Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a pre-operative flushing device for hemorrhoids. Background Art

[0002] In the medical field, especially before hemorrhoid surgery, doctors need to perform preoperative flushing on patients to reduce the risk of infection during surgery and ensure the smooth progress of the operation. Traditional preoperative flushing methods for hemorrhoid surgery usually involve the use of a flushing bag and a flushing tube connected thereto, with a flushing head at the end of the flushing tube for direct insertion into the patient's body for flushing.

[0003] Traditional irrigation heads usually need to be dipped in lubricating fluid before being inserted into the human body to reduce friction during insertion. This process not only increases the complexity of surgical preparation, but may also lead to uneven distribution of the lubricating fluid, thus affecting the smooth insertion of the irrigation head. Utility Model Content

[0004] The utility model provides a hemorrhoid pre-operative irrigator to solve the problem that the existing irrigating head needs to be manually dipped into lubricating liquid, resulting in complicated operation.

[0005] In order to alleviate the above technical problems, the technical solution provided by the utility model is:

[0006] A preoperative irrigator for hemorrhoid surgery, comprising a irrigating bag and a irrigating tube connected to the irrigating bag;

[0007] The end of the flushing pipe is connected to a flushing head, and the flushing head is covered with a protective shell;

[0008] A convex ring is connected to the side wall of the flushing head, and an annular bag is connected to the inner wall of the protective shell, and the annular bag is filled with lubricating liquid;

[0009] The protective shell can slide axially on the flushing head;

[0010] When the protective shell slides on the flushing head, the convex ring can press the annular bag so that the lubricating fluid in the annular bag flows out to the flushing head.

[0011] Furthermore, the annular bag is connected to a hollow belt, and a release hole is opened on the hollow belt.

[0012] Furthermore, there are multiple hollow belts, and the multiple hollow belts are evenly distributed around the annular bag.

[0013] Furthermore, the lower part of the protective shell is connected with an arc-shaped cap;

[0014] When the flushing head slides relative to the protective shell, the flushing head can push the arc-shaped cap away from the protective shell.

[0015] Furthermore, the port of the arc-shaped cap is connected to a connecting tube, the inner wall of the connecting tube is provided with a clamping ring, and the outer wall of the protective shell is provided with a clamping groove that cooperates with the clamping ring.

[0016] Furthermore, a return channel is commonly provided in the side wall of the flushing head and the flushing pipe, and two ports of the return channel are respectively provided at the liquid outlet end of the flushing head and the side wall of the flushing pipe.

[0017] Furthermore, a conical hole coaxially arranged with the return channel is provided in the return channel located at the flushing head;

[0018] A sphere is placed in the tapered hole, and an elastic block is connected between the sphere and the end wall of the tapered hole;

[0019] When the pressure of the in vivo environment increases, the flushing liquid flowing out through the flushing head flows through the return channel and pushes the ball to move relatively to the tapered hole so that the return channel is connected.

[0020] The beneficial effects of the utility model are analyzed as follows:

[0021] A preoperative irrigator for hemorrhoid surgery comprises a irrigating bag and a irrigating tube connected to the irrigating bag; a irrigating head is connected to the end of the irrigating tube, and a protective shell is mounted on the irrigating head; a convex ring is connected to the side wall of the irrigating head, and an annular capsule is connected to the inner wall of the protective shell, and the annular capsule is filled with lubricating liquid; the protective shell can slide axially on the irrigating head; when the protective shell slides on the irrigating head, the convex ring can squeeze the annular capsule so that the lubricating liquid in the annular capsule flows out to the irrigating head.

[0022] The protective shell is installed on the flushing head to protect the flushing head and prevent it from being damaged by friction and collision or scratched on the surface, so that the flushing head will not scratch the skin during subsequent use. When in use, the protective shell is manually pushed to slide relative to the flushing head to expose the flushing head. During this process, the convex ring on the flushing head is squeezed on the annular bag, so that the lubricating liquid in the annular bag flows out to the outer wall of the flushing head, so that the flushing head can be easily inserted into the human body for preoperative flushing of hemorrhoids. There is no need to dip the flushing head in lubricating liquid separately, which simplifies the preoperative flushing process of hemorrhoid surgery. The setting of the convex ring also enables the flushing head to be clamped on the human body, so that when the flushing bag is squeezed to release the flushing liquid, the pressure of the human body will not cause the flushing head to separate from the human body, and there is no need for medical staff to hold the flushing head by hand.

[0034] Example

[0035] like Figure 1-Figure 5 As shown, a preoperative irrigator for hemorrhoid surgery includes a irrigating bag 100 and a irrigating tube 110 connected to the irrigating bag 100; the end of the irrigating tube 110 is connected to a irrigating head 200, and a protective shell 300 is sleeved on the irrigating head 200; a convex ring 210 is connected to the side wall of the irrigating head 200, and an annular capsule 310 is connected to the inner wall of the protective shell 300, and the annular capsule 310 is filled with lubricating liquid; the protective shell 300 can slide axially on the irrigating head 200; when the protective shell 300 slides on the irrigating head 200, the convex ring 210 can squeeze the annular capsule 310 so that the lubricating liquid in the annular capsule 310 flows out to the irrigating head 200.

[0036] The working mechanism of the flusher provided in this embodiment is as follows:

[0037] The protective shell 300 is installed on the flushing head 200, so that the flushing head 200 is protected and prevented from being damaged by friction and collision or scratched on the surface, so that the flushing head 200 will not scratch the skin during subsequent use. During use, the protective shell 300 is manually pushed to slide relative to the flushing head 200 to expose the flushing head 200. During this process, the convex ring 210 on the flushing head 200 is squeezed on the annular capsule 310, so that the lubricating fluid in the annular capsule 310 flows out to the outer wall of the flushing head 200, so that the flushing head 200 can be easily inserted into the human body for preoperative flushing of hemorrhoids, without the need to dip the flushing head 200 in lubricating fluid separately, simplifying the preoperative flushing process of hemorrhoid surgery, and the setting of the convex ring 210 also enables the flushing head 200 to be clamped on the human body, so that when the flushing bag 100 is squeezed to release the flushing fluid, the pressure of the human body will not cause the flushing head 200 to separate from the human body, and there is no need for medical staff to hold the flushing head 200 by hand.

[0038] Regarding how to apply the lubricating liquid to the flushing head 200, specifically:

[0039] The annular bag 310 is connected to a hollow belt 320 , and a release hole 330 is opened on the hollow belt 320 .

[0040] The hollow belt 320 is connected to the annular bag 310. When the annular bag 310 is squeezed, the lubricating liquid in the annular bag 310 can flow into the hollow belt 320. As the pressure on the annular bag 310 increases, the lubricating liquid in the hollow belt 320 flows out through the release hole 330 provided therein. In addition, in order to prevent the lubricating liquid from being released prematurely from the release hole 330 due to gravity, a plastic film is also provided in the release hole 330. When the pressure on the annular bag 310 increases, the pressure causes the lubricating liquid in the release hole 330 to break through the plastic film in the hollow belt 320 and flow out.

[0041] Among the optional methods of this embodiment, the more preferred ones are:

[0042] There are multiple hollow belts 320 , and the multiple hollow belts 320 are evenly distributed on the annular bag 310 in a circumferential manner.

[0043] A plurality of hollow belts 320 are arranged in a ring shape, and the plurality of hollow belts 320 cover the outer wall of the flushing head 200 , so that the flowing lubricating liquid can be fully coated on the outer wall of the flushing head 200 .

[0044] Among the optional methods of this embodiment, the more preferred ones are:

[0045] The lower part of the protective shell 300 is connected with an arc-shaped cap 340 ; when the flushing head 200 slides relative to the protective shell 300 , the flushing head 200 can push the arc-shaped cap 340 away from the protective shell 300 .

[0046] In the initial state, the arc cap 340 is connected to the bottom end of the protective shell 300, so that the bottom of the flushing head 200 is also protected. When the protective shell 300 is pushed to slide relative to the flushing head 200, the bottom end of the flushing head 200 can apply pressure to the arc cap 340 so that the arc cap 340 is pushed away from the protective shell 300, so that the flushing head 200 can be completely exposed.

[0047] Among the optional methods of this embodiment, the more preferred ones are:

[0048] The port of the arc-shaped cap 340 is connected to a connecting tube 350 , the inner wall of the connecting tube 350 is provided with a snap ring 360 , and the outer wall of the protective shell 300 is provided with a snap groove matched with the snap ring 360 .

[0049] The connecting tube 350 is sleeved on the protective shell 300 , and when the clamping ring 360 on the inner wall of the connecting tube 350 is clamped in the groove on the outer wall of the protective shell 300 , the arc cap 340 is not easily separated from the protective shell 300 .

[0050] How to prevent excessive infusion of irrigation fluid into the intestine:

[0051] A return channel 220 is commonly provided in the side walls of the flushing head 200 and the flushing tube 110 , and two ports of the return channel 220 are respectively provided at the liquid outlet end of the flushing head 200 and the side wall of the flushing tube 110 .

[0052] The setting of the return channel 220 ensures that when the flushing liquid is blocked during infusion into the intestine, if the flushing head 200 continues to infuse flushing liquid into the intestine, the pressure in the intestine causes excess flushing liquid to flow out of the intestine through the return channel 220. On the one hand, it prevents the flushing head 200 from being detached due to pressure and causing the flushing liquid to spill out, and on the other hand, it prevents excessive infusion of flushing liquid and causes discomfort to the human body.

[0053] Among the optional methods of this embodiment, the more preferred ones are:

[0054] A conical hole 230 coaxially arranged with the return channel 220 is provided in the return channel 220 located at the flushing head 200; a sphere 240 is placed in the conical hole 230, and an elastic block 250 is connected between the sphere 240 and the end wall of the conical hole 230; when the internal body environmental pressure increases, the flushing liquid flowing out through the flushing head 200 flows through the return channel 220 and pushes the sphere 240 to move relative to the conical hole 230 so that the return channel 220 is connected.

[0055] In order to prevent the outflow of flushing liquid when the pressure in the intestine has not increased, a sphere 240 is further provided in the return channel 220. A conical hole 230 cooperating with the sphere 240 is opened in the return channel 220. In the initial state, the elastic block 250 is not deformed. At this time, the elastic block 250 applies thrust to the sphere 240, so that the sphere 240 blocks the small opening of the conical hole 230. When the pressure in the intestine increases, the excess flushing liquid is poured into the return channel 220 under the action of pressure. At this time, the pressurized flushing liquid pushes the sphere 240 to flow toward the large opening of the conical hole 230, so that the flushing liquid flows through the small opening of the conical hole 230 and passes through the conical hole 230. At this time, the flushing liquid can flow out through the return channel 220, so that the pressure in the human intestine will not increase excessively.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of each embodiment of the utility model.
