Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a balloon-assisted compression device for colonoscopy. Background Technology

[0002] With the improvement of people's living standards, people regularly undergo internal medicine checkups. Colonoscopy is a type of gastrointestinal examination. Colonoscopy involves inserting a colonoscope through the anus into the ileocecal junction to observe colonic lesions from the mucosal side. Clinically, difficulties in inserting the colonoscope often arise due to adhesions after abdominal surgery, or because the patient's intestines are long, tortuous, or have large bends. Currently, in addition to changing the patient's position, medical staff often press on the abdomen (commonly known as "pressing the endoscope") to change the position of the intestines, reduce bends, and decrease resistance, making it easier for the endoscope to pass and improving the success rate. This is especially true in areas like the sigmoid colon and transverse colon, where bends and loops are prone to form. Pressing the abdomen helps reduce these occurrences. Furthermore, during colonoscopy, pressing the abdomen can control the distribution of gas within the intestinal lumen, reducing abdominal distension and pain, and improving patient comfort. However, this requires close cooperation between medical staff and certain pressing techniques, which is time-consuming and labor-intensive, limiting the development of single-person colonoscopy techniques and presenting technical challenges.

[0003] Currently, a search reveals that Chinese utility model patent CN202950714U discloses a novel multi-site inflatable abdominal compression band for colonoscopy, comprising: 1. an air bladder, 2. a switch, 3. a hollow air bladder connecting tube, 4. a detachable connection point between the inflatable air bladder or air pump and the main air bladder connecting tube, 5. an inflatable air bladder switch, 6. an inflatable air bladder, 7. strong Velcro, 8. a fixing connector, 9. a fixing strap, 10. a fixing strap, 11. a fixing connector socket, and 12. a pressure gauge. While this patent allows for abdominal compression, it still has the following technical drawbacks:

[0004] On the one hand, a switch is set on each airbag connecting tube, and the opening and closing of different airbag airways is achieved by operating the switch. However, since the switches are scattered and the corresponding switch needs to be found along the connecting tube from one end of the airbag when operating the switch, the operation is relatively complicated. It is also difficult to find the corresponding switch quickly when the airbag connecting tube is tangled.

[0005] On the other hand, inflating the airbag using a balloon requires repeated pressing, which increases the workload of medical staff and is not convenient.

[0006] To address the inconvenience of using the abdominal compression belt, which requires locating the corresponding switch and squeezing the balloon for inflation, the key to solving these technical problems lies in developing a more practical and efficient balloon-assisted compression device for colonoscopy. Summary of the Invention

[0007] In view of the many defects and deficiencies existing in the above-mentioned background technology, this utility model has made improvements and innovations, with the aim of providing a balloon auxiliary pressing device for colonoscopy, which is easy to operate and opens and closes the balloon air passage by pushing the push knob to squeeze the balloon tubing.

[0008] Another objective of this invention is to enable the air pump to inflate and deflate the airbag by controlling the three-way valve during the air supply process, through the setting of a three-way valve.

[0009] Another objective of this invention is to facilitate operators to quickly select the appropriate push knobs to inflate or deflate the airbag by setting corresponding labels on the control seat and the fixed plate.

[0010] To solve the above problems and achieve the objectives of the invention, this utility model provides a balloon-assisted compression device for colonoscopy, which is implemented by adopting the following design mechanism and the following technical solution:

[0011] A balloon-assisted compression device for colonoscopy includes an air pump (1) and a compression device (2), wherein the compression device (2) includes:

[0012] The waist belt (21) is made of soft material. It has Velcro at both ends and a fixing plate (211) in the middle. The fixing plate (211) has Velcro on one side and several airbags (212) on the other side. The airbags (212) are connected to one end of the bundle tube (22).

[0013] The control handle (23) is connected to the other end of the bundle tube (22) and connected to the connecting tube (244) through the converter (232). The control handle (23) can be used to control the opening and closing of the air passage of different airbags (212).

[0015] Preferably, the control handle (23) includes:

[0016] The control component (231) includes several sets of control seats (2311), push knobs (2312), and limiting holes (2313). The push knobs (2312) are set in the corresponding rectangular slots on the control seats (2311) and are connected to the sliding holes on the sidewalls of the rectangular slots through connecting shafts, and can slide along the sliding holes in the rectangular slots. The pipelines in the bundle tube (22) pass through the push knobs (2312) from below and through the limiting holes (2313) to the inside of the control seats (2311).

[0017] The adapter (232) is a nine-hole to one-hole connector. One end is connected to the bundle tube (22) that passes through the limiting hole (2313), and the other end is connected to the connecting tube (244).

[0018] The handheld part (233) is threadedly connected to the control assembly (231);

[0019] Among them, the sliding hole has a structure with one end high and the other end low. When the pusher (2312) moves from high to low, it squeezes the pipeline, causing the air passage of the airbag (212) to close.

[0020] Preferably, the bundle tube (22) is a number of air tubes enclosed by the outer shell, and the air tubes correspond to the airbag body (212).

[0021] Preferably, the three-way valve (24) includes:

[0022] A three-way pipe (241) is connected at both ends to a connecting pipe (244) and a vent pipe (11), and a vent valve (243) is installed in the middle.

[0023] Control switch (242), which is sealed to the three-way pipe (241), is used to control the switching of the gas path;

[0024] Air valve (243) is used to adjust the opening and size of the air outlet.

[0025] Preferably, the control seat (2311) has a numbered label next to the rectangular slot, and the number of the labels is the same as the number of airbag bodies (212).

[0026] Preferably, the airbag body (212) has nine designs, corresponding to the right hypochondrium, epigastric region, left hypochondrium, right lumbar region, umbilical region, left lumbar region, right iliac region, hypogastric region, and left iliac region, respectively. The fixing plate (211) and the airbag body (212) are respectively marked with numbers, which correspond to the control seat (2311).

[0027] Preferably, the surface of the pusher (2312) is provided with "stripes, rhombuses or dots" to increase friction.

[0028] Preferably, the sidewall of the handheld part (233) is provided with several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns to increase friction.

[0029] Preferably, the pressing device (2) further includes: a pad (3), the end face of the pad (3) is provided with Velcro, which is connected to the waist belt (21) through the Velcro, and the connecting end of the pad (3) is provided with a fixing strap, which is connected to the hospital bed through the fixing strap;

[0030] The fixing strap is equipped with buckles for easy installation and adjustment.

[0031] The working principle is as follows: In the above-described balloon-assisted compression device for colonoscopy, the air pump 1 supplies air. The control switch 242 connects the connecting tube 244 and the ventilation tube 11. Medical personnel observe the length of the intubation, determine the position of the endoscope tip, and identify the compression point. Based on the markings on the fixing plate 211, they push the corresponding knob 2312 to open the air passage, inflating the balloon 212. After the balloon 212 expands, the control switch 242 releases excess air through the air valve 243. Pushing the knob 2312 closes the air passage, causing the balloon 212 to bulge and compress the patient's intestines, effectively reducing intestinal tortuosity and facilitating endoscope insertion. Once the endoscope tip passes this area, pushing the knob 2312 opens the air passage, and the control switch 242 releases the air from the balloon 212. If further insertion becomes difficult, the above operation is repeated until the colonoscopy is completed.

[0032] In summary, the beneficial effects of this utility model compared with the prior art are as follows:

[0033] 1. Because this utility model is equipped with a control seat, during use, by pushing the push knob, the push knob is squeezed to compress the pipeline inside the bundle tube, thereby realizing separate control of the opening and closing of the air passage of the airbag, making the operation more convenient.

[0034] 2. This utility model is equipped with a three-way valve, which allows for the replacement of the air path and prevents damage to the airbag due to excessive air pressure during the inflation process using an air pump.

[0035] 3. Because this utility model is equipped with a handheld part, medical personnel can operate the control components by holding the handheld part during operation. The handheld part provides a force-bearing area, which is convenient for operation. In addition, the handheld part is sleeved on the outside of the conversion head to prevent the bundle tube from falling off due to accidental contact during operation.

[0036] 4. This utility model improves work efficiency by setting corresponding labels on the fixed plate and control base, which makes it easy for operators to quickly find the push knob corresponding to the required inflation / deflation airbag.

[0037] 5. By setting up a pad, this utility model provides overall support to the patient's abdomen when pressing on the patient, so that the air bladder can play a better role when inflating and pressing on the intestinal tract. Attached Figure Description

[0053] To make the technical means, inventive features, and achieved objectives and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] Example 1

[0055] like Figures 1 to 11 The illustrated balloon-assisted compression device for colonoscopy includes an air pump 1 and a compression device 2, wherein the compression device 2 includes:

[0056] The waist belt 21 is made of soft material. It has Velcro at both ends and a fixing plate 211 in the middle. The fixing plate 211 has Velcro on one side and several airbags 212 on the other side. The airbags 212 are connected to one end of the bundle tube 22.

[0057] The control handle 23 is connected to the other end of the bundle tube 22 and is connected to the connecting tube 244 through the adapter 232. The control handle 23 can be used to control the opening and closing of the air passages of different airbags 212.

[0058] Three-way valve 24, one end of which is connected to connecting pipe 244, and the other end is connected to air pump 1 through vent pipe 11. Excess gas is released through air valve 243 in the middle.

[0059] Before using one of the balloon-assisted compression devices for colonoscopy, as described above, medical personnel must first assemble it. During assembly:

[0060] Medical personnel first pass one end of the bundle tube 22 through the fixing plate 211 and connect it to the airbag body 212, and pass the other end through the rectangular slots between the push knob 2312 and the control seat 2311, as follows. Figure 5 As shown, the labels on the fixing plates 211 connected to both ends of the bundle tube 22 correspond to the labels next to the push knob 2312. After passing the bundle tube 22 through the limiting hole 2313, connect it to one end of the converter head 232. The other end of the converter head 232 is connected to the connecting tube 244. Then connect the handheld part 233 to the control assembly 231. Use the three-way valve 24 to connect the connecting tube 244 and one end of the air pipe 11. The other end of the air pipe 11 is connected to the air pump. Figure 4 As shown, the assembly of this utility model is now complete.

[0061] When in use, medical personnel secure the waist belt 21 to the patient's abdomen using Velcro, ensuring the fixing plate 211 is aligned with the patient's intestines. Figure 1 As shown, the routine colonoscopy procedure begins. If difficulty in inserting the endoscope is encountered, the medical staff determines the position of the endoscope tip based on the insertion length. Based on the position of the endoscope tip, they identify the corresponding balloon 212. Then, according to the markings on the fixing plate 211, they push the corresponding knob 2312 to open the trachea in the bundle tube 22. Under the action of the air pump 1, the balloon 212 is inflated. After inflation, pushing the knob 2312 compresses the trachea, closing the airway. Then, the control switch 242 is operated to connect the ventilation tube 11 and the air valve 243, allowing gas to be released from one end of the air valve 243. Figure 8 As shown, at this time, the balloon 212 presses against the intestinal tract, changing its position and reducing bends, making it easier for the colonoscope to pass through. After the endoscope tip has passed through, the medical staff operates the control switch 242 to connect the connecting tube 244 and the air valve 243, pushes the push knob 2312 to open the tracheal airway, and under the action of the waist belt 21, the balloon 212 is compressed, and the gas inside the balloon 212 is discharged from the air valve 243. Then, the push knob 2312 is pushed to compress the trachea to close the airway, and the control switch 242 is adjusted to discharge gas from the air valve 243. Figure 9 As shown. If you encounter difficulty getting into the shot again, repeat the above steps to complete the shot entry.

[0062] After use, medical staff removed the belt 21 and placed it in a fixed position for the next use.

[0063] Example 2

[0064] This embodiment 2 is the same as embodiment 1, except that the handheld part 233 has several ring-shaped or granular protective protrusions or strip-shaped anti-slip patterns on its side wall to increase friction and prevent the handheld part 233 from slipping during the inspection process, which would make it difficult to push the push knob 2312.

[0065] Example 3

[0066] This embodiment 3 is the same as embodiment 1 and embodiment 2, the only difference being that, Figure 10 As shown, the fixing plate 211 has a Velcro strap on one end face and the pad 3 has a Velcro strap on the end face. The pad 3 is connected and fixed to the waist belt 21 by the Velcro strap. The connecting end of the pad 3 is provided with a fixing strap and a buckle is provided on the fixing strap.

[0067] In this invention, the fixing strap is used to connect the pad 3 to the hospital bed, and the buckle is used for quick installation, disassembly and adjustment of the fixing strap length during the connection process, so that the pad can better support the patient's abdomen.

[0068] During use, when the patient is heavy, the waist belt 21 alone is not effective for fixation. When the patient is in a lateral position, the abdomen is in a drooping state, and the airbag 212 cannot be accurately positioned to the patient's intestines. Therefore, the pad 3 needs to be used to support and lift the patient's abdomen. Medical staff can fix the fixation straps to the bed side panel, such as... Figure 11 As shown, adjust the length of the fixing belt until the pad 3 compresses and supports the patient's abdomen, so that the air bladder 212 corresponds to the position of the patient's intestinal tract, and then perform the colonoscopy.

[0069] In this utility model, the connection is either a fixed connection or a detachable connection. The fixed connection is either a welded connection or a directly machined integral structure, while the detachable connection is either an internal or external threaded connection, a snap-fit ​​connection, or a plug-in structure connection.

[0070] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
