Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a portable infusion control device for clinical nursing of general surgery. Background Art

[0002] A disposable infusion set is a common medical consumable. After sterilization, a channel between the vein and the liquid medicine is established for intravenous infusion. It is generally composed of a syringe needle, an infusion hose, a liquid medicine filter, a flow rate regulator, a Moffitt dropper, a bottle stopper puncture, an air filter, a dosing port and other structures. However, the flow rate regulator on the infusion set is not accurate enough to use, and needs to rely on the experience of medical staff to control it. It is impossible to strictly control the speed of infusion. At present, in medical equipment, an infusion pump is usually used to control the infusion flow rate. However, the body of the infusion pump is relatively bulky and needs to be pushed with a medical cart. It is cumbersome to use and not portable. For this reason, portable infusion controllers have gradually been developed to facilitate the infusion work of medical staff.

[0003] At present, a patent with application number 201910482849X discloses an infusion controller, including: an infusion device support formed with an accommodating cavity; a sliding block unit arranged in the accommodating cavity for clamping the drip pot of the infusion device in the accommodating cavity, the drip pot is located above the sliding block unit; a drip rate adjustment unit arranged on the infusion device support and acting on the lower infusion hose of the drip pot; wherein the infusion device support is also provided with a monitoring unit for monitoring the number of infused drops in the drip pot. The infusion controller can accurately record the number of infused drops and the drip rate. Similarly, a patent with application number 201811465707.4 discloses an infusion drip rate monitor, including a clamp ring, a fixing plate installed at one end of the clamp ring, and a strap installed at the other end of the clamp ring. The fixing plate is also provided with a clamping device. The infusion drip rate monitor bends the clamp ring through the strap and clamps it on the Moffitt dropper. The first locking bolt is screwed into the limit groove to lock and fix the strap so that the strap is in a taut state as a whole, and the clamp ring can be clamped on the Moffitt dropper, which is convenient for detecting the dripping of the Moffitt dropper.

[0004] The above two technical solutions both use sensors to detect the number of drops of the medicine in the Moffitt dropper and calculate the flow rate of the medicine. The patent technology with application number 201910482849X also records a drip rate adjustment unit that can control the drip rate. However, there are still some disadvantages in actual use: 1) When infusing different solutions, the infusion method is different. For example, for conventional infusion, it is necessary to be slow first and then fast, that is, first use a slow infusion to allow the patient to build tolerance, and then speed up the infusion speed after the patient gradually adapts. For burns, shock, and surgical blood transfusion, it is necessary to be fast first and then slow, that is, first quickly replenish the fluid, and when the patient is in a state of shock, the infusion speed is increased. When the infusion rate tends to be stable, the fluid replenishment rate is reduced. The above technical solution cannot automatically adjust the infusion rate, and medical staff are required to go to the ward manually to adjust it at a fixed time, which increases the labor intensity of medical staff; 2) During the infusion process, the liquid level in the Mouphy's dropper will change under certain circumstances. When the infusion is not smooth and the infusion hose is bent, the liquid level in the Mouphy's dropper will rise. When the air tightness of the dosing port or other components fails, the liquid level in the Mouphy's dropper will drop. The above two technical solutions cannot detect and warn. Therefore, it is urgent to propose a portable infusion control device for general surgery clinical nursing. Summary of the invention

[0027] A preferred embodiment is provided below:

[0028] A portable infusion control device for general surgery clinical nursing, such as Figure 1-3 As shown, it includes: a housing 100 formed with a receiving cavity 110, the receiving cavity 110 is used to place the Moffey dropper 810 of the infusion device 800; a fixing unit 200 arranged on the housing 100 for fixing the Moffey dropper 810; a monitoring unit 300 arranged on the housing 100 for monitoring the number of drops of the Moffey dropper 810; a drip rate adjustment unit 400 arranged on the housing 100 and acting on the upper infusion hose 820 of the Moffey dropper 810; a timer 500 for timing arranged on the housing 100; a display and control unit 600 for digital display and control arranged on the housing 100; and a controller 700 and a power supply assembly (not shown in the figure) for controlling the operation of the infusion control device. ), the controller 700 receives the signal of the number of drops per unit time from the monitoring unit 300, calculates the dripping speed, and displays it on the display and control unit 600; the display and control unit 600 is electrically connected to the controller 700, and the display and control unit 600 includes a first state setting module 610 and a second state setting module 620, the first state setting module 610 is used to set the initial dripping speed, the second state setting module 620 is used to set the second dripping speed, and the working time of the initial dripping speed is set by the timer 500. After the timer 500 completes the timing, the controller 700 controls the dripping speed adjustment unit 400 to work, so that the dripping speed of the Moffitt dropper 810 is at the second dripping speed.

[0029] When in use, the Moffitt dropper 810 of the infusion device 800 is placed in the accommodating chamber 110, and the position of the Moffitt dropper 810 is fixed by the fixing unit 200. The initial dripping rate and the second dripping rate of the Moffitt dropper 810 are respectively set by the first state setting module 610 and the second state setting module 620 in the display and control unit 600. During infusion, the dripping rate adjustment unit 400 controls the infusion hose 820 to gradually open from the closed state, and the liquid medicine gradually drips from the top of the Moffitt dropper 810, and the monitoring unit 300 controls the initial dripping rate and the second dripping rate of the Moffitt dropper 810 to gradually open from the closed state. The drip count signal is monitored and sent to the controller 700, the controller 700 calculates the actual drip rate and compares it with the set initial drip rate until the actual drip rate corresponds to the initial drip rate, the timer 500 starts timing, and the working duration of the initial drip rate is set by the timer 500. When the timer 500 completes the timing, the signal is sent to the controller 700, the controller 700 sends a signal to the drip rate adjustment unit 400, and the drip rate adjustment unit 400 works to adjust the actual drip rate to the second drip rate, thereby realizing the function of automatically adjusting the drip rate.

[0030] In a specific application scenario, the medical staff installs the Moffitt dropper 810 of the infusion set 800 into the accommodating cavity 110 and fixes the position through the fixing unit 200, connects the infusion set 800 to the medicine bottle, manually presses the Moffitt dropper 810 to make the medicine liquid in the Moffitt dropper 810 reach an appropriate height, and the medicine liquid level cannot be higher than the monitoring position of the monitoring unit 300, starts the infusion control device, and the drip rate adjustment unit 400 closes the infusion hose 820. The medical staff inserts the injection needle into the patient's vein, and sets the initial drip rate and the second drip rate of the Moffitt dropper 810 through the first state setting module 610 and the second state setting module 620 respectively. When performing conventional infusion, the first state setting module 610 sets the The set initial dripping rate is slower than the second dripping rate. The working time of the initial dripping rate is set by the timer 500, which is generally in the range of twenty minutes to one hour. The time set by the timer 500 is to build tolerance for the patient and adapt to the infusion speed. After the timer 500 completes the timing, it sends a signal to the controller 700, and the controller 700 sends a signal to the dripping rate adjustment unit 400. The dripping rate adjustment unit 400 adjusts the actual dripping rate to the second dripping rate. At this time, the patient has completed the adaptation and increases the speed to the second dripping rate to reduce the infusion time. This process does not require medical staff to make adjustments, thereby reducing the workload of medical staff. Similarly, for patients with burns, shock, and surgical blood transfusions, the initial dripping rate is greater than the second dripping rate.

[0031] As an embodiment of the present invention, the accommodating cavity 110 includes: a drip pot cavity 811 for placing a Moffey dropper 810; an upper hose cavity 812 for placing an infusion hose 820 above the Moffey dropper 810; a lower hose cavity 813 for placing an infusion hose 820 below the Moffey dropper 810; and a dosing tube cavity 814 for placing a dosing tube.

[0032] As an embodiment of the present invention, the fixing unit 200 includes a baffle, which is rotatably mounted on the shell 100. The baffle is used to limit the infusion hose 820 and the dosing tube above the Moffitt dropper 810 to the upper hose cavity 812 and the dosing tube cavity 814 respectively. When in use, the infusion hose 820 and the dosing tube are fixed by rotating the baffle, thereby limiting the Moffitt dropper 810 in the drip pot cavity 811, and the display and control unit 600 is mounted on the baffle.

[0033] As an embodiment of the present invention, the monitoring unit 300 is a slot-type photoelectric sensor, and the light emitting head and the receiving head of the slot-type photoelectric sensor are respectively arranged on both sides of the drip pot cavity 811. When the medicine drop passes through the slot-type photoelectric sensor, the light emitted by the light emitting head is scattered, and the amount of light received by the receiving head is reduced, thereby generating a pulse electrical signal. The controller 700 receives the pulse electrical signal and records it as one drop. The controller can calculate the dripping rate based on the number of pulse electrical signals received in unit time, and display it in the display and control unit 600.

[0034] As an embodiment of the present invention, the drip rate adjustment unit 400 includes an upper top block 410 and a first drive assembly 420. The upper top block 410 slides through the side wall of the upper hose cavity 812. The first drive assembly 420 is used to drive the upper top block 410 in and out of the upper hose cavity 812, so that the upper top block 410 squeezes the infusion hose 820 above the Moffitt dropper 810 to achieve control of the drip rate.

[0035] Furthermore, the first drive component 420 includes a servo motor 421, a screw 422, a slider 423, a connecting rod 424, and a limiting groove 425. The servo motor 421 is fixedly installed in the shell 100. The output end of the servo motor 421 is connected to the screw 422. The screw 422 threadedly penetrates the slider 423. One end of the connecting rod 424 is hinged on the slider 423. The other end of the connecting rod 424 is hinged to the upper top block 410. The upper top block 410 is slidably connected in the limiting groove 425. The limiting groove 425 is used to limit the upper top block 410 so that the upper top block 410 can perform translational movement. The structure is reasonable to meet the requirements of portability.

[0036] As an embodiment of the present invention, the timer 500 adopts a knob-type mechanical timer. Compared with an electronic timer, the knob-type mechanical timer uses a spring as power, does not require electricity consumption, and increases the standby time of the infusion control device. At the same time, there is no need to operate on the display and control unit 600. Just turn the knob to the required time, which is more convenient to use.

[0037] As an embodiment of the present invention, an alarm 310 is provided on the shell 100, and the alarm 310 is electrically connected to the controller 700. When the monitoring unit 300 cannot detect dripping, it means that the liquid in the medicine bottle has been infused, or the infusion tube is bent and blocked, causing the liquid level in the Moffitt dropper 810 to exceed the detection height of the slot-type photoelectric sensor. At this time, the controller 700 controls the alarm 310 to sound an alarm, prompting medical staff to come for treatment.

[0038] As an embodiment of the present invention, the monitoring unit 300 is two or more groups of slot-type photoelectric sensors. A slot-type photoelectric sensor through which liquid droplets pass indicates that the liquid level is lower than the position of the slot-type photoelectric sensor. When the slot-type photoelectric sensor located below cannot detect liquid droplets, it indicates that the liquid level is between the two slot-type photoelectric sensors, thereby enabling the liquid level of the Moffitt dropper 810 to be monitored.

[0039] As an embodiment of the present invention, a liquid level control unit 900 for controlling the liquid level in the Moffitt dropper 810 is provided on the shell 100, and the liquid level control unit 900 includes: a lower top block 910 for squeezing the infusion hose 820 below the Moffitt dropper 810; a second driving assembly 920 for driving the lower top block 910 to move; a side top plate 930 for squeezing the side wall of the Moffitt dropper 810; and a third driving assembly 940 for driving the side top plate 930, the lower top block 910 slides through the side wall of the lower hose cavity 813, the second driving assembly 920 is connected to the lower top block 910, and the third driving assembly 940 is connected to the side top plate 930.

[0040] Furthermore, the second driving assembly 920 and the third driving assembly 940 both adopt electric push rods, and the side top plate 930 is an L-shaped structure. The side top plate 930 is rotatably mounted on the shell 100. A notch for the side top plate 930 to pass through is provided on the side wall of the drip pot cavity 811. The third driving assembly 940 is used to push the side top plate 930 to rotate, so that the side top plate 930 squeezes the Moffitt dropper 810 in the drip pot cavity 811.

[0041] When the liquid level of the Moffitt dropper 810 drops above a preset threshold, the controller 700 controls the second drive assembly 920 to operate, pushing the lower top block 910 to squeeze the infusion hose 820, so that the infusion hose 820 below the Moffitt dropper 810 is closed, and then controls the third drive assembly 940 to operate, pushing the side top plate 930 to rotate, so that the side top plate 930 squeezes the Moffitt dropper 810 in the drip pot cavity 811. After the third drive assembly 940 is reset, the Moffitt dropper 810 is restored, and the negative pressure is used to suck the liquid in the medicine bottle into the Moffitt dropper 810, thereby raising the liquid level, and medical staff are no longer needed to come and deal with it.

[0042] As an embodiment of the present invention, a clamping claw is provided on the outer side of the shell, and the clamping claw is used to clamp on the infusion stand.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
