Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

In view of the phenomenon that the transfusion system is separated from the transfusion bag due to the movement of the patient or the careless pulling in the clinical practice, as shown in fig. 1, the utility model provides a disposable transfusion system capable of fixing the transfusion bag, which comprises a bottle stopper puncture outfit 10 and a transfusion tube 11 with an upper end cover arranged at the lower end of the bottle stopper puncture outfit, the middle part of the bottle stopper puncture outfit 10 is provided with a stop ring 12 convenient for the medical staff to puncture. A sleeve 13 extending downwards is arranged on the bottom surface of the stopper ring 12, the diameter of the sleeve 13 is larger than the outer diameter of the infusion tube 11 and smaller than the outer diameter of the stopper ring 12, so that an annular accommodating cavity for accommodating the upper end of the infusion tube 11 is formed between the sleeve 13 and the bottle stopper puncture device 10, and when the upper end of the infusion tube 11 is sleeved on the lower end of the bottle stopper puncture device 10, the upper part of the infusion tube 11 is accommodated in the accommodating groove in the whole body.

In order to fix the infusion bag 2 and the infusion apparatus to prevent the infusion apparatus from falling off, an infusion bag fixing device is further disposed on the infusion apparatus, and as shown in fig. 2, the infusion bag fixing device includes a cylindrical moving head 30 and a plurality of retractable holding claws 31 disposed along a circumferential direction of the moving head 30. The center of the moving head 30 is provided with a through hole 300, the inner diameter of the through hole 300 is larger than the outer diameter of the sleeve 13 and smaller than the outer diameter of the stop ring 12, the arrangement can prevent the bottle stopper puncture outfit 10 from moving downwards and being separated from the infusion bag 2 when the infusion tube is pulled accidentally, and the sleeve 13 is arranged in the through hole 300 in a penetrating way so that the moving head 30 can move up and down on the sleeve 13. The grip jaw 31 includes a support rod 310 hinged to the moving head 30 and a grip bar 311 hinged to the support rod 310. In the present embodiment, three receiving grooves 301 are formed on the sidewall of the moving head 30 along the circumferential direction thereof at equal intervals for receiving the bottom ends of the supporting rods, and the bottom ends of the three supporting rods 310 are correspondingly disposed in the three receiving grooves 301. The bottom of the support rod 310 is provided with a radial hole, the moving head 30 is also provided with a hole along the circumference, and the fixing rope passes through the radial holes at the bottom of the three support rods 310 and the hole along the circumference of the moving head 30 so as to hinge the three holding claws 31 and the moving head 30 together. In order to improve the gripping degree of the gripping claws 31, the gripping rods 311 are further connected with the moving head 30 through springs 32, that is, one end of each spring 32 is fixed in the middle of the gripping rod 311, and the other end of each spring 32 is fixed at the top of the moving head 30, so that when the moving head 30 is pushed downwards, the moving head 30 drives the plurality of gripping claws 31 to move downwards, the three gripping claws 31 are gradually folded under the action of the springs 32, and the gripping rods 311 on the three gripping claws 31 tightly grip the infusion bag 2; when the moving head 30 is pushed upwards, the three gripping claws 31 are spread apart to release the infusion bag 2. In order to prevent the holding claws 31 from being easily released when holding the infusion bag 2, the outer wall of the sleeve 13 is further provided with a limiting device for limiting the upward movement of the holding claws 31 when being folded. The limiting device comprises two elastic limiting pieces 40 symmetrically arranged on the outer wall of the sleeve 13, the upper ends of the elastic limiting pieces 40 are fixed on the outer wall of the lower part of the sleeve 13, and the lower ends of the elastic limiting pieces 40 are free ends and extend outwards. The angle between the elastic limiting piece 40 and the axis of the sleeve 13 is set to be 15-30 degrees, and at this angle, the moving head 30 can not only easily get over the elastic limiting piece 40, but also can well prevent the moving head 30 from moving upwards after the moving head 30 gets over, so as to prevent the holding claw 31 from loosening. In addition, the spring 32 is in a stretched state after the moving head 30 passes over the elastic stopper 40.

In the disposable infusion apparatus capable of fixing the infusion bag, the infusion bag 2 is hung on the infusion support, the upper half part of the bottle stopper puncture outfit 10 on the infusion apparatus is punctured into the infusion bag 2, then the moving head 30 is pushed downwards, the moving head 30 drives the three holding claws 31 on the moving head to move downwards in the downward movement process, the holding rods 311 on the three holding claws 31 are gradually folded under the action of the spring 32 to tightly hold and clamp the infusion bag 2, when the moving head 30 moves to the elastic limiting sheet 40, the moving head 30 presses the elastic limiting sheet 40 towards the direction close to the infusion tube 11, as the elastic limiting sheet 40 has elasticity, the elastic limiting sheet is gradually extruded and attached to the outer wall of the sleeve 13, and then the moving head 30 passes over the elastic limiting sheet 40, at the moment, the holding rods 311 on the holding claws 31 are folded to tightly hold the infusion bag 2, and then the moving head 30 is not moved any more, at the moment, the movable head 30 is limited by the elastic limiting sheet 40 on the sleeve 13 and cannot move downwards, and the three holding claws 31 on the movable head 30 tightly clamp the infusion bag 2, as shown in fig. 3, so that even if a patient moves to a certain extent or accidentally pulls the infusion apparatus, the infusion apparatus cannot be easily separated from the infusion bag 2; after the infusion is finished, the moving head 30 is pushed downwards slightly, then the elastic limiting sheet 40 is pressed towards the direction close to the infusion tube 11, the elastic limiting sheet 40 is extruded and attached to the outer wall of the sleeve 13, the moving head 30 is pushed upwards at the moment, the moving head 30 penetrates through the elastic limiting sheet 40 to move upwards, the holding rods 311 on the three holding claws 31 are gradually expanded, the holding claws 31 release the infusion bag 2, and the infusion apparatus is pulled out from the infusion bag 2.

While the foregoing is directed to the preferred embodiment of the present invention, it will be understood that the invention is not limited thereto, and that various modifications and changes can be made by those skilled in the art without departing from the principles of the invention.
