DETAILED DESCRIPTION

[0029] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0030] As attached Figure 1 To Attachment Figure 5 As shown: A bleeding alarm device for dialysis includes a base 1, a first receiving groove 2 is provided along the center of the bottom surface of the base 1, a moisture sensitive sheet 21 is arranged in the first receiving groove 2, and the lower end of the moisture sensitive sheet 21 is protruding and arranged on the bottom surface of the base 1. When the user wears the base 1 to the wound position of the arm, the moisture sensitive sheet 21 can detect the bleeding situation. A second receiving groove 3 with a frame-shaped structure is provided along the bottom surface of the base 1 at the outer side of the first receiving groove 2, wherein the second receiving groove 3 is used to surround the first receiving groove 2, and a frame-shaped installation frame 4 is adapted and engaged in the second receiving groove 3, and the installation frame 4 has a frame-shaped installation groove 41 along the bottom surface, and an air bag layer 42 is installed in the installation groove 41, and the air bag layer 42 is mainly used to press the bleeding area of ​​the wound and stop bleeding.

[0031] Furthermore, the thickness of the mounting frame 4 is smaller than the thickness of the second receiving groove 3. Through this design, when the user wears the base 1 on the wound area of ​​the arm, it can avoid direct contact between the airbag layer 42 and the skin, thereby reducing the pressure on the wound and improving the wearing comfort of the patient.

[0032] Furthermore, a first slope 31 is formed along the inner end surface of the inner wall of the second accommodating groove 3, and a second slope 32 is formed on the outer end surface of the inner wall of the second accommodating groove 3, wherein the first slope 31 and the second slope 32 are both arranged as slope structures. Through the design of the slope structure, when the airbag layer 42 gradually expands, the left and right parts of the airbag layer 42 will contact the slope structure. When in contact, the slope structure will form a greater pressure on the inflated airbag, so that the pressure can be applied to the airbag, and then the left and right parts of the airbag can have a better pressing and hemostatic effect when pressing the skin, while the middle part of the airbag can apply a uniform pressing force.

[0033] Furthermore, the internal area of ​​the first accommodating groove 2 is larger than the area of ​​the moisture-sensitive sheet 21. Through this design, since the moisture-sensitive sheet 21 is protruding from the bottom of the base 1, when the base 1 and the moisture-sensitive sheet 21 contact the skin together, a certain gap will be formed between the moisture-sensitive sheet 21 and the first accommodating groove 2. When the airbag is inflated, it can drill into this gap and obtain a stronger pressing force, thereby enhancing the hemostatic effect on the wound. In addition, the protruding design of the moisture-sensitive sheet 21 makes it easier to form a close contact with the skin, thereby more accurately sensing the moisture changes of the wound.

[0034] Furthermore, an air inlet pipe 43 and an air outlet pipe 44 are respectively arranged horizontally on the left and right sides of the outer side of the mounting frame 4, wherein one end of the air inlet pipe 43 and the air outlet pipe 44 are connected to the inside of the airbag layer 42, so that the external gas can expand the airbag layer 42 through the air inlet pipe 43, and similarly, the arrangement of the air outlet pipe 44 can release the gas in the airbag layer 42. In addition, in order to facilitate the blocking of the gas, a plug is also threadedly arranged at the tail end of the air outlet pipe 44.

[0035] like Figures 1 to 3 As shown, a micro air pump 5 is arranged on the top surface of the base 1, and a connecting pipe 51 is arranged inside the base 1, wherein one end of the connecting pipe 51 is connected to the air outlet end of the micro air pump 5, and the other end is relatively arranged on the left side of the base 1. At the same time, a connecting groove 33 is opened on the inner wall of the left side of the base 1 to the second accommodating groove 3, and the connecting groove 33 is arranged opposite to the connecting pipe 51, and the inside of the connecting groove 33 is connected to the bottom surface of the base 1, so that the adapter of the air inlet pipe 43 can be put into the connecting groove 33, and after being put in, the air inlet pipe 43 can be opposite to the connecting pipe 51. Finally, a connector 52 is threadedly provided at one end of the connecting tube 51 facing the air inlet pipe 43. The connector 52 is a circular tubular structure, and then one end of the connector 52 is threadedly connected to the outer wall of the air inlet pipe 43. Through this design, the connecting tube 51 and the air inlet pipe 43 can be connected through the connector 52. After the connection, it is convenient for the micro air pump 5 to inject gas into the connecting tube 51 to expand the airbag layer 42.

[0036] Furthermore, a sub-connecting groove 33 is opened from the right side surface of the base 1 to the inner wall of the second accommodating groove 3, and the interior of the sub-connecting groove 33 is connected to the bottom surface of the base 1. The sub-connecting groove 33 is mainly used to place the air outlet pipe 44. During installation, one end of the air outlet pipe 44 can be installed in the sub-connecting groove 33.

[0037] Furthermore, at least two buzzers 61 are provided on the top surface of the base 1, wherein the buzzers 61 are mainly used to warn of bleeding. When the moisture sensitive sheet 21 senses bleeding, the buzzer 61 gives an alarm. In addition, to facilitate the operation of the above-mentioned electrical equipment, a controller 6 is also provided in the base 1, wherein the controller 6 is any one of a microcontroller 6 or a single-chip microcomputer, and the controller 6 is electrically connected to the moisture sensitive sheet 21, the micro air pump 5 and the buzzer 61. When in use, the bleeding is first sensed by the moisture sensitive sheet 21, and then the controller 6 receives the sensing signal of the moisture sensitive sheet 21, thereby triggering the buzzer 61 to sound, and then the micro air pump 5 inflates and expands the airbag. It should be noted that in order to avoid the continuous operation of the buzzer 61 and the micro air pump 5, the start-up time needs to be pre-set on the controller 6. Furthermore, in order to facilitate the normal operation of the above-mentioned electrical equipment, a lithium battery is also arranged on the base 1, and the lithium battery mainly supplies power to the moisture sensitive sheet 21, the micro air pump 5, the controller 6 and the buzzer 61.

[0038] like Figure 1 As shown, connecting ears 11 are correspondingly provided along the front side and the rear side of the base 1, and the connecting ears 11 include a first connecting ear and a second connecting ear. The first connecting ear and the second connecting ear are respectively detachably connected with a first strap 12 and a second strap 13. For example, the first strap 12 and the second strap 13 can be installed at the corresponding connecting ears 11 by screws. Through this design, it is convenient to disassemble the base 1 and the strap, and it is convenient for later maintenance and replacement after disassembly.

[0039] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed in the present application, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application. Therefore, the protection scope of the present application should be described in the protection scope of the claims.
