Description

Technical Field

[0001] The present invention relates to the technical field of medical ice compress, and particularly to a conformable ice compress device. Background Art

[0002] Ice compress is a method of treating diseases by applying an ice pack or a mixture of ice water and medicine to the affected area. Through ice compress, pain relief, swelling prevention and inflammation reduction can be achieved on the affected area. By reducing the nerve conduction speed at low temperature, the pain tolerance is improved for local pain relief. The vascular permeability is reduced, and local exudate is decreased, so that the swelling symptoms are alleviated. Local cooling can inhibit the local body's own metabolic level and reduce the inflammatory reaction.

[0003] In the prior art, the commonly used ice compress method is to seal ice cubes or a mixture of ice water in a plastic bag to form an ice pack for ice compress on the affected area. Since the ice cubes have a large volume, large surface stiffness, edges and corners, they cannot fully contact the affected area, resulting in the area where the affected area contacts the ice cubes being too cold, while the areas without contact cannot achieve the purpose of cooling, leading to an unsatisfactory ice compress effect on the affected area. In order to make the ice compress uniform, it is necessary to move the ice compress bag back and forth on the affected area to ensure that all parts of the affected area can be ice compressed. This process not only increases the operation burden, but also if the operation is improper, the ice compress bag is likely to rub the affected area, resulting in possible secondary damage to the relatively fragile skin surface of the affected area.

[0004] In addition, due to the low temperature inside the ice pack and the high temperature outside the ice pack, the temperature difference causes water vapor in the external air to easily condense into water droplets on the surface of the ice pack. The water droplets carrying a large number of bacteria flowing to the affected area are likely to cause infection of the affected area. Summary of the Invention

[0005] Aiming at the above problems in the prior art, the present invention provides a conformable ice compress device, which solves the problems in the prior art that the ice pack does not contact the affected area evenly, resulting in frostbite or failure to achieve the cold compress purpose, and the condensed water droplets are likely to infect the affected area.

[0006] In order to achieve the above invention purpose, the technical solution adopted by the present invention is as follows:

[0007] There is provided a conformable ice compress device, which includes a strap. A hollow part is provided in the middle of the strap. A disinfected gauze is detachably connected to the hollow part. A flexible ice pack is provided on the side of the disinfected gauze away from the strap. The ice pack is filled with gel beads. Both ends of the ice pack are supported on the strap. The ice pack abuts against the disinfected gauze and a plurality of air bags are provided at non-abutting positions. Each air bag is independently provided with an inflation and deflation valve. The ice pack is fixed inside a conical open mask. The conical open mask is fixed to the air outlet of a drying jet. An air passage for introducing the dry gas generated by the drying jet to the bottom surface of the ice pack is provided inside the conical open mask. A feed port is provided on the ice pack, and a tightening band is provided on the feed port.

[0008] The beneficial effects of the present invention are as follows: The entire ice compress device can be fixed on the human body through the straps. The material for cooling in the ice pack uses frozen gel beads. The gel beads are small beads with a smooth outer surface. When applying ice compress, the shape of the ice pack can be changed more flexibly, enabling the ice pack to come into fuller contact with the affected area. The feeding port on the ice pack is tightly sealed by a tightening strap. When the tightening strap is loosened, the gel beads can be replaced in a timely manner to ensure the low temperature of the gel beads and thus ensure the ice compress effect. The disinfected gauze is arranged between the affected area and the ice pack, which can not only protect the affected area from infection caused by contact with the ice pack, but also buffer the extrusion of the ice pack and relieve the excessive coldness of the ice pack, making the affected area more comfortable. The disinfected gauze is detachably connected to the strap and can be replaced regularly as needed, reducing the infection probability of the affected area.

[0009] A plurality of air bags are arranged at non-contact positions on the ice pack. Each air bag is controlled by an independent inflation and deflation valve. By inflating different air bags, different parts of the ice pack can be squeezed, making the ice pack come into closer contact with the affected area. By deflating different air bags, the extrusion of the ice pack on the affected area can be reduced and removed. Thus, it can be realized that the affected area can be alternately ice-compressed by sequentially controlling the inflation and deflation of each air bag, avoiding freezing the tissue by ice-compressing the same place for a long time, ensuring both the ice compress effect and improving the safety of ice compress.

[0010] The drying air jet dries the air and sprays it onto the bottom surface of the ice pack through the air duct on the conical open mask. The bottom surface of the ice pack abuts against the disinfected gauze, surrounding the entire bottom surface of the ice pack with dry air. Even if there is a temperature difference, water droplets will not condense, ensuring the dryness of the disinfected gauze, reducing the infection rate of the affected area during ice compress, and greatly improving the comfort and safety of the patient's use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following describes the specific embodiments of the present invention to facilitate those skilled in the art of the present technology to understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art of the present technology, as long as various changes are within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are within the scope of protection.

[0015] As Figure 1 shown, the conformable ice compress device includes a strap 1, and both ends of the strap 1 are connected by a Velcro 9. The Velcro 9 includes a hook piece and a fluff piece, and the length of the connection of the strap 1 can be adjusted by increasing the distribution length of the fluff piece along the length direction of the strap 1 to adapt to the connection of different parts of the human body, such as the knee or the arm.

[0016] A hollowed-out part 11 is provided in the middle of the strap 1, and a disinfected gauze 2 is detachably connected to the hollowed-out part 11. The disinfected gauze 2 needs to be replaced regularly to keep the contact with the affected area clean and hygienic. The disinfected gauze 2 is a medical gauze after disinfection and sterilization. Both ends of the disinfected gauze 2 are fixed to the strap 1 by a Velcro or an elastic band. After the middle part of the disinfected gauze 2 is squeezed by the ice pack 3, it can pass through the hollowed-out part 11 to contact the affected area, and the ice pack 3 is prevented from directly contacting the affected area through the disinfected gauze 2.

[0017] A plurality of elastic band buckles 12 are provided on the strap 1, and the plurality of elastic band buckles 12 are distributed on both sides of the disinfected gauze 2. The elastic band buckles 12 are rectangular elastic bands, and both ends of the elastic bands are sewn on the strap 1. The elastic band buckles 12 fix the corresponding structure on the bottom plate by elastic compression inserting the bottom plate. Applying an external force to pull the elastic band buckles 12 can easily take out the bottom plate from the elastic band buckles 12, and loosening can tighten it again. Using the elastic band buckles 12 to fix objects is convenient for disassembly and assembly, lighter, and lower in cost.

[0018] A flexible ice pack 3 is provided on the side of the disinfected gauze 2 away from the strap 1. The ice pack 3 is filled with gel beads. The gel beads are small spherical objects made of gel, with a smooth appearance, and can be repeatedly frozen and thawed, and can remain spherical after thawing. The material of the ice pack 3 is a flexible plastic bag. The outer surface of the left end is fixed on the inner surface of the conical open mask 5, and an opening is provided at the right end as a feed port 31 for replacing the gel beads, because the gel beads become hot after ice compressing for a period of time and need to be replaced with new frozen gel beads to continue ice compressing.

[0019] A gel layer is coated on the inner side of the feed port 31, and the outer side is wound and tightened with a tightening band 7 by setting a belt buckle. By tightening the tightening band 7 and tying it to tighten the feed port 31, the gel layers coated on the inner side are squeezed against each other to make the sealing better, preventing the gel beads from being squeezed out by the airbag 4, and at the same time improving the heat preservation performance in the ice pack 3.

[0020] The ice bag 3 is also connected with a tubular diversion cover 8 at the feeding port end through fixing means such as bonding. The end of the diversion cover 8 far from the feeding port is upturned in an arc shape. The diversion cover 8 is supported by a support rod, and the bottom end of the support rod is hinged to a bottom plate, and the bottom plate is fixed by an elastic band buckle 12.

[0021] The diversion cover 8 is a plastic pipe with a smooth outer surface and no edges. When the gel beads need to be replaced, the arm or leg with the fixing strap 1 tilts the diversion cover 8 downward to directly pour out the internal gel beads. When pouring new gel beads, there is no need to manually open the ice bag 3, and the gel beads can directly flow into the ice bag 3 through the diversion of the diversion cover 8, which greatly improves the convenience of operation.

[0022] The ice bag 3 abuts against the disinfected gauze 2, and a plurality of air bags 4 are arranged at the non-abutting positions. The air bags 4 are integrally formed in the interlayer of the bag body of the ice bag 3, and each air bag 4 is separated by a plastic cloth. The bottom surface of the ice bag 3 abuts against the disinfected gauze 2. The air bags 4 are mainly distributed on the top surface and the side surface of the ice bag 3. The air bags 4 on the top surface and the side surface are selectively inflated according to the actual position of the affected area. For example, if the affected area is on the knee, since the surface of the knee is arc-shaped, it is necessary to simultaneously activate the air bags 4 on the top surface and the side surface to squeeze the ice bag 3 to make the ice compress more sufficient. If the affected area is on a plane such as the back of the hand, only the air bags 4 on the top surface need to be inflated to ensure the sufficiency of the ice compress.

[0023] Each air bag 4 is connected to an air pump 42 through an independent air pipe 43, and an air charging and discharging valve 41 is arranged on each air pipe 43. The air pump 42 and the air charging and discharging valve 41 are connected to a controller. The controller is preferably a single-chip microcomputer chip of model stm32f103c8t6. The air charging and discharging valve 41 and the air pump 42 are controlled by the controller. The controller alternately charges and discharges the air bags according to a preset method to realize alternate ice compress at different positions of the affected area and avoid being frozen at the same position for a long time.

[0024] The left end of the ice bag 3 is fixed inside the conical open mask 5, and the outer surface of the ice bag 3 is fully bonded to the inner conical surface of the conical open mask 5. The conical open mask 5 is fixed on the air outlet of the drying jet 6. An air passage 51 for introducing the dry gas generated by the drying jet 6 to the bottom surface of the ice bag 3 is arranged inside the conical open mask 5. As Figure 2 shown, it should be avoided that the ice bag 3 enters the air passage 51 to cause blockage of the air passage 51. The width of the air passage 51 is greater than the contact surface width between the ice bag 3 and the disinfected gauze 2 to ensure that no water droplets will condense on the entire bottom surface of the ice bag 3.

[0025] The drying jet 6 includes a blower, a compressor and a heat exchanger disposed within a housing 61. The working principle of the drying jet 6 is the same as that of a condensing dehumidifier. In both cases, air is sent in and out by the blower, and the compressor drives the heat exchanger to condense the moisture in the air, which is then discharged through a water discharge pipe 62. A water collection tray is provided below the heat exchanger, and the collected water is discharged through the water discharge pipe 62. By extending the water discharge pipe 62, water is prevented from being discharged onto the strap. The housing 61 is fixed to the top end of a support rod 63, and the bottom end of the support rod 63 is hinged to a support 64. The bottom of the support 64 is fixed with a bottom plate, and both ends of the bottom plate are inserted into two elastic belt buckles 12 for fixation.
