Description

A kind of platelet transfusion device

Technical field

This utility model relates to a kind of platelet transfusion device, belongs to medical instruments field.

Background technology

In the market for the preparation of good platelet when hospital clinical uses, need to remove leukocyte, this process comprises the following steps: 1, be mixed on a larger Thrombocyte collecting bag by the multiple platelet bags prepared respectively by aseptic plugging into; 2, transfer to after the platelet in multiple platelet bag being filtered by leukocyte depletion filter and be placed in Thrombocyte collecting bag and preserve; 3, within the hospital, the platelet in Thrombocyte collecting bag is carried out Clinical practice by infusion device.Therefore in process, not only whole to prepare the filter process time long for platelet, cost is high, and platelet can remain the waste situation generation of platelet in sack between multiple sack in transfer process, in addition in platelet use procedure, if when the platelet in Thrombocyte collecting bag uses not, there will be the situation that platelet is difficult to supplement and occur, supplement hematoblastic situation easily contamination phenomenon occurs by repeatedly the puncture mode of different sack of same perforator.

Utility model content

Goal of the invention of the present utility model is: for above-mentioned Problems existing, a kind of platelet transfusion device is provided, this infusion device is utilized directly to take platelet and leukocyte depletion, then human body is inputted, simplify the step of hematoblastic clinical practice, this infusion device can connect multiple platelet bag simultaneously, prevents same perforator from repeatedly plugging and pollutes.

The technical solution adopted in the utility model is as follows:

The utility model discloses a kind of platelet transfusion device, comprise the first threeway, the right input of described first threeway is by hose connection bottle cork needle; The outfan of the first threeway is in series with dropping funnel, leukocyte depletion filter, intravenous needle by flexible pipe; The left input of the first threeway has at least two perforators by hose connection.

As preferably: be provided with multichannel adapter between described first threeway and perforator, described multichannel adapter comprises an outfan and at least two inputs, and each input of this multichannel adapter connects a perforator.

As preferably: described multichannel adapter is five-way joint or six-way joint.

As preferably: described multichannel adapter is in series by the second threeway, the 3rd threeway and the 4th threeway, has an outfan and four inputs.

As preferably: be provided with drainage screen in described dropping funnel.

As preferably: described bottle cork needle is provided with exhaust apparatus.

The connection of above-mentioned each parts is by hose connection realization.

Owing to adopting said structure, simplify the step of platelet in Clinical practice, save time during platelet input Clinical practice, directly the platelet bag that platelet liquid is housed can be carried out clinical infusion, and utilize leukocyte depletion filter to filter, the design of multiple perforator can make multiple platelet bag provide platelet simultaneously, avoid same perforator repeatedly the plug of different platelet bag pollute.In addition, utilize the flushing to each platelet bag of normal saline, avoid hematoblastic residual waste.Filter screen in dropping funnel effectively filters blood clot, the impact on human body when preventing infusion, and the exhaust apparatus on bottle cork needle ensures the normal infusion of normal saline, prevents the generation of negative pressure.

In sum, owing to have employed technique scheme, the beneficial effects of the utility model are: a kind of platelet transfusion device of the present utility model, structure is simple, highly versatile, easy and simple to handle, reduce costs, the feature of use safety.
