Description

A collection device for testing plasma in a rigid plasma bottle

technical field

The utility model relates to a device for sampling plasma in a plasma bottle collected from a human body for the purpose of testing, specifically a collection device for testing plasma in a rigid plasma bottle, and belongs to the technical field of medical devices.

Background technique

When the plasmapheresis machine collects plasma, the sterile air in the separation cup enters the cup along with the blood, and the air in the cup is discharged into the plasma bottle. Since the plasma bottle is solid, the air in the plasma bottle goes with the The air filter of the plasma bottle is discharged out of the bottle, so as to ensure that there is no resistance for the plasma to enter the plasma bottle. In the separation cup, in order to prevent the plasma bottle from generating negative pressure, the air outside the plasma bottle is replenished into the plasma bottle through the air filter of the plasma bottle.

See Figure 1. After the plasma collection is completed, the plasma needs to be sampled and sent for inspection. The nurse removes the plasma bottle from the plasmapheresis machine and places it horizontally on the table. The plasma in the bottle will flow to the air filter through the sampling pipeline. The purpose is to remove the air in the sampling line 6 (at this time, the air filter membrane of filter 2 may be wetted), and then pass through the blood cell sampling puncturer of the plasma bottle to collect For plasma samples, when the sampling tube is inserted into the blood cell sampling puncturer, the plasma in the bottle enters the sampling tube along with the blood cell sampling puncturer. During this process, since the air filter membrane of the filter 2 may be wetted by the plasma, after the sampling is completed, the residual plasma in the sampling line 6 cannot flow back into the plasma bottle 1, resulting in a waste of this period of plasma , The amount of plasma collected and used by hospitals and plasma collection companies is very large, and the accumulation of small amounts becomes more. This waste phenomenon has brought great troubles to hospitals and plasma collection companies.

The solutions in the prior art focus on the filter density performance of the air filter membrane 202 on the research filter 2, but if the filter density is too low, the plasma liquid will leak at the air filter, and the filter density is too high. Then there will be poor air permeability and poor exhaust, so it is a very difficult thing to develop an air filter membrane with suitable filter density performance that can solve this technical problem.

Utility model content

The technical problem to be solved by the utility model is: in the collection process of rigid plasma bottle inspection plasma, when the sampling is completed, the residual plasma in the sampling pipeline cannot flow back into the plasma bottle, resulting in the waste of this section of plasma. The phenomenon has brought great troubles to hospitals and plasma collection companies.

The utility model takes the following technical solutions:

A method for collecting plasma in a rigid plasma bottle for testing, comprising the following steps:

A) Lie down the rigid plasma bottle that has completed the blood collection, the plasma flows out from the sampling line 6, and is extracted through the needle tube 401 in the protective cover 4; the filter 2 acts as a ventilating liquid barrier, and the filter membrane 202 in it may be sticky blood;

B) Insert an air compression device into the air vent of the filter 2, fill the sampling line 6 with air, and return the residual plasma in the sampling line 6 to the plasma bottle.

Further, after step A), the plasma bottle is now erected, and then step B) is implemented.

A collection device of the above collection method is characterized in that it includes an air compression device and a filter 2, and the air outlet of the air compression device is in sealing fit with the air vent of the filter 2.

Further, the air compression device is an injection syringe.

Further, the air compression device is a sphygmomanometer ball.

Further, the air compression device is an air cylinder.

The beneficial effects of the utility model are:

1) The residual plasma in the sampling line can be returned to the plasma bottle, saving precious blood resources.

2) Solve the long-term troubles and technical problems of hospitals and plasma collection companies.
