Description

Technical Field

[0001] The present invention relates to the field of medical appliances, in particular to a digestive tract and rectal medical drug delivery device. Background Art

[0002] The digestive tract is a long muscular tube that starts from the mouth and continues to the pharynx, esophagus, stomach, small intestine, large intestine, and ends at the anal canal. It includes the mouth, pharynx, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, appendix, colon, rectum) and anal canal.

[0003] When a disease of the digestive tract occurs, a gastroenterologist will administer medication. However, treatment requires a certain period of time, and therefore regular medication is required. Medical staff can assist in medication administration while the patient is receiving treatment in the hospital. However, if the patient still needs to continue medication treatment for a period of time after discharge, the patient must do it themselves. In particular, when medication needs to be delivered from the rectum, tools are required. However, in actual use, most existing medication delivery devices are simple syringes with a delivery tube. The delivery tube is inserted into the rectum, and then the syringe is pushed to deliver the medicine. However, when doing it by oneself, due to certain operating space obstacles of the body itself, it is inconvenient to use, the accuracy of medication is poor, and the medicine is prone to dripping and causing secondary contamination. Therefore, we propose a digestive tract rectal medical medication device. Summary of the Invention

[0004] The purpose of the present invention is to provide a digestive tract rectal medical drug delivery device, which solves the problems raised in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a digestive tract rectal medical applicator, comprising a base, a groove formed on the top of the base, a hollow disk fixedly connected to the inner wall of the groove via a fixing rod, a disposable drug delivery tube vertically connected to the top of the hollow disk, a plurality of evenly distributed holes formed on the top of the disposable drug delivery tube, a box fixed to one side of the base, a seat ring connected to a side wall of the box adjacent to the disposable drug delivery tube;

[0006] In actual use, the patient sits on the seat, which then rises and falls, allowing the disposable medication tube to enter the rectum for medication. During the medication process, if dripping occurs, the dripping liquid can be collected by the groove to avoid secondary contamination.

[0007] A first box is fixedly mounted on one side of the inner cavity of the box, a first liquid pump is fixedly mounted on the top of the first box, one end of the first liquid pump is connected to the first box, and the other end of the first liquid pump passes through the box through a first hose and is connected to the hollow disk;

[0008] When delivering medicine into the rectum using the disposable dosing tube, starting the first liquid pump can extract the medicine in the first box, thereby introducing it into the disposable dosing tube and then into the digestive tract along the hole for administration.

[0009] As a preferred embodiment of the present invention, a slide groove is provided on both sides of a side wall of the box body close to the seat ring, a screw motor is fixedly installed on the top of the inner cavity of the slide groove, the outer end of the transmission shaft of the screw motor is fixedly connected to a screw, the outer end of the screw is rotatably connected to the bottom of the inner cavity of the slide groove, the outer wall of the screw is sleeved with an adaptive screw slider, and the outer wall of the screw slider is fixedly connected to the corresponding end of the seat ring;

[0010] In actual use, the patient sits on the seat ring, and starting the screw motor can drive the screw to rotate, thereby driving the screw slider to descend, thereby driving the seat ring to descend, allowing the patient to descend as well, so that the disposable medication tube can enter the patient's rectum.

[0011] As a preferred embodiment of the present invention, the outer wall of the disposable medication tube is sheathed with an annular tube, the inner wall of the annular tube is fixedly connected to a plurality of evenly distributed nozzles, a second box is fixedly installed on the other side of the inner cavity of the box, a second liquid pump is fixedly installed on the top of the second box, one end of the second liquid pump is connected to the second box, and the other end of the second liquid pump passes through the second box through a second hose and is connected to the annular tube;

[0012] Before the patient takes the medicine, starting the second liquid pump can extract the lubricant in the second box and introduce it into the annular tube, and then use the nozzle to spray it onto the outer wall of the disposable medication tube to lubricate it, so that the disposable medication tube can have a lubricating effect when entering the rectum, thereby reducing friction and reducing the patient's pain.

[0013] As a preferred embodiment of the present invention, a limiting slot is provided in the middle of one side wall of the box corresponding to the disposable medication tube, an adaptive limiting slider is inserted into the inner cavity of the limiting slot, a first electric push rod is fixedly connected to the top of the limiting slider, an outer end of the first electric push rod is fixedly connected to the inner wall of the limiting slot, a connecting rod is fixedly connected to the outer wall of the limiting slider, and the outer end of the connecting rod is fixedly connected to the outer wall of the annular tube;

[0014] When the annular tube is used to spray lubricating oil on the outer wall of the disposable medication tube, starting the electric push rod can drive the limit slider to slide in the limit slide groove, thereby driving the annular tube to rise and fall, thereby lubricating the disposable medication tube in all directions, improving the lubrication effect, and ensuring the thoroughness of lubrication.

[0015] As a preferred embodiment of the present invention, a second electric push rod is embedded in the corresponding seat rings on both sides of the top of the base, and the outer end of the push rod of the second electric push rod is fixedly connected to a pressure switch, and the pressure switch and the screw motor are electrically connected. During actual use, when it is necessary to limit the drug delivery depth of the patient, the electric push rod is started to drive the pressure switch to rise and fall, thereby adjusting the limit position of the seat ring by the pressure switch, so that when the disposable drug delivery tube enters the rectum, the seat ring descends. After descending to a certain position, pressure is applied to the pressure switch, so that the pressure switch turns off the screw motor, stopping the seat ring from descending, thereby being able to accurately control the drug delivery depth and ensure the accuracy of drug delivery.

[0016] As a preferred embodiment of the present invention, one side wall of the base is fixedly connected to a drain valve, and the setting of the drain valve can drain the sewage of the mobile phone.

[0018] As a preferred embodiment of the present invention, doors are hinged on both sides of one side wall of the box body. The arrangement of the doors enables the equipment inside the box to be protected.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The digestive tract rectal medical drug delivery device of the present invention sits on the seat ring when delivering medicine, and then uses the screw motor to drive the screw to rotate, thereby driving the screw slider to descend, and then the seat ring to descend, so that the disposable drug delivery tube can slowly enter the rectum. Compared with the previous drug delivery device, the present invention is simple to operate, effectively avoids the spatial obstacles of the previous autonomous operation, improves the operational convenience, and ensures accurate drug delivery. In addition, the groove on the top of the base can receive dripping medicine, thereby avoiding secondary contamination.

[0021] The annular tube can be raised and lowered by an electric push rod, and lubricating liquid can be pumped into the annular tube by a second liquid pump, and then sprayed onto the outer wall of the disposable drug delivery tube by a nozzle on the inner wall of the annular tube, so as to lubricate the drug before delivery, thereby reducing friction when inserting the drug into the rectum, thereby reducing the pain of the patient during use and improving the use effect;

[0022] During the medicine delivery process, the electric push rod can be used to drive the pressure switch to rise, so that the seat ring can be limited. When the seat ring is lowered, the disposable medicine delivery tube enters the rectum. When the pressure switch is triggered, the screw motor can be automatically stopped, so that the position of the disposable medicine delivery tube inserted into the rectum can be accurately controlled, thereby ensuring the accuracy of the medicine delivery position, further improving the accuracy of medicine delivery, and improving the treatment effect.

[0035] See also Figure 1-5The present invention provides a technical solution: a digestive tract rectal medical applicator, comprising a base 1, a groove 11 being formed on the top of the base 1, a hollow disk 12 being fixedly connected to the inner wall of the groove 11 via a fixing rod, a disposable drug delivery tube 13 being vertically connected to the top of the hollow disk 12, a plurality of evenly distributed holes 14 being formed on the top of the disposable drug delivery tube 13, a box 2 being fixed to one side of the base 1, a seat ring 21 being connected to a side wall of the box 2 adjacent to the disposable drug delivery tube 13;

[0036] In actual use, the patient sits on the seat 21, and then the seat 21 rises and falls, so that the disposable medication tube 13 enters the rectum to administer the medication. At the same time, during the medication process, if dripping occurs, the dripping liquid can be collected by the groove 11, thereby avoiding secondary contamination.

[0037] Furthermore, a drain valve 17 is fixedly connected to one side wall of the base 1. The drain valve 17 is configured to drain the wastewater from the mobile phone.

[0038] Furthermore, an adaptive sponge pad is fixedly installed on the top of the seat ring 21. The provision of the sponge pad can improve the comfort of the user;

[0039] like Figure 1 and 3 As shown; a first box body 3 is fixedly installed on one side of the inner cavity of the box body 2, and a first liquid pump 31 is fixedly installed on the top of the first box body 3. One end of the first liquid pump 31 is connected to the first box body 3, and the other end of the first liquid pump 31 passes through the box body 2 through a first hose and is connected to the hollow disk 12;

[0040] When delivering medicine into the rectum using the disposable medication tube 13, the first liquid pump 31 is activated to extract the medicine in the first box 3, so that the medicine is introduced into the disposable medication tube 13 and then into the digestive tract along the hole 14 for administration.

[0041] Furthermore, both sides of one side wall of the box body 2 are hinged with box doors, and the arrangement of the box doors enables the equipment in the box body 2 to be protected;

[0042] like Figure 1 and 2 As shown; a slide groove 22 is provided on both sides of a side wall of the box body 2 close to the seat ring 21, and a screw motor 23 is fixedly installed on the top of the inner cavity of the slide groove 22. The outer end of the transmission shaft of the screw motor 23 is fixedly connected to a screw rod 24. The outer end of the screw rod 24 is rotatably connected to the bottom of the inner cavity of the slide groove 22. The outer wall of the screw rod 24 is covered with an adaptive screw slider 25. The outer wall of the screw slider 25 is fixedly connected to the corresponding end of the seat ring 21;

[0043] In actual use, the patient sits on the seat 21 and starts the screw motor 23 to drive the screw 24 to rotate, thereby driving the screw slider 25 to descend, thereby driving the seat 21 to descend, so that the patient descends with it, so that the disposable medication tube 13 can enter the patient's rectum;

[0044] like Figure 1 and 2 , 3; the outer wall of the disposable dosing tube 13 is sheathed with an annular tube 15, the inner wall of the annular tube 15 is fixedly connected to a plurality of evenly distributed nozzles 18, the other side of the inner cavity of the box body 2 is fixedly mounted with a second box body 4, the top of the second box body 4 is fixedly mounted with a second liquid pump 41, one end of the second liquid pump 41 is connected to the second box body 4, and the other end of the second liquid pump 41 passes through the second box body 4 through a second hose and is connected to the annular tube 15;

[0045] Before the patient takes the medicine, the second liquid pump 41 is activated to extract the lubricant in the second box 4 and introduce it into the annular tube 15. Then, the nozzle 18 is used to spray the outer wall of the disposable medication tube 13, thereby achieving lubrication. This allows the disposable medication tube 13 to have a lubricating effect when entering the rectum, thereby reducing friction and alleviating the patient's pain.

[0046] Furthermore, a limiting chute 26 is provided in the middle of one side wall of the box body 2 corresponding to the disposable medication tube 13, and an adapted limiting slider 27 is inserted into the inner cavity of the limiting chute 26. A first electric push rod 28 is fixedly connected to the top of the limiting slider 27. The outer end of the first electric push rod 28 is fixedly connected to the inner wall of the limiting chute 26. The outer wall of the limiting slider 27 is fixedly connected to the connecting rod 16. The outer end of the connecting rod 16 is fixedly connected to the outer wall of the annular tube 15.

[0047] When the annular tube 15 is used to spray lubricating oil on the outer wall of the disposable medication tube 13, starting the electric push rod 28 can drive the limiting slider 27 to slide in the limiting slide groove 26, thereby driving the annular tube 15 to rise and fall, thereby lubricating the disposable medication tube 13 in all directions, improving the lubrication effect, and ensuring thorough lubrication;

[0048] like Figure 1 and 5As shown; second electric push rods 5 are embedded in the corresponding seat rings 21 on both sides of the top of the base 1, and the outer ends of the push rods of the second electric push rods 5 are fixedly connected to the pressure switch 51, and the pressure switch 51 is electrically connected to the screw motor 23. In actual use, when it is necessary to limit the depth of drug delivery to the patient, the electric push rod 5 is started to drive the pressure switch 51 to rise and fall, thereby adjusting the limit position of the pressure switch 51 on the seat ring 21, so that when the disposable drug delivery tube 13 enters the rectum, the seat ring 21 descends. After descending to a certain position, pressure is applied to the pressure switch 51, so that the pressure switch 51 turns off the screw motor 23, so that it stops driving the seat ring 21 to descend, thereby being able to accurately control the drug delivery depth and ensure the accuracy of drug delivery.

[0049] The implementation principle of the digestive tract rectal medical drug delivery device of the present application is: when in use, first, according to the required drug delivery depth, start the second electric push rod 5 to drive the pressure switch 51 to rise and fall, thereby adjusting the limit position of the pressure switch 51 on the seat ring 21, and use the measuring ruler to accurately measure the limit size, and then start the second liquid pump 41 to extract the lubricant in the second box 4 and introduce it into the annular tube 15, and then use the nozzle 18 to spray it to the outer wall of the disposable drug delivery tube 13, so as to achieve lubrication, and then make the disposable drug delivery tube 13 have a lubricating effect when entering the rectum, thereby reducing friction and reducing the patient's pain. When the annular tube 15 is used to spray lubricating oil on the outer wall of the disposable drug delivery tube 13, starting the first electric push rod 28 can drive the limit slider 27 to move on the limit slider. The disposable medication tube 13 is lubricated in an all-round manner, thereby improving the lubrication effect and ensuring the thoroughness of the lubrication. Then, the screw motor 23 is started to drive the screw 24 to rotate, thereby driving the screw slider 25 to descend, thereby driving the seat ring 21 to descend, so that the patient descends, so that the disposable medication tube 13 can enter the patient's rectum. Starting the first liquid pump 31 can extract the medicine in the first box 3, thereby introducing it into the disposable medication tube 13, and then introducing it into the digestive tract along the hole 14 for medication. During the medication process, if dripping occurs, the liquid can enter the groove 11 and be collected, thereby avoiding secondary contamination caused by dripping.
