Description

Technical Field

[0001] The present invention relates to the field of traditional Chinese medicine medical technology, and in particular to a postoperative analgesia device and system based on traditional Chinese medicine nursing technology. Background Art

[0002] Postoperative pain management is one of the core aspects of surgical clinical care, especially excessive incision tension, local microcirculation disorders and accumulation of inflammatory mediators, which often lead to increased pain and delayed healing in patients.

[0003] In traditional postoperative pain management practices, medical professionals often view "Traditional Chinese Medicine hot compresses" and "external plasters" as complementary yet separate approaches. On the one hand, traditional Chinese medicine hot compresses, by warming the meridians and promoting blood circulation and removing blood stasis, can indeed improve local microcirculation around the incision, accelerate the dissipation of inflammatory mediators, and create favorable conditions for tissue repair. However, this therapy is essentially static warming: the medicine pack or bag is simply applied to the affected area, and its position and pressure remain relatively fixed, unable to dynamically adjust with changes in the patient's position or muscle contractions. If the patient turns over, coughs, or gets out of bed, the intense pain caused by the instantaneous traction on the incision is often not immediately relieved, and even delayed healing due to repeated tearing. Furthermore, to compensate for the lack of "rest," external plasters are often used to mechanically limit outward expansion of the wound. While the adhesive layer in a plaster can provide centripetal binding force for a short period of time, there's a natural conflict between its adhesion strength and skin tolerance: insufficient adhesion results in ineffective binding; excessive adhesion can easily cause epidermal avulsions when the plaster is removed during dressing changes or at the end of treatment, resulting in secondary pain and the potential for new wound infection. More critically, the plaster's inherent drug release capacity is limited by the colloidal matrix, making precise temperature-controlled release difficult. Consequently, efficacy and tension control remain two unrelated variables. Summary of the Invention

[0004] In response to the problems in the existing technology, the present invention provides a postoperative analgesia device and system based on traditional Chinese medicine nursing technology. The device tightens the affected area inward through two sets of baseboards, and the constant temperature heating structure on the baseboard can release the medicinal power evenly. At the same time, it has the advantages of traditional Chinese medicine hot compresses and plasters, which helps patients relieve pain and accelerate the healing of postoperative wounds.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In order to make this device have the advantages of traditional Chinese medicine hot compress and plaster at the same time, to help patients relieve pain better and accelerate the healing speed of postoperative wounds, on the one hand, Figure 1-8 As shown, the postoperative analgesia device and system based on traditional Chinese medicine nursing technology of the present invention includes: A vertical rod 1, wherein the vertical rod 1 is configured to rotate around its own axis; A base 2 is connected to the bottom rotating end of the vertical rod 1; Two sets of base plates 3 are hinged to the base 2 at a certain angle via a hinge shaft 4. A spiral spring 5 is provided on the hinge shaft 4 to provide an inward tightening force. Constant temperature electric heating blocks 6 are respectively arranged at the bottom of the two groups of substrates 2; A flexible substrate 7 is fixed to the bottom of the two sets of base plates 3 by screws and covers the constant temperature electric heating block 6; A silicone foam 8 is provided at the bottom of the flexible substrate 7 and has a concave-convex surface. A hollow cavity 9 is provided inside the silicone foam 8. The hollow cavity 9 is filled with Chinese medicine particles 10. The top and bottom of the silicone foam 8 are provided with drug penetration pores. The disposable contact body 11 is detachably connected to the bottom of the silicone foam 8 via medical adhesive.

[0021] During use, the vertical rod 1 and the base 2 rotate together, so that the two sets of base plates 3 can adjust the angle in real time as the body position changes; the spiral spring 5 provides a continuous and gentle inward tightening force, which can reduce the pulling pain caused by limb movement in the incision. The constant temperature electric heating block 6 transfers heat evenly to the silicone foam 8 under the cover of the flexible base 7, prompting the continuous release of the Chinese medicine particles 10 in the hollow cavity 9; the disposable contact body 11 isolates the wound surface, which not only keeps the medicine in contact with the skin, but also avoids cross contamination. This device tightens the affected area inward through the two sets of base plates 3, and the constant temperature heating structure on the base plate 3 can release the medicine power evenly. At the same time, it has the advantages of traditional Chinese medicine hot compresses and plasters, which helps patients relieve pain and accelerate the healing of postoperative wounds.

[0022] For example, Figure 1 As shown, the present invention also includes that a damping shaft 12 is provided at the upper end of the vertical rod body 1, and the top of the vertical rod body 1 is connected and fixed to the rotating end of the damping shaft 12 by a screw, and the damping shaft 12 is used to adjust the rotation resistance and maintain a specific angle.

[0023] When in use, the damping shaft 12 forms a controllable rotational resistance at the top of the vertical rod 1, so that the rod can stay stably at any angle; clinical staff or patients can fine-tune the direction of the device with one hand, reducing body discomfort caused by frequent movement.

[0024] For example, Figure 1 、 Figure 3 and Figure 7 As shown, the present invention also includes that the temperature control range of the constant temperature electric heating block 6 is 37°C to 45°C, and a thermostat 13 for adjusting the heating temperature of the constant temperature electric heating block 6 is provided on the top of the substrate 3, and the power input end of the thermostat 13 is electrically connected to the external power supply through a wire.

[0025] When in use, the temperature controller 13 is electrically connected to the constant temperature electric heating block 6, which can form a constant warm environment on the skin surface; the stable temperature range helps to reduce the repeated contraction and relaxation of local blood vessels caused by temperature fluctuations, thereby reducing the risk of pain sensitization.

[0026] For example, Figure 1 、 Figure 2 and Figure 3 As shown, the present invention also includes that the elastic coefficient of the spiral spring 5 is specifically set to generate a restoring force of 0.5-2N when the angle of the substrate changes by 10°.

[0027] When in use, the elastic coefficient is limited to the range of 0.5-2 N of restoring force for every 10° change in the angle, so that the base plate 3 can maintain moderate compression when the patient moves slightly; it avoids obstruction of blood flow due to excessive tightness and loss of support due to excessive looseness, thereby achieving dynamic balance incision protection.

[0028] For example, Figure 1 、 Figure 2 and Figure 5 As shown, the present invention also includes that the hollow cavity 9 of the silicone foam 8 is divided into a plurality of independent units, and each unit is filled with a combination of traditional Chinese medicine particles 10 of different particle sizes.

[0029] When in use, the hollow cavity 9 is divided into multiple independent units, which can be filled with Chinese medicine particles 10 of different sizes according to the length of the incision or the difference in the pain area; the drug distribution fits the contour of the wound better, reducing the waste of drug power.

[0030] For example, Figure 1 、 Figure 2 and Figure 5 As shown, the present invention also includes that the Chinese medicine granules 10 include a freeze-dried micro-powder mixture of Chuanxiong, Angelica, Frankincense, and Myrrh, with a particle size of 50-200 μm.

[0031] When in use, the four medicinal materials are freeze-dried and controlled to a particle size of 50-200 μm, which increases the specific surface area and allows for faster release of fat-soluble and water-soluble active ingredients under warm conditions.

[0032] For example, Figure 4 As shown, the present invention also includes that the flexible substrate 7 is made of medical-grade TPU material with a thickness of 0.5-2 mm, and a heat-conducting groove 14 matching the shape of the constant temperature electric heating block is provided on the surface.

[0033] When in use, the 0.5-2 mm thick TPU film has sufficient thermal conductivity while remaining soft and conformable; the thermal conductive groove 14 matches the shape of the constant temperature electric heating block 6, which can reduce the air gap at the heat conduction interface and reduce heat loss.

[0034] For example, Figure 1 and Figure 6 As shown, the present invention also includes that the disposable contact body 11 is configured as a two-layer structure of a medical non-woven fabric 15 and a PE composite film 16 , and the medical non-woven fabric 15 is located at the bottom of the PE composite film 16 .

[0035] When in use, the medical non-woven fabric 15 faces the skin, using its capillary pores to absorb exudate and maintain breathability; the PE composite film 16 faces away from the skin, forming a physical barrier to prevent the exudation of drug oil and external contamination; the two are hot-pressed and laminated together to form a light and thin overall structure, with low pulling force on the skin when torn off, reducing the pain of dressing changes.

[0036] For example, Figure 1 、 Figure 3 and Figure 7As shown, the present invention also includes a pressure sensor 17 provided on the inner side of the substrate, and an LED indicator 18 provided at one end of the top of the substrate 1 through a fixing groove, which is used to monitor the tightening force and provide real-time feedback through the LED indicator 18. The substrate 1 has a built-in battery for powering the pressure sensor 17 and the LED indicator 18.

[0037] During use, the pressure sensor 17 collects the pressure value of the substrate 3 on the incision in real time and feeds back the value in the form of colored light via the LED indicator light 18; medical staff can intuitively judge whether the current tightening force is within the safe range and make timely adjustments without the need for additional measuring tools, thereby improving nursing efficiency and patient safety.

[0038] On the other hand, a postoperative pain relief care system is used for the device as described above, such as Figure 8 As shown, the present invention also includes: Mobile terminal APP, used to receive data from the pressure sensor 17; The cloud database is used to store Chinese medicine formula parameters and user usage records for different wound types.

[0039] When in use, after the mobile terminal APP receives data from the pressure sensor 17, it can interact with the cloud database to archive the patient's incision tension, temperature and medication records; during subsequent follow-up or re-operation, historical parameters can be quickly called to form an individualized pain management file, reducing repeated evaluation time.

[0040] When the present invention is in use, the vertical rod 1 is fixed to the bedside bracket via the damping shaft 12, and is automatically locked after being rotated to a suitable angle to ensure that the entire device does not shake; lightly press the two sets of base plates 3, and the spiral spring 5 will generate a soft inward tightening force, which can effectively reduce the pain caused by the extension of the affected area; the pressure sensor 17 indicates whether the tightness is appropriate through the LED indicator 18 to avoid human estimation errors; turn on the thermostat 13, and the constant temperature electric heating block 6 is set at 37-45 ℃ stable heating; heat is evenly transferred through the heat-conducting grooves 14 of the flexible base 7, so that the Chinese medicine particles 10 in the silicone foam 8 continue to evaporate, and the medicinal power reaches the incision directly through the penetration pores; the medical non-woven fabric 15 of the disposable contact body 11 directly contacts the skin, which is moisture-absorbent and breathable; the PE composite film 16 is outward-proof and anti-bacterial; after 4-6 hours, the whole thing can be torn off and replaced with a new one without reheating; the APP automatically records the pressure and temperature data and uploads it to the cloud, and subsequent parameter adjustment does not require repeated measurements, shortening the nursing handover time; this application also has the advantages of traditional Chinese medicine hot compresses and plasters, which helps patients relieve pain and accelerate the healing of postoperative wounds.
