Description
Technical Field
The invention belongs to the technical field of medical use, and particularly relates to a universal type pressure-reducing and centralized-control automatic bottle changing device for medical transfusion.
Background
The inventor has a series of invention patents in the research aspect of the automatic bottle changing device for medical transfusion. The technical route is from electronic control to physical principle control (mainly floating ball valve control); from a simple hard bottle or a simple soft bottle to a universal type automatic bottle-changing infusion head. The functions of the infusion head are more and more powerful, the use is more and more convenient, but the universal automatic bottle-changing infusion head has some defects in the use process, and the specific expression is as follows: (1) When the second or third infusion head is not inserted into the infusion bottle for infusion, a bracket is needed to fix the second or third infusion head and keep the second or third infusion head vertical as much as possible, which increases the difficulty in use. (2) When a large bottle (such as 500 ml) and a small bottle (such as 50 ml) are used at the same time, the infusion head is difficult to keep on the same horizontal plane and is smoothly connected, and part of the infusion head can be too inclined to cause the failure of the floating ball valve, so that safety accidents are caused, because the floating ball valve can be normally used only within a certain inclination angle range, that is, the infusion head is kept vertical as much as possible during use. (3) When in use, the infusion head is inconvenient to move, not only the infusion head which is temporarily not used after being fixed by the bracket is needed to be reused, but also the infusion head is possibly turned over to be fixed again (because the bracket is sometimes taken off from the ceiling and then turned over), and the infusion head is kept vertical as much as possible, so that the existing bracket cannot be directly utilized to conveniently move and shift. In addition, the infusion bottles can be mutually extruded to cause overlarge inclination angle of the infusion head during moving and displacement, so that potential safety hazards are caused.

Example 1
Referring to fig. 1 to 7, a universal type pressure-reducing and centralized-control automatic bottle changing device for medical infusion is connected with three infusion bottles 1, and comprises three infusion systems which are sequentially connected, wherein one infusion system corresponds to one infusion bottle 1.
Each infusion system comprises an infusion bottle tube unit, a decompression and exhaust unit 3 and an automatic bottle changing unit 5 which are sequentially communicated from top to bottom.
Wherein the infusion bottle tube unit comprises two infusion bottle tubes 11.
The decompression and exhaust unit 3 comprises two decompression chambers 31, and one decompression chamber 31 corresponds to one infusion bottle tube 11.
Specifically, the bottom of each decompression chamber 31 is connected to the infusion bottle 1 through the infusion bottle tube 11 with its one side opening upward, and the other side opening is provided with a decompression tube 33. One end of the decompression pipe 33 is opened in the decompression chamber 31, and the other end is communicated with the automatic bottle changing unit 5. Two exhaust valves 35 are arranged at the bottommost end of the infusion bottle tube 11, namely at the joint of the infusion bottle tube 11 and the decompression chamber 31, and one exhaust valve 35 corresponds to one decompression chamber 31.
The automatic bottle changing unit 5 comprises two floating balls 51 and two communicated floating ball valve chambers 53.
Specifically, the floating ball 51 is disposed in the floating ball valve chamber 53 to form two floating ball upper valves 55 and two floating ball lower valves 57, and one floating ball 51 corresponds to one floating ball valve chamber 53, one floating ball upper valve 55 and one floating ball lower valve 57. The bottoms of the two float valve chambers 53 are communicated and are controlled to open and close by a float lower valve 57. The floating ball upper valve 55 is connected to the pressure reducing pipe 33, and one floating ball upper valve 55 corresponds to one pressure reducing pipe 33. The side of the first float valve chamber 53 of the first infusion system is provided with an air intake and liquid blocking valve 7.
Specifically, the second float valve chamber 53 of the first fluid delivery system is in communication with the first float valve chamber 53 of the second fluid delivery system. The second ball valve chamber 53 of the second infusion system communicates with the first ball valve chamber 53 of the third infusion system.
Wherein, six decompression chambers 31 are arranged in a triangle shape, and six floating balls 51 are also arranged in a triangle shape.
Specifically, each infusion bottle tube 11 has a certain length and is also bendable.
Wherein the decompression chamber 31 has an inverted semicircle-tapered shape.
Specifically, the opening at one side of the conical tip of each decompression chamber 31 is upwards connected with the infusion bottle 1 through the infusion bottle tube 11, and the opening at the other side is provided with a decompression pipeline 33.
In particular, each of the three infusion systems is marked with the same identification, which can be distinguished by color.
The working principle and the working process of the invention are as follows:
the bottle changing control mechanism (mainly the floating ball upper valve 55 and the floating ball lower valve 57) can be kept vertical at any time (gravity suspension principle) by postponing the bottle changing control (namely, the bottle changing is not controlled at the infusion head but is controlled at a distance behind the infusion head) and the bottle changing control mechanism is controlled in a centralized manner, so that the control valve to be used is always kept in a relatively vertical state, and a bracket fixing device is avoided. However, the hydraulic pressure of the pipeline increases after the delay control, and it is difficult to close the pipeline by only buoyancy of the upper float valve 55 and the lower float valve 57, so that a pressure reducing device must be added to reduce the increased hydraulic pressure after the delay centralized control bottle changing. In addition, after the control is delayed, the pipeline is prolonged, so that the pipeline needs to be exhausted before liquid is infused, and safety accidents caused by excessive gas entering the Murphy's dropper are avoided.
When the second infusion bottle 1 is a hard bottle. After the previous bottle is infused, air enters the first floating ball valve chamber 53 of the second infusion system from the second floating ball valve chamber 53 of the first infusion system, the floating ball 51 is changed from the original floating state to the sinking state, as shown in fig. 6, the floating ball upper valve 55 is opened, the floating ball lower valve 57 is closed, air only enters the second bottle hard bottle through the floating ball upper valve 55, at this time, liquid in the second bottle hard bottle enters the second floating ball valve chamber 53 of the second infusion system after being depressurized through the infusion bottle pipe 11, and then flows out of the centralized bottle changing controller to enter the Murphy's dropper after passing through the third infusion system (the third infusion system state is that the two floating ball upper valves 55 are closed, and the two floating ball lower valves 57 are opened as shown in fig. 7), and then is infused into a human body.
When the second infusion bottle 1 is a soft bottle. The second infusion system is in the original state: as shown in fig. 7, the two upper float valves are closed and the two lower float valves are opened, because the first bottle of liquid flows into the two float valve chambers 53 of the second infusion system to float the float 51. After the first bottle of liquid is infused, air enters the first float valve chamber 53 of the second infusion system, the float ball 51 in the first float valve chamber 53 sinks, the first float ball upper valve 55 is opened, the first float ball lower valve 57 is closed, the second float ball upper valve 55 of the second infusion system is always closed because the soft bottle does not need to be charged, the second float ball lower valve 57 is always opened, the liquid in the second bottle flows into the first float valve chamber 53 of the second infusion system after being depressurized, the float ball 51 in the first float valve chamber 53 rises, the first float ball upper valve 55 is closed again, the liquid in the first float ball valve chamber 53 flows backwards, the first float ball 51 descends again, the first float ball upper valve 55 is opened again, the liquid in the second bottle is input again, and the soft bottle of the second bottle starts to realize pulse infusion.
It should be noted that: the first, second, and third infusion systems of this embodiment refer to the first, second, and third infusion systems in the left-to-right direction in fig. 1.
The invention has the advantages and beneficial effects that:
1. the invention is easy to use; because of centralized control and attachment to the infusion bottle tube 11 of the first infusion system, a temporary stand-by control device can be realized, and the approximately vertical state can be maintained all the time without the need for a specific bracket for fixation.
2. The invention has high safety; since the infusion bottle tube 11 has a certain length and can be bent, the infusion bottle tube can be connected with a large bottle or a small bottle at will in the use process, and the vertical characteristic of the control device is not affected.
3. The invention is convenient in shifting; the bottle changing device for standby is not required to be specially fixed or reversed and fixed during carrying and displacement.
4. The invention has simple structure; compared with the prior art, the automatic bottle changing unit structure is simpler and is convenient for processing and production.
The above examples illustrate only one embodiment of the invention, which is described in more detail and is not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
