Description

Technical Field

[0001] The utility model relates to the technical field of reaction cups, in particular to a pollution-proof reaction cup for in vitro diagnostic reagent detection. Background Art

[0002] The reaction cup for in vitro diagnostic reagent testing is a container designed to hold samples, reagents and promote chemical or biological reactions between them. It is often used for various chemical reactions and biological testing activities.

[0003] During the reaction cup detection process, it is often necessary to add additives to the reaction bottle to mix with the reagents. During this process, the top of the reaction cup is in an open state. At this time, external dust and impurities can easily enter the reaction cup to contaminate the sample and affect the test results. At the same time, when adding reagents and additives and taking and placing samples in the reaction cup, the reaction cup is prone to sputtering, thereby causing pollution to the surrounding environment and making it difficult to meet the use requirements. Utility Model Content

[0004] The purpose of the utility model is to provide a contamination-resistant reaction cup for in vitro diagnostic reagent detection, which has the advantages of being able to improve the accuracy of detection results, reduce the risk of sample contamination, and reduce the occurrence of sputtering to avoid pollution of the surrounding environment, thereby solving the problem that when the current reaction cup is used, the sample in the reaction cup is easily contaminated.

[0005] To achieve the above object, the utility model provides the following technical solutions: a contamination-proof reaction cup for in vitro diagnostic reagent detection, comprising a cup body, a cup cover is arranged above the cup body, and the cup body and the cup cover are threadedly connected;

[0006] The inner wall of the cup body is provided with a raised portion, a buffer pad is fixed at the bottom of the inner wall of the cup body, an anti-overflow groove is provided above the inner wall of the cup body, a guide plate is fixed on the inner wall of the cup cover, and a liquid adding pipe is connected to the top of the cup cover;

[0007] An isolation membrane is fixed on the surface of the guide plate, a puncture cone is slidably penetrated on the surface of the cup cover, a plurality of limit plates are fixed on the inner wall of the cup cover, a limit groove is opened on the surface of the puncture cone for use with the limit plate, and a closing cover is threadedly connected to the surface of the liquid adding tube.

[0008] As a preferred anti-contamination reaction cup for in vitro diagnostic reagent detection of the utility model, a connecting shell is fixed on the top of the cup cover, a protective shell is threadedly connected to the surface of the connecting shell, and the puncture cone slides through the connecting shell.

[0009] As a preferred anti-pollution reaction cup for in vitro diagnostic reagent detection of the utility model, a top plate is fixed on the top of the cup body, and a sealing ring is fixed on the bottom of the guide plate.

[0010] As a preferred embodiment of the anti-contamination reaction cup for in vitro diagnostic reagent detection of the utility model, the limiting plates are made of polyethylene, and the number of the limiting plates is four.

[0011] As a preferred anti-pollution reaction cup for in vitro diagnostic reagent detection of the utility model, the cup body and the cup cover are both made of polypropylene.

[0012] As a preferred embodiment of the anti-pollution reaction cup for in vitro diagnostic reagent detection of the utility model, the buffer pad is made of medical silica gel.

[0013] As a preferred embodiment of the anti-pollution reaction cup for in vitro diagnostic reagent detection of the utility model, the isolation membrane is made of polyvinylidene fluoride.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. In the utility model, when reagents or samples are added to the cup body, since the cup mouth of the cup body is narrower than the middle and lower parts of the cup body, the reduced cup mouth can disperse the impact force of the liquid reagent at the moment of entering the cup due to the increased cross-sectional area, thereby reducing splashing, and the liquid added to the cup body can directly impact the surface of the buffer pad, which can absorb part of the impact energy and reduce the occurrence of splashing, and the dispersion grooves on the surface of the buffer pad can disperse the flow direction of the liquid, so that it diffuses to all sides after hitting the bottom, instead of rebounding upward. When the liquid approaches the highest point of the cup mouth, the liquid will temporarily stay in the groove, giving the operator more time to adjust the pouring angle of the cup body and the adding speed, and the wavy design of the raised part can disperse the impact force of the liquid when it flows out, reducing the possibility of splashing, and the additives can be added to the inside of the cup cover through the liquid adding tube, and the guide plate on the inclined surface can guide the additives to slow down the speed and strength of the liquid outflow and reduce the risk of splashing.

[0016] 2. The additives added by the utility model through the liquid adding tube can be accumulated above the isolation membrane, thereby directly avoiding the top of the cup body being in an open state when the additives are added, reducing the entry of dust and external impurities, and after the additives are added, the closing cover can be twisted into the surface of the liquid adding tube to seal the top of the cup cover, so that the reaction cup can add additives to the cup body when testing is required. When additives need to be added, the puncture cone is pressed downward to deform the limit plate and disengage from the limit groove, so that the puncture cone can move downward normally, and then puncture the isolation membrane, so that the additives on the isolation membrane surface flow directly into the cup body. In this process, the additives and the cup body will not be affected and contaminated by external dust or other impurities, thereby improving the accuracy of the test results.

DETAILED DESCRIPTION

[0022] See also Figure 1-4 , a contamination-proof reaction cup for in vitro diagnostic reagent detection, comprising a cup body 1, a cup cover 2 is arranged above the cup body 1, and the cup body 1 and the cup cover 2 are threadedly connected;

[0023] The cup body 1 and the cup cover 2 can be combined, and after the cup cover 2 is twisted into the surface of the cup body 1, the reaction cup can have a basic sealing effect.

[0024] The inner wall of the cup body 1 is provided with a raised portion 4, which is arranged in a corrugated structure. The middle and lower parts of the cup body 1 are wider than the top of the cup body 1. A buffer pad 5 is fixed to the bottom of the inner wall of the cup body 1, and a plurality of dispersion grooves are opened on the surface of the buffer pad 5. An anti-overflow groove 3 is arranged above the inner wall of the cup body 1. A guide plate 8 is fixed to the inner wall of the cup cover 2, and the guide plate 8 is arranged in a funnel shape. The top of the cup cover 2 is connected to a liquid adding pipe 10;

[0025] When reagents or samples are added to the cup body 1, since the cup mouth of the cup body 1 is narrower than the middle and lower parts of the cup body 1, the reduced cup mouth can disperse the impact force of the liquid reagent at the moment of entering the cup due to the increase in cross-sectional area, thereby reducing splashing. The liquid added to the cup body 1 can directly impact the surface of the buffer pad 5, and the buffer pad 5 can absorb part of the impact energy to reduce the occurrence of splashing. The dispersion grooves on the surface of the buffer pad 5 can disperse the flow direction of the liquid, so that it diffuses to the surroundings after hitting the bottom instead of rebounding upward. When the liquid approaches the highest point of the cup mouth, the liquid will temporarily stay in the groove, giving the operator more time to adjust the pouring angle and adding speed of the cup body 1, and the wavy design of the raised portion 4 can disperse the impact force of the liquid when it flows out, reducing the possibility of splashing. Additives can be added to the inside of the cup cover 2 through the liquid adding tube 10, and the guide plate 8 on the inclined surface can guide the additives to slow down the speed and force of the liquid outflow and reduce the risk of splashing.

[0026] An isolation membrane 9 is fixed on the surface of the guide plate 8, a puncture cone 6 is slidably penetrated on the surface of the cup cover 2, a plurality of limit plates 7 are fixed on the inner wall of the cup cover 2, a limit groove for cooperating with the limit plate 7 is opened on the surface of the puncture cone 6, and a closing cover 11 is threadedly connected to the surface of the liquid adding tube 10;

[0027] The additives added through the liquid adding tube 10 can be accumulated above the isolation membrane 9, thereby directly avoiding the top of the cup body 1 being in an open state when the additives are added, reducing the entry of dust and external impurities, and after the additives are added, the closing cover 11 is twisted into the surface of the liquid adding tube 10 to seal the top of the cup cover 2, so that the reaction cup can add additives to the cup body 1 when testing is required. When additives need to be added, the puncture cone 6 is pressed downward to deform the limiting plate 7 and disengage from the limiting groove, so that the puncture cone 6 can move downward normally, and then pierce the isolation membrane 9, so that the additives on the surface of the isolation membrane 9 flow directly into the cup body 1. In this process, the additives and the cup body 1 will not be affected and contaminated by external dust or other impurities, thereby improving the accuracy of the test results.

[0028] Furthermore, a connecting shell 14 is fixed on the top of the cup cover 2, a protective shell 15 is threadedly connected to the surface of the connecting shell 14, and the puncture cone 6 slides through the connecting shell 14;

[0029] The protective shell 15 can be twisted into the surface of the connecting shell 14, so that the protective shell 15 can protect the puncture cone 6 and prevent the operator from touching the puncture cone 6 when no detection is required.

[0030] Furthermore, a top plate 12 is fixed on the top of the cup body 1, and a sealing ring 13 is fixed on the bottom of the guide plate 8;

[0031] After the cup body 1 and the cup cover 2 are connected, the top plate 12 will squeeze the sealing ring 13, thereby improving the sealing effect after the cup body 1 and the cup cover 2 are connected.

[0032] Furthermore, the limiting plates 7 are made of polyethylene, and the number of the limiting plates 7 is four;

[0033] The limiting plate 7 made of polyethylene material enables the puncture cone 6 to be deformed, and the provision of multiple limiting plates 7 improves the limiting effect of the puncture cone 6.

[0034] Furthermore, the cup body 1 and the cup cover 2 are both made of polypropylene;

[0035] Polypropylene is resistant to high temperatures, has good chemical stability and good biocompatibility. It will not react with samples or reagents, nor will it adsorb components in the samples, causing deviations in test results.

[0036] Furthermore, the cushion 5 is made of medical silicone;

[0037] Medical silicone has stable chemical properties and will not react with most biological samples and chemical reagents. At the same time, it has good elasticity and recovery, can absorb a certain amount of impact force and reduce the sputtering effect.

[0038] Furthermore, the isolation membrane 9 is made of polyvinylidene fluoride;

[0039] Polyvinylidene fluoride has good chemical stability and biocompatibility, is heat-resistant and easy to process, and can be well applied to the isolation membrane 9 .

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
