Description

A medicinal plug with a rotating cap

technical field

The utility model relates to a medicinal plug in the medical field, in particular to a medicinal plug with a rotating cover.

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 medicine plug with a rotating cover with simple structure, high assembly efficiency, labor-saving dosing, low manufacturing cost and tight sealing.

The purpose of this utility model is achieved through the following technical solutions: a medicine plug with a rotating cover, which includes an upper cover, a rubber plug, a lower part and a rotating cover, and the top surface of the upper cover is provided with a through hole I , the bottom surface of the upper cover is provided with two tapered columns, the two tapered columns are symmetrically arranged on both sides of the through hole I, the top of the lower part is provided with a step hole, and the top of the lower part is located on the step There are tapered holes on both sides of the hole. The upper cover is respectively inserted into the two tapered holes and fixed on the lower part through two tapered columns. The top of the rubber plug is in the shape of a ball, and the rubber plug is set 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 through hole II communicating with the through hole I, one end of the rotating cover is hinged on the top of the upper cover, and the rotating cover The bottom is provided with a rubber block, and the rubber block is blocked in the through hole 1, and the top of the rotating cover is provided with a pull ring.

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

The through hole I is arranged in the middle of the upper cover.

The diameter of the through hole I is larger than that of the through hole II.

The utility model has the following advantages: (1) The two tapered columns of the upper cover are respectively inserted into the tapered holes, so that the upper cover can be quickly fixed on the lower part without clamping, and the assembly efficiency is very high . (2) The contact area between the spherical end of the rubber plug of the present invention and the bottom surface of the upper cover is small, which avoids interference and ensures that the rubber plug is tightly pressed between the upper cover and the lower part, thereby increasing the size of the rubber plug. The sealing of the plug has the characteristics of tight sealing. (3) The rubber plug of the utility model is a revolving body part with a simple structure, which reduces the manufacturing cost of the mold. (4) 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.

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 medicine plug with a rotating cover, which includes an upper cover 1, a rubber plug 2, a lower part 3 and a rotating cover 4, the top of the upper cover 1 is provided with rounded corners, The top surface of loam cake 1 is provided with through hole I5, and through hole I5 is arranged on the middle part of loam cake 1, and the bottom surface of loam cake 1 is provided with two conical columns 6, and two conical columns 6 are symmetrically arranged on the through hole. Both sides of hole I5. As shown in Figures 1, 3, and 4, the top of the lower part 3 is provided with a stepped hole 7, and the top of the lower part 3 is provided with a tapered hole 8 on both sides of the stepped hole 7. The upper cover 1 is passed through two Two tapered columns 6 are respectively inserted in two tapered holes 8 and fixed on the lower part 3. The top of the rubber plug 2 is in the shape of a ball. The rubber plug 2 is arranged in the step hole 7 and the rubber plug 2 is pressed against it. Between the upper 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 Between, increase the sealability of rubber plug 2. As shown in Figure 1 or Figure 4, the top of the rubber plug 2 is provided with a through hole II9 communicating with the through hole I5, the diameter of the through hole I5 is larger than the through hole II9, and one end of the rotary cover 4 is hinged on the top of the upper cover 1 , The bottom of the rotary cover 4 is provided with a rubber block 10, the rubber block 10 is blocked in the through hole I5, and the top of the rotary cover 4 is provided with a pull ring 11.

When using a syringe to add other auxiliary drugs into the infusion bag, you only need to pull the pull ring 11 upward to rotate the rotary cover 4 upward, and the rubber block 10 is pulled out from the through hole I5, and the through hole I5 communicates with the through hole II9, 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. After dispensing the medicine, turn the rotating cover 4 downwards to insert the rubber block 10 into the through hole I5, so as to avoid the phenomenon that the medicine in the bag is polluted by the bacteria from entering the infusion bag from the outside. The design is very reasonable and can be used to hold the medicine next time. Namely recycling.

In addition, when assembling the medicine plug, it is only necessary to place the rubber plug 2 in the stepped hole 7 first, and then insert the two tapered posts 6 of the upper cover 1 into the tapered holes 8 respectively, and the tapered posts 6 and the The tapered hole 8 forms an interference fit, so that the upper cover 1 can be quickly fixed on the lower part 3 without clamping, and the assembly efficiency is very high.
