Abstract
The utility model relates to a sealing joint for a gas-liquid mixing agent bag. The joint comprises a heat sealing head, an O-shaped seal ring, an elastic plunger piston, a first stop block and a second stop block, wherein the heat sealing head is bonded with an empty agent bag in a heat sealing manner; the first stop block and the second stop block are located at two ends of the heat sealing head; the O-shaped seal ring and the elastic plunger piston are mounted between the first stop block and the second stop block; the first stop block locates the O-shaped seal ring; and the second stop block locates the elastic plunger piston. According to the sealing joint for the gas-liquid mixing agent bag, the empty agent bag is pumped into a vacuum state firstly, then a gas-liquid mixing agent is filled into the agent bag, and after filling, the sealing joint can be sealed automatically, so that a liquid in the bag is guaranteed to be isolated from outside air.
Description
Technical field
The utility model relates to sealing adaptor, especially has the sealing adaptor of the gas-liquid mixed reagent bag of self-sealing function.
Background technology
Gas content in gas-liquid mixed reagent bag has strict demand, can not entrained air while particularly pouring into.For example mainly there are following 2 deficiencies in the existing sealing adaptor of blood gas analyzer reagent bag.
The one, during perfusion, be deaeration, adopt the method for leading to protection gas or sealing again after the reagent bag is filled, equipment complexity, operation inconvenience, and easy residual air; The 2nd, can only disposable extracting liquid, after joint punctured, its sealing was namely destroyed, did not support to get the liquid pin and repeatedly plugged.
Summary of the invention
The purpose of this utility model be to provide a kind of can perfusion or extract gas-liquid mixed reagent, and in perfusion or extract after completing the sealing adaptor that can realize self-sealing function.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of sealing adaptor for gas-liquid mixed reagent bag, by heat-sealing head, O RunddichtringO, resilient plunger, the first block and the second block form;
Heat-sealing head and the heat-sealing of empty reagent bag are bonding, and the first block and the second block are positioned at the heat-sealing head two ends, between the first block and the second block, O RunddichtringO and resilient plunger are housed, and the first block is O RunddichtringO location, and the second block is the resilient plunger location.
Resilient plunger and O RunddichtringO are in the compression deformation state all the time, and resilient plunger top and the laminating of heat-sealing head interior step place form sealing, and resilient plunger sidewall and heat-sealing head inwall leave gap.
Described resilient plunger has suitable elasticity, makes it after the reagent bag vacuumizes, and can not backed down by atmospheric pressure.
Described heat-sealing head material is polypropylene.
After perfusion (sampling) pin inserted, its outer wall and O RunddichtringO formed sealing, and resilient plunger is separated with heat-sealing head, at this moment, and the function that can realize pouring into reagent or extract reagent.When resilient plunger, when pin does not insert perfusion or sampling, with heat-sealing head, form sealing.When the O RunddichtringO inserts perfusion or sampling at pin, with its outer wall, form sealing.Described resilient plunger and heat-sealing head are realized the function of similar retaining valve, therefore also can be realized by other elastomeric element.
The beneficial effects of the utility model are, can realize the state that first empty reagent bag is evacuated, then to perfusion gas-liquid mix reagent in the reagent bag, after perfusion completed, sealing adaptor got final product self sealss, guarantee solution in bag and extraneous air insulated.Seal joint structure of the present utility model is simple, process, and cost is lower.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment three-dimensional exploded view;
Fig. 2 is the utility model embodiment cut-open view;
Fig. 3 is the utility model embodiment perfusion state schematic diagram;
Fig. 4 is the utility model embodiment view of taking a sample.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, the utility model is take the sealing adaptor for blood gas analyzer reagent bag as example, and the sealing joint is comprised of heat-sealing head 1, resilient plunger 2, O RunddichtringO 3, the first block 4 and the second block 5.
Heat-sealing head 1 two ends are equipped with between the first block 4 and the second block 5, the first blocks 4 and the second block 5 and are equipped with O RunddichtringO 3 and resilient plunger 2, the first blocks 4 is O RunddichtringO 3 location, and the second block 5 be that resilient plunger 2 is located.
By shown in Figure 2, resilient plunger 2 is in the compression deformation state all the time with O RunddichtringO 3, and resilient plunger 2 tops and heat-sealing head 1 interior step place laminating form sealing, and resilient plunger 2 sidewalls and heat-sealing head 1 inwall leave gap.
By Fig. 3 and shown in Figure 4, after perfusion (sampling) pin 6 inserted, its outer wall and O RunddichtringO 3 formed sealing, and resilient plunger 2 tops are separated with heat-sealing head 1, at this moment, and the function that can realize pouring into reagent (Fig. 3) or extract reagent (Fig. 4).
For reducing costs, each part is the mold injection casting.Wherein the heat-sealing head material is polypropylene, and is bonding with the aluminum-plastic composite membrane heat-sealing of empty reagent bag.The resilient plunger material is natural rubber.
Claims (2)
1. the sealing adaptor for gas-liquid mixed reagent bag, is characterized in that, by heat-sealing head, O RunddichtringO, resilient plunger, the first block and the second block form;
Heat-sealing head and the heat-sealing of empty reagent bag are bonding, and the first block and the second block are positioned at the heat-sealing head two ends, between the first block and the second block, O RunddichtringO and resilient plunger are housed, and the first block is O RunddichtringO location, and the second block is the resilient plunger location.
2. a kind of sealing adaptor for gas-liquid mixed reagent bag according to claim 1, it is characterized in that, described resilient plunger and O RunddichtringO are in the compression deformation state all the time, resilient plunger top and the laminating of heat-sealing head interior step place form sealing, and resilient plunger sidewall and heat-sealing head inwall leave gap.
