Description

Technical Field

[0001] This utility model relates to the field of infusion cap technology, specifically to a disposable sterile sealing infusion cap. Background Technology

[0002] Infusion or large-volume injection refers to a large-dose injection solution administered into the body via intravenous drip, with a single dose exceeding 100 ml at the insertion point. It is a branch of injectable drugs and is usually packaged in glass or plastic infusion bottles or bags. It does not contain antibacterial agents and is administered by adjusting the drip rate through an infusion set to continuously and stably deliver the medication into the body.

[0003] Currently, the bottom accessories of infusion bags on the market consist of two parts: the tube body and the sealing cap. Generally, the sealing cap is inserted into the tube body for sealing, which leaves a certain gap between the tube body and the sealing cap. This gap can easily cause liquid to leak out, resulting in poor sealing performance.

[0004] Therefore, it is particularly important to improve existing disposable sterile sealing infusion caps and design a new type of disposable sterile sealing infusion cap to solve the above-mentioned technical defects and improve the overall practicality of disposable sterile sealing infusion caps. Utility Model Content

[0005] The purpose of this invention is to provide a disposable sterile sealed infusion cap to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A disposable sterile sealing infusion cap includes an infusion bag. A guide tube and a spare tube are respectively installed on the left end of the infusion bag. An installation cap is installed inside the guide tube. A silicone plug is installed on the right end inside the installation cap. An expansion plate is installed on the left end of the installation cap. A rotating sleeve is installed on the outside of the expansion plate. Anti-slip blocks are provided on the outside of the rotating sleeve. The anti-slip blocks are evenly distributed.

[0008] As a preferred embodiment of this utility model, a locking block is installed on the outside of the expansion plate, and a receiving groove is opened inside the locking block. Both the mounting cover and the outside of the expansion plate are provided with external threads.

[0009] As a preferred embodiment of this utility model, a through hole is provided in the middle of the interior of the rotating sleeve, and an internal thread is provided on the inner sidewall of the through hole at a position corresponding to the external thread. The rotating sleeve is connected to the mounting cover and the expansion plate through the through hole.

[0010] As a preferred embodiment of this utility model, a limiting piece is installed on the left end of the mounting cover, the limiting pieces are evenly distributed, and a slot is formed at the middle of the silicone plug.

[0011] As a preferred embodiment of this utility model, a sealing ring is installed on the inner wall of the guide tube at a position corresponding to the receiving groove, the expansion plate is connected to the sealing ring through the receiving groove, and both the sealing ring and the receiving groove are provided in three sets.

[0012] As a preferred embodiment of this utility model, a fixing sleeve is installed on the outside of the guide tube, an extension edge is installed on the outside of the fixing sleeve, and a spiral groove is formed on the surface of the extension edge.

[0013] As a preferred embodiment of this utility model, a placement groove is provided inside the rotating sleeve and outside the through hole, and a connecting groove is provided at the corresponding position of the placement groove and the spiral groove, and the rotating sleeve is connected to the fixed sleeve through the connecting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, by inserting an expansion plate into the interior of the guide tube, the silicone plug moves accordingly, thus sealing the guide tube. By placing a rotating sleeve outside the mounting cover, the expansion plate contracts inside the guide tube through the interaction of external and internal threads, causing the locking block to fit against the sealing ring. This allows the sealing ring to be inserted into the receiving groove. Once the sealing ring is fitted against the receiving groove, the outer extension edge of the fixing sleeve is inserted into the placement groove. By continuing to twist the rotating sleeve, the connecting groove and the spiral groove generate a threaded reaction, causing the fixing sleeve to fit against the rotating sleeve, thus covering the connection between the guide tube and the mounting cover and further completing the sealing work.

An expansion plate 6 is installed on the left end of the installation cap 4. A rotating sleeve 7 is installed on the outside of the expansion plate 6. Anti-slip blocks 701 are provided on the outside of the rotating sleeve 7. The anti-slip blocks 701 are evenly distributed. After the medicine liquid is produced, it needs to be sealed to prevent the medicine from contacting external bacteria and affecting the functionality of the medicine. By inserting the expansion plate 6 into the inside of the guide tube 2, the silicone plug 5 moves accordingly to seal the guide tube 2 and isolate the outside air from the medicine liquid inside the infusion bag 1.

[0026] For further details, please refer to Figure 1 and Figure 2 In this embodiment, a locking block 8 is installed on the outside of the expansion plate 6. The locking block 8 has a receiving groove inside. Both the mounting cover 4 and the expansion plate 6 have external threads 9. By twisting the rotating sleeve 7, the expansion plate 6 is contracted.

A connecting groove 704 is formed at the corresponding position of the placement groove 703 and the spiral groove. The rotating sleeve 7 is connected to the fixed sleeve 11 through the connecting groove 704. When the sealing ring 201 is fitted with the receiving groove, the extension edge 12 of the fixed sleeve 11 is inserted into the placement groove 703. By continuing to twist the rotating sleeve 7, the connecting groove 704 and the spiral groove generate a thread reaction, so that the fixed sleeve 11 and the rotating sleeve 7 are fitted together, thereby covering the connection between the guide tube 2 and the mounting cover 4 and further completing the sealing work.

[0031] In this embodiment, the specific implementation scenario is as follows: After the pharmaceutical liquid is produced, it needs to be sealed to prevent the liquid from coming into contact with external bacteria and affecting the functionality of the medicine. By inserting the expansion plate 6 into the inside of the guide tube 2, the silicone plug 5 moves accordingly, thus sealing the guide tube 2. By placing the rotating sleeve 7 outside the mounting cover 4, the expansion plate 6 contracts inside the guide tube 2 through the cooperation of the external thread 9 and the internal thread, so that the locking block 8 fits with the sealing ring 201, and the sealing ring 201 is inserted into the receiving groove. When the sealing ring 201 fits with the receiving groove, the outer extension edge 12 of the fixing sleeve 11 is inserted into the placement groove 703. By continuing to twist the rotating sleeve 7, the connecting groove 704 and the spiral groove produce a thread reaction, so that the fixing sleeve 11 fits with the rotating sleeve 7, thus covering the connection between the guide tube 2 and the mounting cover 4, and further completing the sealing work.
