Cross-contamination prevention sealing kit for pharmacological tissue homogenizer

Abstract

This utility model discloses a cross-contamination prevention sealing kit for a pharmacological tissue grinder, relating to the technical field of pharmacological experimental equipment. The sealing cover has an annular groove on its inner wall, with several through-holes at the bottom of the groove. A sealing gasket is fastened inside the annular groove, and several elastic positioning posts are fixedly connected to the lower end of the sealing gasket. The lower ends of the elastic positioning posts pass through the through-holes and extend to the outside of the sealing cover. Several first threaded holes arranged in a circular array are provided on the inner wall of the side of the sealing cover. The beneficial effects of this utility model are: by setting the sealing cover and the annular groove, the sealing gasket can be quickly installed, increasing the overall sealing performance. Furthermore, by setting a fixing ring on the outside of the sealing gasket in conjunction with the threaded holes and screws, the overall installation stability of the sealing gasket is increased, preventing it from detaching during use. Additionally, when the sealing gasket needs to be replaced later, pushing the elastic positioning posts allows for quick and easy removal of the sealing gasket, increasing replacement efficiency.

Description

Technical Field

[0001] This utility model relates to the field of pharmacological experimental equipment technology, specifically to a cross-contamination prevention sealing kit for a pharmacological tissue grinder. Background Technology

[0002] In pharmacological experiments, tissue homogenizers are used to grind biological tissues into homogenates for subsequent analysis. However, the sealing kits of traditional pharmacological tissue homogenizers have shortcomings in the connection between the sealing ring and the sealing cap. Common connection methods, such as simple embedding or pasting, do not provide a good seal. During the grinding process, aerosols and liquids generated by the sample can easily leak from the connection between the sealing ring and the sealing cap, leading to cross-contamination between different samples. At the same time, it is difficult to quickly replace the sealing ring after it ages or becomes contaminated, and the sealing ring or sealing cap may be damaged during cleaning due to overly tight connections. Utility Model Content

[0003] The purpose of this invention is to provide a cross-contamination prevention sealing kit for a pharmacological tissue homogenizer, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cross-contamination prevention sealing kit for a pharmacological tissue grinder, comprising a sealing cover, an annular groove on the inner wall of the sealing cover, several through holes at the bottom of the annular groove, and a sealing gasket fastened inside the annular groove, with several elastic positioning posts fixedly connected to the lower end of the sealing gasket, the lower ends of the elastic positioning posts passing through the through holes and extending to the outside of the sealing cover.

[0005] Preferably, the inner wall of the side of the sealing cover has a plurality of first threaded holes arranged in a circular array, the upper end of the sealing gasket is fixedly connected to a fixing ring, and the fixing ring and the corresponding positions of the first threaded holes are each provided with a second threaded hole, and the first threaded holes and the second threaded holes are both threadedly connected to a screw.

[0006] Preferably, a plurality of the through-holes are arranged in a circular array at the bottom of the annular groove.

[0007] Preferably, a one-way valve is fixedly connected to the middle of the sealing cover.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting a sealing cap and annular groove, the sealing gasket can be installed quickly, increasing the overall sealing performance. Moreover, by setting a fixing ring on the outside of the sealing gasket in conjunction with a threaded hole and a screw, the overall installation stability of the sealing gasket is increased, preventing it from coming off during use. At the same time, when the sealing gasket needs to be replaced later, pushing the elastic positioning pin can easily and quickly push the sealing gasket out, increasing the efficiency of later replacement.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a cross-contamination prevention sealing kit for a pharmacological tissue grinder, comprising a sealing cover 1, characterized in that: an annular groove 2 is formed on the inner wall of the sealing cover 1, and several through-holes 3 are formed at the bottom of the annular groove 2, and a sealing gasket 4 is fastened inside the annular groove 2; several elastic positioning posts 5 are fixedly connected to the lower end of the sealing gasket 4, and the lower end of the elastic positioning posts 5 passes through the through-holes 3 and extends to the outside of the sealing cover 1; several first threaded holes 6 are formed in a circular array on the inner wall of the side of the sealing cover 1; a fixing ring 7 is fixedly connected to the upper end of the sealing gasket 4; second threaded holes 8 are formed through the corresponding positions of the fixing ring 7 and the first threaded holes 6; the first threaded holes 6 and the second threaded holes 8 are both threadedly connected to a screw 9; several through-holes 3 are arranged in a circular array at the bottom of the annular groove 2; and a one-way valve 10 is fixedly connected to the middle of the sealing cover 1.

[0017] Specifically, when using this utility model, when it is necessary to install the sealing gasket 4 inside the sealing cover 1, first fasten the sealing gasket 4 into the annular groove 2 inside the sealing cover 1. At this time, the sealing gasket 4 will drive the elastic positioning post 5 to move through the upper end of the through hole 3 to the outside of the sealing cover 1. At the same time, after the sealing gasket 4 is stably installed inside the sealing cover 1, the fixing ring 7 at the upper end of the sealing gasket 4 will enter the inside of the sealing cover 1 simultaneously. Then, the screw 9 passes through the first threaded hole 6 and is threaded into the second threaded hole 8. At this time, the overall sealing performance of the sealing gasket 4 is increased to prevent cross-contamination from grinding.
