Description

Technical Field

[0001] The present invention relates to the technical field of orthopedic ice cold application equipment, and specifically relates to an ice cold application device for emergency orthopedics.

Background Art

[0002] In the fields of emergency orthopedics and sports medicine, for patients with acute soft tissue injuries, joint sprains, fractures or after surgeries, timely and effective local ice cold application is the first choice of basic treatment means to suppress tissue swelling, relieve pain and reduce inflammatory reactions. An ideal cooling device should provide a stable low temperature, while achieving appropriate pressurization to enhance the treatment effect, and balance the comfort, operability and clinical hygiene safety of patients.

[0003] Currently, commonly used ice patch methods in clinical practice have the following limitations: the temperature of simple ice packs or chemical ice patches is difficult to maintain, the pressure cannot be controlled, and the adhesion to the body surface is poor. Some circulating ice patch systems have improved temperature stability, but they have clear deficiencies in essential performance. For example, a Chinese patent (publication number: CN222676651U) discloses an ice patch device for emergency bone injuries, comprising a U-shaped support frame, a storage tank connected to the bottom of the support frame, a carrier plate, an ice patch mechanism, and a circulating assembly. The carrier plate is located at the bottom relative to the inner wall of the support frame, and the ice patch mechanism is located on the relative inner wall of the support frame, positioned above the carrier plate. The ice patch mechanism is symmetrically positioned and used to wrap around the limb and increase contact with the skin surface. The circulating assembly is located below the carrier plate and is used to supply circulating water to the ice patch mechanism to enhance the cooling effect on limb contact. While it offers a cooling effect compared to simple cooling bags, this device provides enveloping pressure based on the static pressure of the circulating water flow. Adjusting the pressure inevitably changes the hydrodynamic parameters, leading to uncontrollable fluctuations in heat transfer and temperature distribution, making independent and precise adjustment of the two crucial therapeutic parameters, pressure and temperature, impossible. Furthermore, its symmetrical U-shaped structure and rigid unit are poorly adapted to the complex anatomical forms of joints such as elbows, knees, and ankles, making it difficult to achieve uniform and tight enveloping. Pressure blind spots are likely to occur, or local compression may be too heavy, easily affecting patient tolerance and treatment compliance. In addition, the ice application mechanism of this device comes into direct contact with the skin. If the patient's skin is damaged, wounded, or has a postoperative wound, and the circulating channels and contact parts do not use disposable medical materials or if there is a lack of effective disinfection and isolation mechanisms, it can easily become a route for microbial growth, posing an infection risk and failing to meet the hospital infection control requirements of emergency departments and wards.

[0004] Therefore, in order to address the problems of the current technology's low pressure regulation effect and susceptibility to infection, there is a need to provide an ice-cooling patch device for emergency bone injuries. [Overview of the project] [Problems that the invention aims to solve]

[0035] Specifically, the air pad layer 520 includes multiple airbag modules arranged in an array, each airbag module communicating with the air supply pipe 600 via a solenoid valve 521.

[0036] Specifically, the airbag modules will be installed in a 3x5 grid.

[0037] To make it easier to understand, the housing 100 provides a first mounting chamber 110, a second mounting chamber 120, and a disinfection chamber 130 inside, with each of these being independently provided, making it easy to install different components. The top of the housing 100 is provided with a top cover 140 that communicates with the first mounting chamber 110, and the side wall is provided with a vent 150 that communicates with the second mounting chamber 120 and an opening / closing door 160 that communicates with the disinfection chamber 130. The water storage tank 200 is installed in the first mounting chamber 110 and positioned directly below the top cover 140, so that when in use, an ice pack that has been frozen in advance is placed in the water storage tank 200 through the top cover 140 to cool the water in the water storage tank 200. The circulation pump 300 is installed in the first mounting chamber 110 and communicates with the water storage tank 200 via a connecting pipe. By installing the air supply pump 400 in the second mounting chamber 120, the second mounting chamber 120 communicates with outside air through the vents 150, facilitating the operation of the air supply pump. By housing the adhesive section 500 in the disinfection chamber 130, the adhesive section 500 includes sequentially laminated and fixed backing layer 510, air pad layer 520, ice-cooled adhesive layer 530, connecting layer 540, and disposable replaceable protective sheet 550. The disposable replaceable protective sheet 550 prevents the patient from developing serious infections during use, while also providing pressure hemostasis for patients with skin injuries. The air pad layer 520 is connected to the air supply pump 400 via the air supply pipe 600, which allows the air supply pump 400 to fill the air pad layer 520 with air, thereby pressurizing the patient's ice-cooled adhesive area during use of the device, and the water inlet of the ice-cooled adhesive layer 530 is connected to the circulation pump 300 via the water inlet pipe 700. The water outlet is connected to the water storage tank 200 via the water outlet pipe 800, allowing ice water to circulate through the ice-cooled adhesive layer 530, providing a constant temperature ice-covered environment and ensuring the effectiveness of the ice-covered area. By installing fixing assemblies 900 on both side walls of the adhesive portion 500, the adhesive portion 500 can be detachably fixed to the patient's ice-covered area.The air pad layer 520 is equipped with multiple array-like airbag modules that are connected to the air supply pipe 600 via solenoid valves 521. By controlling the opening degree and switches of the solenoid valves 521, the pressurizing effect of each airbag module can be controlled, allowing for flexible pressure application according to the patient's condition, enabling response to different patient situations and achieving pressure control.

[0038] Based on the above, the present invention provides an ice-cooling patch device for emergency bone injuries that can pressurize the ice-cooling patch layer 530 with the air pad layer 520 during use, thereby enhancing the ice-cooling effect. It also allows for the opening and closing of different airbag modules to be controlled by a solenoid valve, enabling the pressurization effect to be controlled according to the patient's needs. Furthermore, by replacing the disposable, replaceable protective sheet 550 after use and placing it in the disinfection room 130, cross-infection can be avoided when the device is used between different patients.

[0039] As shown in Figure 5, in some embodiments of the present invention, the airbag module includes a plurality of airbag units 522 arranged in an array, with adjacent airbag units 522 communicating with each other via flexible tubes, and at least one airbag unit 522 of the airbag module is provided with an exhaust valve.

[0040] Specifically, each airbag module contains nine airbag units 522. The nine airbag units 522 are arranged in a 3x3 configuration. Adjacent airbag units 522 are connected via flexible silicone rubber tubes, ensuring pressure balance across all airbag units 522 in each airbag module.

[0041] As shown in Figure 6, in some embodiments of the present invention, the ice-cooling patch 530 includes a heat-insulating pad 531 and a meandering hose 532.

[0042] Specifically, the upper surface of the heat-insulating pad 531 is fixedly connected to the air pad layer 520. The heat-insulating pad 531 is a closed-pore foamed polyethylene (EPE) pad.

[0045] Specifically, because the cross-sections of the meandering hose 532, the inlet pipe 700, and the outlet pipe 800 are all rectangular, the cold welding contact area is increased, thereby enhancing the cold welding effect.

[0046] As shown in Figure 8, in some embodiments of the present invention, the central portions of the air supply pipe 600, the water inlet pipe 700, and the water outlet pipe 800 are integrally bonded together.

[0047] Specifically, the air supply pipe 600 is installed in the middle, and the water inlet pipe 700 and water outlet pipe 800 are located on either side of the air supply pipe 600.

[0048] By installing the inlet pipe 700 and the outlet pipe 800, the air in the inlet pipe 600 can be cooled, and it can be understood that the cooling effect will be further improved. On the other hand, the adhesive installation of the three components is convenient for their storage.

[0053] Specifically, the skin-touch layer 552 is fixedly installed on the underside of the waterproof layer 551. The skin-touch layer is made of medical-grade nonwoven fabric.

[0054] What is understandable is that after use, the disposable, replaceable protective sheet 550 can be replaced using double-sided tape, and for patients with damaged skin, the skin-touch layer ensures hygiene while also providing hemostatic effects. The waterproof layer 551 can prevent infection from blood penetration.

[0055] Referring to Figure 9, in some embodiments of the present application, the fixed assembly 900 includes a first band 910 and a second band 920.

[0056] Specifically, the first band 910 has one end fixed to one side wall of the adhesive portion 500, and the front surface of its free end is provided with a hook-and-loop fastener surface.
