detailed description

The utility model will be further described in detail below in conjunction with the examples, but the implementation of the utility model is not limited thereto.

Example 1:

As shown in Figure 1, in this embodiment, a new type of drainage bag includes a drainage tube and a main body of the drainage bag. In this embodiment, the drainage tube also includes a side tube 4, which is in sealing communication with the body cavity section 1, and the free end of the side tube 4 is provided with an A interface 61, and the A interface 61 is sealingly connected to the dosing device 6. In this embodiment In the example, the side tube 4 is selected as the drug dosing channel, and the side tube 4 can repeatedly inject drugs or extract pleural and ascites, thereby reducing the medical expenses of the patient.

As shown in Figure 3, the main body of the drainage bag includes a connecting pipe 8, a drainage bag 13 and a drain pipe 15, and the connecting pipe 8, the drainage bag 13 and the drain pipe 15 are connected in sequence. There is a B port 71 at the end of the connecting pipe 8, a C port 7 is provided at the free end of the connecting pipe 8, and the B port 71 is in sealing connection with the C port 7. The connecting pipe 8 is provided with a one-way valve 10, as shown in Fig. 4 and Fig. The directional valve 10 includes a valve ring 101 and several pouch-shaped valves 102 installed on the valve ring 101. The valve 102 is provided with a ridge 103 for supporting the valve 102. The convex surface of the valve 102 points to the drainage tube. In this embodiment, The valve 102 is made of silica gel and has three valves. The valve 102 is evenly distributed on the valve ring 101 and divides the valve ring 101 equally. The ridges 103 on two adjacent valve rings 101 can be tightly closed, so that This enables the valve 102 to be supported.

In this embodiment, the connecting pipe 8 is provided with a flow control switch 9, which can reasonably adjust the flow rate of the liquid drawn out of the patient's body through the control switch 9, so as to avoid the discomfort of the patient caused by too large flow rate or the drainage caused by too small flow rate. low efficiency.

In this embodiment, the flow control switch 9 is located between the C interface 7 and the one-way valve 10 .

In this embodiment, the main pipe 2 is provided with an A switch 3 , the side pipe 4 is provided with a B switch 5 , and the discharge pipe 15 is provided with a C switch 14 .

In this embodiment, the two sides of the drainage bag 13 are provided with belt holes 12, and the side where the drainage bag 13 is connected to the connecting pipe 8 is provided with a hanging belt 11. By setting the belt holes 12, the utility model can be tied to the Then tie the belt on the patient's waist, so that the patient can carry the drainage bag to go out.

In this embodiment, the body cavity section 1 is provided with a scale, and the zero point of the scale begins at the beginning of the body cavity section 1, which can facilitate the observation of the length of the body cavity section 1 entering the patient's body, so as to avoid the entry length being too long or too short and cause inconvenience.

The working process of the utility model is as follows: firstly close the A switch 3 and the B switch 5, tighten the heparin cap on the A interface 61, put the body cavity section 1 of the drainage tube into the body cavity according to the specific situation and fix it, pass through the body cavity section 1 The scale on the upper body can read the length of the body cavity segment 1 that enters the patient's body. When it is not necessary to inject medicine into the patient's body or draw liquid, keep the B switch 5 normally closed. Connect the connecting pipe 8 through the main pipe joint B, turn on the A switch 3 and the flow control switch 9, and the liquid is drained out due to the certain hydraulic pressure in the patient's body, and enters the connecting pipe 8 through the body cavity section 1 until the one-way valve 10.

Because the valve 102 made of silicone is in the shape of a baby bag and the convex surface points to the drained liquid, the liquid pushes the valve 102 after flowing to the one-way valve 10, and the one-way valve 10 is naturally opened, so that the liquid can circulate and enter the drainage bag 13 until The liquid is drained.

If the liquid in the drainage bag 13 backflows, when the liquid flows to the one-way valve 10, the liquid will enter the valve 102. Since the valve 102 is made of silica gel and has good elasticity, the liquid entering the valve 102 can make the valve 102 close naturally and tightly. , and due to the support of the ridge 103, the valve 102 will not open, thereby preventing the liquid from flowing back into the patient's body.

Example 2:

In this embodiment, a new type of drainage bag includes a drainage tube and a drainage bag main body. The drainage tube includes a body cavity section 1 and a main tube 2. The main tube 2 is in sealing communication with the body cavity section 1. In this embodiment, the drainage tube also includes The side pipe 4 is in sealing communication with the body cavity section 1, and the free end of the side pipe 4 is provided with an A interface 61, and the A interface 61 is sealed and connected with the dosing device 6. In this embodiment, the side pipe is selected as the dosing channel, The side tube can repeatedly inject medicine or extract pleural and ascites, and reduce the patient's medical expenses. As shown in Figure 6, in the present embodiment, the A interface 61 is a tapered interface with its small end facing outwards. There is an installation hole matched with the A interface 61, and the diameter of the installation hole is larger than the diameter of the small end of the A interface 61 and smaller than the diameter of the large end of the A interface 61. During installation, the dosing device 6 is installed with the A interface 61. Since the diameter of the mounting hole is smaller than the diameter of the large end of the A interface 61, part of the A interface 61 is interference fit with the mounting hole, and because the A interface 61 is plastic with A certain degree of elasticity enables the medicine feeding device 6 to be closely connected to the A interface 61, the connection is reliable, the sealing performance is high, and the installation and disassembly can be performed quickly.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification or equivalent change made to the above embodiments according to the technical essence of the utility model falls within the scope of the present utility model. Within the protection scope of the present utility model.
