[0038] Based on the above problems in the prior art, the utility model provides a kind of anti-disengagement infusion assembly, as shown in Figure 1 And Figure 3 As shown, the anti-disengagement infusion assembly comprises: an infusion tube, the infusion tube comprises a puncture device 100, the puncture device 100 comprises a wing 120 vertically and symmetrically arranged on both sides of a puncture tube 110;A bottle body 200, a sealing plug 210 is arranged at the bottle opening position of the bottle body 200;A cap body 300, the cap body 300 is fixedly connected with the bottle opening, the cap body 300 is provided with a mounting plate 310, the mounting plate 310 is provided with a mounting hole 311 at the center position corresponding to the sealing plug 210, the shape of the mounting hole 311 is matched with the shape of the wing 120, the mounting plate 310 is arranged at a predetermined distance from the sealing plug 210, and the wing 120 is detachably clamped in the cavity between the mounting plate 310 and the sealing plug 210.

[0039] The utility model discloses a mounting hole 311 is provided with mounting plate 310 on cap body 300, when cap body 300 is combined with bottle body 200, and the cavity is formed between mounting plate 310 and sealing plug 210 of bottle body 200, when combined with infusion tube, the wing 120 of infusion tube puncture ware 100 can pass through mounting hole 311 and rotate and form the engagement with mounting plate 310, can prevent the connecting part of infusion tube and liquid medicine bottle from falling off in the infusion process, improves infusion stability.

[0040] In the above embodiment, as shown in Figure 1 The main body of the anti-falling infusion assembly includes an infusion tube, a bottle body 200 and a cap body 300, which is also the main instrument for infusion treatment in the prior art. Unlike the prior art, the cap body 300 fixed on the bottle body 200 is improved in the utility model. Specifically, in the infusion tube, the infusion needle for puncturing the skin of the patient, the regulator for adjusting the infusion speed, and the Murphy drip tube for displaying the infusion speed are included in the prior art. The important component connected with the medicine bottle in the prior art is the puncture device 100. In the present embodiment, the main components used by the anti-falling infusion assembly include the puncture device 100. The puncture device 100 includes wings 120 vertically and symmetrically arranged on both sides of the puncture tube 110. When connected with the medicine bottle of the prior art, the puncture tube 110 passes through the bottle opening of the medicine bottle and delivers the liquid medicine through the pipeline.

[0041] The bottle body 200 has the same main function as the medicine bottle in the prior art, which is used to hold liquid medicine. A sealing plug 210 is arranged at the bottle opening position of the bottle body 200 to ensure that the liquid medicine is sealed in the bottle body 200, so as to facilitate the hanging and protection of the liquid medicine. When connected with the infusion tube, the puncture tube 110 of the puncture device 100 penetrates the sealing plug 210 and enters the bottle body 200, and is limited by the wings 120 on both sides to achieve connection and fixation by friction force.

[0042] In the present embodiment, the biggest difference from the prior art is the cap body 300. The cap body 300 is fixedly connected with the bottle opening of the bottle body 200 to prevent the sealing plug 210 from falling off. An installation plate 310 is arranged on the cap body 300.

In actual arrangement, the shape of the installation hole 311 is matched with the shape of the wing 120 of the puncture device 100, and the installation plate 310 is arranged at a predetermined distance from the sealing plug 210. Therefore, in the present embodiment, when the anti-falling infusion assembly is installed, as shown in Figure 3 and Figure 4As shown, the clamping and fixing of the puncture device 100 and the cap 300 and the bottle 200 can be achieved by inserting the puncture device 100 through the installation hole 311 into the sealing plug 210, and then rotating the puncture device 100 so that the flaps 120 of the puncture device 100 are clamped in the cavity between the installation plate 310 and the sealing plug 210. When the infusion tube is pulled by external force, the puncture device 100 will not be separated from the sealing plug 210 due to the pulling force, thereby effectively ensuring the stability of the connection between the infusion tube and the bottle 200 during the infusion process.

[0043] Specifically, as Figure 1 shown, since there is a cavity between the installation plate 310 of the cap 300 and the sealing plug 210 of the bottle 200, in order to avoid the situation that the puncture device 100 is not stably installed due to air pressure, sealing plug 210 part tolerance and other problems, in the embodiment, an extension part 211 clamped on the upper surface of the bottle mouth is actually provided when the sealing plug 210 is installed. The diameter size of the extension part 211 is adapted to the diameter size of the outside of the bottle mouth, which can limit the installation position of the sealing plug 210 and facilitate the disassembly of the sealing plug 210 by medical staff. Correspondingly, as Figure 2 shown, a limiting ring 320 is further arranged on one side of the installation plate 310 of the cap 300. The limiting ring 320 is fixedly arranged inside the cap 300. When the cap 300 is installed at a predetermined position on the bottle 200, the upper side of the extension part 211 of the sealing plug 210 is abutted by the limiting ring 320, that is, the cap 300 can achieve the effect of fixing the installation position of the sealing plug 210 on the bottle 200. On the other hand, the distance size between the limiting ring 320 and the installation plate 310 is adapted to the thickness size of the above-mentioned flaps 120, so that a cavity with a fixed size is formed between the limiting ring 320 and the installation plate 310 for clamping the flaps 120. That is, when the infusion tube is installed on the cap 300, the flaps 120 are clamped at the position between the limiting ring 320 and the installation plate 310, which can ensure the stability of the clamping of the flaps 120.

[0044] In an embodiment of the present application, as Figure 1As shown, in the specific prefabricated medicine bottle, the bottle body 200 and the cap body 300 are prefabricated and fixedly connected, the outer side of the bottle mouth is protrusively arranged on the bottle body, and correspondingly, the mounting ring 330 is arranged on one side of the limiting ring 320 of the cap body 300, the distance between the mounting ring 330 and the limiting ring 320 is matched with the height of the bottle mouth, when prefabricating, the cap body 300 is sleeved on the outer side of the bottle mouth, the lower end surface of the protrusively arranged part of the bottle mouth abuts against the mounting ring 330, the upper end surface of the protrusively arranged part of the bottle mouth corresponds to the limiting ring 320, and the limiting ring 320 abuts against the extending part 211 of the sealing plug 210, so that the cap body 300 is fixedly installed on the bottle body 200, and the cap body 300 is prevented from being separated from the bottle body 200 during storage, transportation and use, so that the hygiene and safety of the bottle mouth are ensured.

[0045] Further, as shown in the prefabricated medicine bottle, Figure 1 In order to protect the lower sealing plug 210 of the cap body 300 and avoid that the sealing plug 210 is contaminated by bacteria, dust and the like and affects the treatment effect, a dustproof plate 340 is arranged on one side of the mounting plate 310 of the cap body 300 in the embodiment, the dustproof plate 340 is located on the side of the mounting plate 310 away from the limiting ring 320, a plurality of connecting points 341 are annularly arranged on the dustproof plate 340, the dustproof plate 340 is fixedly connected with the inner wall of the cap body 300 through the connecting points 341, and the mounting hole 311 of the mounting plate 310 is shielded, a pull ring is further arranged on the dustproof plate 340, when the bottle body 200 is in a storage state, the dustproof plate 340 on the cap body 300 can achieve the effects of dustproof and stainproof, when the bottle body 200 needs to be combined with the infusion tube, medical staff can manually pull the pull ring, the connecting points 341 are broken due to stress concentration, and the dustproof plate 340 can be detached from the cap body 300, and the mounting hole 311 is exposed to be used for dispensing medicine and mounting the infusion tube.

[0046] In another embodiment of the utility model, as shown in the prefabricated medicine bottle, Figure 1As shown, since there is a situation of unsmooth infusion caused by the air pressure problem of the bottle 200 when the infusion treatment is carried out, in view of this situation, the anti-disengagement infusion assembly in the embodiment further comprises an air passage member 400, which specifically comprises an air needle 410. Correspondingly, a ventilation hole 312 is arranged at a position corresponding to one side of the mounting hole 311 on the mounting plate 310, and the diameter size of the ventilation hole 312 is greater than that of the air needle 410. In actual use, when there is an unsmooth infusion situation, the medical staff can penetrate the air needle 410 of the air passage member 400 along the ventilation hole 312 to pass through the sealing plug 210, so that the inside of the bottle 200 is in communication with the outside. When the infusion is carried out, the air pressure in the bottle 200 is reduced after the medicinal liquid in the infusion tube flows out, and at this time, the air is sucked into the bottle 200 through the external air pressure difference along the air needle 410, so as to maintain the air pressure balance, and the effect of more smooth infusion treatment can be achieved.

[0047] Further, in the embodiment, in order to limit the installation position of the air needle 410, as shown in the drawings, Figure 5 an annular clamping ring 420 is further arranged outside the air needle 410, and the diameter size of the annular clamping ring 420 is greater than that of the air needle 410. When the air passage member 400 is installed on the cap 300, the annular clamping ring 420 abuts against the mounting plate 310, so as to limit the installation position of the air needle 410 and guarantee the stability of the installation of the air needle 410.

[0048] More specifically, in the embodiment, as shown in the drawings, Figure 5 the air passage member 400 specifically further comprises an exhaust pipe 430 and an exhaust valve 440 which are arranged in communication with the air needle 410. The exhaust pipe 430 is used for guiding the flow of gas, and the exhaust valve 440 plays a role of filtering the gas. A filter piece is embedded in the inside of the exhaust valve 440, and a plurality of exhaust holes 441 are arranged outside the exhaust valve 440. The air enters the exhaust valve 440 through the exhaust holes 441, is filtered by the filter piece and then enters the exhaust pipe 430, and finally enters the bottle 200 through the air needle 410, so as to avoid that the air entering the bottle 200 contains dust or bacteria and protect the use safety of the medicinal liquid.

In this embodiment, the vent 312 and the medication addition hole 313 are preferably located on the same side of the mounting plate 310 and within one half of the mounting plate 310. The purpose of this is that, since the flap 120 may be touched by medical staff during the installation of the infusion tube, resulting in the presence of bacteria, the rotation direction of the flap 120 should avoid contact with the area where the medication addition hole 313 and the vent 312 are located during actual use, thereby ensuring the hygiene of the infusion. In the above embodiments, the cap 300 can be pre-installed on the bottle 200 for use as storage for specific drugs. When performing infusion therapy, medical staff only need to open the dust cover 340 to use it, which is simple and convenient.

[0050] In another possible embodiment of this utility model, such as Figure 6 As shown, since the main function of the bottle 200 in this embodiment is to hold the medicine during intravenous infusion, and the bottle 200 needs to be used upside down during intravenous infusion, a receiving groove 230 is provided at the bottom of the bottle 200 to facilitate hanging the bottle 200. A hanging ring 231 is provided inside the receiving groove 230. One end of the hanging ring 231 is fixedly connected to the bottle 200, and its shape is adapted to the shape of the receiving groove 230. The hanging ring 231 is made of elastic material.
