Description

TECHNICAL FIELD

[0001] The present application relates to the field of orthopedic nursing equipment, in particular to an adjustable cold compress device for orthopedic nurses. BACKGROUND

[0002] In the field of orthopedic clinical nursing, cold compress as a core intervention means in the early rehabilitation stage after traumatic surgery plays an irreplaceable role in relieving local swelling, inhibiting inflammatory reaction and reducing pain of the affected limb after surgeries such as fracture and joint replacement. Its application can directly affect the postoperative rehabilitation process and comfort of patients, so it occupies an important position in postoperative nursing of orthopedics.

[0003] At present, the cold compress device for orthopedic nursing widely used in clinical practice is usually designed with a simplified structure, mainly composed of a functional carrier for containing a refrigerant (such as solid ice bag, gel-like condensate, etc.). According to the requirements of the use scene, the functional carrier is designed as a flexible bag body or a rigid shell structure. By directly adhering to the skin of the affected part of the affected limb, the phase change heat absorption or heat conduction characteristics of the refrigerant are used to achieve local cooling, thereby achieving the cold compress nursing effect. To avoid displacement of the device during cold compress and ensure stable cooling effect, some existing devices are equipped with elastic bands, magic tapes and other fixing components. The device is fixed to the corresponding part of the affected limb by binding or pasting, so as to maintain the adhesion state of the device and the affected part.

[0004] However, in the actual clinical application process, the above-mentioned existing cold compress device still has obvious technical limitations, which is difficult to adapt to the special nursing needs of the affected limb after orthopedic surgery. The specific technical problems are as follows: Unable to handle the exudate of the affected limb, interfering with the healing process of the affected part: In the early stage after orthopedic traumatic surgery, the affected part of the affected limb often has physiological exudate (such as tissue fluid, a small amount of blood exudate, etc.) due to tissue damage. The bag body or shell of the existing cold compress device is usually a non-absorbing structure, and no exudate absorption module is integrated, so the exudate is easy to accumulate between the contact interface of the device and the skin of the affected part. On the one hand, this accumulation can destroy the microenvironment stability required for healing (such as breaking the local humidity balance and hindering the gas exchange required for tissue repair), and on the other hand, it may cause local skin irritation due to long-term retention of exudate, even increasing the risk of secondary infection, directly interfering with the normal healing process of the affected part.

[0005] Leakage of exudate is easy to occur, and the nursing environment is polluted: the fixing components (elastic bandage, magic tape) of the existing device can only realize the relative fixation of the device and the affected limb, and cannot effectively seal or guide the accumulated exudate; when the amount of exudate exceeds the accommodation limit of the contact interface, it is easy to overflow from the edge of the device (such as the joint of the bag body, the gap between the shell and the skin), and then pollute the bedclothes, clothes and other nursing supplies of the patient, which not only increases the cleaning and maintenance workload of medical staff, but also may damage the health safety of the nursing environment, and there is a potential risk of cross infection.

DETAILED DESCRIPTION

[0021] In order to further understand the content of the present application, the present application will be described in detail in conjunction with the drawings and examples. It should be understood that the examples are only to explain the present application and not to limit it.

[0022] Example 1, in conjunction Figures 1 to 5 with the drawings, the present embodiment provides an adjustable cold compress device for orthopedic nurses, which aims to solve the problems of existing devices such as lack of liquid treatment capacity, poor fit, and non-adjustable cold compress range. The adjustable cold compress device for orthopedic nurses includes a cold compress device body 100, which is a whole functional carrier, and the core component is a rubber sheet 110 made of medical grade silicone rubber material, which has good flexibility, biocompatibility and thermal conductivity, and can closely fit the curved surface of the affected limb (such as arm, leg, knee joint, ankle joint, etc.), avoiding the problem of uneven cooling caused by too large gap between the existing rigid shell and the skin. The water flow channel 210 is integrally formed inside the rubber sheet 110. The water flow channel 210 is the core path for condensate flow and heat exchange, designed as a serpentine structure composed of U-shaped detour sections 240 (the specific number is adapted according to the length of the rubber sheet 110).

[0023] The main water inlet 220 and the main water outlet 230 are arranged at both ends of the rubber sheet 110 along the length direction and are in communication with the head end and the tail end of the water flow channel 210; they are used for quick docking with the pipe of an external condensate water supply device (such as a medical cold water machine) to form a closed loop circulation. The side walls of the rubber sheet 110 are uniformly distributed with side water inlets 1110 along the length direction, and each U-shaped detour section 240 corresponds to one side water inlet 1110, and the side water inlet 1110 is in communication with the middle part of the curved section of the U-shaped detour section 240; the specifications (interface type, outer diameter, sealing method) of the side water inlet 1110 are completely consistent with those of the main water inlet 220, and the side water inlet 1110 can be used as a "segmented inlet and outlet" (such as a segmented water outlet when local cold compress is performed); when not in use, the side water inlet 1110 is blocked by a threaded sealing plug 1120, and the sealing reliability after being screwed is consistent with that of the main interface.

[0024] An occlusion through hole 1130 is arranged on one end surface (a non-skin contact surface) of the rubber sheet 110 along the length direction, each middle section of the U-shaped detour section 240 corresponds to one occlusion through hole 1130, the occlusion through hole 1130 is in communication with the inside of the water flow channel 210, and a built-in rubber sealing plug 1140 is arranged in the occlusion through hole 1130; when the rubber sealing plug 1140 is inserted, the water flow channel 210 corresponding section is completely blocked; when the rubber sealing plug 1140 is pulled out, the water flow channel 210 corresponding section is restored to be in communication, and the quick switching of "full section and segmented cold compress" is realized.

[0025] The connecting mechanism is used for connecting and fixing both ends of the rubber sheet 110, and is suitable for limbs of different thicknesses, and specifically includes a U-shaped frame 130, a fixed bolt 330, a half-dental bolt 150, a fixed nut 180 and a matching structure; the U-shaped frame 130 is made of light aluminum alloy material, the opening width of the U-shaped frame 130 is consistent with the width of the rubber sheet 110, and U-shaped frame through holes 320 are arranged on both side walls of the U-shaped frame 130.

[0026] One end of the rubber sheet 110 (near the main water outlet 230 side) is embedded with a metal insert, and a threaded blind hole 310 is formed on the insert; a fixing bolt 330 is inserted through a U-shaped bracket through hole 320 and is screwed with the threaded blind hole 310, thereby hinging the U-shaped bracket 130 to the end of the rubber sheet 110. The U-shaped bracket 130 can rotate around the axis of the fixing bolt 330 to adapt to the bending angle of the affected limb. A strip-shaped through hole 140 is formed on the middle beam of the U-shaped bracket 130, and a half-dental bolt 150 can freely slide and rotate in the strip-shaped through hole 140. The two ends of the rubber sheet 110 along the width direction are integrally formed with tooth grooves 160, and the tooth grooves 160 extend along the length direction of the rubber sheet 110. A tooth block 170 is fixedly sleeved on the non-threaded section of the half-dental bolt 150, and the tooth shape, tooth pitch and tooth groove 160 of the tooth block 170 are completely matched to achieve meshing and locking. A fixing nut 180 is sleeved on the threaded section (the part protruding out of the strip-shaped through hole 140) of the half-dental bolt 150; during adjustment, the half-dental bolt 150 is pushed to move along the strip-shaped through hole 140 to change the wrapping circumference of the rubber sheet 110 (to adapt to the thickness of the affected limb), the half-dental bolt 150 is rotated to make the tooth block 170 mesh with the tooth groove 160 (to prevent loosening), and finally the fixing nut 180 is tightened to achieve firm fixation of the device.

[0027] The fixing mechanism is used for fixing the medical absorbent cotton sheet (liquid absorption carrier) and forming a closed space to prevent leakage of the exudate. The fixing mechanism specifically comprises a sealing cover 190, a connecting column 520, a connecting bolt 570 and a matching structure. A plurality of drainage through holes 120 are uniformly formed on the rubber sheet 110 along the length and width directions, the drainage through holes 120 penetrate through the rubber sheet 110, and the inner walls of the openings at the two ends of the drainage through holes 120 are outwardly expanded to form mounting steps 510, which provide positioning support for the connecting column 520.

[0028] The connecting column 520 is made of medical ABS material and has a cylindrical shape, one end of the connecting column 520 is outwardly expanded to form a connecting leg 530, and the other end of the connecting column 520 is provided with a connecting column threaded hole 540; after the connecting column 520 is inserted into the drainage through hole 120, the connecting leg 530 is clamped with the mounting step 510 to achieve axial positioning of the connecting column 520. The sealing cover 190 and the connecting seat 550: the sealing cover 190 is made of transparent medical PC material (convenient for observing the exudate of the cotton sheet), the connecting seat 550 is integrally formed at a corner of the sealing cover 190, and the connecting seat 550 is provided with a connecting seat through hole 560.

[0029] The connecting bolt 570 is inserted through the connecting seat through hole 560 and is screwed with the connecting column threaded hole 540 to fix the sealing cover 190 to the non-skin side of the rubber sheet 110; at this time, the sealing cover 190 and the rubber sheet 110 form a placing cavity 410 for accommodating the medical absorbent cotton sheet, the cotton sheet covers the drainage through hole 120, and the drainage through hole 120 can absorb the tissue fluid or blood exudate of the affected limb.

[0030] The sealing cover 190 is integrally formed with a connecting pipe 1100, the connecting pipe 1100 is made of medical PVC and communicates with the inside of the placement cavity 410; the connecting pipe 1100 can be connected with an external air heating device (such as a medical air heater, the air outlet temperature is 38-40 DEG C) through a medical catheter, and warm air is sent into the placement cavity 410, so that the alternating nursing of "early postoperative cold compress (anti-inflammatory and swelling)" and "later hot compress (promoting blood circulation)" is realized, without the need to replace the device, and the nursing efficiency is improved.

[0031] The cold compress cooling principle is realized by "condensate water circulation heat exchange": after the external condensate water enters the water flow channel 210, heat exchange with the rubber sheet 110 occurs, and the heat absorbed by the rubber sheet 110 from the affected limb is absorbed; the serpentine U-shaped detour section 240 increases the heat exchange area and time, ensures that the temperature of the rubber sheet 110 is uniformly reduced, and then the cooling effect is transmitted through the adhesion of the rubber sheet 110 and the skin, and the inflammation and swelling of the affected limb are inhibited.

[0032] The exudate treatment principle forms a closed loop through "liquid guiding, absorbing and sealing": the exudate of the affected limb is guided out through the drainage through hole 120 to the cotton sheet in the placement cavity 410, and the cotton sheet actively absorbs the exudate through capillary action; the sealing cover 190 and the rubber sheet 110 are closed to prevent exudate leakage and maintain the cotton sheet in a moderate state of wetness (to avoid exudate accumulation or excessive drying), thereby ensuring the healing microenvironment of the affected area.

[0033] The flexible fixing principle is realized by "hinged and tooth groove engagement" to adapt: the hinged structure of the U-shaped bracket 130 and the rubber sheet 110 can adapt to the profile of the affected limb, the movement of the half-dental bolt 150 in the strip-shaped through hole 140 can adjust the wrapping tightness, the engagement of the tooth block 170 and the tooth groove 160 fixes the locking of the nut 180, and the device is not displaced when the affected limb moves.

[0034] The range adjustment principle controls the water flow path through "cutting and segmented inlet and outlet": the rubber sealing plug 1140 inserted into the blocking through hole 1130 can cut off the water flow, and the side water inlet 1110 serves as a segmented inlet and outlet, and the two can change the flow range of the condensate water in the water flow channel 210, realizing the switching between full-section cold compress and segmented cold compress.

[0035] The adjustable cold compress device for orthopedic nurses in the embodiment can achieve the following effects through the above-mentioned solutions: 1. The existing device does not have an exudate absorption module, and the exudate is retained between the device and the skin, forming a "wet environment", which causes the skin to be soaked, secondary infection, and delays the healing process. The adjustable cold compress device for orthopedic nurses in the embodiment can quickly guide the exudate out through the drainage through hole 120, the cotton sheet actively absorbs, and the closed environment formed by the sealing cover 190 reduces the contact of external bacteria, combined with the adsorption of the cotton sheet, which preferably reduces the risk of infection.

[0036] 2. Existing devices rely solely on elastic straps or Velcro for fixation, lacking a sealing structure. Leakage easily overflows from the edges, staining bedding and clothing. In this embodiment, the adjustable cold compress device for orthopedic nurses, through the combined use of a sealing cap 190 and a rubber sheet 110, allows for the absorption of leakage through cotton pads, effectively preventing leakage. Even when the cotton pads are saturated, the sealing cap 190 can temporarily store the leakage, which can be disposed of when the cotton pads are replaced.

[0037] 3. The flexibility of the rubber sheet 110 and the adjustability of the connecting mechanism can be adapted to different parts such as the upper limbs, lower limbs, and joints, as well as the limb size of patients of different ages and body types, thereby better improving the applicability of the adjustable cold compress device for orthopedic nurses in this embodiment.

[0038] 4. In this embodiment, the connecting tube 1100 can introduce hot air to achieve alternating care of "early cold compress to reduce swelling and later hot compress to promote blood circulation", thereby improving the care effect on the affected area.

[0039] 5. Segmented cold compresses can precisely avoid wound sutures and areas with reduced sensation, preventing frostbite and improving the safety of care.

[0040] Example 2, combined with Figure 6 as well as Figure 7 As shown, this embodiment is based on the device structure of Embodiment 1, and designs two typical working conditions to meet different cold compress range requirements (the arrows in the figure indicate the direction of water flow). The details are as follows: Condition 1: Apply cold compress evenly to the entire limb (suitable for cooling the entire limb, such as applying cold compress to the entire lower leg after tibial fracture surgery). The main inlet 220 and main outlet 230 are open, while all side inlets 1110 (sealed by threaded sealing plugs 1120) and all sealed through holes 1130 (by removing the rubber sealing plugs 1140, allowing the water flow channel 210 to be fully open) are closed. External condensate flows through the main inlet 220, water flow channel 210, all U-shaped bends 240 (without interruption), main outlet 230, and external recovery device, ultimately achieving uniform cooling of the entire affected limb covered by the rubber sheet 110.

[0041] Operating Condition 2: Taking the intermediate condensation section as the 2nd-4th U-shaped bend section 240 as an example, the operation and process are explained in detail: Cotton pad installation: Loosen the connecting bolt 570, remove the sealing cap 190, and lay the medical degreased cotton pad flat on the non-skin-adhering side of the rubber pad 110 (focusing on covering the drainage holes 120 corresponding to the 2nd-4th U-shaped bends 240). Replace the sealing cap 190 and tighten the connecting bolt 570 (ensure the sealing strip is compressed and there are no gaps for leakage).

[0042] Condensate water equipment connection: connect the outlet pipe of the medical cold water machine with the corresponding side inlet 1110 of the second U-shaped bypass section 240, and connect the return pipe with the corresponding side inlet 1110 of the fourth U-shaped bypass section 240. Open the corresponding side inlet 1110 of the second U-shaped bypass section 240 (screw off the threaded sealing plug 1120, connect the outlet pipe of the cold water machine), and open the corresponding side inlet 1110 of the fourth U-shaped bypass section 240 (screw off the threaded sealing plug 1120, connect the return pipe of the cold water machine).

[0043] Pull out the rubber sealing plug 1140 of the blocking through hole 1130 corresponding to the first to fourth U-shaped bypass sections 240 to ensure that the tail end of the first U-shaped bypass section 240 is in communication with the head end of the second U-shaped bypass section 240, and the interiors of the second to fourth U-shaped bypass sections 240 are in communication. The main inlet 220, the main outlet 230, and the other side inlets 1110 are all in a closed state.

[0044] Insert the rubber sealing plug 1140 into the blocking through hole 1130 between the first and second U-shaped bypass sections 240 to cut off the communication between the first and second U-shaped bypass sections 240, and insert the rubber sealing plug 1140 into the blocking through hole 1130 between the fourth and fifth U-shaped bypass sections 240 to cut off the communication between the fourth and fifth U-shaped bypass sections 240, thereby ensuring that the condensate water only circulates in the second to fourth U-shaped bypass sections 240.

[0045] Flow path: medical cold water machine → 5°C condensate water → side inlet 1110 corresponding to the second U-shaped bypass section 240 → into the water flow channel 210 → flow through the second U-shaped bypass section 240 (bent section) in turn → third U-shaped bypass section 240 (full section) → fourth U-shaped bypass section 240 (bent section) → side inlet 1110 corresponding to the fourth U-shaped bypass section 240 → cold water machine return pipe → cold water machine (used after cooling).

[0046] In the working condition 1 of the present embodiment, by opening all the U-shaped bypass sections 240 (pulling out all the rubber sealing plugs 1140) and blocking all the side inlets 1110, the condensate water can cover all the water flow channels 210 in the rubber sheet 110, achieving uniform cooling of the entire affected limb and quickly relieving postoperative swelling and pain of the entire limb. In the working condition 2 of the present embodiment, by inserting the blocking through hole 1130 to cut off the water flow of the non-middle section and using the side inlet 1110 of the middle section to guide the flow, the condensate water only circulates in the target middle region (such as the second to fourth U-shaped bypass sections), and the temperature of this region is stabilized in a suitable range (precisely matching the local lesion cooling demand); there is no condensate water flowing through the non-middle region, and the temperature is close to the skin temperature of the affected limb, avoiding unnecessary cooling leading to skin discomfort or frostbite.

[0047] In summary, the above is only the preferred embodiment of the present application, any equivalent changes and modifications made in accordance with the scope of the present application patent application should be covered by the present application patent.
