Double-layer tearing type plasma bag

Abstract

The utility model relates to the technical field of medical instruments, in particular to a double-layer tearing type plasma bag which comprises a plasma bag body, a plasma inflow pipeline is arranged on one side of the plasma bag body, a protection bag is arranged on the outer side of the plasma bag body in a sleeved mode, a one-way inflation valve is arranged on the protection bag, and the protection bag and one side of the plasma bag body are sealed and thermally pressed together to form an inflation cavity. And protection bag tearable pull openings are formed in the three side edges of the protection bag except the side in which the protection bag and the plasma bag are sealed and subjected to hot pressing. In the transportation process, if the plasma bag is in contact with hard objects, the risk that the plasma bag is punctured and plasma is polluted and wasted is avoided due to buffering protection of the inflation cavity, and the plasma bag is exposed only when the surface of the protection bag of the double-layer tearing type plasma bag is in direct contact with the external environment and the protection bag is stripped from the plasma inflow pipeline during plasma feeding. The surface cleaning difficulty of the plasma bag before plasma feeding is reduced, and even cleaning is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a double-layer tearing type plasma bag. Background Art

[0002] Plasma bags are medical devices specifically used for collecting, storing and transfusing plasma. Plasma bags on the market are mainly composed of a plastic bag body and a plasma inflow pipe. There is a connected plasma inflow pipe on one side of the bag body, and the other three sides are sealed by melting. In the process of collecting, transporting and using plasma products, there are safety risks such as plasma bags falling and contacting contaminants, and hard objects scratching the plasma bags, causing plasma to flow out. Moreover, when plasma products are used for reproduction, the routine operation is to use a scalpel or surgical scissors to cut the plasma bag, collect enough plasma raw materials for production, and then use them in production. If the surface of the scalpel, surgical scissors or plasma bag is not thoroughly disinfected, it is easy to contaminate the plasma raw materials; in addition, the optimal cleanliness of the operating environment for plasma bag processing is Class D. There are a large number of suspended particles in the Class D environment. If the operator operates the plasma bag too frequently, these suspended particles can easily enter the product with the slurry production, and the risk of particulate contamination is unpredictable.

[0003] There is a tear-type plasma bag in the prior art (CN201610641605.8), which can avoid the risk of contamination caused by scratching the plasma bag with a scalpel or surgical scissors during routine operations, but it cannot avoid the risk of plasma leaking out due to scratches by hard objects during collection or transportation. Moreover, when the bag is taken or placed roughly during transportation, the tearable tearing head may be accidentally torn by the transport personnel, resulting in the risk of plasma waste caused by premature exposure of plasma to a contaminated environment. Utility Model Content

[0004] In view of the technical problem that the plasma bags provided by the prior art are not easy to protect plasma from contamination, the utility model provides a double-layer tearable plasma bag, the outer side of the plasma bag is provided with a protective bag made of the same material, and the inflation cavity between the plasma bag and the protective bag is filled with sterile inert gas, which plays a buffering and protective role for the plasma bag and reduces the risk of collision and damage of the plasma bag.

[0005] The technical solution of this utility model is as follows:

[0006] A double-layer tearable plasma bag comprises a plasma bag, a plasma inflow pipe is arranged on one side of the plasma bag, a protective bag is sleeved on the outside of the plasma bag, a one-way inflation valve is arranged on the protective bag, the protective bag and one side of the plasma bag are sealed and hot-pressed together to form an inflation cavity, and the three sides of the protective bag except the side sealed and hot-pressed with the plasma bag are all provided with tearable openings of the protective bag.

[0007] Furthermore, a tearable opening of the plasma bag is provided on the opposite side of the side where the plasma bag and the protective bag are sealed and heat-pressed.

[0008] Furthermore, an information identification chip is arranged on the tearable opening of the protective bag.

[0009] An information identification chip is set on the tearable opening of the protective bag, and the plasma information is quickly read and written through instrument scanning sensing. When the plasma outer bag is torn, the information chip is separated from the plasma bag, which is convenient for operators to collect the chip and trace the plasma information.

[0010] Furthermore, a quick sampling short tube is arranged on the plasma bag on the same side as the plasma inflow pipeline.

[0011] When a small amount of plasma needs to be collected for sampling and testing, it can be collected through a quick sampling short tube. After sampling, the quick sampling short tube is sealed by thermoplastic sealing to keep the plasma in the plasma bag in a sealed state.

[0012] Furthermore, before the plasma bag is filled with plasma, there is a vacuum state between the plasma bag and the protective bag.

[0013] Furthermore, after the plasma bag is filled with plasma, the plasma bag and the protective bag are not in contact except for one side where the plasma bag and the protective bag are sealed and heat-pressed.

[0014] The beneficial effect of the utility model is that when the plasma product is used for slurrying, the double-layer tearable plasma bag can better reduce the risk of plasma contamination:

[0015] (1) The double-layer tearable plasma bag provided by the utility model has a protective bag on the outside of the plasma bag, and the air-filled cavity between the plasma bag and the protective bag is filled with sterile inert gas. If the plasma bag contacts hard objects during transportation, the air-filled cavity provides buffering protection, thereby avoiding the problem of the plasma bag being punctured and the plasma being contaminated and wasted due to direct contact with hard objects.

[0016] (2) In the finished product of the double-layer tear-type plasma bag, only the surface of the protective bag is in direct contact with the external environment. When the plasma is injected, the protective bag is peeled off from the plasma inflow pipe and the plasma bag is exposed. This ensures that the surface of the plasma bag is clean and uncontaminated, reduces the difficulty of cleaning the surface of the plasma bag before use, and even eliminates the need for cleaning.

A plasma bag tearable opening 3 is arranged on the opposite side of the side where the plasma bag 1 and the protective bag 2 are sealed and hot-pressed. Before the plasma bag 1 is filled with plasma, there is a vacuum state between the plasma bag 1 and the protective bag 2. After the plasma bag 1 is filled with plasma, except for the side where the plasma bag 1 and the protective bag 2 are sealed and hot-pressed, the plasma bag 1 and the protective bag 2 are not in contact.

[0023] When collecting plasma, firstly, the plasma bag 1 is filled with plasma through the plasma inflow pipe 6, and then one side of the plasma inflow pipe 6 is thermoplastically sealed, and a certain amount of sterile inert gas is filled into the inflation cavity of the double-layer tearable plasma bag through the one-way inflation valve 8. When a small amount of plasma needs to be collected for sampling and testing, it can be collected through the quick sampling short tube 7. After sampling, the quick sampling short tube 7 is thermoplastically sealed to make the plasma in the plasma bag 1 in a sealed state.

[0024] When adding plasma, the protection bag 2 is cleaned and disinfected depending on specific requirements. The operator wearing gloves tears the tearable opening 4 of the protection bag to separate the protection bag 2 into two.
