Description

Technical Field

[0001] The utility model relates to the technical field of medical infusion covers, in particular to an infusion cover with a new structure. Background Art

[0002] The infusion cap is an infusion bottle stopper, which is mainly used to seal the mouth of glass, plastic and other medicinal bottle containers. It is generally composed of an upper cover (also called an outer cover), a rubber pad (rubber stopper), and a bottom cover (inner cover). The main function of the infusion cap is to prevent the drug from overflowing, splashing, and contaminating during the infusion process. It can also protect the drug and prevent cross infection.

[0003] During actual use, medical staff will open the outer cover, and insert the bottle stopper piercer through the rubber stopper and the inner cover into the infusion bottle. For the currently common infusion caps, the rubber stopper is fixed by squeezing the inner cover and the outer cover up and down. During the process of penetrating the rubber stopper, the bottle stopper piercer may deviate due to its soft material, making it difficult to insert the bottle stopper piercer into the infusion bottle at one time, which affects the work efficiency of medical staff and the bottle stopper piercer may be contaminated if exposed for a long time. Utility Model Content

[0004] In view of the problem that the existing bottle stopper piercer may deviate during the process of penetrating the rubber stopper due to its soft material, making it difficult to insert the bottle stopper piercer into the infusion bottle at one time, the present utility model is proposed.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a new type of structural infusion cover, which includes an outer cover and an inner cover, the inner cover is slidably inserted at the bottom of the outer cover, a rubber plug is arranged between the outer cover and the inner cover, an annular ring is arranged at the inner top of the outer cover, and an annular groove is arranged on the upper end surface of the inner cover, the diameter of the annular ring is matched with the diameter of the annular groove, and the diameter of the rubber plug is matched with the inner diameter of the annular ring.

[0006] Preferably, the annular ring is coaxially arranged with the annular groove.

[0007] Preferably, a clamping top ring is fixedly provided on the inner top of the outer cover and the upper end surface of the inner cover, the diameter of the clamping top ring is smaller than the diameter of the annular ring and the annular groove, and the clamping top ring, the annular ring and the annular groove are coaxially arranged.

[0008] Preferably, a protrusion is fixedly provided on the outer circumferential surface of the inner cover, a bayonet is provided on the inner side wall of the outer cover, the upper end of the protrusion is an inclined surface, and the lower end of the protrusion is a straight surface.

[0009] Preferably, the height of the compression top ring is less than half the height of the rubber plug.

[0010] Beneficial effects of the utility model:

[0011] 1. By setting the annular ring and the annular groove, after the inner cover and the outer cover are combined, the annular ring is inserted into the annular groove to form a cavity, and the rubber plug located in the cavity is fixed by the cavity, so as to avoid the deviation of the rubber plug during the insertion of the bottle plug piercer into the infusion bottle, thereby improving the success rate of medical staff to penetrate the infusion cap and insert the bottle plug piercer into the infusion bottle at one time, and reducing the waste caused by the bottle plug piercer being exposed to the air for a long time and contamination.

[0012] 2. By setting a compression top ring, the rubber plug in the cavity is compressed from the top and bottom of the rubber plug respectively, so as to realize the secondary fixation of the rubber plug and further improve the fixing effect of the rubber plug. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] Reference Figure 1-5, is an embodiment of the utility model, which provides a new type of structural infusion cover, the new type of structural infusion cover includes an outer cover 1 and an inner cover 2, the outer cover 1 and the inner cover 2 are made of PP-polypropylene, the inner cover 2 is slidably inserted at the bottom of the outer cover 1, a rubber plug 3 is arranged between the outer cover 1 and the inner cover 2, the rubber plug 3 is made of butyl rubber, an annular ring 5 is arranged at the inner top of the outer cover 1, an annular groove 4 is arranged on the upper end surface of the inner cover 2, the annular ring 5 is matched with the diameter of the annular groove 4, when the inner cover 2 is inserted from the bottom of the outer cover 1, the annular ring 5 is inserted into the annular groove 4 to form a cavity, the diameter of the rubber plug 3 is matched with the inner diameter of the annular ring 5, and the rubber plug 3 is arranged in the cavity.

[0023] The annular ring 5 is coaxially arranged with the annular groove 4 to ensure that the annular ring 5 can be inserted into the annular groove 4 .

[0024] A clamping top ring 6 is fixedly arranged on the inner top of the outer cover 1 and the upper end surface of the inner cover 2. The diameter of the clamping top ring 6 is smaller than the diameter of the annular ring 5 and the annular groove 4. The clamping top ring 6 is coaxially arranged with the annular ring 5 and the annular groove 4. The height of the clamping top ring 6 is less than half the height of the rubber plug 3. The clamping top ring 6 clamps and fixes the rubber plug 3 from the upper end and the lower end of the rubber plug 3, further strengthening the fixing effect of the rubber plug 3.

[0025] A protrusion 7 is fixedly provided on the outer circumferential surface of the inner cover 2, and a bayonet 8 is provided on the inner side wall of the outer cover 1. The upper end of the protrusion 7 is an inclined surface, and the lower end of the protrusion 7 is a straight surface. Since the materials of the outer cover 1 and the inner cover 2 are elastic, the protrusion 7 can be compressed until it enters the bayonet 8 when the inner cover 2 is slidably inserted into the outer cover 1 to realize the closed combination of the outer cover 1 and the inner cover 2.

[0026] During use, the inner cover 2 is installed on the infusion bottle, the plug 3 is located in the annular groove 4 above the inner cover 2, and the outer cover 1 is slidably inserted on the outer side of the inner cover 2. During the installation of the outer cover 1, the annular ring 5 is inserted into the annular groove 4 to form a cavity, and the plug 3 is installed in the cavity to achieve fixation. At the same time, the compression top ring 6 of the outer cover 1 and the compression top ring 6 of the inner cover 2 achieve secondary compression of the plug 3, which improves the fixing effect. The protrusion 7 of the inner cover 2 is snapped into the matching bayonet 8 to achieve the combination of the inner cover 2 and the outer cover 1. Due to the elasticity of the plug 3, the inner cover 2 and the outer cover 1 will not loosen, avoiding the offset problem of the plug 3 due to its soft material when the bottle plug piercer is puncturing.

[0027] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
