Description

Technical Field

[0001] The invention belongs to the technical field of nursing heating appliances, and in particular relates to a nursing pain relief device. Background Art

[0002] In clinical nursing work, in order to relieve patients' pain, medical staff need to apply hot compresses or massage the painful areas to relieve the pain. Based on the principle of heat conduction, heat is transferred to specific parts of the body to dilate local blood vessels, which can speed up blood circulation. On the one hand, it brings more oxygen and nutrients to the tissues, and on the other hand, it helps to take away metabolic waste, thereby relieving muscle spasms, reducing pain, and relaxing tense muscles.

[0003] Patent announcement number CN115844625A proposes a pain relief device for nursing. In this patent, a hot water bag is powered on and heated in advance for hot compress. The water temperature distribution inside the electric hot water bag is not uniform. The temperature of the area close to the heating element will be higher, while the temperature of the position far from the heating element will be lower. This hot compress method makes the temperature distribution uneven, affecting the effect of the hot compress. In addition, a massage mechanism is provided in this patent to assist the patient in relieving pain. However, when the massage mechanism is in use, in order to avoid the hot water bag from being squeezed, the massage mechanism and the hot water bag need to be staggered, which affects the hot compress area of ​​the hot water bag, making the hot compress discontinuous and affecting the effect of the hot compress.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Through the circulating hot compress mechanism, temperature control mechanism and PLC controller, circulating water can be used as heat transfer for hot compress. Compared with the uneven temperature of traditional electric hot water bags, the water circulates continuously in the device, which can ensure that the temperature is evenly distributed in the entire hot compress area. Because the hot water can be fully mixed during the circulation process, the temperature of each part of the skin contacted by the hot compress device is basically the same, which provides a stable and uniform warm environment for the body, is more conducive to promoting local blood circulation and relaxing muscles, and can quickly adjust the initial temperature of the hot compress. For patients with more severe pain, such as severe muscle strain, a relatively high temperature is set. Temperature can relieve pain. Higher temperatures can more effectively promote blood circulation, speed up local metabolism, and help relax tense muscle fibers. For patients with mild pain, the set temperature is relatively low, which can not only relax muscles, but also will not cause discomfort due to excessively high temperatures. It can also automatically adjust the speed of subsequent temperature reduction based on the initial temperature. The higher the initial temperature, the faster the temperature drops. Avoiding excessively high temperatures and slow drops will cause the local skin to be in a high temperature environment for a long time, increasing the risk of burns. It is also better adapted to patients with severe muscle strains because their skin will become more sensitive after injury and their tolerance to temperature will decrease, thus confirming the quality of treatment.

[0022] 2. Through the vibration massage mechanism, power supply mechanism and PLC controller, the circulating flow power in the hot compress process can be used to synchronously provide the vibration massage function, which saves energy and is easy to operate. The vibration massage can help relax tense muscle fibers and assist the hot compress to further improve local blood circulation. The intensity of the vibration massage is automatically adjusted based on the relief needs. When the initial muscle strain is more serious, a smaller vibration massage intensity is used to avoid the problem that excessive vibration massage intensity will further damage the muscles. As the hot compress work progresses, after the muscle injury is alleviated, the intensity of the vibration massage is automatically increased to speed up the recovery process. The massage function does not conflict with the hot compress function, ensuring the hot compress area and continuity.

[0023] 3. Through the set lifting and separation mechanism, lifting frequency control mechanism and PLC controller, the hot compress bag can be separated from the patient's skin at intervals during the hot compress process, avoiding the problem of long-term continuous contact with the skin by the hot compress bag, which will gradually accumulate heat and cause burns. It also avoids the problem that continuous hot compress will cause excessive expansion of local blood vessels at the hot compress position of the patient, thereby leading to local congestion and aggravated edema. The interval separation hot compress belt can give the blood vessels time to restore normal tension and avoid the adverse effects of excessive blood vessel expansion. It can also automatically adjust the frequency of separation of the hot compress bag from the patient's skin based on the hot compress temperature. The higher the hot compress temperature, the higher the separation frequency. Because the higher the hot compress temperature, the greater the risk of skin burns, the faster the skin loses water and the barrier function is damaged, and the local blood vessels are more likely to over-expand and the heat accumulates more quickly. Therefore, the frequency of interval separation needs to be higher to avoid these adverse effects. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the control shell 71 is provided with a limit slide groove that matches and slides with the limit slider.

[0039] The PLC controller 8 is fixedly mounted on the upper end of the base 1 and is electrically connected to the circulating hot compress mechanism 2, the temperature control mechanism 3, the vibration massage mechanism 4, the power supply mechanism 5, the lifting and separation mechanism 6 and the lifting frequency control mechanism 7 respectively.

[0040] The operating principle of the present invention is described as follows: the hot compress bag 21 is placed at the position where the patient needs hot compress, and is fixed by two elastic straps 29 and the Velcro round hair layer 210 and the Velcro pointed hair layer 211 thereon, so that the hot compress bag 21 is stably applied to the hot compress position of the patient, the PLC controller 8 controls the electric heating rod 23 and the circulation pump 25 to work, the electric heating rod 23 heats the circulating water in the heating shell 22 to a preset temperature, the circulation pump 25 cooperates with the circulation pipe 24 to transport the heated water to the hot compress bag 21, and the heat is transferred to the hot compress part of the patient's body through the hot compress bag 21, so that the local blood vessels are dilated and the blood circulation is accelerated, thereby relieving muscle spasms, alleviating pain, and relaxing tense muscles;

[0041] The temperature adjustment knob 31 is manually adjusted in advance according to the patient's muscle injury fatigue degree, and the temperature adjustment knob 31 is turned to the preset temperature position through the cooperation of the pointer 33 and the arc-shaped temperature scale plate 32. The temperature adjustment knob 31 cooperates with the PLC controller 8 to control the electric heating rod 23 to heat the circulating water to the preset temperature [when the temperature adjustment knob 31 is turned, it will generate an analog signal (such as a change in voltage or resistance value). This signal represents the target temperature set by the user. In the PLC controller 8, there is a special analog input module, which can convert the analog signal generated by the temperature adjustment knob 31 into a digital signal. For example, a 0-10V voltage signal is converted into a digital value of 0-4095 (for an analog input module with a 12-bit resolution), and this digital value corresponds to the temperature range set by the user]. The temperature is initially set. After the hot compress is applied for 5 minutes, the PLC controller 8 controls the electric push rod 35 to push the stepper motor 36 to move, so that the driving gear 37 at the output end of the stepper motor 36 meshes with the driven gear 38 on the temperature adjustment knob 31, and the PLC controller 8 controls the stepper motor 36 to drive the driving gear 37 to move, thereby driving the temperature adjustment knob 31 to reverse, so that the hot compress temperature gradually decreases, avoiding the problem of scalding the patient due to the hot compress temperature being too high, and the PLC controller 8 automatically adjusts the driving speed of the stepper motor 36 based on the temperature signal fed back by the initial temperature adjustment knob 31. The higher the initial temperature, the higher the speed of the stepper motor 36, and the faster the temperature drops, until the hot compress temperature drops to 35°C. At this time, the PLC controller 8 controls the stepper motor 36 to stop moving until the hot compress time reaches 30 minutes, completing a hot compress job;

[0042] When performing hot compress, the PLC controller 8 controls the action of the electric-controlled flap valve 54 on the water inlet multi-way pipe 53. Specifically, when the initial patient's muscle damage is greater and the hot compress temperature is higher, the PLC controller 8 controls the electric-controlled flap valve 54 to open at a smaller angle based on the temperature signal. A small portion of water flows from the water outlet of the circulation pipe 24 through the water inlet multi-way pipe 53 into the multiple power shells 51, thereby driving the water wheel 52 to rotate. The water wheel 52 drives the transmission shaft 46 to drive the cam 47 to rotate synchronously. When the protrusion of the cam 47 squeezes the impact plate 43, the impact plate 43 drives the impact rod 42 to overcome the elastic force of the reset spring 44 and impact on the force plate 27, thereby transmitting the impact force to the massage ball through the support rod 26. 28, and when the protruding part of the cam 47 leaves the impact plate 43, the impact rod 42 is reset under the action of the reset spring 44, thereby realizing continuous impact, providing additional vibration massage function, and assisting better hot compress work. In addition, since the opening angle of the electric-controlled flap valve 54 is small and the water flow inflow is small, the rotation speed of the water wheel 52 is relatively slow, thereby making the vibration massage intensity smaller. On the contrary, when the patient's muscles are better relieved as the hot compress work progresses, the hot compress temperature also decreases synchronously at this time. The PLC controller 8 controls the electric-controlled flap valve 54 to open at a larger angle, so that there is more circulating water flow to drive the water wheel 52 to rotate, so that the rotation speed of the water wheel 52 is increased, the vibration massage intensity is increased, and the patient's replacement recovery is assisted;

[0043] When performing hot compress, the PLC controller 8 controls the reduction motor 73 to move synchronously, and the reduction motor 73 drives the reciprocating screw 72 to rotate. The threaded connection between the reciprocating screw 72 and the trigger plate 74 enables the trigger plate 74 to move in the control shell 71 until the trigger plate 74 presses on the trigger switch 75. At this time, the PLC controller 8 first controls the reduction motor 73 to stop moving, and controls the lifting and separation mechanism 6 to move synchronously. The electric telescopic rod 62 pushes the rubber support block 63 downward, so that the rubber support block 63 contacts the hot compress part of the patient, and then the hot compress bag 21 is relatively lifted, so that the hot compress bag 21 is separated from the patient's skin, avoiding the problem that the hot compress bag 21 continues to contact the skin for a long time, the heat will gradually accumulate and cause burns, and also avoids the problem that continuous hot compress will cause local blood vessels at the hot compress part of the patient. Overexpansion leads to the problem of local congestion and aggravated edema. The interval separation hot compress belt can give the blood vessels time to restore normal tension and avoid the adverse effects of excessive blood vessel expansion. The lifting time is maintained for 10 seconds. After 10 seconds, the PLC controller 8 controls the electric telescopic rod 62 to drive the rubber support block 63 to reset and move. Under the elastic return action of the elastic strap 29, the hot compress bag 21 contacts the patient's skin again for hot compress work. At this time, the PLC controller 8 controls the reduction motor 73 again to perform the next stage of lifting and separation triggering action. The PLC controller 8 automatically adjusts the speed of the reduction motor 73 based on the hot compress temperature signal. The higher the hot compress temperature, the faster the speed of the reduction motor 73, thereby shortening the interval time for the trigger switch 75 to be pressed and triggered, and increasing the frequency of lifting and separation.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
