For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0030] Most of the existing anal medicine applicators are mainly handheld. When medical staff apply medicine to a patient's anus, they need to hold the medicine pusher and push the push rod to apply medicine to the patient's anus. During the medicine application process, when the medicine pusher is inserted into the patient's body, there will be a collision between the outside of the medicine pusher and the patient's anus, which is likely to cause secondary damage to the patient's anus, thereby aggravating the patient's injury and making the use effect of the anal medicine pusher not good enough.
[0031] In the related art, an anal medicine injector does not have good protection function. Generally, the injector is directly inserted into the patient's body, and the push rod is pushed to inject the medicine into the patient's anus to apply medicine to the patient's anus. During the use process, the outer side of the injector collides with the patient's anus, which is likely to cause secondary injury to the patient's anus, thus aggravating the patient's injury and making the use effect of the anal medicine injector not good enough.
[0032] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides an anal medicine injector. When it is necessary to apply medicine to the patient's anus, only need to first insert the medicine guiding tube 12 into the patient's anus, and squeeze the protective shell 21 through the patient's anus to generate pressure, so that the protective shell 21 slides outside the medicine guiding tube 12 and the medicine cylinder 11 while squeezing the first spring 26, so that the first spring 26 buffers the pressure generated by colliding with the patient's anus, realizing the buffering effect, avoiding direct rigid contact between the medicine cylinder 11 and the anus, causing secondary injury to the patient, and further achieving the effect of improving the protection performance of the anal medicine injector.
[0033] The present application will be described below with reference to the accompanying drawings and specific embodiments:
[0034] Combined with Figure 1 - Figure 4 The embodiment of the present application provides an anal medicine injector, including a medicine injection component 1. The medicine injection component 1 includes a medicine cylinder 11, the bottom of which is fixedly connected with a medicine guiding tube 12. A piston rod 13 is slidably connected to the medicine cylinder 11. A protection component 2 is arranged on the medicine cylinder 11. The protection component 2 includes a protective shell 21 slidably connected to the outside of the medicine cylinder 11 and the medicine guiding tube 12. An installation groove 22 is opened on the protective shell 21. A sliding groove 23 is opened on the protective shell 21. A slider 24 is slidably connected to the inside of the sliding groove 23. Both ends of a sliding rod 25 are fixedly connected to the medicine cylinder 11 and the slider 24 respectively. A first spring 26 is arranged inside the sliding groove 23, and both ends are fixedly connected to the protective shell 21 and the slider 24 respectively.
[0035] When in use, first place the drug inside the cartridge 11, and insert the piston rod 13 into the inside of the cartridge 11 and push it to a suitable position. Then, first insert the drug delivery tube 12 into the patient's anus, and apply pressure to the protective shell 21 by squeezing it through the patient's anus, so that while the protective shell 21 slides on the outer side walls of the drug delivery tube 12 and the cartridge 11, the cartridge 11 slides inside the installation groove 22. Furthermore, the first spring 26 fixedly connected to the protective shell 21 generates elastic support under the support of the slider 24 and the slide rod 25. Subsequently, the slider 24 and the slide rod 25 slide inside the chute 23, enabling the first spring 26 to buffer the pressure generated by hitting the patient's anus, achieving the buffering effect, avoiding direct rigid contact between the cartridge 11 and the anus and causing secondary harm to the patient, and thus achieving the function of improving the protective performance of the anal drug injector.
[0036] Specifically, the cartridge 11 and the drug delivery tube 12 are integrated, preferably a syringe with a syringe pusher, which has been fully disclosed and will not be elaborated here.
[0037] In some embodiments, the protection component 2 further includes: a push rod 27 fixedly connected to the piston rod 13, so that the drug inside the drug delivery tube 12 can be pushed out, avoiding excessive drug residue in the drug delivery tube and causing drug waste, and improving the use effect.
[0038] Specifically, the diameter of the push rod 27 is smaller than the inner diameter of the drug delivery tube 12, and it will not block the drug delivery tube 12 and prevent the drug from being pushed out. When the push rod 27 completely enters the drug delivery tube 12, the push rod 27 can push out all the drugs inside the drug delivery tube 12, avoiding drug waste caused by drug residue inside the cartridge 11, and the push rod 27 will not affect the drugs inside the cartridge 11.
[0039] In some embodiments, the protection component 2 further includes: a ring 28 fixedly connected to the cartridge 11. When administering the drug to the patient's anus, the user inserts the index finger and middle finger into the two rings 28, and presses the piston rod 13 with the thumb to pick up the drug injector, improving the picking-up stability of the drug injector.
[0040] Specifically, there are two rings 28, which are symmetrically arranged with the middle part of the cartridge 11 as the center, facilitating the insertion of the index finger and middle finger into the rings 28.
[0041] In some embodiments, a fixing component 3 is provided on the ring 28. The fixing component 3 includes a connecting rod 31 slidably connected to the ring 28, a fixing block 32 fixedly connected to the connecting rod 31, and a second spring 33 sleeved outside the connecting rod 31, with both ends fixedly connected to the ring 28 and the fixing block 32 respectively.
[0042] In use, first insert the index finger and middle finger into the two rings 28 respectively, and squeeze the fixed block 32 through the fingers, so that the fixed block 32 drives the connecting rod 31 to slide inside the ring 28. Furthermore, the second spring 33 fixedly connected to the ring 28 generates elastic support under the support of the ring 28, so that while the second spring 33 generates elastic force on the fixed block 32, the fixed block 32 fixes the fingers of the medical staff, achieving the effect of limiting, avoiding the harm caused to the patient by the separation of the applicator from the hand during the drug administration process, and further achieving the effect of improving the use effect of the anal syringe.
[0043] Specifically, the contact surfaces of the two fixed blocks 32 with the fingers are both arc-shaped, making them more fitting with the staff's hand and improving the use stability.
[0044] In some embodiments, the fixing assembly 3 further includes: a limiting block 34 fixedly connected to the connecting rod 31. By setting the limiting block 34, the connecting rod 31 can slide inside the ring 28 without detaching from the ring 28, improving the connection stability between the connecting rod 31 and the ring 28.
[0045] In some embodiments, both the medicine guiding tube 12 and the protective shell 21 have arc-shaped surfaces, which are respectively arranged at the bottom of the medicine guiding tube 12 and the contact part of the protective shell 21 with the anus, reducing the friction generated when the medicine guiding tube 12 and the protective shell 21 come into contact when entering the anus, avoiding causing discomfort to the patient, and further achieving the effect of improving the use comfort.
[0046] In some embodiments, the protective assembly 2 further includes: a medicine outlet hole 29 is opened on the outer side of the piston rod 13 and penetrates through the piston rod 13.
[0047] Specifically, the medicine outlet holes 29 are arranged in multiple numbers, and the multiple medicine outlet holes 29 are evenly distributed on the medicine guiding tube 12, facilitating the discharge of the liquid medicine, increasing the medicine application range, and the medicine outlet holes 29 are for single use, which can effectively avoid clinical cross-infection.
[0048] In some embodiments, the installation groove 22, the sliding groove 23, the sliding block 24, the sliding rod 25 and the first spring 26 are a group, and at least two groups are provided. By setting multiple installation grooves 22, sliding grooves 23, sliding blocks 24, sliding rods 25 and first springs 26, the multiple first springs 26 buffer the pressure generated by colliding with the patient's anus, further improving the protection effect.
