Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a medical cleanser for controlling the flow of fluid within a tube by appropriately opening and closing a channel within the elastic tube.

Various types of medical clamps are used, and broadly speaking, there are those that have an opening for passing a tube through the clamp and those that do not. For tubes that do not have openings for attachment and detachment, in order to attach, for example, an indwelling needle, liquid bag, adapter, filter, etc. to both ends of the tube, clean the tube before assembling and attaching these parts. must be attached to the However, when assembling the other parts after attaching the clamp to the tube, there has been a problem that the clamp becomes an obstacle and takes time to assemble. Also, if you forgot to attach the clamp, it could not be used as a defective product. It was also inconvenient because it could not be removed from the tube. For this reason, a device was developed in which the clamp was provided with an opening for attaching and detaching it to the tube, eliminating the need to assemble and attach the clamp in advance. occurs often.

Therefore, the object of the present invention is to provide a medical clamp that can prevent the tube from falling off during use regardless of the tube diameter, without compromising the advantages of a clamp having an open portion that can be attached after assembly to the tube assembly.

What achieves the above object is a rigid plate-like member having a wide opening that accommodates a flexible elastic tube without blocking it, an intermediate portion that gradually narrows from there to guide the elastic tube, and a wide opening that accommodates the elastic tube without blocking it. In a medical treatment device, which has a continuous hole configured with a narrowed portion to be closed, and an opening portion that communicates with the wide opening of the continuous hole and is used for attaching to and detaching from the elastic tube, An elastic stopper whose tip extends from at least one free end side to the other free end side on the open part side and leaves a gap smaller than the outer diameter of the elastic tube is provided to prevent the clamp from falling off from the elastic tube. This is a medical cleanser.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the medical treatment according to the present invention will be described in detail as shown in the drawings.

As shown in FIG. 1, the cremmel of the present invention has a curved top 1, one side 2 following this, a bottom 3 extending approximately perpendicular to this, and a curved top 1 standing approximately perpendicular to this. A rigid plate-like member 6 consisting of the other side 5 which leaves an open part 4 for tube insertion between the narrow part 7 that crushes the tube and closes the flow path in the tube, and this thin groove-shaped A continuous hole 10 is formed with a middle part 8 that gradually becomes wider than a narrow part 7 of the tube, and a wide opening part 9 that opens a flow path in the tube.
In the illustrated example, a columnar elastic stopper 11 is installed on the free end of the other side 5 in the opening 4 formed between the opening 4 and the other side 5 so as to communicate with the wide opening 9 of the continuous hole 10. It is planted toward the free end of the curved top 1.

This elastic stopper 11 can be integrally molded with the plate member 6 in the shape of a column or plate, but it should be made sufficiently thin or thin so that the thickness when viewed from the side is 3/4 or less of the side parts 2 and 5. It is desirable to have elasticity in the insertion direction of the tube. Moreover, it may be made to have elasticity in a direction opposite to the insertion direction. In addition, the elastic stopper 11
It is desirable that the deformation occurs independently of the side portion 5. Also, as shown by the dotted line in FIG.
It is preferable to provide it at a height such that it comes into contact with the tip of the. This provides resistance when the tube tries to come off from the wide opening 9, as will be described later, and can prevent it from falling off. However, the stopper 11 is designed to leave at least a distance smaller than the diameter of the tube used, preferably 3/4 or less of the tube diameter, between the free end 13 of the curved top 1 and the free end 13 of the curved top 1. It can also be provided at a height such that it does not come into contact with it when it rotates. In this case, it is preferable to increase the thickness or thickness of the stopper 11 to increase its elastic force and increase the resistance to detachment of the tube. In addition, when the tube is installed and the tube is at the position of the curved apex 1 of the wide opening 9 as shown in FIG. It is desirable to provide 11.

Although it is convenient for use to provide the columnar or plate-shaped elastic stopper 11 on the free end of the other side 5 of the plate member 6 as shown in the figure, the free end 13 of the curved top part
Alternatively, they can be provided at the required length on each free end of the curved top 1 and the other side 5. In this case, two opposing elastic stoppers may overlap each other. Furthermore, the position where the opening is provided is not limited to the illustrated example. Further, a plurality of narrowing portions may be provided on the plate-like member.

Since it is preferable that the clamp of the present invention and the elastic stopper 11 be integrally molded from plastic, it is preferable to use a material that is hard to some extent and can impart elasticity to the stopper. Examples include polystyrene, Hard vinyl chloride, polycarbonate, polypropylene, polyester,
Examples include nylon, MBS resin, ABS resin, etc., but other resins may also be used.

Next, to briefly explain the usage of the medical cremen of the present invention explained above, tube 14
When passing the tube 14 through the clamp, as shown in FIG. insert. tube 14
When the stopper 11 is pushed in, the stopper 11 returns to its original position due to elasticity, the tube 14 rests in the wide opening 9 of the continuous hole 10, and the flow path of the tube is opened (see Fig. 3b). When attempting to block the flow path of the tube 14, the tube 14 is forcibly moved to the narrowed portion 7 through the intermediate portion 8 of the continuous hole 10, and the tube 14 is crushed as before. In order to concentrate the tightening force and ensure closure, it is desirable that the thickness of the member of the narrowed part 7 is thinner than the thickness of the side parts 2 and 5 when viewed from the side. During use, if the tube 14 attempts to detach from the opening 4 due to various external forces acting on the tube and clamp (see Figure 3c), the elastic repulsion force of the stopper 11 itself may cause the stopper 11 to move away from the curved top. By coming into contact with the free end 13 of 1, it is prevented from coming off. Further, by strongly pulling the tube from the open portion 4 in a direction opposite to the direction in which the tube is pushed in, the stopper 11 is elastically deformed outward and the slide clamp can be removed from the tube.

As is clear from the above explanation, by using the medical cleanser of the present invention, indwelling needles,
In the manufacturing and assembly process in which liquid bags, adapters, filters, etc. are attached to both ends of the tube, there is no restriction on when to attach slide clamps, and there is no possibility of defective products due to omission of attachment. Moreover, the slide clamp does not become an obstacle and take time to assemble. Furthermore, the problem of the slide clamp falling off or being lost from the tube during use of the product is solved, and the slide clamp can be easily removed when unnecessary, which is very beneficial in terms of use.
