Detailed implementation mode

[0039] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0040] Embodiment 1:

[0041] Please refer to Figures 1-4 As shown, in this embodiment, a drainage device for the liver and gallbladder is provided, including a liquid inlet pipe 1, a connecting pipe 2, and a drainage catheter 3. The connecting pipe 2 is inserted into the drainage catheter 3 and fixedly installed in the liquid inlet pipe 1. A detachable clamping assembly 4 is installed on the liquid inlet pipe 1. The detachable clamping assembly 4 includes a fixed block 401 sleeved outside the liquid inlet pipe 1 and anti-slip pads 402 symmetrically clamped outside the drainage catheter 3. Symmetrically installed on the top of the fixed block 401 are pressing plates 403 adhered to the anti-slip pads 402. Symmetrically installed on the side wall of one pressing plate 403 are snap rings 404, and symmetrically installed on the side wall of the other pressing plate 403 are snap plates 405 inserted into the snap rings 404.

[0042] One aspect of the application of this embodiment is as follows: When it is necessary to quickly fix the drainage catheter 3, the connecting pipe 2 is inserted through the port of the drainage catheter 3, and the drainage catheter 3 is sleeved outside the connecting pipe 2. At this time, the drainage catheter 3 is placed between the two anti-slip pads 402. The surface of the anti-slip pad 402 facing the drainage catheter 3 is provided with an arc surface and has the same outer diameter as the drainage catheter 3. By simultaneously pinching the two pressing plates 403 with the thumb and index finger of the same hand, the snap plates 405 on the same side are aligned with the snap rings 404, and while pressing the pressing plates 403, the two pressing plates 403 approach each other. The two pressing plates 403 drive the snap rings 404 and the snap plates 405 to approach each other. The snap plate 404 penetrates into the snap ring 405, and the protruding straight side wall of the snap plate 405 is clamped with the snap ring 404. The fixation between the snap ring 404 and the snap plate 405 drives the fixation between the two pressing plates 403. The fixation between the two pressing plates 403 can drive the fixation between the two anti-slip pads 402. When the two pressing plates 403 approach each other, they drive the two anti-slip pads 402 to approach each other. The connecting pipe 2 is made of a rigid material, and the connecting pipe 2 can support the drainage catheter 3. The two anti-slip pads 402 simultaneously squeeze the drainage catheter 3, and the drainage catheter 3 squeezes the connecting pipe 2. The friction between the anti-slip pad 402 and the drainage catheter 3 increases, and the friction between the connecting pipe 2 and the drainage catheter 3 increases, enabling the connection between the drainage catheter 3 and the connecting pipe 2 to be more secure. The liquid drained from the patient's body enters the connecting pipe 2 through the drainage catheter 3, and the liquid in the connecting pipe 2 can enter the liquid inlet pipe 1. It should be noted that all electrical devices involved in this application can be powered by a storage battery or an external power supply.

[0043] Example 2:

[0044] As Figure 1 and Figures 3-4 shown, an installation groove 5 is formed on the snap ring 404 of this embodiment.

[0045] In this embodiment, the installation groove 5 enables the snap ring 404 to form an open ring.

[0046] As Figures 3-4 shown, a connecting column 6 is adhesively bonded in the installation groove 5 of this embodiment.

[0047] In this embodiment, the diameter of the connecting column 6 is relatively small. Both ends of the connecting column 6 are connected to the opposite two side walls of the installation groove 5 by adhesive. The connecting column 6 can prevent the installation groove 5 from unfolding, can prevent the snap ring 404 from unfolding, and can prevent the card plate 405 in use from detaching from the snap ring 404.

[0048] As Figures 3-4 shown, a pull ring 7 is fixedly installed on the side wall of the snap ring 404 of this embodiment.

[0049] In this embodiment, when it is necessary to disassemble the drainage catheter 3, pull the two pull rings 7 simultaneously to move the two pull rings 7 away from each other. The pull ring 7 drives the side walls of the snap ring 404 connected thereto to move away from each other. The snap ring 404 drives the side wall of the installation groove 5 away from the connecting column 6, and the adhesive between the installation groove 5 and the connecting column 6 is disconnected. The snap ring 404 can be unfolded, and the card plate 405 in the snap ring 404 can be quickly pulled out. The connection between the snap ring 404 and the card plate 405 is lost, which can drive the fixation between the two pressing plates 403 to be lost. The loss of fixation between the two pressing plates 403 can drive the fixation between the two anti-slip pads 402 to be lost. The drainage catheter 3 loses the extrusion of the anti-slip pads 402, and the drainage catheter 3 can be conveniently pulled out quickly.

[0050] As Figures 1-2 shown, a drainage device body 8 is fixedly installed at the bottom of the liquid inlet pipe 1 of this embodiment. An outlet pipe 801 is fixedly installed at the bottom of the drainage device body 8, and an outlet valve 802 is installed in the outlet pipe 801.

[0051] In this embodiment, the liquid in the liquid inlet pipe 1 can enter the drainage device body 8. The drainage device body 8 can collect the drained liquid. When the outlet valve 802 is opened, the outlet pipe 801 can be opened, and the liquid in the drainage device body 8 can flow out from the outlet pipe 801 through the outlet valve 802.

[0052] As Figure 1 shown, a check valve 101 is installed in the liquid inlet pipe 1 of this embodiment.

[0053] In this embodiment, the liquid in the liquid inlet pipe 1 can enter the drainer body 8 through the check valve 101, and the check valve 101 can prevent the liquid in the drainer body 8 from flowing back into the liquid inlet pipe 1.

[0054] As Figure 1 shown, hooks 9 are symmetrically installed on the side wall of the fixing block 401 of this embodiment.

[0055] In this embodiment, the hooks 9 are hung on a medical hanger, which can drive the fixing block 401 to be hung. The fixing block 401 can drive the liquid inlet pipe 1 to be hung, and the liquid inlet pipe 1 can drive the drainer body 8 to be hung, which can prevent the drainer body 8 from tilting.

[0056] The present utility model is not limited to the above embodiments. Any person should know that the structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
