Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a colonoscopy assisting device. Background Art

[0002] When performing colonoscopy in hospitals, air or water is pumped into the intestines. During this process, the body is squeezed by the gas in the body, and the abdominal pressure increases. Especially when the anus contracts, the abdominal pressure increases, and the feces and water in the intestines are squeezed and easily sprayed out of the anus, causing pollution. In addition, once the feces and water are sprayed out, the impact force on the colonoscope is greatly increased, and the colonoscope is easily squeezed and dislocated. For this reason, people have designed colonoscopy assistive devices.

[0003] The existing colonoscopy assist device uses a conical tube to open the anus to prevent it from shrinking, and collects fecal water through a water collection bag to prevent it from spraying out and causing pollution. Although this structure effectively solves the above-mentioned problems, when the amount of fecal water is large, it is easy to be squeezed at the mouth of the water accumulation belt, causing part of the fecal water to be discharged through the through hole, causing pollution. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, the purpose of the present invention is to provide a colonoscopy assisting device to solve the above-mentioned technical problems.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution provided by the present invention is as follows:

[0007] Preferably, there are two blocks, which are located on both sides of the water collecting bag; and the first fixing belt and the second fixing belt are located on both sides of the water collecting bag.

[0008] Preferably, the elastic telescopic body is arc-shaped, with its opening facing away from the water collecting bag.

[0009] Preferably, a cover curtain for sealing the through hole is provided on the base, the cover curtain is made of rubber or silicone, double-sided tape is provided on one end close to the water collecting bag and on both sides, and the end away from the water collecting bag is connected to the base.

[0010] Preferably, the first fixing belt and the second fixing belt are plastic belts.

[0011] Preferably, the blocking portion is a barb or a blocking block.

[0012] Preferably, the elastic expansion body is a corrugated structure arranged on both sides of the base.

[0013] Preferably, the water collecting bag is made of rubber or silicone.

[0014] When the colonoscope assisting device provided by the present invention is in use, the conical tube can be inserted along the anus, and the through hole is located above the water collecting bag during insertion. Then, the base is fixed with the first fixing belt and the second fixing belt, and the colonoscope can be inserted along the conical tube through the through hole; before fixing the base, the first fixing belt and the second fixing belt are passed around the corresponding binding belt, and after the base is fixed, the first fixing belt and the second fixing belt are pulled to cause the elastic telescopic body to contract, and then the blocking part is pressed against the block, and the cavity contracts accordingly. The gas in the cavity is squeezed and partially enters the water collecting bag, opening the inlet of the water collecting bag, which is conducive to squeezing feces into the water collecting bag; when feces are sprayed out, feces are collected in the water collecting bag. When the amount of feces is large, the weight of the water collecting bag increases, compressing the base so that the block can move relative to the blocking part, and the first fixing belt and the second fixing belt are separated from the corresponding block restriction. The elastic telescopic body stretches and drives the cavity to stretch, generating negative pressure, so that the feces are quickly discharged into the cavity, preventing the feces from being instantly accumulated at the mouth of the water collecting bag and spraying out along the through hole.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] Example 1, see Figure 1 and Figure 2 , the present invention provides a colonoscopy assist device, including a base 1, the base material of which can be hard rubber or hard silicone, a first strap 2 is fixed to one side of the base, and a second strap 3 is fixed to the other side of the base. During production, side ears can be provided on both sides of the base, and the first strap and the second strap are fixed on the corresponding side ears, or the straps can be directly integrated with the base or fixed to the base by existing methods such as bonding and riveting, which are not specifically limited here; a conical tube 1-1 is provided on the base, and during production, the end of the conical tube with a larger diameter is connected to the base, and the conical tube and the base are preferably formed as one piece; a water collecting bag 4 is provided on the side of the base facing away from the conical tube, and the water collecting bag can be a plastic bag, preferably made of rubber or silicone, and the conical tube is connected to the interior of the water collecting bag; a through hole 1-2 connected to the interior of the conical tube is provided on the base, and a cavity 1-3 is provided on the end of the base away from the conical tube, and the conical tube and the through hole are respectively connected to the cavity , elastic retractable bodies are provided on both sides of the base corresponding to the positions of the chamber. In this embodiment, the elastic retractable bodies are corrugated structures 1-4 provided on both sides of the base. The corrugated structure can be directly integrally formed with the base or provided separately. Specific limitations are made here as long as the function of shrinking when squeezed and rebounding when released can be achieved; the first strap and the second strap are located at one end of the base close to the conical tube, and the end of the base away from the conical tube is provided with a first fixing strap 21 and a second fixing strap 22. The first fixing strap and the second fixing strap are preferably plastic straps, such as made of cable tie material: one end of the first fixing strap and one end of the second fixing strap are both connected to the base, and one end of the first fixing strap and the other end of the second fixing strap are both provided with a blocking part, wherein the blocking part can be a barb 23 or a blocking block. In this embodiment, a barb is preferably used, and the barb angle is preferably around 75°; the end of the base away from the conical tube is provided with a blocking block 1-5 that cooperates with the blocking part.

[0021] When the above-mentioned colonoscopy auxiliary device is in use, the conical tube can be inserted along the anus, and the through hole is located above the water collecting bag during insertion. Then, the base is fixed with the first fixing belt and the second fixing belt, and the colonoscope can be inserted along the conical tube through the through hole; before fixing the base, the first fixing belt and the second fixing belt are passed around the corresponding binding belt. After the base is fixed, the first fixing belt and the second fixing belt are pulled to cause the elastic telescopic body to contract, and then the blocking part is pressed against the block, and the chamber contracts accordingly. The gas in the chamber is squeezed and partially enters the water collecting bag, which opens the inlet of the water collecting bag, which is conducive to squeezing feces into the water collecting bag; when feces are sprayed out, feces are collected in the water collecting bag. When the amount of feces is large, the weight of the water collecting bag increases, compressing the base so that the block can move relative to the blocking part, and the first fixing belt and the second fixing belt are separated from the corresponding block restriction. The elastic telescopic body stretches and drives the chamber to stretch, generating negative pressure, so that feces are quickly discharged into the chamber, preventing feces from instantly accumulating at the mouth of the water collecting bag and spraying out along the through hole.

[0022] In actual production, the first strap and the second strap can be provided with mutually cooperating buckles for easy fixation, and a Japanese buckle can be provided on the second strap to adjust the tightness of the strap. This is well known to those skilled in the art and will not be described in detail here.

[0023] In one embodiment, there are two stoppers located on both sides of the water collection bag; the first fixing belt and the second fixing belt are located on both sides of the water collection bag. In this way, when the water collection bag is squeezed against the base, the stoppers on both sides are more likely to move simultaneously with the squeezing of the base.

[0024] In one embodiment, the elastic telescopic body is arc-shaped, with its opening facing away from the water collecting bag, so that when the water collecting bag squeezes the base, the block can easily move away from the blocking body and rotate slightly, making it easier to separate the blocking body and the block.

[0025] Example 2, see Figure 3 The structure of embodiment 2 is roughly the same as that of embodiment 1, except that: a cover curtain 5 for blocking the through hole is provided on the base body. The cover curtain is made of rubber or silicone, and double-sided tape is provided on one end close to the water collection bag and on both sides. The end away from the water collection bag is connected to the base body, and can also be provided as a whole during production. When this structure is in use, after the colonoscope is inserted through the through hole along the conical tube, the cover curtain can be fixed to the base body with double-sided tape to block the through hole. In this way, after the cavity shrinks, more internal gas enters the water collection bag, making it easier to open the opening of the water collection bag; the negative pressure generated during the recovery of the cavity is greater, which is more conducive to preventing fecal water from accumulating at the mouth of the water collection bag.

[0026] The above-described embodiments merely illustrate the implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
