Description

A new type of medicine plug for transfusion bag

technical field

The utility model relates to a medicine stopper in the medical field, in particular to a novel medicine stopper for an infusion bag.

Background technique

At present, the infusion bag in the medical field is usually provided with a medicine feeding plug and a medicine infusion plug, and the medicine infusion plug is used for connecting the infusion set and the infusion bag. The dosing plug is used to be pierced by a syringe to add other auxiliary drugs used in conjunction with the infusion into the infusion bag. In addition, a cork will also be set on the infusion bottle, which acts as a stopper for adding medicine or a stopper for infusion.

In the Chinese patent, a medical plug and its upper cover are disclosed, the patent number is CN2009202231823, and claim 8 discloses that "the upper end wall is provided with a folding handle, and the folding handle includes a folding part The root connected with the upper surface of the upper end wall is provided with a breakable groove inside the upper end wall, and the breakable groove is provided with a slope extending radially outward in the direction from top to bottom. The edge line of the inclined portion and the root of the turning handle constitutes a "breakable wall". Therefore, when the auxiliary drug is injected into the infusion bag with a syringe, the turning handle must be repeatedly pulled up and down, which makes the breakable wall fatigue. Damaged and broken, so that a hole can be opened on the top of the upper cover to facilitate the injection of auxiliary drugs into the infusion bag. It is very laborious to open the cover, and the rate of opening the cover is not very high. In addition, in this patent, from Figure 3 of this patent It can be seen that the upper cover and the lower part are fixedly connected together in the form of clamping, which leads to laborious transfer and low assembly efficiency.

At present, the rubber plugs in the medical plugs used in major hospitals are relatively thick, and sometimes it is difficult to pass the injection head of the syringe through the rubber plugs. Even sometimes when the injection head is inserted into the rubber stopper, because the outer diameter of the injection head is larger and the area of the rubber stopper is smaller, the rubber stopper is squeezed into the infusion bag by the injection head. The operation has brought a lot of trouble, so it is not promoted. In addition, the structure of the rubber plug is irregular, resulting in high mold costs.

Utility model content

The purpose of the utility model is to overcome the disadvantages of the prior art, and provide a new drug plug for infusion bags with simple structure, high assembly efficiency, labor-saving drug addition, low manufacturing cost and tight seal.

The purpose of this utility model is achieved through the following technical solutions: a novel infusion bag medication plug, which includes a loam cake, a rubber plug, a lower part and a rotating lid, the bottom of the loam cake is provided with a mold cavity, and the top of the loam cake A through hole I communicating with the cavity is provided, the inner wall of the cavity is provided with an internal thread, the outer wall of the top of the lower part is provided with an external thread, and the upper cover is fixed on the lower part through the internal thread and the external thread of the lower part. The top of the upper and lower parts is provided with a step hole, the top of the rubber plug is in the shape of a ball, the rubber plug is arranged in the step hole and the rubber plug is pressed between the upper cover and the lower part, the top of the rubber plug is provided with a communication For the through hole II of the through hole I, one end of the rotary cover is hinged on the top of the upper cover, the bottom of the rotary cover is provided with a rubber block, the rubber block is blocked in the through hole I, and the top of the rotary cover is provided with a pull ring.

The top of the upper cover is provided with rounded corners.

The utility model has the following advantages: (1) The spherical end of the rubber plug of the utility model has a small contact area with the bottom surface of the upper cover, which avoids interference and ensures that the rubber plug is tightly pressed against the upper cover and the lower part Between them, the sealability of the rubber plug is increased, and it has the characteristics of a tight seal. (2) The rubber plug of the utility model is a revolving body part with a simple structure, which reduces the manufacturing cost of the mold. (3) When using a syringe to add other auxiliary drugs into the infusion bag, you only need to pull the pull ring upward to rotate the rotating cover upward, and the rubber block is pulled out from the through hole I, and the through hole I is connected with the through hole II, and the Auxiliary drugs are added into the infusion bag without repeatedly turning the handle up and down, which has the characteristics of saving labor in adding drugs. (4) The upper cover and the lower part of the utility model are fixed by threaded connection, which does not need to be fixed in the form of clamping, and the assembly efficiency is very high.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described, and the protection scope of the utility model is not limited to the following:

As shown in Figure 1-4, a new type of drug stopper for infusion bag, it includes an upper cover 1, a rubber plug 2, a lower part 3 and a rotating cover 4, the bottom of the upper cover 1 is provided with a cavity 5, the upper cover The top of 1 is provided with a through hole I6 communicating with the cavity 5, the inner wall of the cavity 5 is provided with an internal thread 7, the outer wall of the top of the lower part 3 is provided with an external thread 8, and the upper cover 1 passes through the internal thread 7 It is connected and fixed on the lower part 3 with the external thread 8 of the lower part 3 . As shown in Figures 1, 3, and 4, a stepped hole 9 is provided on the top of the lower part 3, and the top of the rubber plug 2 is in the shape of a ball. The rubber plug 2 is set in the stepped hole 9 and the rubber plug 2 is pressed against it Between the cover 1 and the lower part 3, the contact area between the spherical end of the rubber plug 2 and the bottom surface of the upper cover 1 is small, which avoids interference and ensures that the rubber plug 2 is tightly pressed between the upper cover 1 and the lower part 3 , to increase the sealing performance of the rubber plug 2. As shown in Figure 1 or Figure 4, the top of the rubber plug 2 is provided with a through hole II10 communicating with the through hole I6, one end of the rotary cover 4 is hinged on the top of the upper cover 1, and the bottom of the rotary cover 4 is provided with a rubber block 11.
