Problems solved by technology
[0002] The drip bottle usually relies on the gravity of the liquid medicine as the driving force when it is used, so the drip stand is generally high, it is inconvenient to move and it may be knocked over, which has certain safety hazards, and the simple pressurization will cause the air pressure in the drip bottle to be too high , the input speed of the medicine solution is too fast. On the other hand, after a bottle of drip is exhausted, the nursing staff needs to manually replace the medicine bottle, which increases the workload of the nursing staff. At the same time, if the drip bottle is not replaced in time, there is a possibility of blood backflow

Embodiment Construction
[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, can be combined in any way, except for mutually exclusive features and or steps.
[0020] Combine below Figure 1-6 The present invention is described in detail, and for convenience of description, the orientations mentioned below are now stipulated as follows: figure 1 The up, down, left, right, front and back directions of the projection relationship itself are the same.
[0021] like Figure 1-6 As shown, a drip stand with automatic pressure regulation and medicine bottle replacement function of the device of the present invention includes a main body box 10, and three left and right medicine bottle chambers 21 arranged equidistantly and opening upwards are arranged in the main body box 10. The lower side of the medicine bottle cavity 21 is connected with a bottle cap cavity 18, and the lower side of the bottle cap cavity 18 is connected with a transverse limiting cavity 8...

The invention discloses a drip stand with automatic pressure regulating and medicine bottle replacing functions. The drip stand comprises a main body box, three medicine bottle cavities with upward openings are formed in the main body box at equal intervals in the left-right direction, the lower side of each medicine bottle cavity communicates with a bottle cap cavity, the lower side of the bottlecap cavity communicates with a transverse limiting cavity with a forward opening, the lower sides of three transverse limiting cavities communicate with a sliding box cavity with a forward opening, and the rear side of the sliding box cavity communicates with an insertion gear cavity. The pressurization is completed by piston reciprocation, therefore, a drip bottle does not need to be always keptat a certain height and is convenient to move, and the pressure difference between a liquid medicine cavity and the outside is sensed through a sensing plate, so that the pressurization degree is controlled, and the too high liquid medicine flow speed caused by excessive pressurization is avoided. The weight of the medicine bottle is sensed through the annular pressing plate, bottle replacement operation is automatically completed after liquid medicine drips off, and blood backflow caused by untimely medicine bottle replacement is avoided while the workload of nursing personnel is reduced.
Description
technical field [0001] The invention relates to the related technical field of medical nursing devices, in particular to a drip stand with functions of automatic pressure regulation and medicine bottle replacement. Background technique [0002] The drip bottle usually relies on the gravity of the liquid medicine as the driving force when it is used, so the drip stand is generally high, it is inconvenient to move and it may be knocked over, which has certain safety hazards, and the simple pressurization will cause the air pressure in the drip bottle to be too high , the input speed of the medicine solution is too fast. On the other hand, after a bottle of drip is exhausted, the nursing staff needs to manually replace the medicine bottle, which increases the workload of the nursing staff. At the same time, if the drip bottle is not replaced in time, there is a possibility of blood backflow . Contents of the invention [0003] Aiming at the deficiencies of the above-mentione...
