[0020] EMBODIMENT
[0021] The enema device described in the embodiment, as shown in Figure 1As shown, including enema body 1, enema body 1 is the existing known product, the enema body 1 in the design of the present application is composed of liquid storage bag 1.1, catheter 1.2, flow rate regulator 1.3 and hose 1.4; liquid storage bag 1.1 is used for storing enema liquid, the top of liquid storage bag 1.1 is the position of the bag mouth, the top of liquid storage bag 1.1 is provided with a rope; one end of hose 1.4 is provided with a water outlet hole, Figure 1 The upper end of the hose 1.4 is the position of the water outlet hole; the flow rate regulator 1.3 is like the adjusting valve on the infusion device, and its working principle is to change the size of the liquid passage by pushing the pulley to extrude the pipeline, so as to adjust the flow rate; during installation, one end of the catheter 1.2 is connected with the liquid outlet end of the liquid storage bag 1.1, and the other end is connected with the hose 1.4; the flow rate regulator 1.3 is installed on the catheter 1.2; during use, first, the rope on the liquid storage bag 1.1 is hung on the medical support frame, then the enema liquid is injected from the top of the liquid storage bag 1.1, then the hose 1.4 is inserted into the intestinal tract from the anus of the patient, then the flow rate regulator 1.3 is opened to make the enema liquid enter into the hose 1.4 from the catheter 1.2, then the enema liquid flows into the intestinal tract of the patient through the water outlet hole on the hose 1.4, and the purpose of enema is achieved;
[0022] As shown in Figure 1 , Figure 2 and Figure 3 , the hose 1.4 on the enema body 1 is independently sleeved with an air bag 6 which can move along the length direction, and the air bag 6 is in the form of a hollow ring structure; the air bag 6 is sleeved on Figure 1The lower end of the soft tube 1.4 is located at the anus of the patient; when the upper end of the soft tube 1.4 is inserted into the intestinal tract of the patient from the anus, the lower end of the soft tube 1.4 will move to the position of the anus of the patient, and when the lower end of the soft tube 1.4 is located in the anus, the air bag 6 will also move to the position of the anus, at this time, the air bag 6 is inflated to expand, so that the diameter of the air bag 6 becomes larger, so that the air bag 6 can be clamped at the position of the anus, so that the air bag 6 can block the position of the anus, and when the enema liquid flows back, the air bag 6 can prevent the enema liquid from leaking out; during the enema process, the depth of the soft tube 1.4 inserted into the intestinal tract varies due to individual differences and enema purposes; in clinical practice, the depth of the enema catheter is usually 15-25 cm, so that the depth of the anal canal reaches the sigmoid colon, reduces the stimulation to the rectum, delays the defecation time, increases the amount of enema liquid, and improves the effect of enema; however, for the elderly, the depth of the catheter is about 20 cm; for children, the depth of the catheter is about 15-20 cm; therefore, during the enema process, the depth of the soft tube 1.4 inserted varies, so that the depth of the soft tube 1.4 inserted can be determined according to different patients, at this time, the air bag 6 can move along the length direction of the soft tube 1.4, so that the position of the air bag 6 on the soft tube 1.4 can be adjusted, so that when the soft tube 1.4 is inserted into the intestinal tract and the anus of the patient, the air bag 6 can be stably located at the position of the anus; avoids the problem that if the position of the air bag 6 is fixedly installed, the air bag 6 may enter the anus or a deeper position in the intestinal tract along with the soft tube 1.4, and avoids the problem that after the insertion of the soft tube 1.4 is completed, the air bag 6 may not enter the anus;
[0023] As Figure 1 , Figure 2 and Figure 3As shown, the hose 1.4 is provided with a limiting ring 5, the outer wall of the limiting ring 5 is fixed on the inner wall of the air bag 6; the limiting ring 5 is made of elastic material; in the natural state of the limiting ring 5, the inner wall of the limiting ring 5 is attached to the outer wall of the hose 1.4; the hose 1.4 is sleeved with a plurality of convex rings 2 along the length direction thereof, and a gap for placing the limiting ring 5 is left between each adjacent two convex rings 2; the overall structure of the scheme in this paragraph constitutes a limiting assembly for limiting the movement of the air bag 6; because the limiting ring 5 is elastic and attached to the outer wall of the hose 1.4, the limiting ring 5 can be tightly sleeved on the outer wall of the hose 1.4 by friction; because the air bag 6 has a ring structure and the outer wall of the limiting ring 5 is fixed on the inner wall of the air bag 6, when the limiting ring 5 is sleeved on the hose 1.4, the position of the air bag 6 can also be limited, thereby preventing the air bag 6 from sliding on the hose 1.4; when the convex ring 2 is installed, the inner wall of the convex ring 2 is fixed on the outer wall of the hose 1.4; the hose 1.4 and the convex ring 2 can be made of polyvinyl chloride material, so the convex ring 2 and the hose 1.4 can be produced by integral molding; because a plurality of convex rings 2 are provided and the limiting ring 5 is elastic, the limiting ring 5 can be pulled apart like a rubber band; because the air bag 6 is also elastic, the air bag 6 can also be pulled apart together; when the limiting ring 5 and the air bag 6 are pulled apart by their elasticity, the limiting ring 5 and the air bag 6 can be placed between different two convex rings 2; when the limiting ring 5 and the air bag 6 stop being pulled, they can be clamped between the two convex rings 2 by their elasticity, thereby limiting the position of the limiting ring 5 and the air bag 6; because a plurality of convex rings 2 are provided, when the limiting ring 5 and the air bag 6 are placed between different two convex rings 2, the position of the limiting ring 5 and the air bag 6 can be adjusted, so through the design of the convex ring 2, the limiting ring 5 and the air bag 6 can be limited at different positions on the hose 1.4, thereby preventing the limiting ring 5 and the air bag 6 from sliding on the hose 1.4 during insertion into the anus, which causes the air bag 6 to not enter the anus; in use, first, the depth of the hose 1.4 inserted into the intestine is determined according to the patient's condition, then the position of the air bag 6 on the hose 1.4 is determined, and then the air bag 6 is placed between the two convex rings 2 at the corresponding position, so the convex ring 2 can limit the position of the air bag 6, allowing the air bag 6 to stably enter the anus;
[0024] In the specific implementation process, the convex ring 2 in the limiting assembly can also be replaced by a convex block, and the limiting ring 5 and the air bag 6 can also be limited at different positions on the hose 1.4 by being placed between different two convex blocks, thereby facilitating the use of different patients;
[0025] As Figure 1As shown, the several convex rings 2 are arranged at equal intervals, preferably the distance between every two adjacent convex rings 2 is equal to the thickness of the limiting ring 5, so that through the design of equal intervals and thickness, the limiting ring 5 is more stably limited between the two convex rings 2, when the hose 1.4 drives the convex ring 2 into the anus, it is possible to ensure that the limiting ring 5 between the two convex rings 2 does not slide, thereby ensuring the stability of the air bag 6;
[0026] As shown in Figure 1 and Figure 2 , the edge of the convex ring 2 is arc-shaped, through the design of arc-shaped structure, when the convex ring 2 enters into the anus, it avoids the problem of scratching the anus, and as far as possible, protects the anus during the operation;
[0027] The limiting ring 5 is made of polyurethane material, and the air bag 6 is made of medical polyurethane material; the limiting ring 5 and the air bag 6 can be produced by one-piece molding during production, thereby improving the stability between the limiting ring 5 and the air bag 6; the polyurethane material has high tensile strength and tear resistance, and also has high elasticity, the elastomer performance of polyurethane is between rubber and plastic, and has good resilience, which makes it perform well in buffering, shock absorption and other applications; polyurethane also has good aging resistance and corrosion resistance, and is suitable for use in variable environments;
[0028] As shown in Figure 1 and Figure 2 , the air bag 6 is provided with a balloon 4, and the upper portion of the balloon 4 is provided with a trachea 3; one end of the trachea 3 is connected with the balloon 4, and the other end is connected with the air bag 6; the whole scheme constitutes an inflation assembly for inflating the air bag 6; the balloon 4 is a known product, and the balloon 4 is provided with a one-way valve, air can enter the balloon 4 from the one-way valve, and the one-way valve ensures that air can only flow from the balloon 4 to the air bag 6, but cannot flow in the opposite direction; the structure of the balloon 4 is the same as that of the balloon on the sphygmomanometer in our life, and the balloon is used to inflate the cuff on the sphygmomanometer; when in use, the balloon 4 is squeezed by hand to compress the gas and enter the inside of the balloon 4 through the valve, so that the gas can enter the air bag 6 through the trachea 3, thereby achieving the purpose of inflation; the connection between the trachea 3 and the balloon 4 can be detachable, for example, the trachea 3 is connected to the balloon 4 by threads, and the interface between the balloon 4 and the trachea 3 is provided with internal and external threads, and the trachea 3 is provided with external threads that are threadedly matched with the internal threads, and the trachea 3 is screwed onto the internal threads of the balloon 4, so that the trachea 3 and the balloon 4 can be easily detached and installed, and after the trachea 3 and the balloon 4 are detached, the air bag 6 can be easily deflated, and the air bag 6 and the hose 1.4 can be easily taken out of the anus; the air bag 6 and the trachea 3 can be made of rubber or latex during production;
[0029] In the specific implementation process, the balloon 4 in the inflation assembly can be replaced by an air pump, which is directly connected with the air pipe 3, and can also realize the inflation and deflation of the air bag 6.
[0030] In the specific use process: first, the liquid storage bag 1.1 is hung on the support frame, then the enema liquid is injected into the liquid storage bag 1.1, then the length of the hose 1.4 inserted into the intestinal tract is determined according to the patient's condition, and then the position of the air bag 6 on the hose 1.4 is determined according to the length, so that the air bag 6 can be located at the position of the anus after the hose 1.4 is inserted into the intestinal tract; after determining the position where the air bag 6 needs to be placed, the limiting ring 5 and the air bag 6 are pulled and placed between the two convex rings 2 at the position by the elasticity of the limiting ring 5 and the air bag 6, so that the two convex rings 2 limit the limiting ring 5 and the air bag 6 at the required position on the hose 1.4, then the hose 1.4 is inserted into the intestinal tract of the patient from the position of the anus, and the air bag 6 can enter the anus with the hose 1.4, at this time, the air bag 6 is inflated by pressing the balloon 4, and when the air bag 6 is inflated, the anus can be blocked, then the flow rate regulator 1.3 is opened to inject the enema liquid into the intestinal tract of the patient, and when the anus of the patient is relaxed or the flow rate of the enema liquid is too fast to flow out from the position of the anus, the inflated air bag 6 can prevent the enema liquid from leaking from the position of the anus; thus, the problem that the enema liquid is easy to leak in the prior art is solved.
