[0002] Intravenous infusion is a routine nursing technical operation that clinical nurses must master and is one of the most common operations in daily nursing work. Performing good intravenous infusion can inject a large amount of liquid, electrolytes or blood into the human body through a vein, playing a therapeutic role.
[0003] In clinical use, during a long-term infusion process, patients may become agitated, or there may be some uncooperative patients. Or, due to accidentally large limb movements, the plastic needle of the infusion set may be pulled out from the infusion bottle (bag), which can lead to adverse consequences such as infusion interruption, blood backflow in the infusion tube, and contamination of the pipeline. In the past, in such cases, medical staff would use tape to wrap the structural parts of the infusion set and the infusion bottle (bag), but the effect was not ideal and it increased the cumbersome procedures. Summary of the Utility Model
[0004] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. In this part, as well as in the abstract of the specification and the title of the utility model of this application, some simplifications or omissions may be made to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.
[0005] Therefore, the purpose of the utility model is to provide an anti-slip and anti-disengagement auxiliary device for an infusion set to solve the problem that during clinical use, during a long-term infusion process, patients may become agitated, or there may be some uncooperative patients, or due to accidentally large limb movements, the plastic needle of the infusion set may be pulled out from the infusion bottle (bag) as mentioned in the above background art.
[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-slip and anti-disengagement auxiliary device for an infusion set, which includes a cylindrical sleeve. The sleeve is formed by the clamping of a first semi-circular tube and a second semi-circular tube. A torsion spring hinge shaft is connected to the junction side of the first semi-circular tube and the second semi-circular tube. The top of the sleeve has an upper end plate, and the middle part of the upper end plate has a first limiting hole. The bottom of the sleeve has a lower end plate, and the middle part of the lower end plate has a second limiting hole. Inside the upper end plate, there is an infusion nozzle clamped in the first limiting hole. A rubber plug at the end of the infusion nozzle is inserted with a plastic needle. A needle seat is provided around the bottom of the plastic needle. Inside the sleeve and above the second limiting hole, there are a plurality of limiting supports for supporting the needle seat.
[0007] As a preferred embodiment of the anti-slip and anti-disengagement auxiliary device for an infusion set of the present utility model, a circumferential annular protrusion with a diameter larger than the inner diameter of the first limiting hole is further provided on the periphery of the infusion nozzle, and an infusion hose is provided at the bottom of the needle holder, which is communicated with the plastic needle and the lower part of which passes through the inside of the second limiting hole.
[0008] As a preferred embodiment of the anti-slip and anti-disengagement auxiliary device for an infusion set of the present utility model, an avoidance hole is provided at the center of the limiting support, and the diameter of the avoidance hole is smaller than the outer diameter of the needle holder;
[0009] The distance from the top of the limiting support to the infusion nozzle is smaller than the length of the plastic needle.
[0010] As a preferred embodiment of the anti-slip and anti-disengagement auxiliary device for an infusion set of the present utility model, an auxiliary elastic sheet is fixed on the inner radial circumference of the sleeve and is located above the limiting support and below the needle holder.
[0011] As a preferred embodiment of the anti-slip and anti-disengagement auxiliary device for an infusion set of the present utility model, ear plates are respectively fixed on the outer sides of the first semi-circular tube and the second semi-circular tube, and the ear plates are respectively located on both sides of the torsion spring hinge shaft.
[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: for the anti-slip and anti-disengagement auxiliary device of the infusion set, during use, first insert the plastic needle into the rubber stopper of the infusion nozzle, and lock the connection part of the infusion nozzle and the infusion set through the sleeve. When a downward pulling force is applied to the infusion hose, the auxiliary elastic sheet can form an elastic reverse support for the needle holder and the plastic needle, and prevent the plastic needle from slipping out of the infusion nozzle too much, playing a role of buffering and stabilizing. When the pulling force is too large, the needle holder will break free from the restraint of the auxiliary elastic sheet and then be supported and stabilized by the limiting support, avoiding the complete detachment of the needle from the infusion nozzle, and the infusion passage still remains in a flowing state, effectively avoiding the comprehensive adverse consequences caused by the infusion set being pulled out. The operation is simple and the positioning effect is better. Description of the Drawings

Detailed implementation manners
[0017] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.
[0018] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When detailing the implementation manners of the present utility model, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present utility model here. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.
[0019] To make the purpose, technical solution and advantages of the present utility model clearer, the following will further describe in detail the implementation manners of the present utility model with reference to the accompanying drawings.
[0020] Figures 1 - 3 Shown is the overall structural schematic diagram of an anti-slip and anti-detachment auxiliary device of an infusion set of the present utility model. Please refer to Figures 1 - 3 An anti-slip and anti-detachment auxiliary device of an infusion set in this implementation manner includes a cylindrical sleeve 10, which is formed by the first semi-circular tube 101 and the second semi-circular tube 102 being clamped together. On one side of the junction of the first semi-circular tube 101 and the second semi-circular tube 102, there is a torsion spring hinge shaft 105. The top of the sleeve 10 has an upper end plate 103, and in the middle of the upper end plate 103, there is a first limiting hole 103a. The bottom of the sleeve 10 has a lower end plate 104, and in the middle of the lower end plate 104, there is a second limiting hole 104a. Inside the upper end plate 103, there is an infusion nozzle 20 clamped in the first limiting hole 103a. A plastic needle 30 is inserted into the rubber stopper at the end of the infusion nozzle 20. At the bottom of the plastic needle 30, there is a needle base 301 in a circle. Inside the sleeve 10 in a circle and above the second limiting hole 104a, there are a plurality of limiting supports 40 for supporting the needle base 301.
[0021] The infusion nozzle 20 is also provided with an annular protrusion 201 with a diameter larger than the inner diameter of the limiting hole 103a. The bottom of the needle seat 301 is provided with an infusion hose 31 which is connected to the plastic needle 30 and the lower part is passed through the inner side of the limiting hole 104a. It should be noted that conventional infusion bottles / bags have an annular protrusion 201 at the position of the infusion nozzle 20, and the root of the conventional plastic needle 30 has a needle seat 301. Therefore, the present implementation device makes full use of the structure of the existing infusion device and the infusion bottle / bag for matching design, making it clearer and simpler to use.
[0022] The limiting support 40 has an avoidance hole in the center, and the diameter of the avoidance hole is smaller than the outer diameter of the needle seat 301; wherein, the distance between the top of the limiting support 40 and the infusion nozzle 20 is smaller than the length of the plastic needle 30. The purpose of such design is that even if the plastic needle 30 is pulled to the lowest point, under the obstruction of the limiting support 40, the needle tip of the plastic needle 30 will not separate from the inner side of the infusion nozzle 20, thereby ensuring the smoothness of the infusion.
[0023] An auxiliary spring piece 50 is fixed radially inside the sleeve 10 and is located above the limit support 40 and below the needle seat 301 ; ear plates 60 are fixed to the outside of the first semicircular tube 101 and the second semicircular tube 102 , and the ear plates 60 are located on both sides of the torsion spring hinge shaft 105 . When in actual use, the plastic needle 30 is first inserted into the rubber plug of the infusion nozzle 20, and then the ear plate 60 is pressed left and right to open the sleeve 10. After determining the position, the ear plate 60 is loosened, so that the infusion nozzle 20 is embedded in the inner side of the limiting hole 103a, and the sleeve 10 is firmly hung on the infusion bottle / bag. When the infusion hose 31 is subjected to a downward pulling force, the auxiliary spring piece 50 can form an elastic reverse support for the needle seat 301 and the plastic needle 30, and prevent the plastic needle 30 from slipping off the infusion nozzle 20 too much, playing a buffering and stabilizing role. When the pulling force is too large, the needle seat 301 will break free from the restraint of the auxiliary spring piece 50, and then be supported and stabilized by the limiting support 40, thereby preventing the needle from completely separating from the infusion nozzle 20, and the infusion passage still remains in a flowing state, effectively avoiding the comprehensive adverse consequences caused by the infusion set being pulled out, simple operation, and better positioning effect.
[0024] Furthermore, the anti-slip auxiliary device is also very convenient to disassemble. It only needs to press the ear plates 60 on both sides to open the sleeve 10, so that the connection part between the infusion nozzle 20 and the infusion set can be unlocked.
[0025] In summary, for the anti-slip auxiliary device of an infusion set according to this embodiment, during use, first insert the plastic needle 30 into the rubber stopper of the infusion nozzle 20, then press the ear plates 60 left and right to open the sleeve 10. After determining the position, release the ear plates 60 so that the infusion nozzle 20 is stuck inside the first limiting hole 103a. In this way, the sleeve 10 is firmly hung on the infusion bottle / bag. When the infusion hose 31 is subjected to a downward pulling force, the auxiliary elastic piece 50 can form an elastic reverse support for the needle seat 301 and the plastic needle 30, and prevent the plastic needle 30 from slipping out of the infusion nozzle 20 too much, playing a role of buffering and stabilizing. When the pulling force is too large, the needle seat 301 will break free from the restraint of the auxiliary elastic piece 50 and then be supported and stabilized by the limiting support 40, avoiding the complete detachment of the needle from the infusion nozzle 20, and the infusion passage still remains in a flowing state.
[0026] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
