Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, specifically to an anti-dislodgement device for intravenous infusion and an infusion stand including the device. Background Technology

[0002] Intravenous infusion refers to the administration of large doses (over 100ml per dose) of injectable solutions into the body via intravenous drip. These solutions are typically packaged in glass or plastic infusion bottles or bags, and contain no preservatives or antibacterial agents. During use, the drip rate is adjusted via an infusion set to ensure a continuous and stable flow into the vein, replenishing body fluids, electrolytes, or providing nutrients. However, a common and pressing issue in current infusion procedures is the stability of the connection between the infusion tubing and the infusion bottle. Traditionally, the puncture needle at the top of the tubing is directly inserted into the connector at the bottom of the bottle. In certain situations, such as patient movement, improper nursing procedures, or accidental external pulling, the connection between the needle and the infusion bag can easily detach, interrupting the infusion process. This not only affects the therapeutic effect but may also cause unnecessary pain and anxiety for the patient. Furthermore, detached tubing may fall to the ground, increasing the risk of cross-infection. Therefore, developing an anti-detachment device for infusions that prevents the injection head from easily separating from the infusion bottle under pulling is a pressing problem that needs to be solved.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1-4 As shown, an anti-dislodgement device for intravenous infusion mainly includes a first fixing ring 1, a second fixing ring 3, and an adjustable component 4 disposed between the first fixing ring 1 and the second fixing ring 3. The first fixing ring 1 is detachably mounted on the connector 501 at the bottom of the infusion bottle 5 and is equipped with a locking component 2 for securing the first fixing ring 1. The second fixing ring 3 is located below the first fixing ring 1 and is detachably mounted on the vent pipe 601 extending laterally from the side of the injection head 6. The vent pipe 601 is used to expel air from the infusion bottle 5 and maintain pressure balance, ensuring the safety and smoothness of the infusion process. The adjustable component 4 is disposed between the first fixing ring 1 and the second fixing ring 3 and is used to adjust and lock the distance between the first fixing ring 1 and the second fixing ring 3. Through the double fixing structure of the first fixing ring 1 and the second fixing ring 3, the connection between the infusion bottle 5 and the injection head 6 can be effectively prevented from loosening or falling off when pulled, ensuring the stability of the infusion process. The adjustable component 4 further locks the distance between the two to prevent dislodgement caused by external force or vibration.

[0023] like Figure 1 and Figure 2 As shown, the first fixing ring 1 and the second fixing ring 3 are perpendicular to each other, which enhances the stability of the overall structure and prevents the device from shifting or deforming during use. This arrangement can distribute the stress points and improve the tensile and torsional resistance of the device.

[0024] like Figure 1-3As shown, a first opening 101 is formed on the side of the first retaining ring 1, and the locking assembly 2 is located near the first opening 101. The middle of the first retaining ring 1 has a first through hole 102 for receiving the connector 501. The first through hole 102 mates with the outer wall of the connector 501. The first through hole 102 is a circular through hole with an inner diameter slightly smaller than the outer diameter of the connector 501. An anti-slip washer is provided on the inner wall of the first through hole 102 to increase the friction with the outer wall of the connector 501. The first retaining ring 1 is made of a flexible material, and its annular body has axial elastic deformation capability, allowing the first opening 101 to open or close when an external force is applied. The locking assembly 2 includes a first locking member 201 and a second locking member 202. The first locking member 201 is disposed at one end of the first retaining ring 1, and the second locking member 202 is disposed at the other end of the first retaining ring 1. They cooperate with each other to close or open the first opening 101.

[0025] Next, refer to Figure 3 and Figure 4 The figure illustrates a preferred embodiment of locking between a first locking member 201 and a second locking member 202. As shown, the first locking member 201 has a first locking block 201a and a connecting block 201b slidably connected to one end of the first locking block 201a. The second locking member 202 has a second locking block 202a and a slot 202a1 thereon. The connecting block 201b is detachably connected to the slot 202a1. The side of the connecting block 201b is provided with at least one first through hole 201b1, and the side of the first locking block 201a is provided with a plurality of second through holes 201a1 that cooperate with the first through hole 201b1 at certain intervals along its length direction. The first through hole 201b1 is connected to the second through hole 201a1 through a fixing post 201c. The first through hole 201b1 and the plurality of second through holes 201a1 that are equally spaced along the length direction of the connecting block 201b on the side of the first locking block 201a are coaxially aligned. The connecting block 201b is a rectangular hollow structure, with one end slidingly fitted onto one end of the first locking block 201a. The fixing post 201c is a metal cylindrical pin that can be inserted into the first through hole 201b1 and the second through hole 201a1 and then fixed by threads or snaps, thereby locking the relative positions of the connecting block 201b and the first locking block 201a. In other words, by aligning the second through hole 201a1 with the first through hole 201b1 at different positions, the length of the connecting block 201b extending out of the first locking block 201a can be adjusted to accommodate connectors 501 of different sizes of infusion bottles 5. The slot 202a1 on the second locking block 202a is a through rectangular groove, with its inner wall width slightly larger than the width of the connecting block 201b, ensuring that the connecting block 201b can be smoothly inserted.

[0026] Continue to refer to Figure 3 and Figure 4The connecting block 201b has elastic elements 201d at its upper and lower parts away from the first locking block 201a. Each elastic element 201d includes a spring 201d1 and a locking block 201d2 arranged in series. The spring 201d1 is fixed in a groove 201b2 formed in the upper or lower part of the connecting block 201b. The upper and lower inner walls of the slot 202a1 are both formed with slots 202a2 for accommodating the locking block 201d2. In this embodiment, the upper and lower surfaces of the connecting block 201b each have a pair of rectangular grooves. One end of the spring 201d1 is fixed to the bottom of the groove 201b2 by riveting or adhesive, and the other end is connected to the locking block 201d2. In its natural state, the locking block 201d2 partially protrudes from the surface of the connecting block 201b. The upper and lower inner walls of the slot 202a1 are provided with triangular slots 202a2 at corresponding positions. The card block 201d2 is constructed in a triangular structure. When the connecting block 201b is inserted into the slot 202a1 to the predetermined position, under the action of the spring 201d1, the card block 201d2 slides along the inner wall of the slot 202a1 and is embedded in the slot 202a2. The second locking block 202a is equipped with switches 202a3 on both the upper and lower parts. The switches 202a3 are slidably fitted into the slot 202a2. One end of the switch 202a3 is in contact with the card block 201d2, and the other end extends to the outside of the second locking block 202a. By pressing the switch 202a3, the switch 202a3 pushes one end of the card block 201d2, so that the card block 201d2 overcomes the force of the spring 201d1 and separates from the slot 202a2, thereby realizing the separation and unlocking of the connecting block 201b from the slot 202a1. After separation, the switch 202a3 automatically resets.

[0027] Then return to the reference Figure 1 and Figure 2The second fixing ring 3 has a second opening 301 formed on its side, and a fixing member 302 is also provided on the second fixing ring 3 near the second opening 301. The middle part of the second fixing ring 3 has a second through hole 304 for receiving the exhaust pipe 601. The second through hole 304 fits with the outer wall of the exhaust pipe 601. The second through hole 304 is a circular through hole, and its inner diameter is slightly smaller than the outer diameter of the exhaust pipe 601. An anti-slip washer is provided on the inner wall of the second through hole 304 to increase the friction with the outer wall of the connector 501. The second fixing ring 3 is made of a flexible material, and its annular body has axial elastic deformation capability, allowing the second opening 301 to open or close when an external force is applied. The fastener 302 includes a first fastening block 302a and a second fastening block 302b having a snap-fit ​​groove 302b1. The first fastening block 302a is disposed at one end of the second fastening ring 3 and has an elongated structure. The second fastening block 302b is disposed at the other end of the second fastening ring 3. The first fastening block 302a is engaged in the snap-fit ​​groove 302b1, which makes the second fastening block 302b have a U-shaped structure. The first fastening block 302a and the snap-fit ​​groove 302b1 are fixed by a connecting rod 401.

[0028] Continue to refer to Figure 1 and Figure 2 The adjustable component 4 has a connecting rod 401. The side of the first fixing ring 1 is provided with a first protrusion 103 and is slidably connected to one end of the connecting rod 401.
