Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a combined anorectal medication device. Background Art
[0002] Anorectal administration is mainly for rectal vein absorption. Due to the different structure of the rectal vein, the drug is absorbed faster, which can prevent gastric mucosal irritation symptoms caused by some oral drugs. It can generally be used for diseases such as fever, cough, diarrhea, upper respiratory tract infection and bacterial dysentery.
[0003] Application No. 202221462479.7 discloses an anorectal drug delivery device, which realizes the convenient disassembly of the drug delivery head through the cooperation of the drug delivery head, the clamping rod, the fixed sleeve rod, the reset spring and the push block, ensuring that only one insertion is required during the drug delivery process, avoiding discomfort to the patient due to multiple insertions. At the same time, by disassembling the drug delivery head, it can be replaced, greatly reducing the high replacement cost caused by the integrated design.
[0004] When installing the medicine head of the above application, the cooperation of the clamping rod, the fixed sleeve rod, the reset spring and the push block is required. The structure is relatively complicated and inconvenient to operate. After the medicine head is taken out of the body, its outer wall will be contaminated with intestinal substances. If it is not operated properly, it will easily come into contact with surrounding objects and cause contamination. Utility Model Content

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] See also Figures 1 to 4 The utility model provides a technical solution: a combined anorectal drug delivery device, including a drug delivery tube 1, a piston rod 2 is slidably connected inside the drug delivery tube 1, a drug outlet tube 3 is connected to one side of the drug delivery tube 1, an extension tube 4 is rotatably connected to one end of the drug outlet tube 3, a drug delivery head 5 is threadedly connected to one end of the extension tube 4, a plurality of drug delivery holes 6 are provided inside the drug delivery head 5, a scale value 16 is provided on the outside of the drug delivery head 5, and the length of the drug delivery head 5 entering the intestine is conveniently grasped, and the outer wall of the extension tube 4 and the inside of the drug delivery head 5 are respectively provided with mutually matching threads, and the threads are screwed in the inner wall of the extension tube 4. The threaded connection facilitates the fixation and separation of the drug delivery head 5 and the drug delivery structure, making the operation simpler. A positioning cover 10 is installed on the top of the drug delivery tube 1 and on the outside of the piston rod 2. A locking bolt 11 is threadedly connected to one side of the positioning cover 10. One end of the locking bolt 11 extends into the positioning cover 10, so that the locking bolt 11 rotates and displaces at the same time to clamp the piston rod 2 to prevent it from being accidentally touched, resulting in accidental extrusion of the drug. The outer wall of the drug delivery head 5 is connected to a protective cover 7. A drawstring 8 is installed inside one end of the protective cover 7. One end of the drawstring 8 The protective cover 7 is extended to the outside of the protective cover 7 so that the protective cover 7 can be unfolded to cover and wrap the drug delivery head 5. At the same time, one end of the protective cover 7 can be tightened by the drawstring 8 to seal it, so as to prevent the substances contaminated on the outer wall of the drug delivery head 5 from contacting the surroundings. A one-way valve 9 is installed inside the drug delivery head 5, which cooperates with the protective cover 7 to prevent the residual liquid medicine in the drug delivery head 5 from backflowing and dripping. The outside of the drug delivery tube 1 is wrapped with a heating pad 12, and a water cavity 13 is opened inside the heating pad 12. Under the action of the hot water in the water cavity 13, the drug delivery tube 1 and the liquid medicine therein are heated. Heat is beneficial to avoid the temperature of the medicine being too low and causing discomfort to the patient. A liquid inlet pipe 14 is connected to the top of the heating pad 12. One end of the liquid inlet pipe 14 extends into the water cavity 13. The other end of the liquid inlet pipe 14 is threadedly connected to a sealing cap 15. The liquid inlet pipe 14 facilitates the injection and discharge of hot water in the water cavity 13 and is sealed under the action of the sealing cap 15. The two ends of the heating pad 12 are respectively sewn with a Velcro fur surface and a Velcro thorn surface that match each other, so that the two ends of the heating pad 12 can be pasted together, which is convenient for the heating pad 12 to fix and remove the medicine delivery tube 1.
[0023] In summary, when the combined anorectal drug delivery device is used, the heating pad 12 is wrapped around the outside of the drug delivery tube 1, and the hot water in the water cavity 13 of the heating pad 12 is used to heat the liquid medicine in the drug delivery tube 1. Then, the extension tube 4 at one end of the drug outlet tube 3 on one side of the drug delivery tube 1 is inserted into the drug delivery head 5, and the extension tube 4 is rotated. The extension tube 4 and the drug delivery head 5 are threadedly connected to fix the extension tube 4 and the drug delivery head 5. At this time, according to the scale value 16 on the drug delivery head 5, the drug delivery head 5 is pushed to a certain length in the patient's intestine, and the piston rod 2 in the drug delivery tube 1 is pushed to squeeze the liquid medicine in the drug delivery tube 1 through the drug outlet tube 3 and the extension tube 4 into the drug delivery head 5. Then the medicine is squeezed out into the intestine through multiple drug outlet holes 6. At the same time, when the medicine is insufficient, the extension tube 4 can be rotated to separate it from the dosing head 5, and the extension tube 4 on the new drug delivery tube 1 filled with liquid medicine is aligned with the dosing head 5, and rotated again to fix it, and the operation is repeated to perform the drug delivery. After the end, the dosing head 5 is pulled out of the intestine, and the outer protective cover 7 of the dosing head 5 is unfolded to wrap the dosing head 5, and then the drawstring 8 at one end of the protective cover 7 is tightened to tighten one end of the protective cover 7 to close the dosing head 5. Similarly, according to needs, the extension tube 4 can be rotated again to separate the dosing head 5 from the drug delivery tube 1 and put into the corresponding medical waste container.
[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
