector is composed of the second three-way, the third three-way and the fourth three-way in series, and has one output end and four input ends.

As a preference: a filter screen is provided in the dropping funnel.

As a preference: the cork puncture needle is provided with an exhaust device.

The connection of the above-mentioned components is realized by hose connection.

Due to the adoption of the above structure, the steps in the clinical use of platelets are simplified, and the time for platelets to be put into clinical use is saved. The platelet bag containing the platelet liquid can be directly transfused clinically, and filtered by a white blood cell filter, and multiple punctures can be performed. The design of the device can enable multiple platelet bags to provide platelets at the same time, avoiding the pollution caused by the multiple insertion and removal of different platelet bags with the same puncture device. In addition, flushing each platelet bag with physiological saline avoids residual waste of platelets. The filter in the drip funnel effectively filters blood clots to prevent the impact on the human body during infusion, and the exhaust device on the cork puncture needle ensures the normal infusion of normal saline and prevents the generation of negative pressure.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are: a platelet infusion device of the utility model has the characteristics of simple structure, strong versatility, easy operation, low cost and safe use.
