Description
Technical Field
The invention relates to an infusion drop number precise regulator.
Background
In clinical infusion therapy, there is a strict limit to the number of infusion drops for infants and patients with cardiopulmonary insufficiency, or patients undergoing infusion therapy with special drugs such as chemotherapeutic drugs and mannitol. Too low infusion speed can cause the concentration of blood drugs to be reduced, and the treatment effect is influenced; too fast infusion speed can cause complications such as acute pulmonary edema, heart failure and the like, and seriously affect the life safety of patients. How to accurately regulate the number of drops is a problem which needs to be solved urgently in clinical practice at present. At present, a common method for clinically adjusting the number of drops of liquid is a visual liquid drop number counting method, namely the number of drops of liquid medicine at the upper end of a Murphy's dropper dropped for 1 minute, the method has large error, cannot accurately adjust the number of drops of liquid, wastes time and labor, and cannot completely meet the requirement for clinically and accurately adjusting the number of drops. The infusion pumps which are commonly used in clinic at present control the liquid speed according to XX ml/h, but no specific drop number adjusting instrument exists at present, although the accuracy of the infusion amount of the infusion pump is ensured, the infusion pump has large volume, high manufacturing cost and inconvenient use, and cannot be put into use in large quantity, and if the infusion pumps are adopted in daily infusion, the infusion cost can be greatly increased, so that the economic burden of patients is increased.
Disclosure of Invention
The invention aims to provide an infusion drop number precise regulator which can precisely regulate and display the infusion drop number of an infusion tube in real time, and is convenient for medical care and patients to precisely regulate according to requirements.
In order to solve the technical problem, the invention provides an infusion drop number precise regulator, which comprises a regulator body, a vibration sensor, a digital display board integrated with a controller and a power supply and a fixing clamp, wherein the controller is connected with the vibration sensor;
the regulator body comprises a horizontally-arranged base, the base is in a U shape with a forward-arranged notch, the bottom of the notch of the base is in a circular arc shape, a channel which is horizontally arranged and communicates the bottom of the notch with the circumferential outer side of the base is arranged on the base, a spiral push rod is arranged at the position, corresponding to the channel, of the circumferential outer side of the base, and a movable end of the spiral push rod penetrates into the notch of the base from the channel;
the vibration sensor is in a horizontally arranged circular arc shape, the shape of the vibration sensor is matched with the shape of the notch of the base, and the vibration sensor is arranged at the position above the base, corresponding to the notch;
the digital display board is vertically arranged at the edge of the upper side of the base, and a controller of the digital display board is electrically connected with the vibration sensor;
the fixation clamp includes two vertical rectangular shape splint of arranging and the horizontal trend, the one end of two splint links to each other through an articulated seat, the articulated shaft of articulated seat is vertical trend, articulated seat downside links to each other with the digital display board upside, one of them splint length direction keeps away from the one end of articulated seat and is equipped with the jack that runs through splint, another splint length direction keeps away from the one end of articulated seat and is equipped with the contact pin with jack assorted, the tip that splint were kept away from to the contact pin is equipped with the bulb, the bulb diameter slightly is greater than the jack diameter, two splint length direction's middle part region is equipped with the portion of stepping down that is used for the centre gripping transfer line of mutual disposition.
For the sake of simplicity, the precise regulator for infusion drop number is simply referred to as the present regulator.
The use method and the advantages of the regulator are as follows: when in transfusion, the regulator is clamped at the Murphy's dropper of the transfusion tube, so that the vibration sensor is tightly attached to the lower side surface of the Murphy's dropper, then the two clamping plates are closed, the inserting needle is inserted into the inserting hole, the diameter of the ball head is slightly larger than that of the inserting hole, the inserting hole is slightly deformed when the inserting needle is inserted into the inserting hole, the ball head can play a role of locking after being inserted, then the nut of the spiral push rod is rotated to tightly abut the movable end of the spiral push rod against the wall of the transfusion tube, at the moment, because the liquid drop in the Murphy's dropper falls down and has a downward impulse to the Murphy's dropper, when any liquid drop falls down, the Murphy's dropper can generate slight vibration, the vibration sensor detects the vibration and then transmits a vibration signal to the controller, the controller calculates the transfusion speed by detecting the interval time of the vibration and displays the transfusion speed on the digital display board, at the moment, the extrusion degree of the spiral push rod is adjusted according to the transfusion speed displayed by the digital display board, thereby achieving the effect of regulating the transfusion speed.
It should be noted that, during infusion, the manmade pulling of the infusion tube may also cause the murphy's dropper to vibrate, if all the vibrations are counted in, there may be a great misjudgment, but the vibration amplitude generated by the falling of the liquid drop is completely different from the vibration amplitude and frequency caused by pulling of the infusion tube, and a suitable algorithm may be programmed in the controller to eliminate the vibration caused by pulling of the infusion tube, and the infusion speed is calculated only according to the vibration generated by the falling of the liquid drop, and the editing of the corresponding algorithm according to the actual need is an existing mature technology, and the detailed description is not given in this application, and those skilled in the art can edit the algorithm according to the actual need.
