DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The embodiment of the present application provides a portable infusion drop rate display, which solves the problem that the existing infusion alarm has a single function and cannot accurately count the number of drops, and realizes the standardization, normalization and automation of infusion monitoring.

[0034] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Embodiment 1:

[0036] A portable infusion drip rate display instrument, such as Figure 1 As shown, it includes: a housing 1, a droplet monitoring component 2, a droplet rate adjustment component 3, a display 4, an adjustment button 5, a control circuit board 6, and an early warning component 7.

[0037] The housing 1 is used to accommodate a droplet monitoring component 2, a drop rate adjustment component 3, a display 4, an adjustment button 5, a control circuit board 6, and an early warning component 7 control circuit board 6. In order to facilitate carrying and use, the volume of the entire housing 1 is small, and the length, width and height of the housing 1 are 30*40*50mm. The housing 1 is a box body with a hollow interior, and the middle part of an outer surface of the box body is recessed into the interior of the box body to form a dropper receiving groove 8. The dropper receiving groove 8 is adapted to the dropper pot of the dropper and the dropper part at the upper end of the dropper pot, so that when monitoring the number of droplets of the dropper, the dropper pot part and the dropper part at the upper end of the dropper pot can be just stuck in the dropper receiving groove 8 without affecting the normal flow of droplets in the dropper.

[0038] In addition, in order to arrange other components in the housing 1 in a more scientific and reasonable manner, in this embodiment, a more preferred way is to subdivide the hollow box body into four separate small boxes, namely, the first, second, third and fourth boxes, from top to bottom and from left to right, based on the position of the dropper receiving groove 8. The subdivided small boxes are used to arrange the droplet monitoring component 2, the dripping speed adjustment component 3, the display 4, the adjustment button 5, the control circuit board 6, and the warning component 7, respectively. Figure 1-4 As shown, specifically:

[0039] The droplet monitoring component 2 is installed in the second box body and / or the fourth box body, and is closely attached to the inner wall of the second box body and / or the fourth box body on the side close to the dropper receiving groove 8. The droplet monitoring component 2 is used to monitor the droplets falling from the drip pot, so its height in the second box body and / or the fourth box body is set in principle to facilitate monitoring of the droplets in the drip pot, and is not specifically limited. The optimal position is biased towards the middle and upper end of the second box body and / or the fourth box body, for example, 5-8 mm from the top.

[0040] The quantity of the droplet monitoring component 2 is not specifically limited, and can be one, two or more. In the present embodiment, in order to more accurately monitor droplets on the basis of controlling the suitable volume of the portable infusion dripping speed display instrument, the droplet monitoring component 2 is set to two, and the two droplet monitoring components 2 are respectively installed in the middle and upper end positions in the second box body and the fourth box body.

[0041] In addition, in order to avoid interference from the PP and PE materials of the dropper wall, so that the droplets can be accurately counted through the dropper, a preferred method is that the droplet monitoring component 2 is a photoelectric sensor, which detects information such as the appearance and existence of droplets based on the photoelectric effect and optical principles. In specific implementation, the droplets in the drip pot are detected by the photoelectric sensor, and the moment when the droplets fall is regarded as a detection, and the time data is recorded. When the second droplet is detected, it is recorded again to obtain the dripping speed data, and the drop number data is displayed on the display 4.

[0042] The dripping speed regulating assembly 3 is installed in the third box body, and it regulates the dripping speed by tightening or loosening the dropper. Wherein, the dripping speed regulating assembly 3 comprises a driving component 31 and a tensioning component 32 fixed on the output shaft of the driving mechanism. A through hole is provided on the side wall of the third box body near the dropper accommodating groove 8 side, and the tensioning component 32 just contacts with the part of the dropper at the upper end of the drip pot after passing through the through hole. In specific implementation, the driving component 31 includes but is not limited to being a driving motor, and the tensioning component 32 includes but is not limited to being a cam, as long as the corresponding function can be realized. When the driving motor rotates, the speed regulating cam will be driven to rotate, and the speed regulating cam will squeeze the dropper to ensure the tightening of the dropper, thereby keeping the dripping speed constant.

[0043] In addition, when specifically implementing, the dripping speed regulating assembly 3 can be set to multiple groups of driving components 31 and tensioning components 32, and other driving components 31 and tensioning components 32 can be arranged around the dropper at the upper end of the drip pot, as long as the tensioning components 32 just contact with the dropper at the upper end of the drip pot. Multiple groups of driving components 31 and tensioning components 32 work synchronously simultaneously, squeeze or relax the dropper, and keep the dripping speed of the drop in the dropper constant. In the present embodiment, considering that the portable infusion dripping speed display is small and compact, it is convenient to carry, the dripping speed regulating assembly 3 is set to a group of driving motors and cams.

[0044] The display 4, the adjustment button 5, the control circuit board 6, and the warning component 7 are all installed in the fourth box body, but the specific distribution positions of the above components in the fourth box body are not specifically limited. In this embodiment, the display 4 is arranged at the top of the fourth box body, the warning component 7 is arranged in the middle, and the adjustment button 5 is located at the bottom of the fourth box body.

[0045] The early warning component 7 is used to remind the medical staff by means of a sound alarm when no droplets are detected at the end of the infusion. Specifically, the early warning component 7 includes a buzzer 71 and an indicator light 72. When the infusion is finished and the photoelectric sensor cannot detect the droplets in the dropper, the buzzer 71 will emit a "drop" sound alarm. The indicator light 72 displays different colors, corresponding to the power-on or power-off state of the entire portable infusion drop rate display instrument.

[0046] There are two adjustment buttons 5, which are respectively used to set the dripping speed and control the switch of the buzzer 71. The principle that the adjustment button 5 sets the dripping speed is similar to the principle of setting the time of an electronic watch, and the dripping speed is set by pressing the adjustment button 5. The corresponding number of the dripping speed set can be displayed synchronously with the pressing of the button on the display 4. For example, the dripping speed is changed from 30 drops per minute to 40 drops per minute. After the setting is completed, the droplet monitoring component 2 begins to detect the dripping speed. If the dripping speed is detected to be slow, the driving motor drives the speed regulating cam to rotate, relaxes the pipe, and the dripping speed becomes faster. Another button is used to control the buzzer 71 to turn off. When the droplet buzzer 71 alarm is not detected, the buzzer 71 can be turned off by pressing the button. In addition, in the present embodiment, the display 4 is a digital display tube.

[0047] In order to make the whole internal structure of the portable infusion drip rate display instrument more compact and the overall volume smaller, the display 4, the adjustment button 5, and the warning component 7 are all integrated on the control circuit board 6, and the above-mentioned drop monitoring component 2, the drip rate adjustment component 3, the display 4, the warning component 7, and the adjustment button 5 are all electrically connected to the control circuit board 6. Among them, the control circuit board 6 includes a single chip microcomputer, specifically as Figure 4 shown.

[0048] In addition, in order to facilitate display and operation, a plurality of through holes are opened on the side wall of the fourth box body away from the dropper, and the display 4, indicator light 72 and adjustment button 5 are extended to the outside of the fourth box body through the corresponding through holes.

[0049] For ease of understanding, the principle and usage of the portable infusion drip rate display device proposed in this embodiment are explained here.

[0050] First, when the patient is receiving an infusion, hang the portable infusion drip rate display device at a suitable position near the infusion stand, and then insert the infusion dropper into it. Figure 2-3 As shown. Then turn on the portable infusion dripping speed display instrument, the indicator light 72 is on, and the instrument is in normal working state. The droplet monitoring component 2 (i.e., the photoelectric sensor) detects the droplet to complete a monitoring at the moment of dripping, and records the time data, and records again when the second drop is detected. The device can obtain the dripping speed data and display it on the display 4 (i.e., the digital display tube).

[0051] Then, as the infusion process continues, the liquid level in the infusion bottle decreases, and the dripping rate in the dropper changes accordingly. When the photoelectric sensor detects a change in the dripping rate, the sensor signal will enter the single-chip microcomputer for analysis and processing. The single-chip microcomputer then gives a signal to control the motor to rotate, driving the speed regulating cam to move. The dripping rate is kept unchanged by the degree to which the speed regulating cam tightens the dropper.

[0052] When the infusion is finished, if the photoelectric sensor cannot detect the droplets, a signal will be given, and the single chip microcomputer controls the buzzer 71 to work and emit a dripping sound alarm. At this time, the medical staff can turn off the buzzer 71 by pressing a button, and then take down the entire instrument, and the infusion process is finished.

[0053] Embodiment 2:

[0054] In addition, in order to further ensure the convenience of using the portable infusion drip rate display instrument and the accuracy of counting drops, this embodiment adds a fixed cover 9 on the basis of the portable infusion drip rate display instrument proposed in Example 1. Figure 5 As shown, in the present embodiment, the fixed cover 9 is a flip cover structure, that is, one side of the fixed cover 9 is movably connected to the edge of one side of the shell 1 of the portable infusion drop rate display instrument (similar to the flip cover structure of a food box), so that the fixed cover 9 can rotate along the edge in contact with the box body 1 as the axis, and the other side is fixedly locked with the edge of the shell 1 by a locking buckle (not shown in the figure), so that when the fixed cover 9 is in the closed state, the fixed cover 9 can be locked with the box body 1. At this time, the entire portable infusion drop rate display instrument can be directly hung on the infusion tube without being fixed.

[0055] In addition, the movable connection mode of the fixed cover 9 and the side of the box body 1 contacting the edge includes but is not limited to the above-mentioned mode, and can also be other movable connection modes. For example, it is also possible to connect by hinge. In addition, the inner side of the fixed cover 9 is provided with the same dropper accommodating groove 8 as in the above-mentioned embodiment 1, so that when the fixed cover 9 is in the covered state, the entire portable infusion drip rate display instrument can just wrap the drip pot and the dropper inside.

[0056] Furthermore, in order to solve the problem of wind interference or the patient accidentally touching the infusion tube during activities, thereby causing the droplets to fall faster, a preferred method is to provide a Velcro or other fixing buckle (not shown in the figure) on the outer surface of the above-mentioned fixed cover 9. The Velcro or fixing buckle can be used to quickly fix the portable infusion drop rate display on the infusion stand or other structures in the infusion environment. At this time, the drip rate of the droplets in the infusion tube will be avoided as much as possible from being disturbed by the external environment, thereby ensuring the accuracy of the drop counting technology.

[0057] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0060] 3.
