Description

Technical Field

[0001] The present invention belongs to the technical field of cooling appliances for human body treatment, and in particular relates to a handheld physical cooling device for clinical use. Background Art

[0002] During clinical surgical treatment and nursing care, wounds are left behind, and the patient's body actively mobilizes immune cells to the wound to suppress infection. However, immune cells reside in the blood, so blood, which is slightly warmer than the body's surface temperature, concentrates in the wound, causing it to feel warm. In this case, physical cooling is generally used.

[0003] The most common method of physical cooling in clinical practice is to use an ordinary ice pack. However, ice packs cannot come into direct contact with the skin, so they must be wrapped with a towel. However, even with a towel, the ice pack will condense moisture from the air during use, forming water droplets that wet the towel and the wound, making it difficult to keep the wound dry. In severe cases, it can even affect wound healing, thus affecting the applicability of physical cooling.

[0004] Among the clinical physical cooling devices in the related art, there are disclosed hanging cooling devices such as CN215839861U, CN216570439U, CN215606789U, etc., and also disclosed binding cooling devices such as CN213821993U, CN216124651U, CN111904708B, etc. Although they all have a cooling effect, they do not solve the problem of moisture in the air condensing to form water droplets and wetting the wound during the ice compress process. Summary of the Invention

[0005] The present invention aims to provide a handheld physical cooling device for clinical use, so as to solve the problem that moisture in the air condenses to form water droplets and wets the wound during ice application.

[0006] In order to achieve the above-mentioned purpose, the solution of the present invention is: a handheld clinical physical cooling device, comprising a base body and a cover body, a limiting structure for limiting the separation of the cover body and the base body is provided between the cover body and the base body; a sink is provided on the side of the base body facing the cover body, a sponge block is provided in the sink, at least one strip groove is opened at the bottom of the sink, a water absorption roller is rotatably connected in the strip groove, the axis of the water absorption roller is parallel to the length direction of the strip groove, and the circumferential side of the water absorption roller is covered with a water absorption layer, which abuts against the sponge block; a bracket is installed on the side of the base body facing away from the sink, the bracket is rotatably connected to the cooling roller, the water absorption roller abuts against the cooling roller, the length of the cooling roller is not greater than the length of the water absorption roller, an accommodating cavity is provided in the cooling roller, a water leakage hole is opened on the side wall of the sink, an opening corresponding to the sink is opened on the cover body, and a handle made of elastic material is installed on the cover body, the length of the handle is greater than the length of the opening, and the two ends of the handle are respectively connected to the opposite sides of the opening.

[0007] The working principle and beneficial effects of this solution are as follows: the chamber is used to hold cooling media such as ice cubes, ice water, or frozen metal blocks for cooling. The length of the handle is greater than the length of the opening, so that when the handle is arched outward from the opening, it functions as a handle. For physical cooling, the user holds the handle, gently touches the cooling roller to the area to be cooled, and then pushes the cooling roller to rotate. The rotation of the cooling roller also drives the water absorption roller. Once water droplets condense on the cooling roller, they are absorbed by the water absorption layer on the absorption roller and transferred to the sponge block in the trough during the rotation of the absorption roller, thus keeping the cooling roller dry at all times. The amount of water absorbed by the sponge block can be observed through the opening. When sufficient water has been absorbed, the handle is pushed into the opening. When the handle is sunken into the trough, it squeezes the sponge block, squeezing water out of the sponge. The squeezed water leaks out through the drain hole in the side wall of the trough. The handle is then pulled up to restore its arched position outward from the opening for continued use.

[0008] This solution has a compact and light structure. During use, the user can operate it with one hand, and the surface of the cooling roller in contact with the patient is always kept dry, which effectively solves the problem of moisture in the air condensing into water droplets and wetting the wound during the ice compress process.

[0009] Optionally, the cover is rotatably connected to the base, and the sink is circular. With this solution, a cylindrical sponge block can be used to increase water absorption. When the cover rotates relative to the base, the recessed handle can rotate and press the sponge block, allowing the sponge block to absorb more water and squeeze it out through the handle, thereby extending the time of a single physical cooling session and avoiding frequent squeezing of water.

[0010] Optionally, the sponge block is provided with a plurality of water guide channels, which are parallel to the axial direction of the water absorbing roller, so as to facilitate guiding the water squeezed out of the sponge block to the water leakage holes on the side when squeezing water.

[0011] Optionally, a water storage chamber is provided on the side of the cover body facing the base body, the water storage chamber is connected to the water leakage hole, the water storage chamber is located outside the sink, and a drainage hole is opened in the water storage chamber, and a plug is provided in the drainage hole. The water that is squeezed out is temporarily stored in the water storage chamber, and the water can be poured out after squeezing out the water multiple times, thereby avoiding frequent pouring out.

[0012] Optionally, a force applying plate is provided on the side of the cover body facing away from the base body, and the force applying plate is perpendicular to the cover body, so that the cover body can be rotated relative to the base body by pushing the force applying plate.

[0013] Optionally, the water absorption roller is biased toward a side edge of one side of the strip groove, and the water absorption layer abuts against the side edge. During the rotation of the water absorption roller, the side edge can squeeze the water absorption layer, and the squeezed water is more easily absorbed by the sponge block, thereby making it easier to keep the water absorption layer dry, and further helping to keep the cooling roller dry.

[0014] Optionally, flexible belts are connected to the bases at both ends of the cooling roller respectively. When the entire cooling device needs to be fixed to the patient's body, the flexible belts can be used to bind and fix it.

[0015] Optionally, the cooling roller is divided into two hollow sections, which are connected by threads. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 3 This is a partial cross-sectional view of the water absorption roller of the handheld clinical physical cooling device in Example 2 of the present invention. DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] The symbols in the drawings of the specification include: base body 1, cover body 2, opening 3, sink 4, limit groove 5, hook 6, water storage chamber 7, leakage hole 8, drainage hole 9, plug 10, sponge block 11, water guide channel 12, strip groove 13, water absorption roller 14, water absorption layer 15, bracket 16, cooling roller 17, force plate 18, handle 19.

[0021] Example 1

[0022] This embodiment is basically as Figure 1 、 Figure 2 As shown: A handheld clinical physical cooling device includes a base 1 and a cover 2. A sink 4 is provided on the side of the base 1 facing the cover 2. The sink 4 is circular, with a leakage hole 8 on the side wall of the sink 4 and an annular limiting groove 5 on the outer wall of the sink 4. A hook 6 is integrally formed on the side of the cover 2 facing the base 1. The hook 6 is hooked on the limiting groove 5 and is slidably connected to the limiting groove 5, allowing the cover 2 to rotate relative to the base 1. An annular water storage chamber 7 is also provided on the side of the cover 2 facing the base 1. The water storage chamber 7 is connected to the leakage hole 8 and is located outside the sink 4. The water storage chamber 7 has a drainage hole 9, and a plug 10 is provided in the drainage hole 9.

[0023] A cylindrical sponge block 11 is placed within the trough 4. Several water channels 12 are radially arranged within the sponge block 11. These channels 12 are formed by hollowing out the sponge from the sponge block 11. Two rectangular strip grooves 13 are formed at the bottom of the trough 4. The two strip grooves 13 have parallel long sides and are each integrally formed with an ear seat at each end. A water-absorbing roller 14 is positioned within the strip groove 13. The two ends of the water-absorbing roller 14 are rotatably connected to the ear seat. The axis of the water-absorbing roller 14 is parallel to the length of the strip groove 13. The circumferential side of the water-absorbing roller 14 is coated with a water-absorbing layer 15. In this embodiment, the water-absorbing layer 15 is also made of sponge and abuts against the sponge block 11.

[0024] Two brackets 16 are inserted into the side of the base 1 facing away from the trough 4. Brackets 16 are made of elastic hard rubber and have an interference fit with the base 1. A cooling roller 17 is rotatably connected to the end of bracket 16, facing away from the base 1, via a bearing. The cooling roller 17 consists of two hollow sections, one open at one end and the other sealed at the other. The open end is provided with internal and external threads, respectively. After inserting a cylindrical ice cube into one section of the cooling roller 17, the two sections are screwed together to form a joint. The suction roller 14 abuts against the cooling roller 17, and its length is equal to that of the suction roller 14. The lid 2 has an opening 3 corresponding to the trough 4. A handle 19 made of spring steel is mounted on the lid 2. The handle 19 is longer than the diameter of the opening 3 and hinged at its ends to opposite sides of the opening 3, with the axis of the handle 19 aligned with the diameter of the opening 3.

[0025] Two force applying plates 18 are provided on the side of the cover body 2 facing away from the base body 1 . The force applying plates 18 are perpendicular to the cover body 2 and are respectively located on both sides of the handle 19 .

[0026] The specific implementation process is:

[0027] For physical cooling, unscrew the two sections of cooling roller 17 (the ends of the two brackets 16 are spread apart), place ice cubes in, and then screw the two sections of cooling roller 17 back on. Pull handle 19 so that it arches outward from opening 3, gently touch the cooling roller 17 to the area to be cooled, and push cooling roller 17 to rotate. Cooling roller 17 drives water absorption roller 14 to rotate. Once water droplets condense on cooling roller 17, they are absorbed by the sponge on water absorption roller 14 and transferred to sponge block 11 in sink 4 during the rotation of water absorption roller 14, thus keeping cooling roller 17 dry at all times. Moreover, due to the arrangement of two water absorption rollers 14, one water absorption roller 14 absorbs water from cooling roller 17 once, and the other water absorption roller 14 absorbs water from cooling roller 17 twice, which effectively keeps cooling roller 17 dry. This effect is also effective regardless of whether cooling roller 17 rotates forward or reverse.

[0028] Observe the amount of water absorbed by the sponge block 11 through the opening 3. When the amount of water absorbed is large enough, push the handle 19 to recess into the opening 3. After the handle 19 is recessed into the sink 4, squeeze the sponge block 11 and stand the entire physical cooling device upright. Use your fingers to push and pull the two force plates 18 on the cover body 2 respectively. The cover body 2 rotates (or the cover body 2 is rotated by holding the handle 19). The recessed handle 19 rotates and crushes the sponge block 11, squeezing out the water in the sponge block 11. The water in the sponge block 11 flows into the water guide channel 12 first, and under the guidance of the water guide channel 12, flows to the circumferential edge of the sponge block 11, then flows out of the sponge block 11 and flows into the water storage chamber 7 through the leak hole 8. Pick up the handle 19 and use it again for physical cooling. After the water storage chamber 7 has stored a certain amount of water, pull out the plug 10 in the drain hole 9 and pour out the water.

[0029] Example 2

[0030] The difference between this embodiment and the first embodiment is that the two water-absorbing rollers 14 are biased toward the side of the outer side of the strip groove 13 and the water-absorbing layer 15 is against the side. Figure 3 The base bodies 1 at both ends of the cooling roller 17 are respectively connected with braided belts, and buckles are sewn on the free ends of the braided belts.

[0031] When the water-absorbing roller 14 rotates, the side edges that abut the strip grooves 13 squeeze the water-absorbing layer 15 on the water-absorbing roller 14. The squeezed water is more easily absorbed by the sponge block 11, thereby helping to keep the water-absorbing layer 15 dry and, in turn, the cooling roller 17 dry. The braided belt and buckle can be used to tie the entire physical cooling device to the patient's limb.
