Description

Technical Field

[0001] This invention relates to the field of enema imaging technology, specifically to an enema imaging device for radiology. Background Technology

[0002] Enema imaging involves injecting a contrast agent into the patient's intestines, followed by examination of the intestines using X-ray or other imaging equipment.

[0003] Barium enema is commonly used for colonic examinations. Before the examination, the barium solution needs to be prepared by mixing 200-250g of barium sulfate, an appropriate amount of gelatin, and 800-1000ml of water. The barium solution is poured into the enema bag and suspended on a support frame, with the bag no more than 90cm above the table. The end of the rectal tube is then coated with lubricant and inserted into the patient's rectum until it reaches the cecum or part of the terminal ileum, usually about 10cm. The barium solution is then slowly injected into the patient's intestines while an X-ray probe is used to irradiate the intestines and create an image. In some patients, due to the stimulation of the intestines by the rectal tube and the barium solution, some barium solution may leak out of the anus. In such cases, an inflatable balloon should be placed outside the rectal tube, and the balloon should be inflated promptly if leakage is detected to reduce the possibility of barium solution leakage.

[0004] However, in practice, because it is unclear whether the injection of barium solution and the insertion of the rectal tube will stimulate the patient to defecate, the balloon is usually not inflated to minimize damage to the patient's sphincter and intestinal wall. Instead, the balloon is inflated with a syringe only when the patient leaks fluid. This procedure causes some barium solution to leak out and stain the sheets, causing discomfort to the patient's skin. Medical staff also face the possibility of being contaminated by the sprayed fluid during inflation. Therefore, we propose a radiology enema imaging device. Summary of the Invention

[0005] The purpose of this invention is to provide an enema imaging device for radiology to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a radiology enema imaging device, comprising:

[0007] An anal tube is inserted into the patient's anus. One side of the anal tube is connected to an enema bag via an IV line. The enema bag is placed on a support frame to create a fluid level difference between the enema bag and the anal tube.

[0008] The blocking mechanism is installed on the outside of the anal canal and is inserted into the patient's anus along with the anal canal;

[0009] The control mechanism is installed on the outside of the anal canal. The control mechanism is inserted into the patient's internal and external sphincter muscles along with the anal canal. When the patient feels the urge to defecate, the control mechanism inflates the blocking mechanism, causing the blocking mechanism to block the barium fluid in the intestine.

[0010] Preferably, the blocking mechanism includes a cannula installed on the outside of the anal canal, with an air bladder fixedly connected to the outside of the cannula, and the air bladder communicating with the outside through a trachea.

[0011] Preferably, the airbag is fitted to the outside of the sleeve, and lubricant is filled between the airbag and the sleeve.

[0012] Preferably, the airbag is divided into an expansion section one, a sliding section and an expansion section two, with lubricant located between the expansion section two and the sleeve.

[0013] Preferably, the control mechanism includes a fixed sleeve installed on the outside of the sleeve. The fixed sleeve is a silicone sleeve. The fixed sleeve has an inner cavity corresponding to the internal sphincter. One side of the inner cavity is an outer cavity, which corresponds to the external sphincter. An installation frame is inserted into the fixed sleeve. The installation frame is provided with spring piece one, spring piece two, metal piece one, and metal piece two. Spring piece one and metal piece one are located in the inner cavity, and spring piece two and metal piece two are located in the outer cavity.

[0014] Preferably, an air pump is fixedly connected to one side of the support frame, and the air pump is connected to the mounting frame by a wire, with the air nozzle of the air pump connected to an air pipe.

[0015] Preferably, the support frame is provided with an adjustment mechanism for adjusting the height of the enema tube. The adjustment mechanism works with the control mechanism to adjust the height of the enema tube. The adjustment mechanism includes a motor fixedly connected to the mounting frame. A sliding groove is opened on the surface of the support frame. A sliding frame is inserted into the sliding groove on the surface of the support frame. The enema tube is placed in the sliding frame. A screw is rotatably connected inside the mounting frame. The sliding frame is threadedly connected to the screw. A gear one is fixedly connected to the outside of the screw. A gear two is fixedly connected to the free end of the motor output shaft. Gear one and gear two mesh.

[0016] Preferably, the lowest end of the chute is higher than the patient's position, and a squeeze switch is fixedly connected to the bottom end of the support frame. The squeeze switch is electrically connected to the air pump and the motor respectively.

[0017] Preferably, the cannula is a silicone tube, and the side of the cannula near the end of the anal canal is tapered, with an interference fit between the cannula and the anal canal.

[0018] Preferably, a pressure sensor is provided between the sliding frame and the enema tube, the pressure sensor is fixedly connected to the sliding frame, a guide rail is fixedly connected to one side of the support frame, an iron block is fixedly connected to the surface of the guide rail, an electromagnet is slidably connected to the surface of the guide rail, and the infusion tube is located between the iron block and the electromagnet.

[0019] This invention has at least the following beneficial effects:

[0020] This invention uses a blocking mechanism and anal tube to block the patient's anus. A control mechanism prevents the blocking mechanism from activating when the patient does not feel the urge to defecate. When the patient experiences the urge, the blocking mechanism is activated to block the anus. In contrast, existing technologies often fail to inflate the balloon until leakage occurs, as it's unclear whether the barium injection and anal tube insertion will stimulate defecation. This leads to some barium leakage staining the sheets and causing discomfort to the patient's skin. Medical staff may also be contaminated by the spray during inflation. This invention prevents the blocking mechanism from blocking the anus when the patient does not feel the urge, reducing the possibility of damage to the anal mucosa and maintaining patient comfort. When the patient feels the urge, the blocking mechanism automatically inflates, promptly blocking the anus and preventing barium splashes on medical staff, reducing bed sheet contamination, and minimizing patient discomfort.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-15 The present invention provides a technical solution:

[0039] Example 1,

[0040] An enema imaging device for radiology, comprising:

[0041] An anal tube is inserted into the patient's anus. One side of the anal tube is connected to an enema container via an IV line. The enema container is placed on a support frame to create a liquid level difference between it and the anal tube. The enema container usually contains a pre-mixed barium solution to facilitate direct enema examination of the patient.

[0042] The blocking mechanism is installed on the outside of the anal tube and is inserted into the patient's anus along with the anal tube. When the patient feels the urge to defecate, the blocking mechanism can easily block the anus, reducing the possibility of barium fluid leakage from the patient's body, reducing the staining of the bed sheets, and reducing the discomfort on the patient's skin after the barium fluid leakage.

[0043] The control mechanism is installed on the outside of the anal canal. Inserted along with the anal canal, it reaches the patient's internal and external anal sphincter muscles. When the patient experiences the urge to defecate, the control mechanism inflates the blocking mechanism, causing it to block barium fluid within the intestines. The control mechanism can control the blocking mechanism's operation on the anus based on the compression state of the patient's internal and external anal sphincter muscles.

[0044] The internal sphincter is not actively regulated by the patient, so it relaxes when the urge to defecate arises. The external sphincter is actively controlled by the patient, so it relaxes and tightens when the urge to defecate arises. At this time, the control mechanism will control the inflation of the occlusion mechanism. When the patient does not feel the urge to defecate, both the internal and external sphincters are in a tightened state, and the control mechanism will not control the inflation of the occlusion mechanism.

[0045] The blocking mechanism includes a cannula installed on the outside of the anal canal, with an airbag fixedly connected to the outside of the cannula. The airbag is connected to the outside through a trachea and can be inflated by an external air pump, thereby reducing the possibility of barium liquid sprayed by medical staff during inflation splashing onto the medical staff.

[0046] The control mechanism includes a fixed sleeve installed on the outside of the sleeve. The fixed sleeve is a silicone sleeve and is fixedly connected to the sleeve. The fixed sleeve has an inner cavity corresponding to the internal sphincter. The surfaces of the fixed sleeve in the inner and outer cavities are thin films, which can facilitate the clamping of the internal and external sphincter with spring 1 or spring 2. This allows spring 1 and spring 2 to contact metal plate 1 and metal plate 2 respectively under the clamping of the internal and external sphincter, thereby controlling the inflation of the air pump. One side of the inner cavity is the outer cavity, which corresponds to the external sphincter. A mounting bracket is inserted inside the fixed sleeve. The mounting bracket has spring 1, spring 2, metal plate 1, and metal plate 2. Spring 1 and metal plate 1 are located in the inner cavity, and spring 2 and metal plate 2 are located in the outer cavity.

[0047] An air pump is fixedly connected to one side of the support frame. The air pump is connected to the mounting frame via a wire, and the air nozzle of the air pump is connected to an air pipe.

[0048] After inserting the mounting bracket into the fixing sleeve, the cannula is then slipped over the outside of the anal cannula, and the fixing sleeve is slipped over the outside of the cannula. At this point, the anal cannula, cannula, balloon, and fixing sleeve are inserted into the patient's anus. When the outside of the fixing sleeve is pressed firmly against the anus, the internal sphincter is located on the outside of the internal lumen, the external sphincter is located on the outside of the external lumen, and the balloon is located between the internal sphincter and the rectum. At this point, barium solution is injected into the patient's colon through the anal cannula. After the ileum is stimulated by the barium solution, if both the internal and external sphincter muscles are in a tightened state, then spring one and metal plate one are in close contact, spring two and metal plate two are in close contact, spring one and metal plate one are energized, and spring two and metal plate two... When the power is on, the air pump is not operating, and the patient can control it independently, placing them in a relatively comfortable state. When the patient's internal sphincter is not under voluntary control and they experience the urge to defecate, the internal sphincter relaxes, the spring and metal plate disengage, the air pump is powered on, and the air pump inflates the cuff through the trachea. When the cuff is full of gas and reaches its maximum pressure, the air pump detects the pressure and stops inflating. At this point, the rectum and internal sphincter are sealed, preventing the barium solution from being expelled due to the urge to defecate, thus facilitating the infusion of barium solution. After the barium solution infusion is complete, the medical staff manually turn off the air pump, the cuff deflates and releases, and the rectal tube is removed, allowing the barium solution to drain slowly.

[0049] According to the above embodiments, Embodiment Two

[0050] The air bladder fits against the outside of the cannula, and the space between the air bladder and the cannula is filled with lubricating fluid. The lubricating fluid provides lubrication for the insertion of the anal tube and air bladder into the anus, facilitating the insertion of the anal tube, air bladder, and fixation sleeve.

[0051] The airbag is divided into an expansion section one, a sliding section and an expansion section two, with lubricating fluid located between the expansion section two and the sleeve.

[0052] The cannula is made of silicone tubing. The side of the cannula near the end of the anal canal is tapered. The tapering design facilitates the insertion of the cannula and allows the anal canal to be inserted from the non-tapered side of the cannula, reducing the possibility of the anal canal and the cannula falling off relative to each other. It also facilitates the relative fixation between the anal canal and the cannula, and the cannula and the anal canal have an interference fit.

[0053] When assembling the cannula and anal tube, simply insert the anal tube into the non-constricted end of the cannula. The constricted end of the cannula will be squeezed by the anal tube, facilitating the relative assembly of the anal tube and the cannula. When the anal tube, cannula, and balloon are inserted into the patient's anus, the second expansion part of the balloon directly contacts the patient's skin. The patient's body squeezes the second expansion part, squeezing out the lubricating fluid located between the first expansion part and the cannula, facilitating lubrication on the outside of the anal tube. Simultaneously, during insertion, the second expansion part does not initially move relative to the patient's body; the sliding part slides on the surface of the cannula, pushing out the first expansion part. The pushed-out expansion part carries out the lubricating fluid, further enhancing lubrication and making the insertion of the cannula and balloon easier. Furthermore, when the first and second expansion parts are inflated, the height of the first expansion part is lower than that of the second expansion part, forming two layers of barrier between the patient's internal sphincter and rectum. This better prevents barium solution from entering the rectum and ileum, facilitating barium solution infusion.

[0054] According to the above embodiments, in Embodiment 3,

[0055] The support frame is equipped with an adjustment mechanism for adjusting the height of the enema bag. The adjustment mechanism works in conjunction with the control mechanism to adjust the height of the enema bag. When the patient is receiving an enema, if the barium solution is less irritating to the patient, it can be injected at a faster speed. If the solution is more irritating to the patient and the patient feels the urge to defecate, the injection speed needs to be slowed down. The adjustment mechanism includes a motor fixedly connected to the mounting frame. The surface of the support frame has a sliding groove, and a sliding frame is inserted into the groove. The groove limits the sliding frame. The sliding frame is slidably connected to the mounting frame. The enema bag is placed in the sliding frame. A screw is rotatably connected inside the mounting frame. The sliding frame is threadedly connected to the screw. Gear 1 is fixedly connected to the outside of the screw. Gear 2 is fixedly connected to the free end of the motor output shaft. Gear 1 and Gear 2 mesh.

[0056] The lowest point of the chute is higher than the patient's position. The support frame is fixedly connected to the squeeze switch at the bottom of the chute. The squeeze switch is electrically connected to the air pump and the motor respectively.

[0057] When the patient experiences the urge to defecate, the first spring and the first metal plate separate, while the second spring and the second metal plate remain pressed together. The motor is activated, driving the first gear to rotate, which in turn drives the second gear to rotate, which in turn drives the screw to rotate. Under the limiting action of the sliding groove, the screw drives the sliding frame to descend, which in turn lowers the height of the enema tube until the first spring and the first metal plate re-adhere. If the patient still experiences the urge to defecate, the sliding frame squeezes the switch, stopping the motor. Simultaneously, the air pump switch is turned on, and the air pump begins to inflate the cuff, thereby blocking the outer side of the patient's internal sphincter and reducing the possibility of barium leakage. By first lowering the height of the enema tube, the rate of barium infusion is reduced, thus reducing the patient's urge to defecate. If the urge to defecate cannot be eliminated, the cuff is inflated again, reducing damage to the intestinal wall and minimizing patient discomfort.

[0058] According to the above embodiments, Embodiment 4,

[0059] A pressure sensor is installed between the sliding frame and the enema tube, and the pressure sensor is fixedly connected to the sliding frame. A guide rail is fixedly connected to one side of the support frame, and an iron block is fixedly connected to the surface of the guide rail. An electromagnet is slidably connected to the surface of the guide rail. The infusion tube is located between the iron block and the electromagnet. When the barium solution in the enema tube is infused into the patient's ascending colon, in order to reduce the excessive inflow of barium solution into the patient's ileum and reduce the impact of barium solution on the patient, when the barium solution in the enema tube drops to a level sufficient to infuse the patient's colon, the pressure on the pressure sensor decreases to a critical value. At this time, the pressure sensor controls the electromagnet to be energized, and the electromagnet attracts the iron block. The electromagnet slides on the track, and the electromagnet and the iron block attract each other, thereby directly clamping the infusion tube and stopping the infusion of the remaining barium solution. If medical staff still need to infuse barium solution, they only need to loosen the electromagnet and the iron block, reducing the possibility of excessive barium solution infusion into the ileum, reducing the impact on the patient, and facilitating the patient's subsequent excretion of barium solution.
