Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a restraint device for infusion tubes and infusion bottles. Background Technology

[0002] When using an infusion bottle, a stopper puncturer is needed to puncture the rubber stopper at the bottle opening for infusion. Regardless of whether it is an infusion bottle, infusion bag, or stopper puncturer, there is a risk of it falling off due to strong external force during the infusion process.

[0003] To address the issue of IV bags or bottles falling off, a round hole lug is typically made on the edge of the IV bag, which is then fitted onto an external suspension rod. Alternatively, a net can be used to hold the IV bottle, which is then hung on the external suspension rod. Both methods can reduce the risk of IV bags or bottles falling off to some extent.

[0004] To address the issue of the bottle stopper detaching from the rubber stopper at the bottle opening, clinical nurses typically insert the stopper as deeply as possible into the bottle opening. This improves the structural stability between the stopper and the rubber stopper, making it less prone to detachment. However, this can lead to wasted intravenous fluids. For example, if the intravenous fluid level is below the inlet port of the stopper but above the inner surface of the rubber stopper, the intravenous solution in that area cannot be fully utilized and remains in the infusion bag or bottle.

[0005] However, combining the two technologies mentioned above—that is, using a net to hold the infusion bottle and suspending it on an external suspension rod, or having an ear-shaped bracket on the infusion bag to suspend it on an external suspension rod, while inserting the stopper puncturist as deeply as possible into the bottle opening—while preventing the infusion bottle, infusion bag, and stopper puncturist from falling off, still has drawbacks, such as: waste of infusion solution, lack of aesthetic appeal of the net, and the continued high risk of the stopper puncturist falling off.

[0006] Therefore, there is an urgent need to propose a constraint device that can solve the above-mentioned technical problems. Utility Model Content

[0007] To address the problems existing in the prior art, this utility model provides a restraint device for infusion tubing and infusion bottle. With this restraint device, on the one hand, the entire restraint device is suspended on an external suspension rod by a limiting ring. On the other hand, under the sleeve action of the needle limiting ring and the bottle limiting ring, the bottle stopper puncturist and the infusion bottle are not easy to break free and slip off.

[0008] On the other hand, the groove on the limiting ring can be engaged with the external suspension rod, so even if the infusion bottle and infusion tube shake as a whole, it is not easy to slip out of the external suspension rod, which improves the overall structural stability of the restraint device.

[0009] In addition, in terms of overall effect, this application can not only achieve the function of restraining the bottle stopper puncture device, but also the function of restraining the infusion bottle, and can also avoid the problem of insufficient utilization of infusion solution due to the bottle stopper puncture device being inserted too deeply into the infusion bottle port.

[0010] In addition, this application can adjust the relative displacement of the first connecting bar and the second connecting bar in the longitudinal direction according to the distance between the external suspension rod and the bottle stopper puncture device, by means of the cooperation of the limiting groove and the one-way locking tooth, so as to adapt to different distances between the external suspension rod and the bottle stopper puncture device.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0012] This application proposes a restraint device for an infusion tube and infusion bottle, including a limiting ring, a first connecting strip, a second connecting strip, a needle limiting ring, and a bottle limiting ring. The limiting ring is connected to the first connecting strip. The first connecting strip has a limiting groove with several first toothed grooves at its end away from the limiting ring. The second connecting strip has several rows of first one-way locking teeth at its end near the first connecting strip. The second connecting strip can be inserted into the limiting groove for one-way locking. The needle limiting ring and the bottle limiting ring are connected sequentially at the end of the second connecting strip away from the first one-way locking teeth. Both the needle limiting ring and the bottle limiting ring are self-adhesive wrap-around rings. A groove is formed on the inner circumference of the limiting ring away from the first connecting strip. The cross-section of the groove is at least two-thirds of a circle. The groove is used to lock an external suspension rod.

[0013] To solve its technical problem, the further technical solution adopted by this utility model is as follows:

[0014] Optionally, in the above-mentioned constraint device, the inner and outer surfaces of the needle limiting ring and the bottle limiting ring are both hook surfaces and rough surfaces, and the needle limiting ring and the bottle limiting ring are both wrap-around self-adhesive rings.

[0015] Optionally, in the above-mentioned restraint device, the bottle body limiting ring can be sleeved on the neck of the infusion bottle, and the needle limiting ring can be sleeved on the connection between the bottle stopper puncturist and the air inlet tube of the infusion tube.

[0016] Optionally, in the above-mentioned constraint device, the limiting ring, the needle limiting ring, and the bottle limiting ring are all made of nylon; the first connecting strip, the limiting groove, and the second connecting strip are all made of plastic.

[0017] Further optionally, in the above-mentioned constraint device, the limiting ring and the first connecting strip, and the second connecting strip and the needle limiting ring and the bottle limiting ring are all sewn together.

[0018] Further optionally, in the above-mentioned constraint device, along the width direction of the second connecting strip, a plurality of second one-way locking teeth are provided on both sides of the second connecting strip, and a plurality of second tooth grooves adapted to the second one-way locking teeth are provided on both sides inside the limiting groove.

[0019] Optionally, in the above-mentioned constraint device, the end of the second connecting bar near the limiting groove is designed with a rounded wedge structure.

[0020] Alternatively, in the aforementioned constraint device, the end of the first connecting strip near the limiting groove is designed with a rounded wedge structure.

[0021] Compared with the prior art, this application has the following technical effects:

[0022] On the one hand, the limiting ring of this application is connected to the first connecting strip. The first connecting strip is engaged with the second connecting strip through the cooperation of the limiting groove and the one-way locking tooth. One end of the second connecting strip is connected to the needle limiting ring and the bottle limiting ring in sequence. The needle limiting ring and the bottle limiting ring can be connected to the connection between the bottle stopper puncturist and the air inlet tube, and the neck of the infusion bottle in a loop-like manner, so that the entire restraint device is suspended on the external suspension rod through the limiting ring. At the same time, under the sleeve action of the needle limiting ring and the bottle limiting ring, the bottle stopper puncturist and the infusion bottle are not easy to break free and slip off.

[0023] On the other hand, a groove is provided on the inner circumference of the limiting ring of this application away from the first connecting strip. The cross section of the groove is at least two-thirds of a circle, so that the groove can be engaged with the external suspension rod. Even if the infusion bottle and infusion tube shake as a whole, it is not easy to slip out of the external suspension rod, which improves the overall structural stability of the restraint device.

[0024] In addition, in terms of overall effect, this application can not only achieve the function of restraining the bottle stopper puncture device, but also the function of restraining the infusion bottle, and can also avoid the problem of insufficient utilization of infusion solution due to the bottle stopper puncture device being inserted too deeply into the infusion bottle port.

[0025] In addition, this application can adjust the relative displacement of the first connecting bar and the second connecting bar in the longitudinal direction according to the distance between the external suspension rod and the bottle stopper puncture device, by means of the cooperation of the limiting groove and the one-way locking tooth, so as to adapt to different distances between the external suspension rod and the bottle stopper puncture device.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Example 1

[0036] like Figures 1 to 5As shown, in one embodiment of this application, a restraint device for an infusion tube and infusion bottle includes a limiting ring 1, a first connecting strip 2, a second connecting strip 3, a needle limiting ring 4, and a bottle limiting ring 5. The limiting ring 1 is connected to the first connecting strip 2. The first connecting strip 2 has a limiting groove 21 with a plurality of first toothed grooves 211 at the end away from the limiting ring 1. The second connecting strip 3 has a plurality of rows of first one-way locking teeth 31 at the end near the first connecting strip 2. The second connecting strip 3 can be inserted into the limiting groove 21 for one-way locking. The end of the second connecting strip 3 away from the first one-way locking teeth 31 is sequentially connected to the needle limiting ring 4 and the bottle limiting ring 5. The needle limiting ring 4 and the bottle limiting ring 5 are both wrap-around self-adhesive rings. The inner circumference of the limiting ring 1 is provided with a groove 11 on the side away from the first connecting strip 2. The cross section of the groove 11 is at least two-thirds of a circle. The groove 11 is used to lock an external suspension rod.

[0037] In this embodiment, on the one hand, the limiting ring is connected to the first connecting strip, and the first connecting strip is engaged with the second connecting strip through the cooperation of the limiting groove and the one-way locking tooth. One end of the second connecting strip is connected to the needle limiting ring and the bottle limiting ring in sequence. The needle limiting ring and the bottle limiting ring can be connected to the connection between the bottle stopper puncturist and the air inlet tube, and the neck of the infusion bottle in a loop-like manner, so that the entire restraint device is suspended on the external suspension rod through the limiting ring. At the same time, under the sleeve action of the needle limiting ring and the bottle limiting ring, the bottle stopper puncturist and the infusion bottle are not easy to break free and slip off.

[0038] On the other hand, a groove is provided on the inner circumference of the limiting ring away from the first connecting strip. The cross section of the groove is at least two-thirds of a circle, so that the groove can be engaged with the external suspension rod. Even if the infusion bottle and infusion tube shake as a whole, it is not easy to slip out of the external suspension rod, which improves the overall structural stability of the restraint device.

[0039] In addition, in terms of overall effect, it can not only restrain the bottle stopper puncture device, but also restrain the infusion bottle, and can also avoid the problem of insufficient utilization of infusion solution due to the bottle stopper puncture device being inserted too deeply into the infusion bottle port.

[0040] In addition, the relative displacement of the first connecting bar and the second connecting bar in the longitudinal direction can be adjusted by means of the cooperation of the limiting groove and the one-way locking teeth, according to the distance between the external suspension rod and the bottle stopper puncturer, so as to adapt to different distances between the external suspension rod and the bottle stopper puncturer.

[0041] In another embodiment of this application, such as Figures 1 to 3 As shown, the inner and outer surfaces of the needle limiting ring 4 and the bottle limiting ring 5 are both hooked and rough (not shown in the figure), and both the needle limiting ring 4 and the bottle limiting ring 5 are wrap-around self-adhesive rings.

[0042] In this embodiment, since both the front and back sides of the needle limiting ring and the bottle limiting ring are designed with hook and rough surfaces, they are connected by a self-adhesive method of bending the upper and lower ends of the needle limiting ring and the bottle limiting ring, which facilitates disassembly for disinfection and cleaning, and also facilitates rapid clinical assembly and use.

[0043] In another embodiment of this application, such as Figures 1 to 3 As shown, the bottle body limiting ring 5 can be fitted onto the neck of the infusion bottle, and the needle limiting ring 4 can be fitted onto the connection between the bottle stopper puncturist and the air inlet tube of the infusion tube, as in the prior art, Chinese utility model patent, authorized announcement number CN221808292U;

[0044] In this embodiment, the device can constrain the relative position between the stopper puncturer of the infusion tubing and the neck of the infusion bottle, making it more difficult for the stopper puncturer to break free from the infusion bottle.

[0045] In another embodiment of this application, such as Figures 1 to 5 As shown, the limiting ring 1, the needle limiting ring 4, and the bottle limiting ring 5 are all made of nylon; the first connecting strip 2, the limiting groove 21, and the second connecting strip 3 are all made of plastic.

[0046] In this embodiment, the limiting ring, needle limiting ring, and bottle limiting ring are made of nylon, which has the advantages of high strength, light weight, and good wear resistance. The first connecting strip, limiting groove, and second connecting strip are made of plastic, which can have stronger support and tensile strength.

[0047] In the above embodiments, further, as shown... Figure 1 and Figure 2 As shown, the limiting ring 1 and the first connecting strip 2, and the second connecting strip 3 and the needle limiting ring 4 and the bottle limiting ring 5 are all sewn together;

[0048] In this embodiment, a sewing method is used to connect the limiting ring to the first connecting strip, and the second connecting strip to the needle limiting ring and the bottle limiting ring, thereby ensuring the firmness of the connection and further improving the overall tensile strength of the restraint device.

[0049] In the above embodiments, further, as shown... Figures 2 to 5 As shown, along the width direction of the second connecting strip 3, a plurality of second one-way locking teeth 32 are provided on both sides of the second connecting strip 3, and a plurality of second tooth grooves 212 adapted to the second one-way locking teeth 32 are provided on both sides inside the limiting groove 21.

[0050] In this embodiment, one-way locking teeth are provided on three sides of the second connecting strip, so that it can be engaged with the limiting groove on the first connecting strip on three sides. This greatly reduces the degree of relative displacement between the first and second connecting strips after engagement, improves structural stability, and enhances the interlocking force.

[0051] In another embodiment of this application, such as Figures 1 to 3 and Figure 5 As shown, the end of the second connecting strip 3 near the limiting groove 21 has a rounded corner wedge structure design;

[0052] In this embodiment, the end of the second connecting strip adopts a rounded wedge structure design, which makes the second connecting strip more directional when inserted into the limiting groove on the first connecting strip, and facilitates the smooth insertion of the second connecting strip into the limiting groove to achieve a snap-fit.

[0053] In the above embodiments, further, as shown... Figures 1 to 3 and Figure 5 As shown, the end of the first connecting strip 2 near the limiting groove 21 has a rounded corner wedge structure design;

[0054] In this embodiment, the end of the first connecting strip adopts a rounded wedge structure design, which makes it less likely to scratch people's skin and improves safety.

[0055] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
