Embodiment 1

[0032] refer to Figure 1-6 , a hand-held drug delivery device for the anorectal department, comprising a drug storage cylinder 1 and a push-pull rod 2, a piston plate 3 is fixedly mounted on the top of the push-pull rod 2, and the piston plate 3 can reciprocate and slide airtightly along the inner side wall of the drug storage cylinder 1, The drug storage tube 1 is used for temporary storage of drugs, and the top of the drug storage tube 1 is threadedly connected with a drug delivery tube 4 for delivering drugs. The top of the drug delivery tube 4 is integrally formed with a drug delivery head 5. The cross-section is set as a trapezoidal structure, which is convenient for applying the medicine to the patient's diseased part, and the lower end of the dosing head 5 is threadedly connected with a lubricating guide mechanism 6, and the outer wall of the medicine storage cylinder 1 is integrally formed with symmetrically distributed finger rings 7, A locking mechanism 8 is fixedly...

Embodiment 2

[0037] Such as figure 1 and Figure 4 As shown, the present embodiment is basically the same as Embodiment 1. Preferably, the pushing mechanism 9 includes a driving box 901 fixedly installed on the outer wall of the drug storage cartridge 1, a power switch is installed on the top of the driving box 901, and the inside of the driving box 901 A drive motor 902 is fixedly installed, and a support frame 903 is fixedly installed inside the drive box 901. A drive wheel 904 is rotatably installed on the support frame 903. A rotating shaft is fixedly installed in the inner cavity of the drive wheel 904, and the rotating shaft passes through a coupling It is fixedly connected with the output end of the driving motor 902, and the drive wheel 904 passes through the bar-shaped hole on the drug storage tube 1 and is engaged with a rack 905. The rack 905 and the push-pull rod 2 are integrally formed.

[0038] In this embodiment, when the liquid medicine is applied to the sick part of the p...

Embodiment 3

[0040] Such as figure 1 and figure 2 As shown, this embodiment is basically the same as Embodiment 1. Preferably, a gear ring 10 is integrally formed on the outer wall of the drug delivery tube 4 .

[0041] In this embodiment, by setting the gear ring 10, the frictional force can be increased, which is convenient for the operator to disassemble and install the drug delivery tube 4, and improves the drug delivery efficiency.

Abstract

Disclosed is a handheld drug delivery device for an anorectal department. The device comprises a drug storage cylinder and a push-pull rod, a piston plate is fixedly installed at the top of the push-pull rod and can slide in an airtight reciprocating mode along the inner side wall of the drug storage cylinder, a drug delivery pipe is connected to the top of the drug storage cylinder in a threaded mode, and a drug delivery head is integrally formed at the top of the drug delivery pipe; the cross section of the drug delivery head is of a trapezoidal structure, the lower end of the drug delivery head is in threaded connection with a lubricating guide mechanism, symmetrically-distributed finger rings are integrally formed on the outer side wall of the drug storage cylinder, and a locking mechanism is fixedly installed in each finger ring; a pushing mechanism used for driving the push-pull rod to move stably at a constant speed is fixedly installed on the drug storage cylinder. The device can effectively prevent secondary injury to a patient in a drug delivery process, can apply drugs at a constant speed, improves the drug applying effect, further has the advantages of being convenient to disassemble and assemble, wide in application range and the like, is high in practicability, and meets the use requirements of different patients.

Description

technical field [0001] The invention relates to the technical field of anorectal nursing equipment, in particular to a hand-held drug delivery device for anorectal department. Background technique [0002] The anorectal department is mainly responsible for the treatment of diseases in the posterior gastrointestinal tract and anal area. Anorectal diseases are very common diseases in people. In clinical treatment of anorectal diseases such as hemorrhoids, hemorrhoid suppositories or externally applied medicines are usually sent into the intestines with drug delivery devices. It is a drug delivery method that is rapidly absorbed through the rectal mucosa and enters the large circulation to exert drug effects to treat systemic or local diseases. [0003] After retrieval, the patent with application number 201922294922.9 discloses a hand-held drug delivery device for anorectal medicine, which includes a frame, a motor box, a cartridge and a handle, and one side of the outer surfa...
