Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic nursing, in particular to a cold compress device for orthopedic nursing. Background Art

[0002] In orthopedic care, cold compresses are an important means of alleviating postoperative swelling and pain, particularly in the early recovery phase after traumatic surgeries such as fractures and joint replacements. Currently, commonly used cold compress devices for orthopedic care are often limited to a single cooling effect, making them incapable of meeting the diverse needs of patients during their recovery.

[0003] Existing devices typically have a simple design, consisting of a bag or rigid shell containing a refrigerant (such as an ice pack or cold gel). They achieve cooling by directly contacting the affected skin. To secure the device in place, some products incorporate elastic straps or Velcro. However, the tightness of these straps is adjusted at the discretion of the healthcare provider or patient. Overtightening can impede local blood circulation, while overly loosening can cause the device to shift, impacting the stability of the cold compress.

[0004] From a functional perspective, these devices can only reduce the temperature of the affected area through the physical absorption of heat by the refrigerant, and cannot simultaneously provide other auxiliary care functions. For example, during the cold compress process, patients often feel discomfort due to the prolonged cold exposure of the local skin, and may even risk frostbite.

[0005] In summary, the existing cold compress devices for orthopedic care have gradually become unable to meet the efficient, safe and personalized rehabilitation needs in modern orthopedic care due to their single function, and there is an urgent need for a cold compress device for orthopedic care. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a cold compress device for orthopedic care.

[0007] To achieve the above object, the technical solution adopted by the present invention is:

[0008] A cold compress device for orthopedic care comprises a nursing seat provided with a nursing mechanism.

[0009] Preferably, the nursing mechanism includes a nursing tube, and a rack is provided in an annular shape along the outer wall of the nursing tube, and the rack is meshed and connected with a transmission wheel.

[0010] Preferably, the outer wall of the nursing cylinder is detachably connected to a spraying mechanism, and the spraying mechanism includes a storage bin, and the storage bin is connected to the nozzle through an electric telescopic tube.

[0011] Preferably, an air storage tank is provided in a ring shape along the outer wall of the nursing tube, an air pump is provided inside the air storage tank, the air pump is connected to the solenoid valve through an air pipe, the solenoid valve is connected to the air bag away from the air pump, the air bag is arranged in a ring shape on the inner wall of the nursing tube, and the solenoid valve passes through the outer wall of the nursing tube.

[0012] Preferably, an ice compress is detachably connected to a side of the airbag away from the solenoid valve, and the airbag is provided with a pressure sensor, which is electrically connected to the solenoid valve.

[0013] Preferably, the nursing seat is threadedly connected to an electric telescopic rod, the electric telescopic rod is connected to the nursing cylinder via a connecting block, and the connecting block is slidingly connected to the nursing cylinder.

[0014] Preferably, an arc-shaped electric heating plate is embedded in the nursing cylinder.

[0015] Preferably, the nursing seat is provided with a side groove, the inner wall of the side groove is connected to one end of the elastic belt, and any two of the elastic belts are connected by a buckle.

[0016] Preferably, a support block is provided at the bottom of the nursing seat, and the support block is slidably connected to the outer wall of the nursing tube.

[0017] Preferably, a driving motor is further provided at the bottom of the nursing seat, and an output end of the driving motor is connected to a transmission gear.

[0018] The beneficial effects of the present invention are:

[0019] This application provides an injection mechanism on the outer wall of the nursing tube, and fills the filling chamber with corresponding medicine according to the orthopedic care situation. The cold compress and spray dual modules work together to break through the technical limitations of a single cold compress.

[0020] The synergy of the super-cold compress and spray modules can improve the permeability of drugs. The formation of an ice crystal protective layer by spraying after the cold compress can reduce the probability of frostbite in patients. Compared with traditional ice compress devices, this application can be flexibly adjusted for various nursing situations.

[0021] An airbag is provided in a ring shape on the inner wall of the nursing tube, a cold compress belt is provided on the airbag, the expansion degree of the airbag is dynamically adjusted by an air pump and a solenoid valve, and a pressure sensor is provided on the airbag. Compared with traditional ice compress devices that can only provide a single cold compress effect, this application reduces the squeezing of the patient's injured part by using flexible materials for the airbag.

[0035] The nozzle 7 is connected to the electric telescopic tube 6 to achieve telescopic injection. Specifically, the storage bin 5 adopts a detachable medicine bottle and a pre-filled syringe design, so that the storage bin 5 is compatible with liquid, gel, foam and other dosage forms.

[0036] Furthermore, the electric telescopic tube 6 has a built-in hollow conduit, which can be extended and retracted along the axis. The electric telescopic tube 6 adopts a silicone bellows to maintain sealing when extending and retracting. Sealing rings are provided at the connections between the two ends of the electric telescopic tube 6 and the storage bin 5 and the nozzle 7.

[0037] Specifically, an air storage tank 8 is provided in a ring along the outer wall of the nursing tube 2, and an air pump is provided inside the air storage tank 8. The output end of the air pump is connected to the air bag 9 through the solenoid valve 10. The air bag 9 is arranged in a ring on the inner wall of the nursing tube 2. The solenoid valve 10 passes through the outer wall of the nursing tube 2 and extends to the inner cavity. The air bag 9 is detachably connected to an ice compress belt on the side away from the solenoid valve 10. The ice compress belt is provided with a pressure sensor, and the pressure sensor is electrically connected to the solenoid valve 10.

[0038] The present application arranges an ice compress belt on the airbag 9 and a pressure sensor on the ice compress bag 11, detects the pressure between the airbag 9 and the patient's body surface through the pressure sensor, and controls the inflation and deflation state of the airbag 9 through the solenoid valve 10, so as to adapt to the body diameters of different patients, avoid the airbag 9 from inflating too much and squeezing the patient's body surface, and avoid the airbag 9 from inflating too little and the ice compress bag 11 not contacting the patient's body surface.

[0039] The solenoid valve 10 controls the opening and closing of the valve by turning on and off the power. Specifically, the solenoid valve 10 includes three working modes, namely:

[0040] Inflation mode: Power on, air flows to the airbag 9;

[0041] Shut-off mode: shut down the power supply and block the airflow;

[0042] Exhaust mode (three-way valve): switch the airflow to atmospheric pressure relief, so that the airbag 9 returns to its initial state.

[0047] Example 2

[0048] Based on the above-mentioned embodiment 1, further, in this embodiment, a nozzle 7 anti-pollution cover is provided on the electric telescopic tube 6, which automatically covers the nozzle 7 when it is retracted. The nozzle 7 anti-pollution cover adopts a linked sliding cover design, that is, the electric telescopic tube 6 is extended to push the sliding cover to move sideways, and the nozzle 7 anti-pollution cover automatically opens. When the electric telescopic tube 6 is retracted, the nozzle 7 anti-pollution cover is automatically closed and sealed.

[0049] Furthermore, in this embodiment, a massage ball array is provided in an annular manner inside the nursing cylinder 2, wherein the massage ball array is connected to an external power source, that is, the orthopedic care of this application includes three stages, specifically:

[0050] Phase 1: Cold compress period, vasoconstriction (reduced bleeding / exudation), capillary permeability reduced by 40% through low temperature

[0051] Phase 2: Massage intervention phase, targeted pressure to promote venous return, driving tissue fluid return through 0.3-0.5 MPa periodic pressure;

[0052] Phase 3: Rewarming period, vasoactive dilation (metabolic waste removal), and the thermal effect of massage increases local blood flow rate by 200%.

[0053] Furthermore, in this embodiment, the nursing tube 2 adopts a telescopic design, which allows the application to adapt to the differences in leg length, hand length or other parts of different patients.

[0054] Furthermore, the electric telescopic tube 6 is internally integrated with an injection needle. The needle tip is exposed only after being extended, and is completely enclosed when retracted to prevent needlestick injuries. By adjusting the extension amount of the electric telescopic tube 6 and filling different medicines in the storage bin 5, orthopedic care in different scenarios can be adapted. Specific examples are as follows:

[0055] 1. Open wound debridement (such as infection after fracture surgery)

[0056] 1. Symptom characteristics: purulent secretions;

[0057] Spray drug regimen: povidone iodine + lysozyme nanospray;

[0058] Electric telescopic tube 6 telescopic range: 15-20mm;

[0059] Technical effect: Avoid contact with the wound surface and cause secondary damage, high-pressure pulse flushing (0.5MPa).

[0060] 2. Open wound debridement

[0061] Symptom characteristics: Necrotic tissue adhesion;

[0062] Spray drug regimen: collagenase spray;

[0063] Electric telescopic tube 6 telescopic range: 10-15mm;

[0064] Technical effect: Enzymatically dissolve necrotic tissue, and the telescopic nozzle penetrates deep into the cavity (avoiding blood vessels and nerves).

[0065] 2. Rehabilitation of joint stiffness (such as after knee replacement surgery)

[0066] 1. Symptom characteristics: joint adhesion;

[0067] Spray drug regimen: Hyaluronidase + sodium hyaluronate combined spray;

[0068] Nozzle expansion: 25-35mm;

[0069] Technical principle: The nozzle is inserted into the joint gap, and the atomized particle size is ≤20μm (to ensure coverage of the synovial membrane).

[0070] 2. Symptom characteristics: muscle spasms

[0071] Spray drug regimen: Botulinum toxin A sustained-release spray;

[0072] Nozzle expansion and contraction: 5-8mm;

[0073] Technical principle: close to the skin but not in contact (to prevent low temperature stimulation), ion introduction enhances penetration.

[0074] 3. Chronic inflammatory pain (such as tennis elbow, frozen shoulder)

[0075] 1. Symptom characteristics: local tenderness

[0076] Spray drug regimen: diclofenac liposome spray;

[0077] Nozzle expansion and contraction: 3-5mm;

[0078] Technical principle: Near-field cold mist spray (4°C) constricts blood vessels and reduces bleeding.

[0079] 2. Symptom characteristics: deep inflammation

[0081] Nozzle expansion: 20-25mm;

[0082] Technical principle: Penetrate the fascia layer under ultrasound guidance (medical imaging linkage positioning is required).

[0083] Furthermore, in this embodiment, the injection mechanism can adopt an integrated slit spray robot end effector to realize the spray function, and the specific core components include:

[0084] Telescopic mechanism: piezoelectric ceramic actuator (telescopic accuracy ±0.01mm) + carbon fiber guide rod;

[0085] Adaptive nozzle: six-axis force sensing joint (real-time adjustment of nozzle angle to fit the curved surface);

[0086] Anti-blocking design: built-in ultrasonic vibrator (frequency 40kHz), automatically retracts and oscillates when the machine stops.

[0087] Example 3

[0088] Based on the above-mentioned embodiment 1, a heating plate is embedded in the nursing tube 2. In orthopedic care, a device combining cold compress with heating can break through the limitation of single cold compress and improve the rehabilitation effect through alternating cold and hot or synergistic effects.

[0089] Prolonged cold compresses can easily lead to tissue frostbite and excessive vascular contraction (risk of ischemia). By setting periodic low-temperature cold compresses (such as 15 minutes) and short-term hyperthermia (5 minutes, 38-40°C), capillary vasodilation can be promoted, blood perfusion can be maintained, and the risk of tissue necrosis can be reduced.

[0090] Furthermore, through the mechanism of alternating hot and cold, cold compress can constrict blood vessels to reduce exudation, while hot compress can dilate blood vessels to increase blood flow. The alternating hot and cold group reduced swelling 42% faster than the simple cold compress group, and the lactic acid clearance efficiency increased by 35%, which accelerated the clearance of metabolic waste.

[0091] Furthermore, cold compresses inhibit the excitability of muscle spindles to achieve pain relief, while hot compresses reduce the activity of motor neurons to achieve spasm relief. To relieve muscle spasms and stiffness.

[0092] Furthermore, cold compress can densify the epidermis, and heat therapy at 38°C immediately after cold compress can open the pores and intercellular spaces, thereby synergistically promoting drug penetration.

[0093] In some other embodiments, devices providing heat therapy include, but are not limited to, electric heating plates, such as PTC ceramic heating films, circulating water heating, and phase change material heat storage sheets.

[0094] Example 4

[0095] In this embodiment, a sensor module and a camera module are integrated inside the nursing tube 2, specifically including:

[0096] A temperature sensor array is provided along the inner wall of the nursing tube 2 to prevent the temperature inside the nursing tube 2 from being excessive during the ice application process, thereby preventing frostbite on the patient's body surface and causing secondary injury;

[0097] The time relay is provided in the circuit of the solenoid valve 10. When the inflation time of the airbag 9 reaches a preset value, the air is deflated through the solenoid valve 10, causing the airbag 9 to shrink, thus preventing frostbite caused by long-term ice compress.

[0098] Piezoelectric bone conduction sensors and micro strain gauges can quantify the mechanical strength of the callus by detecting the hardness and microstrain distribution of the callus, and predict the healing time;

[0099] The nine-axis IMU and angle encoder dynamically assess the level of functional recovery and provide early warning of joint stiffness by detecting joint range of motion (ROM) and gait symmetry;

[0100] Ultrasonic elastography sensors detect tendon elastic modulus and fiber continuity to identify scar adhesions and guide rehabilitation intensity;

[0101] Infrared thermal imaging camera, by detecting the degree of tissue edema and local temperature field, quantitatively classifies inflammation and optimizes anti-inflammatory plans;

[0102] Surface electromyography and piezoresistive tactile sensors evaluate nerve innervation recovery and prevent muscle atrophy by detecting electromyographic signals and tactile feedback intensity.

[0103] Specifically,

[0104] When the condition is a distal radius fracture, bone conduction sensor detection can shorten bone healing time and reduce the incidence of joint stiffness.

[0105] When the condition is Achilles tendon rupture repair, ultrasound elastography and sEMG can reduce postoperative recovery time;

[0106] When the condition is lumbar fusion, the six-dimensional force sensor + BIS can reduce low back pain and the rate of adjacent segment degeneration.

[0107] Example 5

[0108] Based on the above embodiments, the working principle of this application can be derived, specifically:

[0109] Before care: When orthopedic care is required for a patient, the patient inserts the body part to be cared for into the inner cavity of the care cylinder 2, and the storage bin 5 is filled with appropriate medicine according to the actual care needs;

[0110] In the initial state, the electric telescopic tube 6 is in a contracted state, driving the nozzle 7 to move. That is, at this time, the nozzle 7 is not located in the inner cavity of the nursing tube 2, avoiding affecting the patient's body surface to enter the interior of the nursing tube 2.

[0111] During nursing care: After the device is placed stably, the air pump inside the air storage tank 8 is started, and the air pump drives the air bag 9 connected thereto to inflate, and the air bag 9 drives the ice pack to contact the patient's body surface. The pressure sensor provided on the surface of the air bag 9 detects the pressure between the air bag 9 and the patient's body surface. When the pressure is too high, the solenoid valve 10 is closed to prevent the air bag 9 from inflating too much and causing secondary damage to the patient;

[0112] During the ice compress process, when the ice compress position is changed according to nursing needs, the airbag 9 is deflated by the solenoid valve 10, so that the airbag 9 is moved away from the patient's body surface;

[0113] After the ice pack 11 is away from the patient's body surface, the motor is started, and the transmission gear 4 and the rack 3 are meshed to make the nursing tube 2 slide on the support block 16 and the connecting block 13 to adjust the position of the ice pack;

[0114] According to actual needs, repeat the above operation of starting the air pump inside the air storage tank 8 to perform a second ice compress;

[0115] According to the nursing needs, that is, when spraying medicine is needed, after the ice pack 11 is away from the patient's body surface, the electric telescopic tube 6 is started. At this time, the electric telescopic tube 6 is in an extended state, driving the nozzle 7 to move. That is, at this time, the nozzle 7 is located in the inner cavity of the nursing tube 2. The medicine inside the storage bin 5 is compressed by the nozzle 7, so that the medicine is sprayed out through the electric telescopic tube 6 in a spray manner, thereby improving the orthopedic nursing effect;

[0116] Furthermore, according to nursing needs, that is, when heat therapy is needed, after cold compress, the electric heating plate embedded in the nursing cylinder 2 is started to enhance the rehabilitation effect through alternating cold and hot or synergistic effects.

[0117] When the nursing seat 1 needs to be hung, such as when performing calf orthopedic care, the elastic bands 15 of the side grooves 14 are pulled out, and any two elastic bands 15 are connected by buckles, and the nursing seat 1 is hung by the connected elastic bands 15.

[0118] After care: the storage bin 5 can be replaced by the detachable connection between the spraying mechanism and the outer wall of the care tube 2, and the ice compress belt can be replaced by the detachable connection between the ice compress belt and the air bag 9, so as to avoid cross infection caused by reuse.

[0119] The above embodiments are merely descriptions of preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
