Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a medical ice blanket. Background Art

[0002] In clinical medicine, fever is one of the most common clinical manifestations of critically ill patients. Effective cooling measures are of great significance for controlling the condition and alleviating the pain of patients.

[0003] For febrile patients, traditional cooling methods include physical cooling and drug treatment. However, in cases of central hyperthermia caused by craniocerebral injury, due to the disorder of the body temperature regulation center function, simple drug treatment often has poor effects. Therefore, physical cooling is particularly important. Among the physical cooling methods, as a commonly used medical supply, the ice blanket cools through the internal circulating water flow and contacts the patient's body to achieve the cooling effect, and is widely used in clinical practice.

[0004] However, most of the current medical ice blankets on the market are designed in a mattress style and are mainly placed under the patient's body. Although they can effectively reduce the patient's body temperature, in cases of central hyperthermia caused by craniocerebral injury, this design lacks targeted cooling measures for the head. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a medical ice blanket to solve the technical problems mentioned in the above background art.

[0006] The utility model provides a medical ice blanket, comprising:

[0007] A blanket body, in which a first cooling pipe is arranged. One end of the first cooling pipe is communicated with a liquid inlet pipe, and the other end is communicated with a liquid outlet pipe. Both the liquid inlet pipe and the liquid outlet pipe are arranged outside the blanket body.

[0008] A cooling cap, in which a second cooling pipe is arranged. The liquid inlet end and the liquid outlet end of the second cooling pipe are respectively communicated with the first cooling pipe through a first external connecting pipe.

[0009] Further, in the medical ice blanket, the first cooling pipe includes a straight pipe section and a bent pipe section. The straight pipe sections are arranged at intervals along the length direction of the blanket body, and the bent pipe section is communicated between two adjacent straight pipe sections to connect multiple straight pipe sections in series.

[0010] Further, in the medical ice blanket, the straight pipe sections and the bent pipe section together form a continuously bent S shape.

[0011] Further, in the medical ice blanket, a branch pipe section is also communicated between two adjacent straight pipe sections.

[0012] Furthermore, for the medical ice blanket, the cooling cap includes a cap portion and a cap circumference portion. The second cooling pipe includes a first spiral pipe section disposed within the cap portion and a second spiral pipe section disposed within the cap circumference portion. The first spiral pipe section and the second spiral pipe section are connected in series as a single unit. The liquid inlet end and the liquid outlet end of the second cooling pipe are respectively connected to the straight pipe section through a first external connecting pipe.

[0013] Furthermore, for the medical ice blanket, the straight pipe section connected to the first external connecting pipe is partitioned into a first section and a second section. One end of the first section is connected to the liquid inlet pipe, and the other end is connected to the liquid inlet end of the first spiral pipe section through the first external connecting pipe. One end of the second section is connected to the first external connecting pipe at the liquid outlet end of the second cooling pipe, and the other end is connected to the bent pipe section.

[0014] Furthermore, for the medical ice blanket, the medical ice blanket further includes a plurality of local cooling structures. The local cooling structure includes a cold compress patch, a strap, and a third spiral pipe section. The third spiral pipe section is disposed within the cold compress patch.

[0025] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. Specific embodiments

[0026] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided so that the disclosure of the present invention is thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention belongs. The terms used herein in the description of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] Please refer to Figures 1 to 5 , the medical ice blanket in the present invention includes a blanket body 10 and a cooling cap 20. A first cooling pipeline is provided in the blanket body 10. One end of the first cooling pipeline is communicated with a liquid inlet pipe 31, and the other end is communicated with a liquid outlet pipe 32. Both the liquid inlet pipe 31 and the liquid outlet pipe 32 are arranged outside the blanket body 10; a second cooling pipeline is provided in the cooling cap 20, and the liquid inlet end and the liquid outlet end of the second cooling pipeline are respectively communicated with the first cooling pipeline through a first external connecting pipe 25.

[0030] It can be understood that the second cooling pipe in the cooling cap 20 is connected to the first cooling pipe through the first external connecting pipe 25, so that the coolant can circulate between the cooling cap 20 and the blanket body 10. While reducing the patient's body temperature, additional cooling treatment is also carried out on the head part, providing a more comprehensive and detailed cooling measure for the patient.

[0031] It should be noted that the liquid inlet pipe 31 and the liquid outlet pipe 32 are used to externally connect a compression refrigeration device (not shown in the figure). Through the compression refrigeration device, the coolant circulates in the first cooling pipe and the second cooling pipe, so that the blanket surface and the cooling cap 20 are maintained at a lower temperature level, realizing the cooling of the patient's body and head part.

[0032] Refer to Figure 2 , the first cooling pipe includes a straight pipe section 301 and a bent pipe section 302. The straight pipe section 301 is provided with a plurality of intervals along the length direction of the blanket body 10. The bent pipe section 302 is connected between two adjacent straight pipe sections 301 to connect a plurality of the straight pipe sections 301 in series. Specifically, the straight pipe section 301 and the bent pipe section 302 together form a continuously bent S shape, thereby increasing the flow path of the coolant in the pipe, making the coolant stay in the pipe for a longer time, and also having a longer heat exchange time with the pipe wall, effectively improving the cooling effect.

[0033] In practical applications, when the patient lies on the blanket body 10, the straight pipe section 301 inside it will be squeezed, which may cause the coolant in the first cooling pipe to not flow normally. To overcome this technical problem, in this embodiment, a branch pipe section 303 is also connected between two adjacent straight pipe sections 301 to drain the coolant in the first cooling pipe through the branch pipe section 303 when the straight pipe section 301 is squeezed, avoiding the situation where the coolant cannot flow and circulate.

[0034] Combined with Figure 3 and Figure 4 , the cooling cap 20 includes a cap part 21 and a cap circumference part 22. The second cooling pipe includes a first spiral pipe section 23 provided in the cap part 21 and a second spiral pipe section 24 provided in the cap circumference part 22. Among them, the first spiral pipe section 23 and the second spiral pipe section 24 are connected in series as a whole. The liquid inlet end and the liquid outlet end of the second cooling pipe are respectively connected to the straight pipe section 301 through the first external connecting pipe 25.

[0035] Specifically, in this embodiment, the cap portion 21 and the cap circumference portion 22 are sewn together as a double-layer design, and the first spiral pipe section 23 and the second spiral pipe section 24 are arranged therein to respectively correspond to the top of the patient's head and the head circumference position. When the cooling liquid is introduced into the liquid inlet pipe 31, the cooling liquid flows through the first spiral pipe section 23 and the second spiral pipe section 24 to achieve all-round cooling of the patient's head.

[0036] Further, the straight pipe section 301 communicated with the first external connection pipe 25 is partitioned into a first section 41 and a second section 42. One end of the first section 41 is communicated with the liquid inlet pipe 31, and the other end is communicated with the liquid inlet end of the first spiral pipe section 23 through the first external connection pipe 25. One end of the second section 42 is communicated with the first external connection pipe 25 at the liquid outlet end of the second cooling pipe, and the other end is communicated with the elbow pipe section 302. It can be understood that when the liquid inlet pipe 31 starts to inject the cooling liquid, these cooling liquids will first quickly fill the second cooling pipe through the first section 41. This is because the second section 42 has not been touched by the cooling liquid at this moment, thus ensuring that the cooling liquid preferentially and completely flows to the second cooling pipe. This design enables the patient's head to quickly feel the cooling effect, which is particularly effective for situations that require urgent reduction of the head temperature, such as craniocerebral injury or high fever. This can not only relieve the discomfort of the patient, but also may help to stabilize the condition and provide more favorable conditions for subsequent treatment. More critically, this design also cleverly avoids the cooling liquid that has exchanged heat with the patient's body from entering the second cooling pipe. When the cooling liquid passes through the first cooling pipe in contact with the patient's body, its temperature will rise. If this part of the cooling liquid enters the second cooling pipe again, it will undoubtedly reduce the cooling effect of the cooling cap 20. However, due to the design of the second section 42, this part of the already heated cooling liquid will be guided to the elbow pipe section 302 and then flow to other parts of the first cooling pipe, rather than flowing back to the second cooling pipe. Therefore, this design not only ensures the effectiveness of the cooling cap 20 during the treatment process, but also enhances its stability.

[0037] Further, referring to Figure 1 and Figure 5 , the medical ice blanket further includes a plurality of local cooling structures. The local cooling structure includes a cold compress patch 51, a strap 52 and a third spiral pipe section 53. The third spiral pipe section 53 is arranged in the cold compress patch 51. The liquid inlet end and the liquid outlet end of the third spiral pipe section 53 are respectively communicated with the first cooling pipe through a second external connection pipe 54. The strap 52 is arranged on both sides of the cold compress patch 51. In practical applications, the cold compress patch 51 can be fixed to positions rich in large blood vessels such as the patient's armpits, groins, popliteal fossae, and cubital fossae through the strap 52. When the cooling liquid is introduced into the liquid inlet pipe 31, a part of the cooling liquid will flow through the third spiral pipe section 53 through the second external connection pipe 54, so that the cold compress patch 51 can achieve local cooling of specific positions of the patient's body, further improving the cooling treatment effect.

[0038] In this embodiment, the number of the local cooling structures can be set as required, which is only an example rather than a limitation.

[0039] Furthermore, in this embodiment, the first cooling pipe is a flat pipe. It can be understood that the structural design of the flat pipe can increase the contact area with the patient's body, thereby facilitating the heat conduction between the coolant and the body and enhancing the cooling effect of the blanket 10 on the human body.

[0040] In summary, for the medical ice blanket in the above embodiments of the present utility model, the second cooling pipe in the cooling cap 20 is connected to the first cooling pipe through the first external connecting pipe 25, so that the coolant can circulate between the cooling cap 20 and the blanket 10. While reducing the patient's body temperature, an additional cooling treatment is also performed on the head part, providing a more comprehensive and detailed cooling measure for the patient.
