DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1-Figure 3 The backpack-type negative pressure suction disk shown includes: an open backpack body, a negative pressure suction disk 1, shoulder straps 2 and a waist belt 3; the open backpack body includes a top plate 4, a bottom plate 5 and a back plate 6; the top plate 4 is connected to the top of the back plate 6, the bottom plate 5 is connected to the bottom of the back plate 6, and the top plate 4 and the bottom plate 5 are arranged opposite to each other; the bottom plate 5 is provided with a drainage port 7; the bottom plate 5 is also provided with a plug 8 for closing or opening the drainage port 7.

[0018] There are two shoulder straps 2, which are respectively arranged on both sides of the back plate 6. When the present embodiment is in use, the open backpack body is carried on the patient's abdomen by the shoulder straps 2. In order to fix the open backpack body more firmly, waist belts 3 are arranged on both sides of the open backpack body. The waist belt 3 includes a first sheet and a second sheet. One end of the first sheet is connected to one side of the back plate 6, and one end of the second sheet is connected to the other side of the back plate 6. The ends of the first sheet and the second sheet are respectively provided with matching Velcro 16. Figure 3 As shown, when in use, the first sheet is first separated from the second sheet, and after the open backpack body is carried on the abdomen using the shoulder strap 2, the first sheet and the second sheet are respectively wrapped around the patient's back waist, and the first sheet and the second sheet are adhered and fixed using the Velcro 16. Under the joint action of the shoulder strap 2 and the waist belt 3, the open backpack body is effectively fixed to the patient's abdomen, and the patient can directly get out of bed and walk or turn over while lying flat.

[0019] In this embodiment, the back plate 6 of the open backpack body is an arc plate, and the top plate 4 and the bottom plate 5 are concentric circular plates of the same size, and the arc length of the arc plate is half of the circumference of the top plate 4 or the bottom plate 5. The arc plate is fixed along the edges of the top plate 4 and the bottom plate 5, so as to form a Figure 3 The structure of the open backpack body can be understood as a notch opened in the side wall of a cylindrical structure with closed ends for placing or taking out the negative pressure suction disc 1.

[0020] The negative pressure suction disk 1 is arranged between the top plate 4 and the bottom plate 5. The diameter of the negative pressure suction disk 1 is smaller than the diameter of the top plate 4 or the bottom plate 5. The negative pressure suction disk 1 is preferably arranged concentrically with the top plate 4 and the bottom plate 5.

[0021] The top of the negative pressure suction disc 1 is provided with a drainage tube 9 connected to its inner cavity, and the bottom of the negative pressure suction disc 1 is provided with a connecting tube 10 connected to its inner cavity, and the connecting tube 10 is inserted into the drainage port 7 of the bottom plate 5. When the plug 8 closes the drainage port 7, the plug 8 is also inserted into the connecting tube 10.

[0022] In this embodiment, the plug 8 is a truncated cone structure, the top of which is inserted into the connecting pipe 10, and the bottom of the plug 8 is connected to a flexible rubber belt, which is connected to the bottom plate 5, so that when the plug 8 is pulled out of the connecting pipe 10 and the drain port 7, the flexible rubber belt hangs the plug 8 at the bottom of the bottom plate 5, and the plug 8 will not be lost. The truncated cone structure of the plug 8 makes it fit more closely with the connecting pipe 10 and the drain port 7.

[0023] A spring 11 is also provided between the top of the negative pressure suction disc 1 and the top plate 4. There are at least two springs 11, which are symmetrically arranged along the circumferential direction of the top of the negative pressure suction disc 1. The compression direction of the spring 11 is consistent with the compression direction of the negative pressure suction disc 1; the top of the spring 11 is fixedly connected to the top plate 4, and the bottom of the spring 11 is pressed against the top of the negative pressure suction disc 1.

[0024] When the negative pressure suction disk 1 is not installed between the top plate 4 and the bottom plate 5, the spring 11 is in a natural state, and the distance between the lower end of the spring 11 and the bottom plate 5 is less than the height of the negative pressure suction disk 1 in the negative pressure state. When the negative pressure suction disk 1 is placed between the top plate 4 and the bottom plate 5, it needs to be compressed.

[0025] The drainage tube 9 is provided with a three-way joint 12 and a tube clamp 13. The tube clamp 13 is used to close or open the drainage tube 9, and in the three-way joint 12, an interface is reserved for adding medicine into the drainage tube 9.

[0026] A hanging bag 14 is provided at the bottom of the bottom plate 5, and a measuring cup 15 is stored in the hanging bag 14. An opening for taking out the measuring cup 15 is provided on one side of the hanging bag 14. An elastic band is provided at the opening edge of the hanging bag 14. When it is necessary to measure the liquid capacity in the negative pressure suction disc 1, the measuring cup 15 in the hanging bag 14 is taken out through the opening of the hanging bag 14, and the measuring cup 15 is placed under the drain port 7. The plug 8 is opened, and the liquid in the negative pressure suction disc 1 is discharged into the measuring cup 15 after passing through the connecting pipe 10 and the drain port 7. The amount of liquid in the negative pressure suction disc 1 can be determined by the measuring scale of the measuring cup 15.

[0027] The connecting tube 10 is closed by the plug 8, one end of the drainage tube 9 is connected to the patient's drainage site, and the negative pressure drainage disk is squeezed to discharge the air inside to form a negative pressure drainage disk. Figure 1 In the negative pressure state shown, the other end of the drainage tube 9 is connected to the top of the negative pressure suction disk 1 for negative pressure drainage. In this state, the bottom of the spring 11 is pressed against the top of the negative pressure suction disk 1, and the spring 11 has a certain compression margin.

[0028] As the negative pressure drainage proceeds, the pressure in the negative pressure drainage disc gradually returns to normal pressure. At the same time, the top of the negative pressure drainage disc gradually rises, and the spring 11 is compressed. Figure 2 Open the plug 8 and press the negative pressure drainage disc downward to discharge the liquid in the negative pressure drainage disc. At the same time, the air in the negative pressure drainage disc is also discharged. When the plug 8 closes the connecting pipe 10 again, the negative pressure drainage pipe 9 is in a negative pressure state again.

[0029] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
