According to the above structural features of the present application, the embodiments of the present application will be further explained:
referring to fig. 1 to 8, the embodiment provides an automatic medicine changing bottle for pediatric infusion, which includes a medicine bottle unit 1, wherein a hanging ring 15 is installed at the center of the upper end of a bottle body 11 of the medicine bottle unit 1 through annular clamping; the lower end of the bottle body 11 is connected with a bottle head 13; the side wall of the upper end of the bottle head 13 is provided with an air inlet pipe 12 through screw threads; the central position of the lower end of the bottle head 13 is provided with a hook 14 in an annular clamping way; the lower extreme of bottle head 13 is opened there is first bottleneck 17, install first sealed rubber cap 171 through annular joint in the first bottleneck 17.
A support ring 16 is fastened on the inner wall of the bottle head 13 through cold contraction, and the support ring 16 is in an oblate column shape; the right side of the branch ring 16 is provided with a vent hole 161, and the vent hole 161 is communicated with the second bottle opening 18; a second sealing rubber cap 181 is clamped and mounted in the second bottle mouth 18 in an annular manner; the rotary valve 2 is arranged in the center of the branch ring 16; the rotary valve 2 is columnar, the rotary valve 2 is axially connected with the support ring 16 through the rotating shaft 162, and the radial side surface of the rotary valve 2 is in clearance fit with the inner wall of the support ring 16.
A three-way through hole 21 is formed in the axial center section of the rotary valve 2, and the included angles of the first through hole 211, the second through hole 212 and the third through hole 213 are all 120 degrees; the first through hole 211 is vertical; two sides of the first through hole 211 are respectively provided with a cavity 22; the shape and the size of the cavity 22 are completely equal, and the cavity is not communicated with the first through hole 211; two sides of the second through hole 212 are respectively fixed with a balancing weight 23, the shape and the size of the balancing weight 23 are completely equal, and the groove for installing the balancing weight 23 is not communicated with the second through hole 212.
The infusion set comprises an infusion set 3, wherein a first bottle plug puncture needle 32 is fixed at the top end of the infusion set 3, and a needle head 31 is fixed at the bottom end of the infusion set.
The novel bottle stopper puncture needle comprises a flexible pipe 4, wherein a third bottle stopper puncture needle 42 is fixed at the top end of the flexible pipe, and a second bottle stopper puncture needle 41 is fixed at the bottom end of the flexible pipe.
The bottle body 11, the bottle head 13, the first bottle mouth 17 and the second bottle mouth 18 are connected through integral blow molding, and are made of transparent plastics, such as medical transparent PVC. So as to observe the condition of the liquid level in the vial unit 1.
The rotary valve 2 is made of light plastic such as medical PVC, so that the obstruction of the self weight of the rotary valve 2 to the rotation of the rotary valve is reduced as much as possible.
The counterweight 23 is made of non-toxic metal, such as titanium alloy. Based on the gravity action of the balancing weight 23, metal with higher density is required to be selected; since the liquid medicine is directly injected into the body, nontoxic materials must be selected.
The working principle is as follows:
firstly, respectively preparing liquid medicine in the medicine bottle units 1, serially hanging a plurality of medicine bottle units 1 and hanging rings 15 through hooks 14, and hanging the hanging ring 15 at the topmost end on an infusion support; then, inserting a second bottle stopper puncture needle 41 into the second sealing rubber cap 181 of the bottommost medicine bottle unit 1, and inserting a third bottle stopper puncture needle 42 at the other end of the hose 4 into the first sealing rubber cap 171 of the upper medicine bottle unit 1; the rest is done in sequence until all the medicine bottle units 1 are communicated;
secondly, inserting the first bottle stopper puncture needle 32 of the infusion apparatus 3 into the first sealing rubber cap 171 of the bottommost medicine bottle unit 1, and pricking the needle head 31 into the body of the patient to start infusion;
when the rotary valve 2 is immersed in the liquid medicine, the solid plastic has no influence on the rotation due to the average density; the gas in the cavity 22 is subjected to the buoyancy of the liquid medicine, so that the first through hole 211 tends to keep upright; the counterweight 23 receives the self gravity and the buoyancy of the liquid medicine at the same time; the rotary valve 2 thus assumes a substantially upright and slightly inclined to the left. Therefore, the first through hole 211 of the rotary valve 2 keeps a basically vertical state, and the liquid medicine passes through the rotary valve 2 from top to bottom through the three-way through hole 21 and enters the human body through the first bottle mouth 17 and the infusion apparatus 3; after the liquid medicine in the upper medicine bottle unit 1 flows through the hose 4, the liquid medicine is blocked by the side wall of the rotary valve 2 at the vent hole 161 in the lower medicine bottle unit 1 and does not flow downwards;
thirdly, when the liquid level of the liquid medicine in the lower medicine bottle unit 1 is lowered to be below the support ring 16, the cavity 22 is not influenced by the buoyancy of the liquid medicine any more, the rotary valve 2 is forced to rotate anticlockwise by the gravity of the balancing weight 23, and the clamping angle 24 contacts the support ring to stop the rotary valve 2 from rotating continuously when the hole 213 of the third through hole is communicated with the vent hole 161;
at this time, a passage is formed, the liquid medicine in the upper medicine bottle unit 1 flows into the third through hole through the vent hole 161 in the lower medicine bottle unit 1, and then the liquid medicine has two directions, wherein the first liquid medicine flows through the second through hole 212, the first bottle mouth 17 and the infusion apparatus 3 and enters the human body; the two flows enter the bottle body 11 through the first through hole 211, but the gas cannot be discharged because the conventional gas inlet tube 12 is a one-way tube, so the gas pressure in the bottle body 11 is increased, and the liquid medicine is pressed to rotate the valve 2 and flows into the second through hole 212.
In conclusion, the technical requirement that the liquid medicine is injected into the patient body from the lower medicine bottle unit 1 to the upper medicine bottle unit 1 in sequence is met, the automation of the medicine changing technology is realized, and the operation burden of nursing staff is greatly reduced.
To the technical personnel in the field, according to the guidance of the utility model, under the premise of not deviating from the principle and spirit of the utility model, it is right that the change, modification, replacement, deformation that the utility model was done still fall into the protection scope of the utility model.
