[0001] This utility model relates to the field of infusion bottle technology, specifically a stable infusion bottle interface. Background Technology

[0002] Infusion bottles are bottles used to administer medically prepared liquids into the body when patients receive intravenous infusions. When using infusion bottles, the interface is a key component that connects the infusion bottle to the infusion tubing, and the stability of this connection is crucial.

[0003] In traditional infusion bottles, medical staff insert the needle at the top of the infusion tube into the inside of the bottle, and the needle is kept inside the bottle by the sealing ring inside. However, when patients are moved, their beds are moved, or they are given an IV infusion, the needle may become loose or even fall off, causing the IV infusion to be interrupted and posing a great safety hazard to the patient, thus reducing the security between the IV bottle and the needle. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stable infusion bottle interface, which solves the problem that the needle may loosen or even fall off when the patient moves, the bed is moved, or the infusion is performed under external force, leading to interruption of the infusion and posing a great safety hazard to the patient. This reduces the problem of the firmness between the infusion bottle and the needle.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stable infusion bottle interface, comprising a bottle body, a bottle mouth fixedly connected to the bottom of the bottle body, and a needle tube disposed inside the bottle body. The stable infusion bottle interface further comprises a reinforcing structure disposed outside the bottle mouth and the needle tube; an anti-detachment structure disposed below the outer wall of the needle tube; wherein, the reinforcing structure reinforces the connection between the bottle mouth and the needle tube, and the anti-detachment structure prevents the reinforcing structure from detaching from the needle tube when not in use; the reinforcing structure comprises a sleeve fitted onto the outer wall of the needle tube; a first thread is formed on the inner wall of the sleeve; a second thread is formed on the outer wall of the needle tube and is threaded to the first thread; a shell is fixedly connected to the top of the sleeve and penetrates the needle tube; a third thread is formed on the inner wall of the shell; a fourth thread is formed on the outer wall of the bottle mouth and is threaded to the third thread; wherein, the engagement of the first and second threads allows the sleeve to move on the needle tube, and the engagement of the third and fourth threads allows the shell to rotate onto the bottle mouth.

[0006] Preferably, the anti-detachment structure includes a disc fixed to the lower outer wall of the syringe; a collar fixed to the top of the disc; wherein the disc and the collar limit the position of the sleeve.

[0007] Preferably, a rubber ring is fixed inside the bottle opening.

[0009] This invention provides a stable infusion bottle interface. It offers the following advantages: This stable infusion bottle interface, through the cooperation of a sleeve, a first thread, a second thread, a shell, a third thread, and a fourth thread, securely connects the bottle opening to the needle, effectively enhancing the interface's stability. This solves the problem of the needle easily loosening or even falling off when subjected to external force during patient movement, bed transport, or infusion, leading to infusion interruption and posing a significant safety hazard to the patient. Thus, it reduces the problem of insufficient stability between the infusion bottle and the needle.

[0010] By using the combination of the disc and the collar, the sleeve is prevented from detaching from the needle when the reinforcement structure is not in use. This solves the problem that when the reinforcement structure is not in use, the sleeve may shake and detach from the outer wall of the needle when the infusion tubing is being transported or removed, requiring medical staff to rotate the sleeve back onto the needle when it is used.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] When patients are moving, their beds are being moved, or they are receiving intravenous infusions, the needle may become loose or even fall off, causing the infusion to be interrupted and posing a great safety hazard to the patient. This reduces the security between the infusion bottle and the needle.

[0015] In view of this, the present invention provides a stable infusion bottle interface. Through the cooperation of a sleeve, a first thread, a second thread, a shell, a third thread, and a fourth thread, the bottle mouth and the needle are firmly connected together, which effectively enhances the stability of the interface and solves the problem that the needle is prone to loosening or even falling off when the patient moves, the bed is moved, or the infusion is performed under external force, which can lead to interruption of the infusion and pose a great safety hazard to the patient, thereby reducing the firmness between the infusion bottle and the needle.

[0016] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0017] Example 1: By Figures 1-5 It is known that a stable infusion bottle interface includes a bottle body 1, a bottle mouth 2 fixedly connected to the bottom of the bottle body 1, and a needle tube 3 disposed inside the bottle body 1. The stable infusion bottle interface also includes a reinforcing structure 7 and an anti-detachment structure 8. The reinforcing structure 7 is disposed outside the bottle mouth 2 and the needle tube 3; the anti-detachment structure 8 is disposed below the outer wall of the needle tube 3. The reinforcing structure 7 reinforces the bottle mouth 2 and the needle tube 3, and the anti-detachment structure 8 prevents the reinforcing structure 7 from detaching from the needle tube 3 when not in use. In the specific implementation process, it is worth noting that the bottom of the needle tube 3 is connected to the infusion tubing. During infusion, medical staff insert the needle tube 3 into the inside of the bottle mouth 2 and into the bottom of the bottle body 1. After completion, the staff reinforces the bottle mouth 2 and the needle tube 3 with the reinforcing structure 7. At this time, the liquid medicine inside the bottle body 1 flows into the cavity inside the needle tube 3 through the through hole at the top and finally flows into the infusion tubing. The anti-detachment structure 8 prevents the reinforcing structure 7 from detaching from the needle tube 3 when not in use. The reinforcing structure 7 includes a sleeve 71, a first thread 72, a second thread 73, a housing 74, a third thread 75, and a fourth thread 76. The sleeve 71 is fitted onto the outer wall of the needle tube 3; the first thread 72 is formed on the inner wall of the sleeve 71; the second thread 73 is formed on the outer wall of the needle tube 3 and is threaded to the first thread 72; the housing 74 is fixed to the top of the sleeve 71 and penetrates the needle tube 3; the third thread 75 is formed on the inner wall of the housing 74; the fourth thread 76 is formed on the outer wall of the bottle mouth 2 and is threaded to the third thread 75. The sleeve 71 moves on the needle tube 3 through the cooperation of the first thread 72 and the second thread 73, and the housing 74 rotates onto the bottle mouth 2 through the cooperation of the third thread 75 and the fourth thread 76. In the specific implementation process, it is worth noting that the pitches of the first thread 72, the second thread 73, the third thread 75, and the fourth thread 76 are equal. When the medical staff inserts the needle 3 into the bottle mouth 2, the medical staff rotates the sleeve 71. The sleeve 71 drives the first thread 72 to rotate on the third thread 75, thereby causing the sleeve 71 to move the housing 74. The housing 74 drives the third thread 75 to rotate. At this time, the third thread 75 rotates along the fourth thread 76. After the housing 74 is moved to the final position, the medical staff stops rotating the sleeve 71. The sleeve 71 and the housing 74 work together to firmly connect the bottle mouth 2 and the needle 3 together, effectively enhancing the stability of the interface. Example 2: From Figures 1-5 It can be seen that the anti-detachment structure 8 includes a disc 81 and a collar 82. The disc 81 is fixed to the lower part of the outer wall of the needle tube 3; the collar 82 is fixed to the top of the disc 81; wherein, the sleeve 71 is limited by the disc 81 and the collar 82. In the specific implementation process, it is worth noting that when the needle tube 3 is not used, the sleeve 71 is inserted inside the collar 82, and the bottom of the sleeve 71 is in contact with the disc 81. The collar 82 and the disc 81 can prevent the sleeve 71 from sliding down further, thereby preventing the sleeve 71 from detaching from the needle tube 3. Furthermore, a rubber ring 4 is fixed inside the bottle opening 2; In the specific implementation process, it is worth noting that the rubber ring 4 is made of EPDM rubber. At the same time, the rubber ring 4 has good elasticity and sealing performance, so that when the needle tube 3 is connected to the bottle mouth 2 during the infusion process, the rubber ring 4 can fit tightly against the outer wall of the needle tube 3, effectively preventing drug leakage and ensuring the safety and accuracy of the infusion. Furthermore, the top and bottom of the rubber ring 4 are respectively attached to the first annular ring 5 and the second annular ring 6, and the first annular ring 5 and the second annular ring 6 are respectively fixed to the inner wall of the bottle mouth 2. In the specific implementation process, it is worth noting that the first annular ring 5 and the second annular ring 6 play a role in further fixing and supporting the rubber ring 4, so as to prevent the rubber ring 4 from shifting or deforming during use, thereby ensuring that the rubber ring 4 always maintains good sealing performance.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
