[0002] At present, the infusion operations in the hospital wards all use common infusion stands. Although multiple bottles of liquid
medicine can be hung on each shelf, the bottles must be changed by a nurse, and the patient or family member needs to be taken care of. Informing the nurse to change the bottle, this process consumes a lot of manpower and time, especially in large hospitals with many wards, the infusion bottle change takes a lot of time and energy for the nurses, for this reason,
Chinese patent CN109771731A discloses an automatic patient infusion bottle changer The bottle device includes a fixing seat, grooves distributed equidistantly on the outer wall of the top of the fixing seat, and an infusion bottle is placed on the inner wall of the groove, and a bearing is welded on the inner wall of the bottom of the fixing seat, and the bearing The inner wall of the
drive shaft is rotatably connected with a
drive shaft, the outer wall of the
drive shaft is welded with a driving
sprocket, the outer wall of the drive
sprocket is connected with a drive chain, and the drive chain is driven on the inner wall of the side away from the drive
sprocket. The driven sprocket is connected, and the outer wall of the transmission chain is welded with equidistantly distributed blocks, and the outer wall of one end of the transmission shaft is welded with a
coupling, and the outer wall of the end of the
coupling away from the transmission shaft is welded There is a driving motor, a bottom plate is welded on one side of the outer wall of the driving motor, a clamping seat is bonded to the bottom of the outer wall of the infusion bottle, a hole is opened on the outer wall of the bottom of the infusion bottle, and the inner wall of the hole is passed through a rubber A needle tube is inserted into the plug, and an I-shaped clamping block is welded on the outer wall of the end of the needle tube away from the infusion bottle. A mechanical clamp is clamped on one side of the I-shaped clamping block, and a mechanical clamp is clamped on one side of the mechanical clamp. A connecting rod is welded on the top, and an electromagnetic telescopic rod is welded on the outer wall of the connecting rod away from the mechanical clamp. A flow sensor is bonded to the outer wall of the needle tube away from the I-shaped clamping block, and the flow sensor passes through The conduit communicates with the inner wall of the needle tube. The disadvantages of the above-mentioned patents are: first, in the above-mentioned patent, the infusion bottle is fixed on the fixed seat by bonding the snap-in seat at the bottom of the infusion bottle. Insert the bottle mouth of the infusion bottle, and the above-mentioned infusion bottle is not clamped or fixed, but fixed by the
adhesive clamping seat, which is very unstable. When the needle is inserted, the needle is sent upward, and the infusion bottle may be forced to rise, which is It will cause the infusion bottle to be skewed or even toppled over, which is very dangerous, and if the needle is skewed, it will be difficult to align or insert into the mouth of the bottle, which requires
medical staff to confirm, which is very inconvenient; The patent can only hold the infusion bottle, and the infusion bag cannot stand upright on it, so the use is limited; third, as we all know, the drip rate of the liquid needs to be strictly controlled during the infusion process. During the infusion process, the drip rate often changes, and the
medical staff cannot always Fourth, during the infusion process, we know that the drip rate is too fast or too slow, which is not good for the health of the patient. As far as possible, if the infusion bottle is not replaced in time, or the
medical staff does not find it in time, sucking back will occur, which will endanger the health of the patient. After the
chain drive wheel arrives, the needle tube can be used for puncture. During the waiting process, you can There may be
pollution, so that when the needle tube is inserted, it may cause
contamination of the infusion, causing unnecessary infection of the patient; Sixth, the
chain drive in the above-mentioned patent is easy to wear and deform after long-term use, and the infusion bottle may not be accurately delivered to the designated position. In this way, the action of automatically changing the infusion bottle cannot be realized, and the operation is inconvenient
