Description

Technical Field

[0001] This utility model specifically relates to an infusion set anti-dislodgement fixing device. Background Technology

[0002] Intravenous infusion therapy is a common clinical treatment method and is widely used.

[0003] In clinical practice, an infusion set consists of a puncture needle inserted into an infusion bottle without any other fixing device. During the infusion process, if the patient is active or in an unstable state, such as turning over, moving, or eating, the puncture needle may fall off the infusion bottle.

[0004] If an IV needle falls out, it can cause fluid leakage, which not only interrupts treatment and wastes medication, but if the leaked medication is chemotherapy, it can also cause unnecessary harm to patients and medical staff. In clinical practice, nurses need to frequently check on patients to ensure that the IV needle is secure, which not only increases the workload of nurses, but also leads to a waste of nursing resources.

[0005] Furthermore, if the puncture needle falls out, a new infusion set must be replaced, which not only wastes medical resources but also increases the financial burden on patients. Therefore, designing an effective anti-dislodgement fixation device is crucial to ensuring the smooth progress of infusion therapy.

[0006] Chinese patent CN202121302887.1, entitled "Anti-dislodgement device for infusion set puncture needles," describes a device comprising a fixed rod, characterized in that it further comprises: a first half-clamp and a second half-clamp, rotatably connected to the fixed rod; a housing, fixedly connected to the fixed rod; a stabilizing rod, slidably connected inside the housing; a pawl, rotatably connected inside the housing; and a rack, fixedly connected to the stabilizing rod. A second restoring spring is provided between the pawl and the housing; a slot is provided on the stabilizing rod; an infusion alarm is provided on the housing; and both the first and second half-clamps have placement cavities.

[0007] As shown in the attached drawings of patent CN202121302887.1, this patent uses a first half-clamp and a second half-clamp to form a latch to fix the mouth of the infusion bottle. At the same time, the puncture needle is fixed in the slot on the stabilizing rod. Then, the stabilizing rod is pushed to abut the puncture needle against the bottle stopper of the infusion bottle, increasing the stability between the puncture needle and the infusion bottle. The technical solution of this patent can achieve the function of locking and fixing the infusion bottle, but the size cannot be adjusted and it is not applicable to different sizes of infusion bottles. In addition, for patients who need to receive multiple bottles of medicine at one time, it is more troublesome to change the infusion bottle when the anti-dislodgement device of the infusion set is used, which is inconvenient.

Detailed Implementation

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-13 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0022] like Figure 1 , 2 As shown in Figure 3, an anti-dislodgement device for infusion sets includes an infusion bottle fixing clip 1, a puncture needle fixing clip 2, an adjustment mechanism 3, a fixing clip mounting block 4, and an unlocking mechanism 5. The infusion bottle fixing clip 1 and the puncture needle fixing clip 2 are mounted on the fixing clip mounting block 4. The adjustment mechanism 3 is located inside the fixing clip mounting block 4. The adjustment mechanism 3 can adjust the tightness of the infusion bottle fixing clip 1 on the infusion bottle and the tightness of the puncture needle fixing clip 2 on the puncture needle. The unlocking mechanism 5 can release the fixing of the infusion bottle fixing clip 1 on the infusion bottle and the fixing of the puncture needle fixing clip 2 on the puncture needle with one click.

[0023] The infusion bottle fixing clip 1 can be attached to the neck of the infusion bottle. The main function of the infusion bottle fixing clip 1 is to fix the entire device stably on the infusion bottle, ensuring the overall stability of the device.

[0024] The main function of the puncture needle fixation clip 2 is to fix the puncture needle in place, preventing the puncture needle from falling off the infusion bottle when the patient is moving around a lot or in an unstable state.

[0025] The main function of the adjustment mechanism 3 is to adjust and limit the tightness of the infusion bottle fixing clip 1 and the insertion depth of the puncture needle fixing clip 2, so as to facilitate the fixing of the puncture needle and improve the versatility of the device, making the device suitable for infusion bottles of different specifications.

[0026] The main function of the fixing block 4 is to serve as a carrier for the installation of the device. The infusion bottle fixing block 1, the puncture needle fixing block 2, the adjustment mechanism 3, and the unlocking mechanism 5 are all installed on the fixing block 4.

[0027] The main function of the unlocking mechanism 5 is to release the infusion bottle fixing clip 1 from the infusion bottle and the puncture needle fixing clip 2 from the puncture needle with one click, making it convenient to replace the infusion bottle.

[0028] like Figure 2 , 4 As shown in Figures 10 and 12, the infusion bottle fixing clip 1 includes two arc-shaped fixing clips 11. The arc-shaped fixing clips 11 are plastic clips with a semi-circular cross-section. In this embodiment, PP plastic is preferably used. The two arc-shaped fixing clips 11 form a circular opening in the middle after being closed. The infusion bottle fixing clip 1 is clamped to the neck of the infusion bottle through the opening.

[0029] To facilitate the connection between the arc-shaped fixing clip 11 and the adjustment mechanism 3, a rectangular protrusion is provided on the arc-shaped surface of one end of the arc-shaped fixing clip 11, perpendicular to the arc-shaped surface. This protrusion is named fixing platform 21. The arc-shaped fixing clip 11 is connected to the adjustment mechanism 3 through the fixing platform 21.

[0030] like Figure 2 , 5 As shown in Figures 10 and 12, the puncture needle retainer 2 includes a puncture needle clamp 21, which is a plastic sheet with a circular cross-section. In this embodiment, PP plastic is preferably used. A rectangular notch is provided on the surface of the puncture needle clamp 21 and the arc-shaped side, which is named the clamp opening 22. The puncture needle in the infusion set can be clamped at the clamp opening 22 on the puncture needle clamp 21.

[0031] To facilitate the connection between the adjustment mechanism 3 and the puncture needle clamp 21, a rectangular connecting platform protrudes outward on the surface of the puncture needle clamp 21, through which the adjustment mechanism 3 can be connected to the puncture needle clamp 21.

[0032] To facilitate adjustment of the distance between the puncture needle and the infusion bottle opening, a rectangular plate is integrally provided on the puncture needle clamp 21. This plate is named the adjustment push plate 23. Pushing the adjustment push plate 23 can move the puncture needle fixing clip 2, thereby adjusting the distance between the puncture needle and the infusion bottle opening.

[0033] like Figure 2 , 6 As shown in 7, 8, 9 and 10, the fixing card mounting block 4 is a rectangular plastic block with a certain thickness. In this embodiment, PP plastic is preferably used.

[0034] To facilitate the installation of the infusion bottle fixing clip 1 and the infusion bottle adjustment mechanism 301 in the adjustment mechanism 3, two rectangular grooves are provided on the front of the fixing clip mounting block 4. These grooves are named adjustment plate slide grooves 41. The two adjustment plate slide grooves 41 are spaced apart. The adjustment plate in the infusion bottle adjustment mechanism 301 is placed in the adjustment plate slide grooves 41 and can slide within the adjustment plate slide grooves 41.

[0035] In order to increase the sliding stroke of the adjustment plate in the adjustment plate groove 41 of the infusion bottle adjustment mechanism 301 and increase the adjustment range of the infusion bottle fixing clip 1 to accommodate infusion bottles of different diameters, a rectangular platform is integrally provided on the side of the fixing clip mounting block 4 at the position corresponding to the opening of the adjustment plate groove 41. This rectangular platform is named extension platform 43. A groove communicating with the adjustment plate groove 41 is provided on the extension platform 43. This arrangement increases the sliding stroke of the adjustment plate in the adjustment plate groove 41 without increasing the width of the fixing clip mounting block 4.

[0036] There are two extension platforms 43, located on two opposite sides of the fixing card mounting block 4. This arrangement allows the two arc-shaped fixing cards 11 connected to the adjustment plate to move simultaneously towards or away from each other along the adjustment plate slide groove 41 on the fixing card mounting block 4, thereby adjusting the size of the slot.

[0037] Definition: In this embodiment, the surface on which the infusion bottle fixing clip 1 is installed is the front side, and the other side opposite it is the back side.

[0038] To facilitate the installation of the puncture needle fixing clip 2, a rectangular groove is provided on the back of the fixing clip mounting block 4, which is named slot 42. The adjusting plate 307 in the adjusting mechanism 3 is inserted into the slot 42, and the insertion depth in the slot 42 is adjusted by the puncture needle adjusting mechanism 302 in the adjusting mechanism 3.

[0039] In order to facilitate the restriction of the position of the adjusting plate 307 inserted into the slot 42, a stepped groove is recessed on the surface of the slot 42. This stepped groove is named the plate limiting plate mounting groove 44. The plate limiting plate 308 in the puncture needle adjustment mechanism 302 is installed in the plate limiting plate mounting groove 44.

[0040] To ensure the stability of the adjustment mechanism 3 when installed on the fixing card mounting block 4 and to ensure the stable operation of the adjustment mechanism 3, a rectangular panel 6 is fixed to the front of the fixing card mounting block 4 with screws. The panel 6 closes the adjustment plate slide groove 41 on the front of the fixing card mounting block 4.

[0041] On the back of the fixing card mounting block 4, a rectangular base plate 7 is fixed with screws. The base plate 7 closes the slot 42 on the back of the fixing card mounting block 4. The arrangement of the panel 6 and the base plate 7 can ensure the stability of the adjustment mechanism 3 in the fixing card mounting block 4 during installation and operation.

[0042] like Figure 4 , 5 As shown in Figures 6, 7, 10 and 11, the adjustment mechanism 3 includes an infusion bottle adjustment mechanism 301 and a puncture needle adjustment mechanism 302. The main function of the infusion bottle adjustment mechanism 301 is to adjust and limit the tightness of the infusion bottle fixing clip 1, and the main function of the puncture needle adjustment mechanism 302 is to adjust and limit the insertion depth of the puncture needle fixing clip 2.

[0043] The infusion bottle adjustment mechanism 301 includes an adjustment plate and an adjustment plate limiting piece 304. The adjustment plate includes a first adjustment plate 303 and a second adjustment plate 305. The first adjustment plate 303 and the second adjustment plate 305 are respectively placed in two adjustment plate grooves 41 on the fixing card mounting block 4. The main function of the adjustment plate limiting piece 304 is to limit the position of the first adjustment plate 303 and the second adjustment plate 305.

[0044] The first adjusting plate 303 and the second adjusting plate 305 are rectangular plastic plates with a certain thickness. One end of the first adjusting plate 303 and the second adjusting plate 305 can be inserted into the adjusting plate groove 41, and the thickness of the first adjusting plate 303 and the second adjusting plate 305 is the same as the depth of the adjusting plate groove 41. The first adjusting plate 303 and the second adjusting plate 305 can slide stably in the adjusting plate groove 41.

[0045] In order to restrict the position of the first adjustment plate 303 and the second adjustment plate 305, a limiting groove 310 with a triangular cross-section is recessed on the front side of the first adjustment plate 303 and the second adjustment plate 305. At the same time, a limiting tooth 311 is provided on the adjustment plate limiting piece 304 to cooperate with it. Through the cooperation of the limiting tooth 311 and the limiting groove 310, the adjustment plate limiting piece 304 restricts the position of the first adjustment plate 303 and the second adjustment plate 305.

[0046] The adjusting plate limiting piece 304 is a rectangular plastic piece. The adjusting plate limiting piece 304 is installed on the panel 6. In order to facilitate the installation of the adjusting plate limiting piece 304, a rectangular notch is opened on the panel 6 at the position corresponding to the adjusting plate slide groove 41. The size of the notch is slightly larger than the size of the adjusting plate limiting piece 304. The adjusting plate limiting piece 304 is located at this notch, and one end of the adjusting plate limiting piece 304 is integrally connected to the panel 6. Since the adjusting plate limiting piece 304 is made of plastic and the panel 6 is only connected at one end, when force is applied to the adjusting plate limiting piece 304, the adjusting plate limiting piece 304 can undergo elastic deformation relative to the panel 6 at the connection point, thereby releasing the engagement of the adjusting plate limiting piece 304 with the first adjusting plate 303 and the second adjusting plate 305.

[0047] Since the movement directions of the first adjusting plate 303 and the second adjusting plate 305 are opposite, the directions of the limiting grooves 310 opened on the first adjusting plate 303 and the second adjusting plate 305 are also opposite. In order to ensure that the adjusting plate limiting piece 304 restricts the position of the first adjusting plate 303 and the second adjusting plate 305, the limiting teeth 311 opened on the adjusting plate limiting piece 304 should be set in two segments with opposite directions. The two segments of limiting teeth 311 with different directions cooperate with the first adjusting plate 303 and the second adjusting plate 305 respectively.

[0048] When the adjustment plate limiting piece 304 is released from its engagement with the first adjustment plate 303 and the second adjustment plate 305, two return springs 306 are provided in the adjustment plate groove 41 to facilitate the reset of the first adjustment plate 303 and the second adjustment plate 305. One end of the return spring 306 is connected to the end of the first adjustment plate 303 and the second adjustment plate 305 inserted into the adjustment plate groove 41, and the other end abuts against the inner wall of the adjustment plate groove 41. When the first adjustment plate 303 and the second adjustment plate 305 move toward each other, the return spring 306 is compressed by force. After the first adjustment plate 303 and the second adjustment plate 305 are released from their engagement with the adjustment plate limiting piece 304, the first adjustment plate 303 and the second adjustment plate 305 are reset under the action of the return spring 306.

[0049] Regarding the connection between the first adjusting plate 303 and the second adjusting plate 305 and the infusion bottle fixing clip 1, one end of the first adjusting plate 303 and the second adjusting plate 305 that is not inserted into the adjusting plate groove 41 is fixedly connected to the fixing platform 12 on the arc-shaped fixing clip 11. In this way, the arc-shaped fixing clip 11 can adjust the size of the clip as the first adjusting plate 303 and the second adjusting plate 305 move, thereby realizing the clipping of the infusion bottle fixing clip 1 onto the infusion bottle. In order to prevent the clip of the infusion bottle fixing clip 1 from being too small, the fixing platform 12 and the expansion platform 43 will interfere with each other. A clearance opening 13 is provided on the fixing platform 12 to allow the expansion platform 43 to move.

[0050] The puncture needle adjustment mechanism 302 includes an adjustment plate 307 and a plate limiting piece 308. The adjustment plate 307 is a plastic piece with a rectangular cross-section. One end of the adjustment plate 307 is fixedly connected to the puncture needle clamp 21, and the other end is inserted into the slot 42. The plate limiting piece 308 is a rectangular plastic piece, and one end of the plate limiting piece 308 is fixed in the plate limiting piece mounting groove 44 with a screw.

[0051] The adjusting insert plate 307 engages with the insert plate limiting piece 308 to adjust the insertion depth of the adjusting insert plate 307 in the slot 42. To facilitate the engagement, a limiting groove 310 is provided on the surface of the adjusting insert plate 307, and a limiting tooth 311 is provided on the surface of the insert plate limiting piece 308 away from the fixed end. The adjusting insert plate 307 and the insert plate limiting piece 308 engage with each other through the limiting groove 310 and the limiting tooth 311.

[0052] like Figure 6 , 7 As shown in Figures 10 and 11, in order to facilitate the release of the infusion bottle fixing clip 1 from the infusion bottle and the release of the puncture needle fixing clip 2 from the puncture needle, an unlocking mechanism 5 is provided on the fixing clip mounting block 4. The unlocking mechanism 5 includes an infusion bottle unlocking mechanism 51 and a puncture needle unlocking mechanism 52.

[0053] To facilitate the installation of the infusion bottle unlocking mechanism 51, a circular through hole is provided on the fixing card mounting block 4, penetrating the fixing card mounting block 4 and the base plate 7. This through hole is named unlocking hole 45. The unlocking hole 45 is located between the two adjustment plate slide grooves 41 on the fixing card mounting block 4, corresponding to the position of the adjustment plate limiting piece 304. A first unlocking button 53 is placed in the unlocking hole 45, and an unlocking rod 55 is fixed on the first unlocking button 53. The unlocking rod 55 passes through the unlocking hole 45 and is connected to the adjustment plate limiting piece 304 with glue. Pressing the first unlocking button 53 can apply force to the adjustment plate limiting piece 304, releasing the limiting engagement of the adjustment plate limiting piece 304 on the first adjustment plate 303 and the second adjustment plate 305.

[0054] To prevent the unlocking lever 55 on the first unlocking button 53 from interfering with the position of the adjusting plate 307, a rectangular through hole is provided on the adjusting plate 307. This through hole is named the plate clearance hole 309. The first unlocking button 53 is cleared through the plate clearance hole 309 to ensure that the adjusting plate 307 and the first unlocking button 53 can operate normally.

[0055] To facilitate the release of the engagement between the adjusting plate 307 and the plate limiting piece 308, a circular unlocking hole 45 is provided on the base plate 7 at a position corresponding to the plate limiting piece 308. A second unlocking button 54 is placed in this unlocking hole 45, and an unlocking rod 55 is also connected to the second unlocking button 54. The unlocking rod 55 passes through the unlocking hole 45 and is connected to the plate limiting piece 308 with glue. Pressing the second unlocking button 54 can apply pressure to the plate limiting piece 308, causing the plate limiting piece 308 to undergo elastic deformation, thereby releasing the engagement between the adjusting plate 307 and the plate limiting piece 308.

[0056] The insert plate limiting piece 308 and the adjusting plate limiting piece 304 are made of PP plastic with a certain degree of elasticity. One end of the insert plate limiting piece 308 and the adjusting plate limiting piece 304 is fixed and the other end is not fixed. When pressure is applied to the insert plate limiting piece 308 and the adjusting plate limiting piece 304, the insert plate limiting piece 308 and the adjusting plate limiting piece 304 can undergo elastic deformation along the fixed part.

[0057] like Figure 1 and 3 As shown, when using glass infusion bottles, in order to facilitate hanging the infusion bottle on the infusion pole, a fixing net bag 8 can be fixed on the fixing clip mounting block 4. The fixing net bag 8 is an arc-shaped mesh. Velcro is fixed to the radial side of the fixing net bag 8. This Velcro is named Velcro adjustment piece 82. By cooperating with the Velcro adjustment piece 82, the arc-shaped mesh can be closed into a conical net bag, which is convenient for placing the infusion bottle.

[0058] Four fixing straps 81 are integrally fixed to the edge of the fixing net bag 8. Velcro is fixed to the end of the fixing straps 81. The four fixing straps 81 can be gathered together to form two hanging ropes, making it convenient to hang the fixing net bag 8 on the infusion pole.

[0059] like Figure 13 As shown, regarding the usage process of this embodiment, when using it, first place the neck of the infusion bottle into the slot formed by the two arc-shaped fixing clips 11, and then pinch the two arc-shaped fixing clips 11. At this time, the first adjusting plate 303 and the second adjusting plate 305 move towards each other until the inner side of the arc-shaped fixing clip 11 is close to the neck of the infusion bottle. At this time, under the action of the adjusting plate limiting piece 304, the arc-shaped fixing clip 11 is in a stable fixed state. Then, use the puncture needle to puncture the infusion bottle. After the puncture is completed, push the adjusting push plate 23 to adjust the position of the puncture needle clamp 21 until the puncture needle clamp 21 is in contact with the plane on the tail of the puncture needle, and place the infusion tube into the clamp 22, thus completing the fixation of the puncture needle. When it is necessary to replace the infusion bottle, first press the second unlock button 54. At this time, the puncture needle clamp 21 can be pulled down to release the restriction on the position of the puncture needle. Then press the first unlock button 53. Under the action of the reset spring 306, the two arc-shaped fixing clips 11 will automatically pop open to release the restriction of the infusion bottle fixing clip 1 on the infusion bottle. At this time, the entire infusion set anti-dislodgement fixing device can be removed, and the infusion bottle can be replaced.

[0060] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
