[0001] The utility model relates to the technical field of anorectal medicine, in particular to a handheld medication device. Background Art

[0002] The anorectal department specializes in the treatment of constipation, anal fissures, anal fistulas, anal abscesses, anal stenosis, anal papillary hypertrophy, perianal eczema, mixed hemorrhoids, internal hemorrhoids, and external hemorrhoids. The department's research focuses on diseases occurring in the terminal digestive organs. When administering medication to anorectal patients, the outer wall of the medication tube fits tightly against the inner wall of the patient's anus and intestines, preventing sufficient space for the medication. This can affect the effectiveness of medication administration, and unabsorbed medication can easily be removed when the tube is removed, resulting in significant medication waste. Utility Model Content

[0003] The purpose of the utility model is to solve the shortcomings of the prior art that the drug delivery tube is tightly fitted to the inner wall of the patient's anus and rectum and cannot provide enough space for the drug solution, which affects the drug delivery effect, and to propose a handheld drug delivery device.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A handheld drug delivery device is designed, including a drug-loading tube, a piston movably provided inside the drug-loading tube, a bolt rod fixedly installed on the end of the piston, a delivery tube sleeved on the end of the drug-loading tube, a cover plate connected to the end of the delivery tube, a check valve fixedly installed inside the cover plate, a drug delivery tube sleeved on the surface of the cover plate away from the delivery tube, drug delivery holes evenly opened on the surface of the drug delivery tube, a protective ring fixedly installed on the outer surface of the drug delivery tube, and a reserved groove opened inside the protective ring.

[0018] 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 the embodiments.

[0019] Example 1: Reference Figure 1-4A handheld drug delivery device includes a drug-loading tube 1. A transparent window with a uniformly scaled surface is fixedly mounted on one side of the drug-loading tube 1. The changes in the liquid level of the drug solution inside the drug-loading tube 1 can be observed through the transparent window. A piston 3 is movably mounted inside the drug-loading tube 1. A bolt rod 2 is fixedly mounted on the end of the piston 3. Pulling the bolt rod 2 can drive the piston 3 to move inside the drug-loading tube 1, thereby squeezing out the drug solution. The amount of squeezed drug solution can be controlled according to the scale. A delivery tube 4 is sleeved on the end of the drug-loading tube 1. The delivery tube 4 is a hose. A cover plate 5 is connected to the end of the delivery tube 4. The cover plate 5 can control the degree to which the drug delivery tube 7 enters the human anus and intestines, allowing the drug delivery tube 7 to fully enter the human anus and intestines and preventing the drug delivery tube 7 from excessively entering the human anus and intestines, making the operation more convenient and safer.

[0020] A check valve 9 is fixedly installed inside the cover plate 5. The check valve 9 allows the liquid medicine inside the delivery tube 4 to enter the drug delivery tube 7, but the liquid medicine inside the drug delivery tube 7 cannot enter the delivery tube 4, which can prevent the liquid medicine inside the drug delivery tube 7 from flowing back and contaminating the liquid medicine inside the delivery tube 4. The surface of the cover plate 5 away from the delivery tube 4 is provided with a drug delivery tube 7, which extends to the inside of the anus and intestines of the human body. When the drug delivery tube 7 completely enters the anus and intestines of the human body, the cover plate 5 fits against the buttocks of the human body. Drug delivery holes are evenly opened on the surface of the drug delivery tube 7, and the liquid medicine inside the drug delivery tube 7 can be delivered into the patient's body through the drug delivery holes.

[0021] A protective ring 8 is fixedly mounted on the outer surface of the dosing tube 7. The diameter of the protective ring 8 is larger than the diameter of the dosing tube 7. The inside of the protective ring 8 is made of silicone and has a certain degree of softness, but it will not deform significantly. The protective ring 8 will not cause harm to the human body while providing sufficient support. When the dosing tube 7 is located inside the human anus and intestines, the protective ring 8 can prop up the inner wall of the human anus and intestines, leaving a gap between the surface of the dosing tube 7 and the inner wall of the anus and intestines, allowing the liquid medicine to easily enter the anus and intestines. A reserved groove 81 is provided inside the protective ring 8. There is at least one pair of reserved grooves 81 and they are distributed in a circular array around the dosing tube 7. When the dosing tube 7 is taken out of the anus and intestines, if there is no reserved groove 81, the protective ring 8 will bring out the liquid medicine between the protective ring 8 and the dosing tube 7 that has not been absorbed in the future, resulting in a large amount of liquid medicine being wasted. The reserved groove 81 can provide space for the medicine liquid. When the protective ring 8 leaves the anus and intestines, the medicine liquid can remain in the anus and intestines through the reserved groove 81. Although some medicine liquid may still be brought out, the amount of medicine liquid brought out can be greatly reduced, and some medicine liquid that has not been absorbed can be retained, reducing waste.

[0022] The cover plate 5 is fixedly mounted with a clamping handle 13 on the surface on the same side as the delivery tube 4. The clamping handle 13 can be used to conveniently push the drug delivery tube 7 into the anus and rectum of the human body through the cover plate 5. The close distance between the clamping handle 13 and the cover plate 5 and the drug delivery tube 7 can more accurately control the force and speed of pushing and removing the drug delivery tube 7, thereby avoiding causing the patient to feel greater pain. In addition, the cover plate 5 is connected to the drug delivery tube 1 through the soft and flexible delivery tube 4, which has a good advantage: after holding the clamping handle 13 to push the drug delivery tube 7 into the anus and rectum of the human body through the cover plate 5, it is necessary to manually push the bolt rod 2 and the piston 3 to push the liquid medicine into the drug delivery tube 7. In the process, the bolt rod 2 and the drug delivery tube 1 will inevitably shake slightly. If the medical staff is not careful, it may cause the drug delivery tube 1 to shake significantly. The delivery tube 4 can prevent the drug delivery tube 1 from transmitting the shaking force to the drug delivery tube 7, thereby maintaining the stability of the drug delivery tube 7 and preventing the drug delivery tube 7 from shaking and separating from the human body or even causing harm to the human body.

[0023] The lower end of the cover plate 5 is fixedly mounted with an arc plate 6, and the lower end of the arc plate 6 is bent toward one side of the medication tube 7. When the cover plate 5 is in contact with the skin of the buttocks at the anus of the human body, the arc plate 6 will be in contact with the skin of the buttocks below the anus of the human body. The arc-shaped design allows the arc plate 6 to better adapt to the shape of the patient's buttocks. The upper end of the cover plate 5 and the lower end of the arc plate 6 are both fixedly mounted with anti-slip strips 12. The anti-slip strips 12 play a role in preventing slipping. When the cover plate 5 and the arc plate 6 are in contact with the patient's buttocks, the anti-slip strips 12 can prevent the cover plate 5 and the arc plate 6 from sliding and deflecting with the patient's legs, which can further improve the stability of the medication tube 7.

[0024] A collection box 10 is fixedly installed inside the arc plate 6, and an absorption block 11 is placed inside the collection box 10. The absorption block 11 is a water-absorbing sponge, and the absorption block 11 can be easily taken out and replaced from the inside of the collection box 10. When the drug delivery tube 7 is in the process of delivering the drug, if the drug solution leaks from the patient's anus, the drug solution will flow to the absorption block 11 and be absorbed by the absorption block 11, which can prevent the drug solution from flowing onto the bed. Since a patient may need to be given the drug multiple times, in order to save resources, the drug delivery tube 7 and the contaminated absorption block 11 can be thrown away separately, and the cover plate 5, the arc plate 6 and the inside of the collection box 10 can be disinfected and cleaned, so that they can be used by patients at the same time. Of course, the entire drug delivery device is made of ordinary medical materials, so even if it is replaced with a new one each time it is used, it does not cause a lot of waste.

[0025] Working principle: When using the handheld drug delivery device, inject the drug solution into the drug-loading tube 1, put the piston 3 and the bolt rod 2 into the drug-loading tube 1, hold the pressing handle 13 to drive the drug delivery tube 7 to move through the cover plate 5, push the drug delivery tube 7 into the patient's anus and intestine, and make the cover plate 5 and the arc plate 6 just fit the patient's buttocks to ensure that the position where the drug delivery tube 7 is pushed in will not deviate. Then push the bolt rod 2 by hand to drive the piston 3 to push the drug solution, and the drug solution will enter the drug delivery tube 7 through the delivery tube 4, and the drug solution will flow out through the drug delivery hole on the surface of the drug delivery tube 7. The protective ring 8 stretches the inner wall of the patient's anus and rectum, allowing the medicine to enter the gap between the dosing tube 7 and the inner wall surface of the anus and rectum. The medicine can contact the inner wall of the patient's anus and complete the medication. During this process, if the medicine leaks from the patient's anus, the leaked medicine will flow down along the arc plate 6. The absorption block 11 can absorb the flowing medicine, which can prevent the medicine from contaminating the bed. Finally, when the dosing tube 7 is taken out, the reserved groove 81 can provide space for the medicine that has not been completely absorbed, preventing the protective ring 8 from bringing out the unabsorbed medicine and causing great waste.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
