Description

A new type of blood transfusion device

technical field

The utility model relates to the technical field of medical appliances, in particular to a novel blood transfusion device.

Background technique

At present, when a large amount of blood transfusion is needed in hospitals, such as the delivery of platelets, plasma and cryoprecipitate, in order to prevent hemolysis or coagulation between the blood of different blood donors and reduce blood waste, after a bag of blood transfusion is completed, it is necessary to use Rinse the blood bag with normal saline. The amount of normal saline is generally 30ml. In this step, the normal saline needs to be injected into the blood bag and shaken, and then the residual blood and normal saline in the blood bag are shaken and then input into the patient's body. To achieve the effect of flushing the blood bag, reduce waste.

At present, there are generally two methods for medical staff to inject physiological saline into the blood bag: the first method is to use a single-line blood transfusion device. The disadvantage of this method is that because the syringe can only inject a small amount of physiological saline at a time, it is necessary to repeatedly puncture the blood bag with the syringe to inject a certain amount of physiological saline into the blood bag. This method is very troublesome, and It is easy to contaminate syringe needles and blood, increasing the chance of infection for the patient. The second method is to use a Y-type blood transfusion device for blood transfusion. The Y-type blood transfusion tube has two infusion branches and an infusion main pipe. The two infusion branches are respectively connected to the blood bag and the normal saline bag. Conditioning allows a small amount of saline to flow from the saline bag into the blood bag. In this case, the flow of saline is very slow and the saline takes a long time to reach the blood bag. This method is used in the ICU, surgery It takes a long time to rescue patients with hemorrhagic shock, which is not conducive to rescue.

Utility model content

In view of the above problems existing in the prior art, the purpose of the present invention is to provide a new type of blood transfusion device, which is simple and convenient to operate and can quickly transport a small amount of physiological saline into the blood bag for cleaning the blood bag, while reducing the the chance of blood contamination.

In order to achieve the above purpose, the technical solution of the present utility model is: a new type of blood transfusion device, comprising a Y-shaped blood transfusion device, the Y-shaped blood transfusion device includes a main infusion tube, a Y-shaped connector connected to one end of the main infusion tube, and a connection the first infusion branch pipe and the second infusion branch pipe on the Y-type joint; the first infusion branch pipe and the second infusion branch pipe are respectively connected with a first three-way valve and a second three-way valve, the The first ports of the first three-way valve and the second three-way valve are respectively connected with the first infusion branch pipe and the second infusion branch pipe, and the first three-way valve and the second three-way valve are connected with each other. The second ports are respectively connected with a first puncture needle and a second puncture needle, and the third ports of the first three-way valve and the second three-way valve are respectively connected with a negative pressure ball assembly.

As a specific embodiment, the negative pressure ball assembly includes a negative pressure ball, a first negative pressure tube and a second negative pressure tube, and one end of the first negative pressure tube is connected to the first and third negative pressure tubes. The third port of the through valve is connected, the other end is connected with the negative pressure ball, one end of the second negative pressure tube is connected with the third port of the second three-way valve, and the other end is connected with the negative pressure ball connect.

Further, a ventilation hole is provided on the outer surface of the negative pressure ball and a plug matched with the ventilation hole is connected.

As a specific embodiment, both the first three-way valve and the second three-way valve are T-shaped.

The beneficial effects of the present utility model are:

The utility model adds a negative pressure ball on the basis of the Y-type blood transfusion device, through the negative pressure principle of the negative pressure ball, a small amount of physiological saline can quickly flow from the physiological saline bag into the negative pressure ball, and by using The acupressure method flattens the negative pressure ball to form a thrust, so that the physiological saline can be quickly flowed from the negative pressure ball to the blood bag for cleaning the blood bag. This process saves a lot of time and wins valuable for medical staff to treat patients time, and because it does not require a syringe to be inserted directly into the blood bag to deliver saline, it reduces the chance of blood contamination.
