Abstract
Description
Technical Field
[0001] The invention relates to the field of anal enema blocking, in particular to an anal elastic blocking enema. Background Art
[0002] During the operation, the patient will be anesthetized, so that the anus will relax. If there is feces, it will flow out and cause pollution, which is not conducive to the operation. Therefore, enema will be performed before the operation to ensure the cleanliness of the intestine. The current enema is injected into the rectum through a syringe-like injection mechanism and a catheter. Because the catheter is not very thick and the anus is elastic, it is particularly easy to leak after the drug is injected, contaminating the bed sheets and increasing the workload of medical staff. At the same time, the leaked drug reduces the total amount of drug injected and the effect is not good. Therefore, how to block the anus during enema to avoid leakage is an urgent problem that technicians in this field need to solve. Summary of the invention
[0003] The object of the present invention is to provide an anal elastic blocking enema to solve the problems raised in the above background technology.
[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an elastic anal plugging enema, comprising an injection mechanism for pushing and injecting a medicinal solution and a catheter connected to the injection mechanism, the injection mechanism being used for pushing and injecting the medicinal solution, a plugging airbag which can be expanded after being inflated is sleeved on the injection mechanism, and the plugging airbag is gourd-shaped, the middle part of the plugging airbag is recessed to form a sealing part which can be engaged at the anus, and the sealing part divides the plugging airbag into a spherical clamping part which elastically presses against the inside and outside of the anus, the clamping part is two, presses against the inside and outside of the anus, and the sealing part seals the anus, the plugging airbag is gourd-shaped here, has a good sealing effect, and can better fit the inside and outside of the anus, at the same time, the inner clamping part can be smaller than the diameter of the outer part, the inner clamping part performs inner rectal plugging to prevent the medicinal solution from flowing out, presses against the anus at the same time, and seals the outer part at the same time, so that the inner anorectal plugging, the inner anus is pressed against, the sealing part is pressed against the anus, and the outer anus is pressed against, so as to avoid leakage.
[0005] Preferably, the injection mechanism includes a syringe-type injection barrel, an injection piston installed in the injection barrel, a push rod connected to the injection piston, and a push handle installed at the end of the push rod. The catheter is connected to the end of the injection barrel, and a liquid outlet is provided at the outer end of the catheter.
[0006] Preferably, it also includes an inflation mechanism for inflating the blocking airbag. The blocking airbag is inflated by the inflation mechanism, so that when it is inserted, the volume is small and it is convenient to put in, and the blocking is performed after inflation.
[0007] Preferably, the inflation mechanism is a push type and is installed between the push handle and the push rod so as to inflate the sealing airbag simultaneously when injecting the liquid medicine. When injecting the liquid medicine, the inflation mechanism utilizes this thrust to inflate the sealing airbag. The greater the force for injecting the liquid medicine, the more liquid medicine, the greater the rectal pressure, and the easier the liquid medicine flows out. While the greater the thrust, the more the inflation mechanism inflates, so that the pressure of the sealing airbag is also greater and the sealing effect is increased, thus avoiding the outflow of the liquid medicine.
[0008] Preferably, the inflation mechanism includes a cylinder sleeved on the push rod in a matching manner, and the other end of the cylinder is fixedly sealed on the push handle. A sealing inflation piston is arranged at the end of the push rod, and the cylinder is connected with an inflation pipe. The inflation pipe penetrates into the catheter and communicates with the inner cavity of the sealing airbag. The inflation pipe penetrates into the catheter from the side close to the syringe, so that it will not contact the anus and avoid liquid leakage.
[0009] Preferably, an elastic member is further arranged between the push rod and the bottom of the inner cavity of the cylinder to achieve elastic return. The elastic member can help the cylinder return better.
[0010] Preferably, the elastic member is a spring, which facilitates the better return of the cylinder.
[0011] Preferably, the push rod is columnar, and a limiting mechanism is further arranged between the cylinder and the push rod. The limiting mechanism can engage the cylinder and the push rod when rotating, and the limiting mechanism engages when the cylinder rotates and at the same time limits the slippage when withdrawing the liquid medicine outward.
[0012] Preferably, the limiting mechanism includes vertical sliding grooves opened on the left and right sides of the push rod and sliders inserted into the sliding grooves. The sliding grooves limit the outward sliding of the sliders, ensuring the normal extraction of the liquid medicine. The sliders are fixed on the inner wall of the cylinder, and there are also two sliders on the left and right. A plurality of clamping grooves are arranged on the push rod along the vertical direction for the sliding grooves. The clamping grooves and the sliding grooves are in a "丰" shape, so that the sliders can slide into different clamping grooves to ensure different pressures of the sealing airbag. It should be noted that when the cylinder rotates here, the push rod will not rotate because the resistance of the injection piston is very large and it presses against the inner wall of the syringe. At the same time, for the convenience of the rotation and movement of the sliders, clearance settings can be made between the sliding grooves and the clamping grooves, and the corners are transitioned with arcs. And when the sliders rotate circumferentially along the push rod, they can be clamped into the clamping grooves to achieve limiting.
[0013] Preferably, an anti - detachment airbag for anti - detachment is circumferentially arranged at the end of the catheter, and the inflation pipe extends along the catheter and is connected with the anti - detachment airbag. After inflation, it abuts against the inner wall of the rectum and is not easy to slip off.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. The sealing airbag elastically presses against the anus, the inside and outside of the anus, thereby achieving elastic sealing, avoiding leakage, and ensuring the total enema drug dosage;
[0016] 2. As the liquid medicine is pushed, the air cylinder slides on the push rod and sends the gas into the blocking airbag. At the beginning, there is no thrust, and the blocking airbag is in a contracted state, which is convenient for delivery into the rectum. As the liquid medicine is injected, the thrust increases, the blocking airbag is inflated, and the anus is blocked to avoid leakage. Moreover, the greater the thrust, the greater the pressure of the blocking airbag, and the better the blockage. When withdrawing, the gas in the blocking airbag is withdrawn, shrinking, and the volume is reduced, which is convenient for withdrawal;
[0017] 3. Rotate the push handle and the slider slides into the slot to fix the air cylinder and ensure the pressure of the sealing airbag. It is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0024] See also Figures 1 to 4The present invention provides a technical solution of an anal elastic blocking enema: an anal elastic blocking enema, comprising an injection mechanism for pushing and injecting a medicinal solution and a catheter 1 connected to the injection mechanism, the injection mechanism is used for pushing and injecting a medicinal solution, the injection mechanism comprises a syringe-type injection barrel 4, an injection piston 5 installed in the injection barrel 4, a push rod 6 connected to the injection piston 5, and a push handle 7 installed at the end of the push rod 6, the catheter 1 is connected to the end of the injection barrel 4, and a liquid outlet is arranged at the outer end of the catheter 1. The injection mechanism is sleeved with a blocking airbag 2 which can expand after inflation, and the blocking airbag 2 is gourd-shaped, and the middle part of the blocking airbag 2 is recessed to form a sealing part 3 which can be snapped into the anus, and the sealing part 3 divides the blocking airbag 2 into spherical clamping parts which are elastically pressed against the inside and outside of the anus, and there are two clamping parts which press against the inside and outside of the anus, and the sealing part 3 seals the anus. Here, the blocking airbag 2 is gourd-shaped, with good sealing effect, and can better fit the inside and outside of the anus. At the same time, the inner clamping part can be smaller than the diameter of the outer part, and the inner clamping part seals the inner rectum to prevent the outflow of the medicine, and presses against the anus to seal, and the outer part is also blocked at the same time, so that the inner anorectal blocking, the inner anus pressing, the sealing part 3 pressing against the anus, and the outer anus pressing are achieved to avoid leakage.
[0025] It also includes an inflation mechanism for inflating the blocking airbag 2. The blocking airbag 2 is inflated by the inflation mechanism, so that when inserted, the volume is small and it is convenient to put in, and the blocking is performed after inflation. The inflation mechanism is a push-type, and the inflation mechanism is installed between the push handle 7 and the push rod 6, so that the blocking airbag 2 is inflated at the same time when the liquid medicine is injected. When the inflation mechanism pushes the liquid medicine, the thrust is used to inflate the blocking airbag 2. The greater the force of pushing the liquid medicine, the more liquid medicine, the greater the rectal pressure, and the easier it is for the liquid medicine to flow out. The greater the thrust, the more the inflation amount of the inflation mechanism, so that the pressure of the blocking airbag 2 is also greater, and the blocking effect is also increased, thereby preventing the liquid medicine from flowing out. The inflation mechanism includes an air cylinder 8 which is sleeved on the push rod 6, and the other end of the air cylinder 8 is sealed and fixed on the push handle 7. An inflation piston 9 for sealing is provided at the end of the push rod 6, and the air cylinder 8 is connected to an inflation tube 10. After the inflation tube 10 passes through the catheter 1, it is connected with the inner cavity of the blocking airbag 2. The inflation tube 10 passes through the side of the catheter 1 close to the syringe 4, so that it will not touch the anus to avoid leakage.
[0026] It also includes an elastic component arranged between the push rod 6 and the bottom of the inner cavity of the gas cylinder 8 to achieve elastic return. The elastic component can help the gas cylinder 8 to return better. The elastic component is a spring 11, which facilitates the gas cylinder 8 to return better.
[0027] The push rod 6 is columnar, and further includes a limiting mechanism disposed between the air cylinder 8 and the push rod 6. The limiting mechanism can engage the air cylinder 8 and the push rod 6 when rotating. The limiting mechanism engages when the air cylinder 8 rotates and at the same time restricts slippage when drawing out the liquid medicine outward. The limiting mechanism includes vertical chutes 12 opened on the left and right sides of the push rod 6 and sliders 13 inserted into the chutes 12. The chutes 12 restrict the outward sliding of the sliders 13, ensuring normal extraction of the liquid medicine. The sliders 13 are fixed on the inner wall of the air cylinder 8, and there are also two sliders 13 on the left and right. The chutes 12 are provided with a plurality of card slots 14 opened on the push rod 6 along the vertical direction. The card slots 14 and the chutes 12 are in a "丰" shape, so that the sliders 13 can slide into different card slots 14 to ensure different pressures for the sealing airbag 2. It should be noted that when the air cylinder 8 rotates here, the push rod 6 does not rotate because the resistance of the injection piston 5 is very large and it presses tightly against the inner wall of the syringe barrel 4. At the same time, in order to facilitate the rotation and movement of the sliders 13, there can be a clearance between the sliders 13 and the chutes 12 and the card slots 14. At the corners, there is an arc transition, and the sliders 13 can be engaged with the card slots 14 when rotating circumferentially along the push rod 6 to achieve limiting.
[0028] The end of the catheter 1 is circumferentially provided with an anti - detachment bladder 15 for anti - detachment, and the inflation tube 10 extends along the catheter 1 and is connected to the anti - detachment bladder 15. After inflation, it abuts against the inner wall of the rectum and is not easy to slip off.
[0029] Working principle: The sealing airbag 2 elastically abuts against the anus, the inner side of the anus, and the outer side of the anus, thereby achieving elastic sealing and avoiding liquid leakage. As the liquid medicine is injected, the air cylinder 8 slides on the push rod 6 to send gas into the sealing airbag 2. At the beginning, without thrust, the sealing airbag 2 is in a contracted state, which is convenient for being sent into the rectum. As the liquid medicine is injected, the thrust increases, and the sealing airbag 2 is inflated to achieve anal sealing and avoid liquid leakage. Moreover, the greater the injection force, the greater the pressure of the sealing airbag 2 and the better the sealing. When drawing out, the gas in the sealing airbag 2 is drawn out, realizing contraction and volume reduction, which is convenient for drawing out. Rotating the push handle 7, the slider 13 slides into the card slot 14 to fix the air cylinder 8 and ensure the pressure of the sealing airbag 2, which is simple and convenient.
