Description

Medical injection detection warning device

The present invention relates to a medical injection detection warning device suitable for use in a IV precision infusion sleeve metering cylinder (IV Bag), which sends a warning message to detect medical treatment or spotting to remind the medical staff to handle.

Infusion therapy refers to the direct infusion of water, nutrients or drugs to provide life-sustaining functions. It is one of the current medical measures. Intravenous injection is a clinically and generally invasive treatment for blood, infusion and drug treatment. However, clinically, when encountering difficult intravenous problems, it not only affects the timeliness of treatment, but also the injections can cause pain and anxiety, increase the risk of complication such as injection infection, consume nursing hours and costs, and cause pressure on medical staff. . Intravenous infusion procedures should be carried out to evaluate and care the use of the pipeline. When the infusion is running (whether continuous or intermittent), the peripheral venous catheter site should be regularly evaluated for redness, tenderness, swelling or paresthesia, numbness or tingling. Sense, to improve the safety of the pipeline placement to reduce the related damage.

Internal medicine patients often need to be treated with intravenous infusion of antibiotics or small doses due to disease factors. The incidence of comorbidities caused by the retention of peripheral intravenous infusion catheters is about 22.5%, and the incidence of catheter obstruction accounts for 6-8%. The common cause is : (1) Blood clot or fibrin formation: the height of the infusion solution bottle is less than 50-90 cm, dripping after dosing or dropping the drip bottle, causing the blood to block the diameter; (2) Mechanical factors: the catheter connector is loose, Compression and distortion, etc.; (c) Chemical factors: the use of incompatible drugs to produce crystals, resulting in blockage of the pipeline. Once the venous catheter occlusion occurs, not only the number of intravenous catheter injections and the psychological fear of the patient are increased, but also the continuity and effect of the treatment are affected, and more nursing costs are also consumed.

The difficulty in grasping the progress of intravenous infusion is a common problem that has always caused the burden on medical staff. Clinical care is often caused by improper follow-up of intravenous infusion control, such as re-rinsing the tubing or even placing a new intravenous catheter. These factors will increase the nursing time. number. In busy clinical care work, it is necessary to keep abreast of the patient's dynamics and find out the care problems in time and deal with them as soon as possible. With the development of technology, intravenous drug flow rate monitoring can be improved by remote observation function. However, in addition to ensuring stable operation of the system, it is important to ensure that the message is delivered to the user correctly, immediately and efficiently.

Inpatients often need small doses of infusion to treat patients with diseases. When the doctor opens a doctor's order, the medical staff needs to establish a peripheral intravenous infusion line. According to the time, route and dose of the drug, the drug is added to the IV infusion sleeve. In the IV bag, adjust the drip rate. The current situation is that the medical staff needs to estimate the time of drug drop and then go to the treatment. When the injection of the drug in the IV bag is completed, the medical staff will need to The metering cylinder connects a large number of drip tube clips to open and close the air guiding holes, and adjusts the amount of liquid in the IV bag to 10-15 ml, and then instills it into the patient from a large number of intravenous infusion lines.

The average ward care ratio of the medical staff in the general ward is 1:9. During the intravenous infusion, the responsible nurse will patrol the patient according to the estimated time of instillation, but sometimes he will forget to go to the hospital because he is just treating the bed patient. The drug has been instilled for a long time, the family found that the drip is not dripping or returning to the blood before calling the nurse; and the inpatients are mostly elderly care for the elderly, vision and physical strength are limited, these people can not always pay attention to dosing due to age or physical strength In the case of drip, it is often the case that the venous indwelling needle is blocked and needs to be re-injected, which not only increases the medical cost, the labor cost, but also affects the patient's comfort and complaints.

In order to improve the above situation, the medical staff through the feedback of work experience, they hope that there will be a reminder device when the drug is about to be dripped, to remind the medical staff to go to the treatment.

There are various related related intravenous warning devices, such as the Mikodrip drip monitoring system made in China, which can detect the weight change of the IV bag, and the drip bag is hung under the system during use, but The method can only detect whether the whole bag is dripped or not, and can not be used in the measuring tube (IV Bag) for detecting the drug and adding it to the intravenous infusion sleeve.

Another conventional Chinese-made infusion reminder is a light-detecting warning device, which is used to plug a drip pipe to the left side of the light-detecting warning device, and to alert when a pipe is detected to have air. sound. The shortcoming of the light detecting device is that when the air is detected in the pipeline, the representative droplet has been dripped, and it is too late to detect the drip. In addition, the same problem is added to the medicine, so that the medical staff can respond to the time. insufficient.

Another Japanese-made FLOW SIGN II is also a light-detecting warning device that is used to insert a drip bag into it to detect the speed of the drip, and to sound a warning when there is a change. The shortcoming of the light detecting warning device is that it can only detect the change of the drip speed above the drip bag, and the medicine can not be detected when it is added to the bag, so it is not suitable for the dosing of the drip bag.

In addition, the drip alarm disclosed in Taiwan Patent No. M546825 sets a liquid sensor on a first jig, and a drip infusion tube is interposed through the first jig to detect the liquid medicine in the infusion tube; The module, the warning module and the wireless transmission module are disposed on a second clamp to clamp the second clamp on the drip stand. The structure is more complicated and less convenient to use.

Furthermore, the spot sensor disclosed in Taiwan No. M540658 is to mount a detector on the sub-dropper bottle, and the detector is electrically connected to the sounding device by a wire, and the sounding device includes a buzzer and a a circuit board, wherein the buzzer is electrically connected to the circuit board; when the drip in the sub-dropper bottle is about to be used, the detector can notify the sounding device to make the buzzer sound, but the drip sensor is subject to Fluorescent lights, sunlight, and other light sources interfere with the operation of the receiver.

The battery chamber 31 may be disposed at the first clamping portion 11 or the second clamping portion 12, and the conductive elements provided in the battery chamber 31 are electrically connected to the control circuit 2. Based on the optimal configuration considerations, when the control circuit 2 is disposed on the first clamping portion 11, the battery chamber 31 is also disposed at the first clamping portion 11, and when the control circuit 2 is disposed at the second clamping portion 12, the battery chamber 31 is also provided at the second clamping portion 12, whereby the conductive connection structure between the battery unit 3 and the control circuit 2 can be simplified.

The light emitting module 5 may be disposed on the first clamping portion 11 or the second clamping portion 12 and electrically connected to the control circuit 2 to be controlled to emit a concentrated linear beam; in other words, when the light emitting module 5 is disposed In the first clamping portion 11, the LED light source 51 emits light in the direction of the second clamping portion 12; when the light emitting module 5 is disposed in the second clamping portion 12, the LED light source 51 is tied to the second clamping portion The direction of the portion 11 emits light.

The light receiving module 6 and the light emitting module 5 are disposed at positions that are not linearly corresponding to each other, that is, the light receiving module 6 and the light emitting module 5 are disposed on the opposite sides of the first clamping portion 11 and the second When the clamping portion 12 is clamped, the light receiving module 6 and the light emitting module 5 are offset from each other by an appropriate distance; more specifically, the appropriate distance of the deviation is a relatively large beam radius generated by the light beam B passing through the air. The difference in the relatively small beam radius produced by beam B after passing through the drug solution. As shown in FIG. 9A and FIG. 9B, in which, based on the foregoing setting, FIG. 9A shows that the beam B passes through the drug solution L to produce a relatively small beam diameter that does not cover the light sensing element 61, so that the beam cannot be illuminated by the photo sensing element. 61 is sensed; FIG. 9B shows that beam B passes through the air to produce a relatively large beam diameter to encompass light sensing element 62 such that the beam can be sensed by light sensing element 61.

Since the foregoing control circuit 2, the power supply unit 3, the light emitting module 5, the light receiving module 6, the optical filter module 7, and the warning module 8 are disposed on the clamp 1, the first and second clamping portions 11 may be The weight of the free end of 12 and the first and second force applying ends 111, 112 are not uniform, so that it may be inconvenient to operate when the jig 1 is operated. Therefore, when the weights of the first and second force applying ends 111, 112 are larger than the first and second holding portions At the free end of 11, 12, the creation can further provide a weight 14 (shown in Figure 6) at the two free ends so that the two ends of the clamp 1 can be balanced. Alternatively, the present creation can also set the power supply unit 3 to have two sets of batteries, and equally distribute the first and second holding portions 11, 12 to balance the entire jig 1.

3A and FIG. 3B are schematic plan cross-sectional views showing the first clamping portion 11 and the second clamping portion 12 of the present invention sandwiching the IV catheter metering cylinder T; FIG. 4 is a view showing the first clamping of the present invention. The portion 11 and the second clamping portion 12 sandwich the intravenous infusion tube metering cylinder T and detect the liquid level of the liquid medicine L; and FIG. 5 shows the liquid level L of the liquid medicine in the metering cylinder of FIG. A schematic diagram that was detected after a certain degree. As shown in FIG. 3A and FIG. 4, the medical injection detecting and warning device of the present invention is used to clamp the first clamping portion 11 and the second clamping portion 12 of the clamp 1 to an intravenous infusion sleeve. The opposite sides of the cylinder T, and the power supply unit 3 is activated to enable the light emitting module 5 to emit a light beam B through the intravenous infusion sleeve metering cylinder T and the liquid medicine L contained therein, and then enter the light receiving module 6 At this time, the beam diameter is reduced due to the refraction of the light beam B when it penetrates the liquid , so that the light sensor 61 of the light receiving module 6 that is offset by a distance cannot sense the light beam (as shown in FIG. 9A), and passes through the control circuit. 2 The warning module 8 is driven to emit no warning information such as sound or/and light. As shown in FIG. 3B and FIG. 5, when the liquid medicine falls below the height of the emitted light beam B, the light beam B is not interfered by the liquid medicine L in the intravenous infusion sleeve metering cylinder T and directly passes through the air and is relatively large. The beam diameter, the beam diameter covers the light receiving module 6 so that the light can enter the photo sensor 61, so that the warning module 8 is driven by the control circuit 2 to emit warning information such as sounds and/or lights. In other words, the medical staff can clamp the first and second clamping portions 11 and 12 of the clamp 1 at an appropriate height position outside the intravenous infusion cannula cylinder T according to actual needs, and the medicine in the intravenous infusion cannula measuring cylinder T When the liquid L level is higher than the height of the light beam B emitted by the light emitting module 5, the light beam B is refracted and diverged by the liquid when entering the liquid L through the intravenous infusion sleeve metering cylinder T, so that the light beam B is interfered. However, the light receiving module 6 cannot be accessed, so the warning module 8 does not move, and no warning information such as sound or light can be emitted. When the liquid level L in the intravenous infusion cannula cylinder T drops below the height of the beam B emitted by the light emitting module 5, the beam B passes directly into the light receiving mode through the intravenous infusion sleeve metering cylinder T. In the group 6, the light receiving module 6 drives the warning module 8 to activate the warning module 8 to emit a warning message such as a sound or a light, and the medical staff can immediately take the subsequent processing loss when receiving the warning information.

The present invention simplifies the overall detection and warning device by integrating the control circuit 2, the power supply unit 3, the light-emitting module 5, the light-receiving module 6, the optical filter module 7, and the warning module 8 on a fixture 1. Structure, more convenient to use.

FIG. 8 shows another embodiment of the present invention. A processor 4 and a communication module 9 can be further electrically connected to the control circuit 2; wherein the processor 4 is further configured to process the control power unit 3 and emit light. The cooperative operation function between the module 5, the light receiving module 6, the optical filtering module 7 and the warning module 8; the processor 4 is also referred to as a central processing unit (CPU).

The communication module 9 can transmit whether the warning module 8 sends a warning message to a remote device (not shown), and the medical staff or the patient's family can monitor the patient through the remote device at a remote location. The liquid level of the intravenous drug solution does not need to be kept beside the patient or pay attention to the drip condition. The remote device can be a computer device or a handheld device (eg, a mobile phone, a tablet).
