[0002] Enema is a treatment method in which a catheter is inserted from the anus through the rectum to the colon to infuse liquid in order to achieve the purpose of defecation and gas discharge. It can stimulate intestinal peristalsis, soften and clear feces, and has the effects of cooling, inducing labor, diluting intestinal toxins, and reducing absorption. Low-temperature solutions can cool down patients with high fever. In addition, it can also achieve therapeutic purposes such as supplying medicines, nutrition, and water.

[0003] The existing enema devices for gastroenterology have the following problems: When the existing gastroenterology enema device uses a syringe with a relatively large diameter, when the syringe is pulled out of the anus after injection, the anus does not contract in time, causing the liquid injected into the intestine to flow out, thereby reducing the enema effect. Therefore, it cannot meet the existing demand for the use of gastroenterology enema devices. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an enema device for gastroenterology that can ensure that when the syringe is pulled out of the anus, the liquid entering the patient's intestine will not flow out of the patient's anus as the syringe is pulled out.

[0005] The technical solution adopted in this scheme is as follows: This scheme proposes an enema device for gastroenterology, including a placement table, a bracket, a direct-entry liquid filling mechanism and an equal-contraction type extraction mechanism. The bracket is symmetrically arranged on the upper walls at both ends of the placement table, the direct-entry liquid filling mechanism is arranged on the bracket, and the equal-contraction type extraction mechanism is arranged on the direct-entry liquid filling mechanism. The direct-entry liquid filling mechanism includes a direct-entry mechanism, a liquid filling mechanism and a lubricating mechanism. The direct-entry mechanism is arranged on the upper wall of the bracket, the liquid filling mechanism is arranged on the upper wall of the placement table, and the lubricating mechanism is arranged on the side wall of the direct-entry mechanism. The equal-contraction type extraction mechanism includes a first-stage component, a second-stage component and a locking component. The first-stage component is arranged inside the direct-entry mechanism, the second-stage component is arranged inside the first-stage component, and the locking component is arranged at one end of the direct-entry mechanism.

[0006] As a further preferred embodiment of the present invention, the straight-in mechanism includes a straight-in body, a rounded head and a push-in plate, wherein the straight-in body is arranged on the upper wall of the bracket, the rounded head is arranged on one side of the straight-in body, and the push-in plate is arranged on the side of the straight-in body away from the rounded head; the liquid filling mechanism includes a guide port, a liquid box, a liquid pump and a telescopic hose, wherein the guide port is arranged between the straight-in body, the rounded head and the push-in plate, the liquid box is arranged on the upper wall of the placement table, the liquid pump is arranged on the side of the liquid box close to the push-in plate, the liquid pumping end of the liquid pump is arranged through the inside of the liquid box, and the telescopic hose is arranged at the liquid discharge end of the liquid pump; The lubrication mechanism includes an annular groove, an oil-coated ring plate, an oil outlet, an oil supply cylinder, a booster pump and an oil supply pipe, wherein the annular groove is arranged on the side wall of the rounded head, and the annular groove is open at one end. The oil-coated ring plate is arranged on the inner wall of the annular groove, and the side wall of the oil-coated ring plate is horizontally arranged with the side wall of the rounded head. A plurality of groups of oil outlets are arranged on the side wall of the oil-coated ring plate, and a plurality of groups of oil supply cylinders are arranged on the side of the push plate away from the straight-entry body. The booster pump is arranged on the side of the oil supply cylinder away from the push plate, and the power end of the booster pump is arranged through the inside of the oil supply cylinder, and the oil supply pipe passes through the straight-entry body, the rounded head, and the push plate and is connected between the oil supply cylinder and the annular groove.

[0007] When in use, lubricating oil is deposited into the oil supply cylinder, and the lubricating oil is applied to the side of the rounded head away from the straight-in body. The straight-in body is lifted up by the pushing plate, and the straight-in body drives the rounded head away from the upper wall of the bracket, and the rounded head contacts the patient's anus, pushes the pushing plate, and the pushing plate drives the rounded head through the patient's anus and enters the intestine through the straight-in body. As the depth of the rounded head increases, it is necessary to maintain the lubrication of the contact between the rounded head and the inner wall of the patient's intestine. At this time, the booster pump increases the pressure to the inside of the oil supply cylinder through the power end. After the internal pressure of the oil supply cylinder increases, the lubricating oil stored in it flows into the annular groove through the oil supply pipe. The annular groove applies the lubricating oil between the side wall of the rounded head and the inner wall of the patient's intestine through the oil outlet, thereby reducing the chance of damage to the patient's intestine. When the rounded head reaches the deep part of the intestine, the telescopic hose is connected to the guide port, and the liquid extraction pump transports the enema liquid in the liquid tank to the inside of the guide port through the liquid extraction end. The guide port inputs the enema liquid into the patient's intestine through the rounded head, thereby completing the enema operation on the patient.

[0008] Preferably, the one-stage component comprises a tube, a round head, a spring and a plate, the tube is arranged inside the guide port, the round head is arranged at one end of the tube away from the push-in plate, the plate is arranged at one end of the tube away from the round head, and the spring is arranged between the push-in plate and the one-stage plate outside the tube; the two-stage component comprises two tubes, two round heads, two plates and two springs, the two tubes are arranged inside the tube, the side of the telescopic hose away from the liquid pump is connected to the two tubes, the two round heads are arranged At one end of the two-section tube close to the first round head, the two-section plate is arranged at one end of the two-section tube close to the first-section plate, and the two-section spring is arranged between the second-section plate and the first-section plate on the outside of the two-section tube; the locking assembly includes a locking rod and a distance-adjusting nut, the locking rod passes through the first-section plate and the second-section plate and is arranged on the side of the push-in plate away from the straight-in body, the locking rod is arranged below the first-section tube and the second-section tube, and the distance-adjusting nut is respectively arranged on the outside of the locking rod on the side of the first-section plate close to the push-in plate and the outside of the locking rod on the side of the second-section plate close to the push-in plate, and the distance-adjusting nut is threadedly connected with the locking rod.

[0009] During use, after the medical staff has finished the enema for the patient, in order to prevent the enema liquid from flowing out of the patient's anus during the process of pulling out the rounded head, the distance adjusting nuts on one side of the first plate and the second plate are rotated respectively, and the distance adjusting nuts rotate along the locking rod toward one end close to the pushing plate, and the medical staff uses the deformation of the second-stage spring to push the second-stage plate, and the distance between the second-stage plate and the first-stage plate is reduced. The second-stage plate uses the deformation of the first-stage spring to push the first-stage plate, and the distance between the first-stage plate and the pushing plate is reduced. The second-stage plate drives the distance between the second-stage round head and the rounded head to increase, and the first-stage plate drives the distance between the first-stage round head and the rounded head to increase. At this time, the second-stage round head and the first-stage plate are The spacing between the segmented round heads increases, and the inner wall of the patient's intestine fits with the first and second segmented round heads respectively. When the medical staff pulls the rounded head out of the patient's anus, the first segmented round head fits with the patient's intestine, so that the enema liquid will not flow out of the patient's anus. When the medical staff pulls the second segmented component out of the patient's anus, the second segmented round head fits with the inner wall of the patient's intestine, so that the enema liquid will not flow out of the patient's anus. When the medical staff pulls the second segmented round head out of the patient's anus, since the diameter of the second segmented round head is the smallest, the patient's anus can quickly retract and close, so that the enema liquid will not flow out of the patient's intestine, thereby improving the enema efficiency of the patient to a certain extent.

[0010] Specifically, the diameter of the rounded head is greater than the diameter of the first-stage round head, and the diameter of the first-stage round head is greater than the diameter of the second-stage round head.

[0011] The beneficial effects achieved by adopting the above structure are as follows: Compared with the prior art, the present invention adopts a segmented withdrawal structure. By setting a direct-entry liquid filling mechanism and an equal-retraction type extraction mechanism, the direct-entry mechanism, the liquid filling mechanism, the lubrication mechanism, the first-stage component, the second-stage component and the locking component cooperate with each other to ensure that when the syringe is pulled out of the anus, the liquid entering the patient's intestine will not flow out of the patient's anus as the syringe is pulled out. Since the diameter of the second-stage round head is the smallest, the patient's anus can be quickly retracted and closed, so that the enema liquid will not flow out of the patient's intestine, thereby improving the enema efficiency of the patient to a certain extent.

[0020] The diameter of the fillet head 6 is greater than the diameter of the first round head 23 , and the diameter of the first round head 23 is greater than the diameter of the second round head 28 .

[0021] When in use, lubricating oil is pre-deposited into the oil supply cylinder 17, and lubricating oil is applied to the side of the rounded head 6 away from the straight-in body 5. The straight-in body 5 is lifted by the push plate 7, and the straight-in body 5 drives the rounded head 6 away from the upper wall of the bracket 2, and the rounded head 6 contacts the anus of the patient; The medical staff pushes the push plate 7, and the push plate 7 drives the rounded head 6 through the patient's anus and into the intestine through the straight-in body 5. As the rounded head 6 goes deeper, it is necessary to maintain the lubrication of the rounded head 6 in contact with the inner wall of the patient's intestine. At this time, the booster pump 18 is started, and the booster pump 18 increases the pressure inside the oil supply cylinder 17 through the power end.

The medical staff uses the deformation of the second-stage spring 30 to push the second-stage plate 29, and the distance between the second-stage plate 29 and the first-stage plate 25 is reduced. The second-stage plate 29 uses the deformation of the first-stage spring 24 through the second-stage spring 30 to push the first-stage plate 25, and the distance between the first-stage plate 25 and the push-in plate 7 is reduced. The second-stage plate 29 drives the distance between the second-stage round head 28 and the rounded head 6 to increase, and the first-stage plate 25 drives the distance between the first-stage round head 23 and the rounded head 6 to increase. At this time, the spacing between the second-stage round head 28 and the first-stage round head 23 increases, and the patient's intestinal inner wall is respectively fitted with the first-stage round head 23 and the second-stage round head 28; When the medical staff pulls the rounded head 6 out of the patient's anus, the first round head 23 fits against the patient's intestine, so that the enema liquid will not flow out of the patient's anus. When the medical staff pulls the second-stage component 26 out of the patient's anus, the second-stage round head 28 fits against the inner wall of the patient's intestine, so that the enema liquid will not flow out of the patient's anus. When the medical staff pulls the second-stage round head 28 out of the patient's anus, the diameter of the second-stage round head 28 is the smallest, and therefore, the patient's anus can quickly retract and close, so that the enema liquid will not flow out of the patient's intestine, completing the enema operation on the patient, and improving the enema efficiency of the patient to a certain extent; the above operation can be repeated the next time it is used.
