For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0026] Specific embodiments, as shown, for the preferred embodiment of the present application. A portable infusion auxiliary device, mainly including the casing 1, the casing 1 inside the flow type peristaltic pump is installed, the front of the casing 1 is provided with the adjusting knob 2 for adjusting the peristaltic pump, the pump cover 3 of the peristaltic pump can be detachably installed on the front of the casing 1;The back of the casing 1 is detachably installed with the clamping seat, the clamping seat mainly includes the bottom plate 14, the clamping block 4, the bottom plate 14 is provided with the clamping block 4 on the plate surface, the clamping block 4 is provided with the bayonet, the length direction of the bottom plate 14 both sides are provided with the plate hole, the back of the casing 1 is provided with the fixed hole 16, the plate hole is inserted with the connecting screw 15, the nail end of the connecting screw 15 is screwed with the fixed hole 16 through the plate hole, the clamping block 4 is provided with the clamping hole, the axis of the clamping hole is parallel with the axis of the plate hole, the clamping hole is screwed with the fixed stud 18;The side of the casing 1 is installed with the liquid level sensor 11, the sensing port of the liquid level sensor 11 is perpendicular to the side of the casing 1 and outward, the top end of the casing 1 is installed with the lifting rod 5, the end of the lifting rod 5 is installed with the hook for hanging the infusion container, the hook and the liquid level sensor 11 are located on the same side of the casing 1;The side of the casing 1 is provided with a plurality of insertion holes 10, a plurality of insertion holes 10 are arranged along the vertical direction, one of the insertion holes 10 is detachably inserted with the anti-drop clamp 7, the anti-drop clamp 7 is provided with the insertion rod 9, the insertion rod 9 is inserted in one of the insertion holes 10, and the anti-drop clamp 7 is clamped on the bottle plug penetrator 8.
[0027] In practical implementation, the device housing 1 is first secured in a suitable position using a mounting bracket, and then fixed in place with a fixing stud 18. For example, the device housing 1 can be attached to the side rails of the hospital bed, with the fixing stud 18 abutting against the rails within the mounting slot, thus fixing the device housing 1 to the rails. Because the rails are raised when the patient is lying in bed, the patient's hands will be close to the side rails. With the device housing 1 fixed to the rails, the infusion bottle 6 or infusion bag is hung on the hook of the lifting rod 5 on the device housing 1, shortening the distance between the hand and the infusion bottle 6 or infusion bag. Therefore, the infusion tube 12 will not be taut, and when the patient's hand moves, it is less likely to pull the infusion tube 12, causing the bottle stopper puncturist 8 at the end of the infusion tube 12 to detach from the infusion bottle 6. When the bed rails need to be raised and lowered frequently during the day, the device housing 1 can be installed on the headboard or footboard without affecting the raising and lowering of the rails. Furthermore, the casing 1 is installed low on the bed rail, headboard, or footboard, allowing the patient or medical staff to easily remove and carry it when the patient needs to get out of bed. Because this application uses a peristaltic pump inside the casing 1 to assist with infusion, the patient does not need to hold the infusion bottle 6 high or hold the infusion pole as usual when getting out of bed. The patient or family member can simply hold the casing 1 and get out of bed without affecting the infusion. To reduce the weight of this invention, a miniature flow-type peristaltic pump is used, and the pump has an adjustment knob 2 to adjust the infusion rate, making it convenient for patients who require controlled infusion rates. This peristaltic pump is an existing structure and will not be described in detail here. Once the casing 1 is secured, medical staff suspend the infusion bottle 6 on the hook on the lifting rod 5. After completing the infusion procedure for the patient, the medical staff opens the pump cover 3 on the surface of the casing 1 and inserts the infusion tube 12 into the peristaltic pump, using the peristaltic pump to assist the infusion. At this time, with the stopper of the infusion bottle 6 facing downwards, the medical staff adjusts the height of the lifting rod 5 so that the warning line for the liquid level at the bottom of the infusion bottle 6 or infusion bag is aligned with the sensing port of the liquid level sensor 11 on the side of the casing 1, and then secures the lifting rod 5. When the liquid level drops to the warning line, the liquid level sensor 11 detects this and triggers an alarm, reminding the patient that the infusion is about to end. The patient can then promptly notify the medical staff, protecting their health and reducing the workload of the medical staff. After the lifting rod 5 is fixed in position, medical staff use the anti-dislodgement clamp 7 to hold the bottle stopper puncture device 8, and then insert the insertion rod 9 on the anti-dislodgement clamp 7 into the appropriate insertion hole 10 on the side of the machine housing 1. The insertion rod 9 and the insertion hole 10 limit the anti-dislodgement clamp 7 to achieve the effect of preventing dislodgement. Since most bottle stopper puncture devices 8 have a limiting ring, the anti-dislodgement clamp 7 can be clamped below the limiting ring. When the infusion tube 12 is pulled, the bottle stopper puncture device 8 is not easy to slip off under the limitation of the anti-dislodgement clamp 7.Because the anti-falling clamp 7 is fixed on the machine shell 1, the infusion bottle 6 is hung on the hook of the lifting rod 5 on the machine shell 1, when the patient moves off the bed, the utility model can also achieve the effect of preventing falling. Further, the clamping surface of the anti-falling clamp 7 is provided with an anti-skid pad, so that the clamping is more stable.
[0028] Because sometimes, the utility model needs to be fixed on the side of the infusion rod or the bedside board, that is, the opening of the clamping opening of the clamping block 4 needs to face the horizontal direction, instead of downward. In order to make the lifting rod 5 always face upward after the machine shell 1 is fixed, further, the back of the machine shell 1 is provided with two groups of fixing holes 16, one group of fixing holes 16 is arranged along the vertical direction, and the other group of fixing holes 16 is arranged along the horizontal direction, the plate hole on the bottom plate 14 is connected with one group of fixing holes 16 through the connecting screw 15 each time. When the machine shell 1 is clamped on the upper end surface of the guardrail, the bedside board, the tailboard and the like, the opening of the clamping opening faces downward, at this time, the plate hole on the bottom plate 14 is connected with the group of fixing holes 16 along the horizontal direction. When the machine shell 1 is clamped on the side of the infusion rod, the bedside board or the tailboard and the like, the opening of the clamping opening faces the horizontal direction, at this time, the plate hole on the bottom plate 14 is connected with the group of fixing holes 16 along the vertical direction. The installation direction of the clamping seat can be convenient for installation in different positions.
[0029] Because the installation position of the shell 1 is different, the clamping surface of the card seat can be a plane or a round rod. In order to better fix the shell 1, further, the two ends of the fixing screw 18 are respectively connected with the first clamping plate 17 and the second clamping plate 13; the first clamping plate 17 is a flat plate, the second clamping plate 13 is an arc-shaped plate, the arc-shaped opening of the arc-shaped plate faces away from the fixing screw 18, the first end of the fixing screw 18 is a smooth rod, the second end of the fixing screw 18 is a threaded rod, one end of the smooth rod of the fixing screw is located in the card mouth; the surface of the first clamping plate 17 is vertically provided with a sleeve, the sleeve is provided with an internal thread, the sleeve is rotatably connected with the first end of the fixing screw 18, the sleeve is threadedly connected with the second end of the fixing screw 18, and the sleeve is not simultaneously connected with the first end and the second end of the fixing screw 18; the outer surface of the second clamping plate 13 is vertically provided with a connecting cylinder, the connecting cylinder is provided with an internal thread, the connecting cylinder is rotatably connected with the first end of the fixing screw 18, the connecting cylinder is threadedly connected with the second end of the fixing screw 18, and the connecting cylinder is not simultaneously connected with the first end and the second end of the fixing screw 18. When the card mouth of the clamping block 4 is clamped on the plane, the first end of the fixing screw 18 in the card mouth is rotatably connected with the first clamping plate 17, the second end of the fixing screw 18 is threadedly connected with the second clamping plate 13, the fixing screw 18 is rotated through the second clamping plate 13, so that the first clamping plate 17 is clamped on the fixed plane. When the card mouth of the clamping block 4 is clamped on the round rod, the first end of the fixing screw 18 in the card mouth is rotatably connected with the second clamping plate 13, the second end of the fixing screw 18 is threadedly connected with the first clamping plate 17, the fixing screw 18 is rotated through the first clamping plate 17, so that the arc-shaped second clamping plate 13 is in abutment with the round rod and is fixed, and the contact area is increased, so that the fixing is more stable. When the utility model is not used, the fixing screw 18 is screwed, so that the first end of the fixing screw 18 is connected with the first clamping plate 17 or the second clamping plate 13 and is in abutment with the inner side wall of the clamping block 4, so that the first clamping plate 17 or the second clamping plate 13 is connected with the fixing screw 18, and will not fall off. Further, the surface of the first clamping plate 17 and the inner surface of the second clamping plate 13 are provided with anti-skid pads, the friction is increased through the anti-skid pads, and the fixing is more stable.
[0030] Further, the head end of the connecting screw 15 is flush with the bottom surface of the card mouth of the clamping block 4, the bottom surface refers to the surface close to the bottom plate 14, so that when the card mouth is clamped on the plane or the round rod, the connecting screw 15 will not affect the fixing of the card seat.
[0031] The above description is a detailed description of the preferred and feasible embodiment of the utility model, but the embodiment is not used to limit the patent application range of the utility model, and any equivalent change or modification change completed under the technical spirit of the utility model should belong to the patent range covered by the utility model.
