Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present utility model. It will be apparent, however, to one skilled in the art that the utility model may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the utility model.

In order to provide a thorough understanding of the present utility model, detailed steps and detailed structures will be presented in the following description in order to explain the technical solution of the present utility model. Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

Referring to fig. 1, the utility model provides a sterile plug 1 for rapidly taking large infusion in an infusion bottle, wherein the sterile plug 1 is in an integrally formed bullet shape, the front end of the sterile plug 1 is a closed pointed end, the rear end of the sterile plug 1 is a liquid outlet pipe, an anti-slip convex point or convex ring 2 is arranged on the outer diameter of the liquid outlet pipe, a circle of inwards concave grooves 3 are arranged at the outer diameter of the sterile plug 1 close to the rear end, and small holes 4 with the aperture of 2-3mm are densely distributed at the pointed end of the sterile plug 1.

In one embodiment the maximum diameter of the tail of the tip end is the same as the diameter of the outlet tube, as shown in fig. 1. In another embodiment, as shown in fig. 2, the maximum diameter of the tail part of the tip end is smaller than the diameter of the liquid outlet pipe, and the diameter of the sterile plug 1 adopts a sectional design, so that on one hand, the middle groove is ensured to be in the rubber plug, and on the other hand, the outer diameter of the liquid outlet pipe at the rear end is larger than the diameter of the tail part of the tip end, and a step is formed at one side of the groove, which is close to the liquid outlet pipe, so that the outer end face of the rubber plug can be propped against, and the tightness is improved. It should be noted that, the rubber plug of the large infusion bottle is usually made of rubber, the rubber has certain elasticity, and when the sterile plug 1 is inserted into the groove of the rubber plug to be matched with the rubber plug, the rubber plug can form sealing fit with the groove 3 under the action of the elasticity of the rubber plug, so that the tightness is ensured.

In the present utility model, the aseptic plug 1 may be classified as a disposable plug or a plug which is reused after being sterilized. If the aseptic plug 1 is a disposable plug, the aseptic plug 1 is integrally formed of polypropylene for cost reduction. The sterile plug 1 can also be made of 304/306 stainless steel, and can be reused after disinfection, so that the use cost is reduced.

In an alternative embodiment, the groove 3 needs to have a certain depth, and the sterile plug 1 can be firmly clamped on the plug through the groove 3 after being inserted into the plug, meanwhile, good tightness is ensured, and a large amount of liquid in the bottle can be quickly obtained from the opening end of the plug by directly extruding the bottle body or pouring. Preferably, the depth of the groove 3 is 3-5mm.

In an alternative embodiment, two parallel convex rings 2 are arranged on the outer diameter of the liquid outlet pipe, and when the liquid outlet pipe is inserted, the liquid outlet pipe can play a role in preventing the liquid outlet pipe from sliding down through the two slightly convex rings 2.

The operation method of the utility model is as follows:

1) The bottle mouth sealing cover of the infusion bottle is pulled off first, and the rubber plug in the bottle mouth sealing cover is exposed.

2) The corresponding procedure is then performed depending on whether the sterile plug 1 is a disposable plug or not.

Disposable plug: taking a plug with a package, holding the back end by one hand, tearing half of the package from the tip by one hand, and slightly forcefully inserting the back end with the package into the rubber plug until reaching the narrow neck bayonet.

Reusable 304 plug: the sterilized plug is held at the rear end by one hand, and the half of the tinfoil covered by the plug is torn off by the same sterile forceps by the other hand, and then the rear end with the tinfoil is held by the other hand and is forcefully inserted into the rubber plug until reaching the narrow neck bayonet.

3) When the wound is washed, the bottle mouth is inclined, the bottle body is slightly extruded, and the wound is repeatedly washed around the wound surface until dirt is washed off, and then the wound can be further treated.

4) In the processing of tissue samples, often stained specimens, a large volume of a suitable liquid is required to be rinsed clean.

The brine bottle with the plug can be directly poured and repeatedly washed until the blood is cleaned.

5) When the cells are collected after the medium-large scale culture of the cells, the cell suspension is centrifuged firstly, after the culture medium is removed, the saline bottle with the plug is directly poured into the centrifuge tube to resuspend the bottom cells of the tube, and then the cells are centrifuged again, so that the purpose of cleaning the cells is achieved.

The preferred embodiments of the present utility model have been described above. It is to be understood that the utility model is not limited to the specific embodiments described above, wherein devices and structures not described in detail are to be understood as being implemented in a manner common in the art; any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model or modifications to equivalent embodiments without departing from the scope of the technical solution of the present utility model, using the methods and technical contents disclosed above, without affecting the essential content of the present utility model.
