Description

Technical Field

[0001] The invention relates to the technical field of enema medicine delivery, in particular to an enema medicine delivery device for preventing abdominal cavity infection. Background Art

[0002] Enema is a technique that infuses a certain amount of liquid from the anus through the rectum into the colon to help patients clean their intestines, defecate, pass gas, or supply medicine from the intestines to achieve the purpose of diagnosis and treatment. According to the purpose of enema, it can be divided into retention enema and non-retention enema.

[0003] The so-called retention enema refers to the process of injecting a prepared drug into the intestines and retaining it for a period of time. It is mainly used to treat intestinal diseases, such as common constipation and enteritis. The treatment can effectively promote defecation, exhaust, and eliminate inflammation. The common enema method is to inject the drug through a catheter.

[0004] The catheter injection method is to directly insert the catheter into the patient's anus, clamp it with tools (hands, pliers) and continue to push the catheter into the patient's body until it reaches the patient's affected area; because the catheter is directly exposed to the air, the cleanliness of the catheter inserted into the patient's body cannot be effectively controlled.

[0043] 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.

[0044] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0045] See also Figures 1 to 9 In the embodiment of the present invention, it includes a support plate 1 and a pressing plate 4 arranged on the support plate 1;

[0046] The pressing plate 4 is fixedly mounted with a connecting column 403, the connecting column 403 is fixedly mounted with a medicine liquid plate 7, the medicine liquid plate 7 is fixedly mounted with a medicine bag 10; the medicine bag 10 is fixedly connected with a liquid outlet plate 8, the liquid outlet plate 8 is rotatably mounted with a catheter 11 connected with the medicine bag 10;

[0047] An anti-fouling sleeve 2 is fixedly mounted on one surface of the support plate 1, and a plurality of groups of anal plugs 5 are arranged on the anti-fouling sleeve 2, and the plurality of groups of anal plugs 5 are arranged around the catheter 11; and the catheter 11 passes through the anti-fouling sleeve 2 and is slidably connected with the anal plugs 5;

[0048] The support plate 1 is provided with a pushing structure. When the pressing plate 4 is driven to approach the support plate 1 by an external force, the pushing structure drives the catheter 11 to slide in the anal plug 5 in a direction away from the support plate 1, and the catheter 11 rotates during the sliding process.

[0049] The support plate 1 is also provided with a medicine feeding structure, and when the pushing structure is in motion, it can drive the medicine feeding structure to move, so as to drive the liquid outlet plate 8 to approach the medicine liquid plate 7, thereby driving the medicine bag 10 to shrink toward the medicine liquid plate 7, so that the medicine liquid is discharged from the catheter 11.

[0050] Taking the embodiment combining all the features recorded in this application as an example, when in use, the medical staff holds the medicine delivery device and first inserts the anal plug 5 into the patient's anus. The anal plug 5 can reduce the difficulty of inserting the catheter 11 into the anus, thereby improving the success rate of the medicine delivery device.

[0051] Afterwards, an external force is applied to the pressing plate 4 to move toward the supporting plate 1. At this time, the distance between the pressing plate 4 and the supporting plate 1 will gradually decrease, and the pushing structure will be driven to move. The pushing structure will drive the catheter 11 and the anal plug 5 to slide and cooperate, so that the catheter 11 is gradually pushed into the patient's body, and the catheter 11 will rotate during the pushing process, thereby reducing the difficulty of the catheter 11 moving in the patient's intestine, thereby improving the success rate of the drug delivery device, and the rotational pushing method can reduce the patient's discomfort.

[0052] When the push structure drives the catheter 11 to move to the patient, the push mechanism drives the medicine loading structure to move, and the medicine loading structure drives the liquid outlet plate 8 to move closer to the medicine liquid plate 7, thereby compressing the medicine capsule 10, and the medicine capsule 10 contracts, so that the medicine liquid in the medicine capsule 10 is squeezed into the catheter 11 and discharged to the patient's affected part through the catheter 11. The action of the push structure drives the action of the medicine loading structure, which can make the operation of medical staff more convenient and reduce medical care costs.

[0053] Since the catheter 11 inserted into the patient's body is always in the anti-fouling sleeve 2 before the pushing structure is activated, the catheter 11 entering the patient's body is in a relatively clean state, which can effectively reduce the probability of infection in the patient's abdominal cavity due to enema; and after use, by removing the anal plug 5 from the anti-fouling sleeve 2, the drug delivery device can be easily cleaned to prevent cross infection.

[0054] According to another embodiment of the present invention, the pushing structure includes a connecting plate 401 fixedly mounted on the pressing plate 4, a connecting ring 402 fixedly mounted on one end of the connecting plate 401 away from the pressing plate 4, the connecting ring 402 is wrapped around the conduit 11, a slider 6 slidably connected to the anti-fouling sleeve 2 is rotatably mounted on the connecting ring 402, the slider 6 is fixedly connected to the conduit 11, a protruding column 601 is fixedly mounted on the slider 6, and a spiral groove 201 slidably engaged with the protruding column 601 is opened in the anti-fouling sleeve 2.

[0055] Taking the embodiment combining all the features recorded in the present application as an example, when in use, an external force is applied to the pressing plate 4 to approach the support plate 1, and the distance between the pressing plate 4 and the support plate 1 will continue to decrease, and the pressing plate 4 will drive the connecting plate 401 and the connecting ring 402 to move synchronously, thereby driving the slider 6 to slide in the anti-fouling sleeve 2 toward the anal plug 5. During the sliding process, the protruding column 601 will slide and rub against the spiral groove 201, thereby driving the slider 6 to rotate in the anti-fouling sleeve 2; since the slider 6 is fixedly connected to the catheter 11, and the axes of the slider 6 and the catheter 11 are colinear, the slider 6 can drive the catheter 11 to move synchronously, so that the catheter 11 can rotate and move into the patient's intestine.

[0056] By applying an external force to the pressing plate 4 to move toward the supporting plate 1, the distance between the pressing plate 4 and the supporting plate 1 will gradually decrease, and the pushing structure will be driven to move. The pushing structure will drive the catheter 11 and the anal plug 5 to slide and cooperate, so that the catheter 11 is gradually pushed into the patient's body, and the catheter 11 will rotate during the pushing process, thereby reducing the difficulty of the catheter 11 moving in the patient's intestine, thereby improving the success rate of the drug delivery device, and the rotational pushing method can reduce the patient's discomfort.

[0057] According to another embodiment of the present invention, the medicine applying structure includes a sliding rod 101 fixedly mounted on the support plate 1, the sliding rod 101 is slidably connected to the pressing plate 4, a baffle 102 is fixedly mounted on the end of the sliding rod 101, a buffer spring 3 is wrapped around the sliding rod 101, and both ends of the buffer spring 3 are fixedly connected to the pressing plate 4 and the support plate 1, respectively.

[0058] Taking the embodiment combining all the features recorded in this application as an example, when in use, when the pressing plate 4 approaches the support plate 1, it will drive the medicine liquid plate 7 to synchronously move toward the support plate 1 through the connecting column 403; and the medicine liquid plate 7 will drive the liquid outlet plate 8 to synchronously move toward the pressing plate 4.

[0059] In the initial position, the buffer spring 3 is compressed, and its elastic force drives the pressing plate 4 to contact the baffle 102. When the pressing plate 4 approaches the support plate 1, the pressing plate 4 will slide and rub against the slide bar 101. The buffer spring 3 will be further compressed, while the baffle 102 remains in position.

[0060] The length of the slide bar 101 is much greater than the distance between the pressing plate 4 and the liquid outlet plate 8. When the pressing plate 4 compresses the buffer spring 3 to the maximum compression position, the pushing structure drives the catheter 11 to extend to the maximum extent.

[0061] As the pressing plate 4 approaches the support plate 1, the distance between the liquid outlet plate 8 and the baffle 102 will gradually decrease, and when the catheter 11 reaches the starting point of the patient's affected part (range medication), the liquid outlet plate 8 and the baffle 102 will collide, and then the pressing plate 4 will continue to move toward the support plate 1, and the catheter 11 will continue to move into the patient's body until the catheter 11 reaches the end of the patient's affected part. In this process, under the interference of the baffle 102, the distance between the liquid plate 7 and the liquid outlet plate 8 will gradually decrease, so that the medicine bag 10 is continuously compressed, so that the liquid medicine is squeezed from the medicine bag 10 into the catheter 11, and the liquid medicine is discharged to the patient's affected part through the catheter 11.

[0062] The elastic force of the buffer spring 3 can prevent the pressing plate 4 from approaching the supporting plate 1 too quickly, thereby protecting the patient and preventing the patient's intestines from being injured by the fast-moving catheter 11, reducing the patient's discomfort. It can also reduce the speed at which the liquid outlet plate 8 and the drug liquid plate 7 approach too quickly, preventing the patient from feeling uncomfortable due to the too-fast discharge of drug liquid by the catheter 11.

[0063] By driving the medicine-applying structure action through the pushing structure action, it can make the operation more convenient for medical staff and reduce the medical care cost.

[0064] In another embodiment of the present invention, a telescopic sleeve 701 is fixedly mounted on the medicine liquid plate 7, a telescopic column 801 slidably engaged with the telescopic sleeve 701 is fixedly mounted on the liquid outlet plate 8, and a reset spring 9 fixedly mounted on the telescopic column 801 and fixedly connected to the medicine liquid plate 7.

[0065] Taking the embodiment combining all the features recorded in the present application as an example, when in use, the liquid outlet plate 8 is displaced toward the medicine liquid plate 7 under the resistance of the baffle 102, and the liquid outlet plate 8 drives the telescopic column 801 to slide inward in the telescopic sleeve 701 and compresses the reset spring 9; after the medicine is applied, the elastic force of the reset spring 9 will drive the telescopic column 801 to slide outward in the telescopic sleeve 701 to complete the reset, so as to facilitate the cleaning of the medicine bag 10 and facilitate the next use.

[0066] In another embodiment of the present invention, a limiting column 802 is fixedly installed on the telescopic column 801 , a limiting block 803 is fixedly installed on the limiting column 802 , a contraction seam 804 is provided on the limiting column 802 , and a limiting groove 702 is provided on the medicine liquid plate 7 .

[0067] Taking the embodiment combining all the features recorded in the present application as an example, when in use, as the liquid outlet plate 8 drives the telescopic column 801 to slide inward in the telescopic sleeve 701, the limiting column 802 will drive the limiting block 803 to approach the limiting groove 702. When the medicine in the medicine bag 10 is about to be discharged, the limiting block 803 will contact the limiting groove 702.

[0068] The diameter of the limiting column 802 is the same as the aperture of the limiting groove 702. The diameter of the limiting block 803 is slightly larger than the aperture of the limiting groove 702, and the side of the limiting block 803 close to the limiting groove 702 is a sloped surface, and the back side thereof is a flat surface.

[0069] Then, the pressing plate 4 is driven to approach the supporting plate 1 to drive the baffle plate 102 to continue to interact with the liquid outlet plate 8 to drain the liquid medicine in the medicine bag 10. In this process, the limit column 802 will continue to drive the limit block 803 to move, and under the interaction between the slope of the limit block 803 and the limit groove 702, the spacing of the contraction seam 804 will be reduced, so that the limit block 803 and the limit groove 702 will slide and cooperate. When the liquid medicine in the medicine bag 10 is drained, the limit block 803 passes through the limit groove 702, and the spacing of the contraction seam 804 is restored. Under the mutual conflict between the flat surface of the limit block 803 and the liquid medicine plate 7, the limit block 803 will not be able to move in the reverse direction, so that the telescopic column 801 does not move in the telescopic sleeve 701, and the reset spring 9 keeps the deformation unchanged.

[0070] After the medicine applying structure completes applying medicine to the patient's affected area, the external force on the pressing plate 4 is removed. At this time, under the elastic force of the buffer spring 3, the pressing plate 4 will be displaced and reset in the direction away from the support plate 1, and drive the slider 6 to slide in the anti-fouling sleeve 2 toward the support plate 1 through the connecting plate 401 and the connecting ring 402. The slider 6 is driven to rotate through the mutual cooperation of the protruding column 601 and the spiral groove 201, thereby driving the catheter 11 to rotate out of the patient's body and be recovered into the anti-fouling sleeve 2. At the same time, due to the interaction between the limit block 803 and the medicine liquid plate 7, the distance between the medicine liquid plate 7 and the liquid outlet plate 8 will remain unchanged. Therefore, during the resetting process of the pressing plate 4, the medicine liquid plate 7 is driven gradually away from the pressing plate 4 through the connecting column 403 to complete the resetting; the liquid outlet plate 8 will separate from the baffle 102, and then an external force will be applied to the limit block 803 to reduce the distance between the contraction seam 804, and under the elastic force of the reset spring 9, the limit block 803 will move toward the pressing plate 4 and pass through the limit groove 702 in the reverse direction, and the telescopic column 801 will slide outward in the telescopic sleeve 701 until the liquid outlet plate 8 drives the medicine bag 10 to complete the resetting.

[0071] The interaction between the limiting block 803 and the medicine liquid plate 7 makes the medicine capsule 10 in a compressed state during the resetting process of the pressing plate 4, thereby preventing the medicine liquid from flowing back and effectively improving the medicine delivery efficiency of the medicine delivery device.

[0072] According to another embodiment of the present invention, a mounting plate 12 is threadedly connected to the anti-pollution sleeve 2, a plurality of guide grooves 1202 are provided on the mounting plate 12, a guide plate 1201 is fixedly installed on the mounting plate 12, and the guide plate 1201 is located on a side of the guide groove 1202 away from the anti-pollution sleeve 2; a yield block 501 slidably connected to the guide groove 1202 is fixedly installed on the anal plug 5, a guide rod 502 slidably connected to the guide plate 1201 is fixedly installed on the yield block 501, a yield spring 13 is wrapped around the guide rod 502, and two ends of the yield spring 13 respectively contact the yield block 501 and the guide plate 1201; a locking groove 202 is provided on the anti-pollution sleeve 2, a locking sleeve 14 is slidably installed on the anti-pollution sleeve 2, and a raised column 1401 slidably engaged with the locking groove 202 is fixedly installed in the locking sleeve 14.

[0073] Taking the embodiment combining all the features described in the present application as an example, when in use, in the initial state, the multiple groups of anal plugs 5 contact each other to seal the catheter 11 in the anti-fouling sleeve 2 to prevent the external environment from contaminating the surface of the catheter 11 during storage.

[0074] The butt plug 5 is inserted into the anus of the patient, and the mounting plate 12 can limit the depth of the butt plug 5 inserted into the anus; the locking groove 202 is composed of a vertical groove perpendicular to the mounting plate 12 and an annular groove parallel to the mounting plate 12; then, an external force is applied to the locking sleeve 14 to make it slide toward the mounting plate 12, at which time the protruding column 1401 will slide and cooperate with the vertical groove of the locking groove 202; and during the sliding process, the locking sleeve 14 will conflict with the giving block 501, and after the conflict, the locking sleeve 14 will slide and conflict with the giving block 501 ; The side of the giving block 501 close to the locking sleeve 14 is inclined. After the locking sleeve 14 contacts the inclined surface of the giving block 501, the external force on the locking sleeve 14 will drive the giving block 501 to slide in the guide groove 1202 toward the guide plate 1201, compressing the giving spring 13; in this process, the anal plug 5 will move synchronously with the giving block 501, so that multiple groups of anal plugs 5 are separated from each other, thereby slightly stretching the patient's anus and releasing the closed state of the catheter 11, so that the catheter 11 can be inserted into the patient's body. After that, when the locking sleeve 14 is rotated, the protruding column 1401 will enter the annular groove from the vertical groove, and the groove wall of the annular groove and the protruding column 1401 will conflict with each other, thereby preventing the locking sleeve 14 from moving away from the mounting plate 12, thereby keeping the position of the anal plug 5 unchanged, so as to avoid the catheter 11 being clamped by the anal plugs 5 that are close to each other during the process of the catheter 11 being inserted into the patient's body under the action of the pushing structure, resulting in failure of drug application.

[0075] After the medicine application is completed, the threaded connection between the anal plug 5 and the anti-fouling sleeve 2 is released to remove the anal plug 5. Removing the anal plug 5 from the anti-fouling sleeve 2 can facilitate cleaning of the medicine delivery device to prevent cross infection.

[0076] In another embodiment of the present invention, the medicine capsule 10 is made of soft rubber and has a hollow structure.

[0077] Taking the embodiment combining all the features described in the present application as an example, when in use, squeezing the medicine bag 10 can ensure that the drug solution can be discharged from the medicine bag 10 into the catheter 11 .

[0078] In another embodiment of the present invention, an anti-slip groove 103 is provided on the support plate 1 , and a thumb plate 404 is fixedly mounted on the pressing plate 4 .

[0079] Taking the embodiment combining all the features recorded in the present application as an example, when in use, the anti-slip groove 103 can increase the stability of the medical staff holding the support plate 1, and prevent the support plate 1 from falling off during the medication process, resulting in medication failure. The thumb plate 404 can reduce the difficulty of pressing the pressing plate 4, making it convenient for medical staff to operate.
