Detailed implementation manners

[0024] Next, the technical solutions in this embodiment will be clearly and completely described in conjunction with the accompanying drawings in this embodiment. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 shown, this embodiment discloses a drainage tube anti-pulling alarm device, including a bracket 1 and a trigger ring 2. The bracket 1 is sleeved around the drainage tube 101. One end of the drainage tube 101 is inside the patient's body, and the bracket 1 is outside the patient's body. The bracket 1 includes a bottom plate 11, a housing 12, and a support rod 14. The bracket 1 is generally frustum-shaped. The bottom plate 11 and the housing 12 are connected by a plurality of support rods 14. The drainage tube 101 penetrates through the housing 12. The bottom plate 11 is annular, and the diameter of the bottom plate 11 is larger than the diameter of the housing 12. The bottom plate 11 is used to adhere to the patient's skin. Since the drainage tube 101 passes through the housing 12, when the drainage tube 101 bends, it will exert pressure on the housing 12. The larger bottom plate 11 than the housing 12 can better support the housing 12 and make the whole bracket 1 more stable.

[0026] The bottom plate 11 includes an annular plate 111. The annular plate 111 is provided with a plurality of thinning portions 1111. The plurality of thinning portions 1111 are evenly distributed in a ring shape. The annular plate 111 between two adjacent thinning portions 1111 forms a dividing plate 1112. The upper end surface of the dividing plate 1112 is fixedly connected to a support rod 14, and a rubber pad 113 is installed on the lower end surface of the dividing plate 1112, so that there is a soft contact between the bottom plate 11 and the patient's skin. Since the positions where the patient inserts the drainage tube 101 are different, the design of the thinning portions 1111 enables the dividing plates 1112 to deform relative to each other, and can better fit the skin of different parts of the patient. The bottom plate 11 is provided with adhesive tapes 112. The adhesive tapes 112 are evenly distributed in a ring shape on the outer periphery of the bottom plate 11. The adhesive tapes 112 can increase the attachment area between the bottom plate 11 and the patient's skin. The entire bracket 1 is fixed on the patient's skin through the rubber pad 113 at the bottom of the bottom plate 11 and the adhesive tapes 112 on the outer periphery of the bottom plate 11. The hollow part in the middle of the bracket 1 can be covered with a gauze to protect the wound.

[0027] The trigger ring 2 includes a first half-ring 22 and a second half-ring 23. One end of the first half-ring 22 is hingedly connected to one end of the second half-ring 23 through a hinge point 25. The movable ends of the first half-ring 22 and the second half-ring 23 are connected by a buckle. The first half-ring 22 and the second half-ring 23 form a circular ring. The free ends of the first half-ring 22 and the second half-ring 23 can be opened. After the first half-ring 22 and the second half-ring 23 are opened, they can be looped around the drainage tube 101. Elastic pads 26 are installed on the inner side walls of the first half-ring 22 and the second half-ring 23. The elasticity of the elastic pads 26 increases the friction between the trigger ring 2 and the drainage tube 101, so that the trigger ring 2 can be firmly fixed on the drainage tube 101.

[0028] The trigger ring 2 is located between the bottom plate 11 and the housing 12. The trigger ring 2 is provided with a guide rod 21. One end of the guide rod 21 is installed on the trigger ring 2 by a thread. The guide rod 21 extends towards the housing 12. The housing 12 is provided with a guide hole 123. The guide rod 21 passes through the guide hole 123. After the trigger ring 2 is fixed on the drainage tube 101, the guide rod 21 passes through the housing 12 and is fixed on the trigger ring 2. In this embodiment, in order to make the connection between the trigger ring 2 and the housing 12 stable through the guide rod 21, the number of the guide rods 21 is set to three. Two of the guide rods 21 are located on the first half-ring 22, and the other guide rod 21 is located on the second half-ring 23. The three guide rods 21 are evenly distributed in a ring shape. When the drainage tube 101 is pulled out from the bottom plate 11 towards the housing 12, the trigger ring 2 can approach the housing 12 through the guidance of the guide rod 21.

[0029] On the end face of the housing 12 facing the trigger ring 2, a first trigger terminal 151 is provided. An annular cavity 121 is formed inside the housing 12. A circuit board 15, an alarm 16, and a battery 17 are installed in the annular cavity 121. The first trigger terminal 151 is located on the lower end face of the circuit board 15. The first trigger terminal 151 penetrates and extends beyond the lower end face of the housing 12. When the two first trigger terminals 151 are connected, the alarm 16 can be triggered to emit an alarm sound, indicating that the drainage tube 101 has been pulled out a certain distance, informing the patient and the doctor that the suture fixing the drainage tube 101 has become loose and needs to be fixed again.

[0030] More preferably, a plurality of through holes 122 are provided on the side wall of the housing 12. The positions of the through holes 122 correspond to the positions of some of the alarms 16 inside the housing 12. The sound of the alarm 16 can be transmitted to the outside through the through holes 122, emitting a clearer alarm prompt sound.

[0031] On the end face of the trigger ring 2 facing the housing 12, a second trigger terminal 24 is provided. The trigger ring 2 includes a metal sheet 241. The metal sheet 241 is fixedly installed on the trigger ring 2. The metal sheet 241 is integrally injection-molded in the second half-ring 23. The metal sheet 241 is provided with two second trigger terminals 24. The two second trigger terminals 24 extend beyond the upper end face of the trigger ring 2. When the drainage tube 101 is pulled out from the bottom plate 11 towards the housing 12, the trigger ring 2 approaches the housing 12. The two second trigger terminals 24 are conducted through the metal sheet 241. When the second trigger terminal 24 contacts the first trigger terminal 151, the two first trigger terminals 151 can be conducted, and at the same time, the housing 12 can block the trigger ring 2 to prevent the drainage tube 101 from being pulled out further, which can play a certain blocking role.

[0032] A top cover 13 is installed at the upper opening of the housing 12. The top cover 13 closes the annular cavity. The top cover 13 is provided with a hole position that can communicate with the guide hole 123. When installed, the guide rod 21 penetrates the top cover 13 and extends into the guide hole 123.

[0033] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
