[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments 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 in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1The utility model provides an embodiment: a perianal abscess puncture drainage device, comprising a drainage tube 1, through which pus in a rubber sleeve 41 is discharged or drugs required for treatment are delivered to the patient's wound, an output tube 7 is fixedly connected to the bottom of the drainage tube 1, through which the pus in the drainage tube 1 is delivered to a collection bag 2, a sealing component 5 is provided at the bottom of the output tube 7, through which the gap between the output tube 7 and the collection bag 2 is sealed, a collection bag 2 is provided at the bottom of the sealing component 5, through which the pus in the output tube 7 is collected The outer wall of the output tube 7 is provided with a valve B8, through which the output tube 7 can be opened or closed, the top of the drainage tube 1 is fixedly connected with a delivery tube 9, through which the therapeutic drugs in the storage bag 3 are delivered to the drainage tube 1, the top of the delivery tube 9 is fixedly connected with a storage bag 3, and the storage bag 3 stores therapeutic drugs, the outer wall of the delivery tube 9 is fixedly connected with a valve A6, through which the delivery tube 9 can be opened or closed, and the left end of the drainage tube 1 is provided with an expansion component 4, through which the rubber sleeve 41 is expanded for cutting, and the pus is introduced into the drainage tube 1.

[0032] Reference Figure 1 and Figure 2 The expansion component 4 includes a rubber sleeve 41. Since the rubber sleeve 41 is made of rubber, it can be placed in the patient's abscess cavity for a long time to play a role in cutting and drainage. The rubber sleeve 41 can expand and contract. When the rubber sleeve 41 expands, it can rub and cut the patient's dead flesh. When the rubber 41 contracts, it is convenient for medical staff to place the rubber sleeve into the patient's abscess cavity. The inner wall of the rubber sleeve 41 is provided with an air bag 42. The air bag 42 can expand or contract. When the air bag 42 expands, the protrusion 43 bulges. The right end of the air bag 42 is fixedly connected to a connecting tube 44. Water is injected into the air bag 42 through the connecting tube 44 to expand the air bag 42. The outer wall of the air bag 42 is fixedly connected to a protrusion 43. When the protrusion 43 bulges, the rubber sleeve 41 expands.

[0033] Reference Figure 1 and Figure 2 The right side of the rubber sleeve 41 is fixedly connected to the left end of the drainage tube 1. The rubber sleeve 41 is provided with grid holes, through which the pus in the patient's abscess cavity can be discharged into the drainage tube 1, or the therapeutic drugs in the drainage tube 1 can be evenly delivered to the patient's wound for treatment. The outer wall of the connecting tube 44 penetrates and is fixedly connected to the inner wall of the drainage tube 1.

[0034] Reference Figure 3The sealing assembly 5 includes a clamping ring 51, and a clamping sleeve 53 is inserted into the outer wall of the clamping ring 51. Through the plug-in effect of the clamping ring 51 and the clamping sleeve 53, the collecting bag 2 is installed on the output pipe 7, and the elastic gasket 52 is squeezed at the same time. The inner wall of the clamping sleeve 53 is provided with an elastic gasket 52. When the elastic gasket 52 is squeezed, it expands and deforms to seal the gap between the output pipe 7 and the collecting bag 2. The inner wall of the clamping ring 51 is provided with a clamping assembly 54, and the clamping sleeve 53 is limited by the clamping assembly 54.

[0035] Reference Figure 1 and Figure 2 The outer wall of the rubber sleeve 41 is in a grid shape. By setting the outer wall of the rubber sleeve 41 to a grid shape, when the rubber sleeve 41 is expanded, the rubber sleeve 41 is rotated to rub and cut the patient's pus cavity necrotic flesh. There are multiple groups of protrusions 43, and the multiple groups of protrusions 43 are evenly distributed along the outer wall of the airbag 42. By providing multiple protrusions 43, the size of the rubber sleeve 41 when expanded is more uniform. The top of the protrusion 43 is arc-shaped. By setting the protrusion 43 to an arc shape, the protrusion 43 and the inside of the rubber sleeve 41 are more closely fitted.

[0036] Reference Figure 1 and Figure 3 The inner wall of the clamping ring 51 is fixedly connected to the outer wall of the output tube 7, and the clamping ring 51 is prevented from falling off by the fixing effect of the clamping ring 51. The bottom of the clamping sleeve 53 is fixedly connected to the top of the collecting bag 2, and the clamping sleeve 53 is prevented from falling off by the fixing effect of the clamping sleeve 53. The clamping assembly 54 includes a wedge block 541, and the outer wall of the wedge block 541 is elastically connected to the inner wall of the clamping ring 51 by a limiting spring 542. Through the elastic force of the limiting spring 542, the wedge block 541 always maintains a clamping effect with the clamping groove 543 when not affected by external force, thereby limiting the clamping sleeve 53. The outer wall of the clamping sleeve 53 is provided with a clamping groove 543.

[0037] Reference Figure 3 One end of the limit spring 542 is fixedly connected to the inner wall of the retaining ring 51, and the other end of the limit spring 542 is fixedly connected to the outer wall of the wedge block 541. The fixing effect of the limit spring 542 keeps the wedge block 541 fixed to prevent the wedge block 541 from falling off. The outer wall of the wedge block 541 is slidably connected to the inner wall of the retaining ring 51. The sliding effect of the wedge block 541 allows the wedge block 541 to be engaged or released from the slot 543. The outer wall of the wedge block 541 is engaged with the inner wall of the slot 543. The engaging effect of the wedge block 541 and the slot 543 allows the retaining ring 51 to limit the sleeve 53.

[0038] Working principle: When in use, the medical staff closes valve A6 to close the delivery tube 9, and opens valve A6 to open the output tube 7. The medical staff inserts the drainage tube 1 into the patient's abscess cavity, and places the rubber sleeve 41 in the patient's abscess cavity. The pus in the abscess cavity flows into the drainage tube 1 through the grid holes on the rubber sleeve 41, and the pus is transported to the output tube 7 through the drainage tube 1, and the pus is transported to the collection bag 2 through the output tube 7 for collection.

[0039] Medical staff inject water into the connecting tube 44, and then transport the water into the airbag 42 through the connecting tube 44, so that the airbag 42 expands, and at the same time, the protrusion 43 set on the airbag 42 bulges, and the rubber sleeve 41 expands through the protrusion 43, so that the outer wall of the rubber sleeve 41 fits with the inner wall of the patient's abscess cavity. The medical staff rotates the drainage tube 1, drives the rubber sleeve 41 to rotate, and cuts the dead flesh in the patient's abscess cavity through the grid-like outer wall. When the cutting is completed, the medical staff closes valve B8 and opens valve A6, so that the therapeutic drug in the storage bag 3 is transported from the drainage tube 1 to the patient's abscess cavity to treat the patient's wound. When the drug coverage is completed, the staff drains the water in the airbag 42, so that the airbag 42 shrinks, drives the protrusion 43 to shrink, and at the same time shrinks the rubber sleeve 41, and takes out the drainage tube 1 and the rubber sleeve 41.

[0040] When the collecting bag 2 is full or needs to be replaced, the medical staff presses the wedge block 541 to release the clamping effect of the wedge block 541 on the slot 543 and release the limiting effect on the sleeve 53. The medical staff removes the collecting bag 2 and installs the replaced collecting bag 2 on the output tube 7, so that the sleeve 53 is plugged into the retaining ring 51 and the elastic gasket 52 is squeezed to expand and deform, thereby sealing the gap between the collecting bag 2 and the output tube 7. Under the elastic force of the limiting spring 542, the wedge block 541 is clamped into the slot 543 to limit the sleeve 53 and keep the collecting bag 2 fixed.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
