[0020] 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.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 2, a drug delivery tool for convenient anal administration of ointments and gel dosage forms, including a safety ring 5 and a drug delivery cavity 6, the drug delivery cavity 6 is fixedly connected to the safety ring 5, the length of the drug delivery cavity 6 is the distance for safe drug delivery, when the drug delivery cavity 6 enters the anal canal, until the safety ring 5 contacts the end of the anal canal, the drug delivery cavity 6 can completely enter the anal canal, the safety ring 5 can hinder the drug delivery cavity 6 from entering the anal canal, avoid the drug delivery cavity 6 from entering too deep, can limit the distance between the drug delivery device and the anus, making the operation safer, a through groove is opened on the side of the drug delivery cavity 6, the through groove is convenient for the outflow of the medicine, a round hole is opened at one end of the through groove close to the safety ring 5, because the through groove is arranged in a long strip shape, the medicine is discharged into the through groove through the round hole from the placement tube 4 through the cylinder 7, and the medicine in the through groove can adhere to the inner wall of the anal canal, so as to achieve the effect of uniform drug coating inside the anal canal.

[0023] The medicine delivery cavity 6 is provided with mounting components, which include a delivery tube cylinder 7 and a placement cylinder 4. The cylinder 7 is fixedly connected to the safety ring 5. The interior of the cylinder 7 is hollow and communicated with the circular hole. A thread is provided on the outer surface of the cylinder 7. A thread is provided on the outer wall of one end of the placement cylinder 4. The placement cylinder 4 is threadedly connected to the inner wall of the cylinder 7 to facilitate installation and disassembly between the medicine delivery cavity 6 and the placement cylinder 4. The end of the medicine delivery cavity 6 away from the safety ring 5 is arc-shaped. The medicine delivery cavity 6 with an arc-shaped end is for safer and smoother entry into the anal canal. The mounting components also include a push rod 3, one end of which is slidably connected to the placement cylinder 4. The working distance between the push rod 3 and the placement cylinder 4 is the same as the syringe distance in the prior art.

[0024] The end of the push rod 3 away from the placement tube 4 is fixedly connected to the pressing plate 1. The push rod 3 is hollow and a one-way valve is installed at one end of the push rod 3. The gas inside the push rod 3 can be discharged, and external medicine cannot enter the push rod 3. The end of the push rod 3 away from the placement tube 4 is fixedly connected to the pressing plate 1.

[0025] The outer surface of the push rod 3 is fixedly connected to the airbag 2, one end of the airbag 2 is fixedly connected to the pressing plate 1, a connecting tube 9 is fixedly connected to the inner wall of the airbag 2, the connecting tube 9 is connected to the push rod 3, and a first spring 10 is fixedly connected between two opposite side walls in the airbag 2.

[0026] In the utility model, when in use, the medicine delivery cavity 6 is placed in the anal canal. When the medicine needs to be delivered to the anal canal, the push rod 3 is driven to move by pushing the pressing plate 1. The push rod 3 can squeeze the medicine in the placement tube 4 through the cylinder 7 and evenly discharge it to the inner wall of the anal canal through the medicine delivery cavity 6 for treatment. As the disc 8 and the pressing plate 1 move, the disc 8 can contact the placement tube 4. As the pressing plate 1 continues to move, the airbag 2 can be squeezed and the first spring 10 can be compressed. As the airbag 2 is compressed, the internal gas is transmitted to the push rod 3 through the connecting tube 9, and is transmitted to the placement tube 4 through the push rod 3. The medicine that the push rod 3 cannot squeeze is completely squeezed into the anal canal by the gas, thereby avoiding waste of medicine.
