Description
Technical Field
[0001] The utility model relates to the technical field of medical enema devices, in particular to a medical enema auxiliary device. Background Art
[0002] Medical enema is a common medical method. By injecting liquid medicine into the rectum, it can effectively remove stool in the intestine, purify the intestinal environment and treat diseases. It is widely used in many clinical fields such as internal medicine, surgery, obstetrics and gynecology, and rehabilitation. At present, the enema devices commonly used in hospitals generally use enema cannulas for enema. Due to the differences in the length of the rectum of patients of different ages and genders, and the different enema treatment plans for patients with different diseases, the depth of inserting the front end of the enema cannula into the patient's rectum is also different. When inserting the cannula, medical staff can only insert the enema cannula into the patient's rectum based on experience to determine the approximate insertion depth, and it is difficult to accurately control the insertion depth.
[0003] In view of the above technical problems, in the prior art, the authorization announcement number CN205612793U discloses a medical enema device, which uses the insertion depth scale value marked on the outer circle of the front end of the anal canal to enable medical staff to accurately control the depth position of the anal canal entering the patient's anorectum by observing the scale value when inserting the cannula. However, during the actual insertion process of the medical enema device, since the patient's anus is in a hidden position and the anal canal is relatively slender, the scale value mark on the outer wall of the anal canal is small, unclear, and inconvenient to observe, resulting in the medical staff being unable to quickly and accurately grasp the anal canal insertion depth, and the operation is not convenient enough.

The other end is connected with the liquid inlet end of the enema cannula 3, and is used to transfer the liquid in the liquid storage bag 1 to the enema cannula 3. The center of the limiting leak-blocking member 4 is provided with a through hole 7 for the enema cannula 3 to pass through. When performing the enema operation, the enema cannula 3 is passed through the through hole 7 of the limiting leak-blocking member 4, so that the limiting leak-blocking member 4 is sleeved on the enema cannula 3. The position of the limiting leak-blocking member 4 can be adjusted according to the required insertion depth of the enema. The scale 6 on the outer side wall of the enema cannula 3 is used The position of the limit leak plugging piece 4 is marked to facilitate the rapid adjustment of the insertion length of the enema cannula 3. When adjusting the position of the limit leak plugging piece 4, the enema cannula 3 is manually pulled so that the limit leak plugging piece 4 can move along the length direction of the enema cannula 3. During the insertion, the limit leak plugging piece 4 plays a limiting role. When the enema cannula 3 is inserted into place, the limit leak plugging piece 4 blocks the patient's anus to prevent the enema cannula 3 from continuing to be inserted. When performing enema, the liquid storage bag 1 containing the medicine liquid is hung at a high place. The medicine in the liquid storage bag 1 flows into the enema cannula 3 along the catheter 2 under the action of gravity, and flows into the patient's anus and rectum from the drainage hole 5 at the insertion end of the enema cannula 3 for enema operation. During the enema process, the limit leak plugging piece 4 also has the function of plugging leakage. The medical staff or the patient himself can press the limit leak plugging piece 4 at the anus by hand, which can assist the patient to tighten the anus and prevent leakage or defecation during the enema process.
[0019] Please see Figures 2 to 4Further, a receiving groove 8 connected to the through hole 7 is provided on the side wall of the limiting leak plugging member 4, and the receiving groove 8 and the through hole 7 are perpendicular to each other. A movable jacket 9 is provided in the receiving groove 8, and a through hole 10 for the enema cannula 3 to pass through is provided on the jacket 9, and the through hole 10 is parallel to the through hole 7 and is larger than the aperture of the through hole 7. A spring member 11 is provided at the bottom of the receiving groove 8, and the spring member 11 is against the bottom of the jacket 9, and the top of the jacket 9 is exposed outside the notch of the receiving groove 8. By manually pressing the top of the jacket 9, the jacket 9 can be contracted toward the bottom of the receiving groove 8, compressing the spring member 11, and making the through hole 10 on the jacket 9 It coincides with the through hole 7, so that the enema cannula 3 can pass through the through hole 7 and the through hole 10 in sequence, and when the jacket 9 is in the pressed state, the enema cannula 3 and the limiting leak-stopping component 4 can move relative to each other, so that the limiting leak-stopping component 4 can move along the length direction of the enema cannula 3. After the jacket 9 is released, the jacket 9 moves toward the notch direction of the accommodating groove 8 under the tension of the spring component 11, so that the through hole 10 and the through hole 7 are misaligned with each other, forming mutually staggered extrusion forces, and respectively squeezed on the outer side walls of the enema cannula 3, clamping the enema cannula 3 to fix the limiting leak-stopping component 4, which can prevent the limiting leak-stopping component 4 from shifting during the insertion process of the enema cannula 3.
[0020] Please see Figure 3 Furthermore, an elastic sealing ring 12 is annularly arranged on the opening of the through hole 7 of the limiting leak-plugging member 4 toward one end of the discharge hole 5 of the enema cannula 3. The elastic sealing ring 12 is in close contact with the outer wall of the enema cannula 3 and can slide relatively to each other, thereby playing a sealing role to prevent the drug solution or excrement from overflowing from the through hole 7 of the limiting leak-plugging member 4 during the enema process.
[0021] Please see Figure 1 Furthermore, in order to facilitate the intubation operation of the enema cannula 3, a handle 14 is provided at the liquid inlet end of the enema cannula 3, and a control valve 13 is provided at the liquid inlet end of the enema cannula 3. The control valve 13 is used to limit the flow of the liquid medicine entering the enema cannula 3.
[0022] Please continue to see Figure 1 Furthermore, the medical enema auxiliary device also includes a booster 15 and a connecting tube 16, one end of the connecting tube 16 is connected to the output end of the booster 15, and the other end is connected to the inner cavity of the liquid storage bag 1. The booster 15 is a hand-held inflatable ball or air pump. When in use, the patient or medical staff inflates and pressurizes the liquid storage bag 1 through the booster 15, and uses the air pressure to push the liquid in the liquid storage bag 1 to flow toward the enema cannula 3, thereby assisting the enema cannula 3 in discharging liquid.
[0023] When the device is used, the top of the jacket 9 is manually pressed to shrink the jacket 9 toward the bottom of the receiving groove 8, so that the through hole 10 coincides with the through hole 7, and the insertion end of the enema cannula 3 is passed through the through hole 7 and the through hole 10 in sequence. According to the required insertion depth of the enema, the enema cannula 3 is manually pulled to adjust the distance between the insertion end of the enema cannula 3 and the limit plugging member 4. After the jacket 9 is released, the jacket 9 is pressed against the outer wall of the enema cannula 3 under the tension of the spring member 11 to close the limit plugging member 4. The leaking piece 4 is fixed, and when the enema cannula 3 is inserted into place, the limiting leak-blocking piece 4 blocks the patient's anus, and the liquid storage bag 1 storing the medicine liquid is hung at a high place. Under the action of gravity, the medicine liquid in the liquid storage bag 1 flows into the enema cannula 3 along the catheter 2, and flows into the patient's anus and rectum from the drainage hole 5 at the insertion end of the enema cannula 3 to perform the enema operation. During the enema process, the patient can press the limiting leak-blocking piece 4 on the anus by hand, which can help the patient tighten the anus and prevent leakage or defecation during the enema process.
