Description

Technical Field

[0001] The utility model relates to the field of infusion set alarms, in particular to an infusion set with an alarm. Background Art

[0002] An infusion set is a common medical consumable. After being aseptically processed, a channel is established between the vein and the drug solution for intravenous infusion. After the infusion is completed, if the needle is not removed in time, blood reflux may occur. In order to avoid this situation, an infusion set with an alarm is needed. Among them, the "an auxiliary alarm device based on an infusion set" disclosed in the application number "CN202220626501.0" is also an increasingly mature technology. It "due to the fact that drug solutions usually need to be stored at low temperatures and have a large specific heat capacity, there is an obvious temperature difference between the infusion set body containing drug solutions and the infusion set body not containing drug solutions. By setting an infusion auxiliary alarm component, compared with the prior art, when the device is fixed on the infusion set body, the infusion set body The temperature sensor is in contact with the infusion set body, and the temperature sensor monitors the temperature of multiple positions of the infusion set body. When the infusion set body contains liquid medicine, the temperature difference of multiple positions monitored by the temperature sensor is constant. By monitoring the temperature difference, the function of monitoring and alarming the infusion is realized, which can effectively avoid the possibility of non-alarm or false alarm. However, the infusion set still has the following defects during use: the infusion set can indeed detect the temperature of the liquid medicine first and have an alarm effect through the temperature sensor, but the infusion tube is long, and the temperature difference of the liquid medicine in the same medicine bottle is small, which may lead to monitoring omissions. Based on this, it is necessary to provide an infusion set that can accurately detect the output of liquid medicine and alarm in time. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. When the patient is receiving an infusion, the liquid medicine in the medicine bottle is first transported into the patient's vein through the connecting tube, the liquid storage tube and the infusion tube. When the liquid medicine passes through the connecting tube, the capacitor A plate cooperates with the capacitor B plate to detect the liquid medicine passing through and transmits the information of the existence of the liquid medicine to the photoelectric alarm through the sensor. When there is still liquid medicine passing through the connecting tube, the photoelectric alarm blocks the alarm. After the liquid medicine in the medicine bottle is transported and no liquid medicine passes through the connecting tube, the capacitor A plate and the capacitor B plate cannot detect the existence of the liquid medicine, and the photoelectric alarm cannot receive the reflected light information, so an alarm operation is performed to remind medical staff to replace it. Compared with the infusion set in the prior art "an auxiliary alarm device based on an infusion set", the utility model can accurately detect the liquid medicine through the cooperation of the above structures, and can promptly perform an alarm operation after the infusion is completed, thereby improving the safety of the infusion set;

[0017] 2. When the patient is receiving an infusion, the medicine in the medicine bottle passes through the connecting tube, the storage tube and the infusion tube and enters the patient's vein. At this time, the ultrasonic oscillator cooperates with the ultrasonic generator to emit high-frequency ultrasonic waves, and the emitted ultrasonic waves are blocked by the medicine passing through the connecting tube. Therefore, the ultrasonic receiver cannot receive the ultrasonic waves, and thus the alarm operation cannot be performed. When the infusion is completed, no medicine passes through the connecting tube. At this time, the high-frequency sound waves generated by the ultrasonic generator and the ultrasonic oscillator pass through the connecting tube and are received by the ultrasonic receiver. Therefore, the buzzer can sound an alarm to remind medical staff to change the medicine. Compared with the alarm structure that cannot perform accurate alarm in the prior art "an auxiliary alarm device based on an infusion set", the utility model can accurately detect the medicine through the cooperation of the above-mentioned structures, so as to facilitate timely alarm operation, thereby improving the safety of the use of the infusion set.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] See also Figure 1-5 The utility model provides an infusion set with an alarm, comprising an infusion assembly 100, a first alarm assembly 200 and a second alarm assembly 300;

[0026] The infusion assembly 100 includes an infusion tube 101, a liquid blocker 102 is installed on the side surface of the infusion tube 101, a liquid blocker wheel 103 is rotatably installed inside the liquid blocker 102, a liquid storage tube 104 is detachably installed on the upper end of the infusion tube 101, a connecting tube 105 is connected to the upper end of the liquid storage tube 104, a puncture tube 106 is movably installed on the upper end of the connecting tube 105, and an infusion needle 107 is provided at the lower end of the infusion tube 101;

[0027] The first alarm component 200 includes a mounting shell 201 mounted on the side surface of the connecting pipe 105, a photoelectric alarm 202 and a sensor 203 are mounted inside the mounting shell 201, a first induction clip 204 and a second induction clip 205 are hinged on one side of the mounting shell 201, and a capacitor A plate 206 and a capacitor B plate 207 are mounted inside the first induction clip 204 and the second induction clip 205;

[0028] The second alarm assembly 300 is mounted on the side surface of the connecting pipe 105 .

[0029] In a specific embodiment, the infusion component 100, the first alarm component 200 and the second alarm component 300 can accurately detect the drug solution by means of photoelectric alarm or ultrasonic alarm, and perform real-time automatic alarm operation to remind medical staff to replace the drug solution, thereby improving the safety of the infusion device. When in use, the patient is first injected into the artery through the infusion tube 101, the storage tube 104 and the connecting tube 105. At this time, when the drug solution in the medicine bottle passes through the connecting tube 105, the capacitor A plate 206 cooperates with the capacitor B plate 207 to The medicine liquid in the connecting tube 105 is detected, and the information of the medicine liquid passing through the connecting tube 105 is transmitted to the photoelectric alarm 202 through the sensor 203. When there is medicine liquid in the connecting tube 105, the photoelectric alarm 202 is blocked and alarms. When the infusion is completed and no medicine liquid passes through the connecting tube 105, the capacitor A plate 206 and the capacitor B plate 207 cannot detect the presence of the medicine liquid, so that the photoelectric alarm 202 cannot receive the reflected light information. Therefore, an alarm operation can be performed to remind medical staff to replace the medicine liquid in time, thereby improving the convenience of using the infusion device.

[0030] See also Figure 2 The upper end of the infusion needle 107 is fixedly connected to a first connector 111, which is inserted into the inside of the infusion tube 101. The lower end of the puncture tube 106 is fixedly connected to a second connector 112, which is inserted into the inside of the connecting tube 105.

[0031] In a specific embodiment, the first connector 111 and the second connector 112 facilitate connecting the infusion needle 107 and the puncture tube 106 to the infusion tube 101 and the connecting tube 105 respectively, so as to facilitate infusion operation and disassembly.

[0032] See also Figure 2 The upper end of the infusion tube 101 and the lower end of the connecting tube 105 are respectively fixedly connected with a first sealing head 121 and a second sealing head 122 , and the first sealing head 121 and the second sealing head 122 are both sealed and connected to the inside of the liquid storage tube 104 .

[0033] In a specific embodiment, the first sealing head 121 cooperates with the second sealing head 122 to improve the sealing performance of the connection between the connecting tube 105 and the infusion tube 101 and the liquid storage tube 104, thereby preventing leakage of the drug solution.

[0034] See also Figure 3 A hinge shaft 211 is installed on one side of the first induction clamp 204 and the second induction clamp 205, and a hinge tube 212 is connected to one side of the mounting shell 201. The hinge shaft 211 and the hinge tube 212 are hinged to each other, and the first induction clamp 204 and the second induction clamp 205 are connected by a torsion spring.

[0036] See also Figure 3 A switch button 221 is electrically connected to the surface of the second sensing clip 205 , and two sensing lamps 222 are embedded inside the second sensing clip 205 .

[0037] In a specific embodiment, the switch button 221 can be used to control the opening and closing of the first alarm component 200. When the sensor light 222 is on, the alarm operation can be performed, and when the sensor light 222 is off, the alarm can be stopped.

[0038] Example 2

[0039] The difference between this embodiment and the existing embodiment 1 is that the second alarm component 300 includes a first protective shell 301 and a second protective shell 302 installed on the side surface of the connecting pipe 105, and an ultrasonic generator 303 and an ultrasonic receiver 304 are installed inside the first protective shell 301 and the second protective shell 302 respectively, and ultrasonic oscillation plates 305 are installed on the opposite surfaces of the first protective shell 301 and the second protective shell 302, and a buzzer 306 is installed on the upper end of the first protective shell 301.

[0040] In a specific embodiment, when in use, the ultrasonic oscillator 305 cooperates with the ultrasonic generator 303 to emit high-frequency sound waves. At this time, the ultrasonic waves are blocked by the liquid medicine in the connecting tube 105, so that the ultrasonic receiver 304 cannot receive the ultrasonic waves, and thus the alarm operation cannot be performed. When the infusion is completed, there is no liquid medicine in the connecting tube 105. At this time, the high-frequency sound waves generated by the ultrasonic generator 303 and the ultrasonic oscillator 305 pass through the connecting tube 105 and are received by the ultrasonic receiver 304, so that the buzzer 306 can sound an alarm, promptly reminding medical staff to replace the liquid medicine, thereby improving the convenience of using the infusion device.

[0041] See also Figure 5 The opposite sides of the first protective shell 301 and the second protective shell 302 are both provided with mounting grooves 311, and the ultrasonic generator 303 and the ultrasonic receiver 304 are both installed inside the mounting grooves 311. The opposite sides of the first protective shell 301 and the second protective shell 302 are both provided with fixing grooves 312, and the ultrasonic oscillator 305 is installed inside the fixing grooves 312.

[0042] In a specific embodiment, the installation groove 311 can install and protect the ultrasonic generator 303 and the ultrasonic receiver 304, and the fixing groove 312 can limit and fix the ultrasonic oscillation plate 305 so that the ultrasonic oscillation plate 305 and the connecting pipe 105 are in contact to facilitate real-time monitoring.

[0043] See also Figure 5 A folding piece 321 is threadedly connected between the first protective shell 301 and the second protective shell 302 . A connecting groove 322 is opened at the upper end of the first protective shell 301 . The buzzer 306 is electrically connected inside the connecting groove 322 .

[0044] In a specific embodiment, the existence of the folding piece 321 facilitates the control of the opening and closing of the first protective shell 301 and the second protective shell 302 , and the connecting groove 322 facilitates the installation and fixation of the buzzer 306 .

[0045] Working principle: When performing an alarm operation, the capacitor A plate 206 cooperates with the capacitor B plate 207 to detect the liquid medicine passing through the connecting tube 105, so that the information of the liquid medicine passing through the connecting tube 105 can be transmitted to the photoelectric alarm 202 through the sensor 203. When there is liquid medicine in the connecting tube 105, the photoelectric alarm 202 is blocked and alarms are sounded. When no liquid medicine passes through the connecting tube 105 after the infusion is completed, the capacitor A plate 206 and the capacitor B plate 207 cannot detect the existence of liquid medicine, so that the photoelectric alarm 202 cannot receive the reflected light information, and thus can perform a real-time alarm operation;

[0046] When performing an alarm operation, the ultrasonic oscillator 305 cooperates with the ultrasonic generator 303 to emit high-frequency sound waves. The ultrasonic waves are blocked by the liquid medicine in the connecting tube 105, so that the ultrasonic receiver 304 cannot receive the ultrasonic waves, and therefore the alarm operation cannot be performed. After the infusion is completed, there is no liquid medicine in the connecting tube 105. The high-frequency sound waves generated by the ultrasonic generator 303 and the ultrasonic oscillator 305 pass through the connecting tube 105 and are received by the ultrasonic receiver 304, so that the buzzer 306 can sound an alarm, thereby achieving the purpose of timely reminding medical staff to replace the liquid medicine and improving the safety of use.
