Abstract
This utility model rectal suppository injection device, relate to a kind of device for rectally, by suppository storehouse, pusher and handle composition, pusher is by sleeve, pushing ram, push-and-pull cylinder, two connecting rods and two fixed axis compositions, the pusher of this novel employing is reverse force application apparatus, when namely needing injection suppository, force person needs pull handle, make the force direction of the force of force person's fixed muffle and pull handle contrary, the further propelling of sleeve can not be caused to cause darker misery to patient, the air in sleeve is utilized to arrange outward, when avoiding injection device to take out, the formation in negative pressure district, thus avoid the rollback of suppository.
Description
Technical field
This utility model relates to medical apparatus and instruments, particularly a kind of device for rectally.
Background technology
Rectal suppository is for a kind of a kind of solid chemicals for directly putting into rectum, because its effective ingredient melts at internal rectum, drug dose contained in rectal suppository is absorbed to treat local or the whole body of patient by the mucosa inwall of rectum, therefore some certain drug can be avoided the situation of inactivation to occur in stomach or liver, thus its dispensing toleration is good, be particularly suitable for vomiturition, chronic disease and gastroenteropathy etc. cannot oral medicine patient use, and the child that immunity is slightly poor, the patient that old man and impotentia take care of number one, also rectal suppository can be adopted to carry out the treatment of some diseases.
Current China, the input of rectal suppository is still based on freehand manner, existing suppository syringe mostly is the simple and easy improvement of ordinary syringe, be generally and place suppository on syringe top, syringe cylinder is put into rectum assigned address, promote push rod and suppository is pushed away syringe, send internal rectum to, in actual use, after syringe puts rectum assigned address into, because general suppository outward all can with fixing capsule, when promoting push rod, often need by larger power, now syringe cylinder is often under catch bar or operator hand firmly act on, move to internal rectum further, deepen patient suffering, and, in the process of extracting syringe, the formation of rectum negative pressuren zone, can make to have thrown in the suppository put in place to offset to rectum mouth, while reducing medication effect, increase the misery of medication patient again, simultaneously, the patient of some economic condition differences tends to reuse syringe, in existing syringe use procedure, suppository will pass whole syringe, even if often also there is very Davidson, James Wheeler hidden danger in sterilization.
summary of the invention:
The purpose of this utility model is to overcome above-mentioned technological deficiency, provides a kind of rectal suppository injection device with oppositely force pusher, suppository can be prevented to rectum mouth rollback simultaneously, ensure medication effect, thus significantly can reduce the misery of user.
This utility model is by suppository storehouse, pusher and handle composition, pusher is by sleeve, pushing ram, push-and-pull cylinder, two connecting rods and two fixed axis compositions, wherein handle is fixedly connected on the suppository storehouse far away end of push-and-pull cylinder, push-and-pull cylinder can be exerted a force by handle and do push-and-pull campaign in sleeve, two connecting rods are fixedly connected with push-and-pull cylinder inwall, and through sleeve lining, the fixed axis being fixed on sleeve lining with two is slidably connected, and form a free end through pushing ram, along connecting rod from sleeve lining to free end direction, the hole slot that three apertures and the degree of depth increase successively is provided with respectively at the both sides outer wall of sleeve lining and pushing ram, elastic rubber fitting is provided with between the hole slot of free end far away and connecting rod on sleeve lining and on pushing ram.Sleeve top central opening, sleeve top can level, also can be inversed taper platform shape, to adapt to the suppository with different polycrystalline substance.
In use, suppository storehouse is opening up, first suppository is put into suppository storehouse by opening head, pull handle gently, the gas fraction of barrel bore is made to enter in the interbed of sleeve, thus be beneficial to suppository fixing in suppository storehouse, then injection device is inserted rectum assigned address, continue pull handle again, make pushing ram enter suppository storehouse, suppository is injected internal rectum, limit pushes taking out injection device on hand again, air in cylindrical shell is arranged by outside suppository storehouse, avoids the formation of negative pressuren zone, cause suppository rollback.Wherein, in order to ensure that pull handle is excessive for the first time, causes pushing ram to enter suppository storehouse in advance, can be that push-and-pull cylinder arranges two pull gears and a propelling gear at sleeve outer wall.
As can be seen from above-mentioned novel technical scheme with use step, this is novel has following beneficial effect:
1. the pusher of a novel employing is reverse force application apparatus, when namely needing injection suppository, force person needs pull handle, makes the force direction of the force of force person's fixed muffle and pull handle contrary, the further propelling of sleeve can not be caused to cause darker misery to patient.
2. adopt the gas volume change in sleeve, control the fixing of suppository to a certain extent.
3. utilize the air in sleeve to arrange outward, when avoiding injection device to take out, the formation in negative pressure district, thus the rollback avoiding suppository.
In addition, this novel suppository settles head also according to used suppository shape difference, can be designed to correspondingly-shaped thus be designed to suppository syringe targetedly, such as can be designed to bullet type, shuttle-type etc.
accompanying drawing illustrates:
Fig. 1 is the structural representation of this utility model embodiment 1.
Detailed description of the invention
By reference to the accompanying drawings this utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with this utility model, can not be interpreted as the restriction to this utility model embodiment.
Embodiment 1
The rectal suppository injection device structure that this utility model provides as shown in Figure 1, comprise suppository storehouse 1, pusher 2 and handle 3, pusher 2 is by sleeve 20, pushing ram 22, push-and-pull cylinder 21, two connecting rods 23 and two fixed axis 24 form, wherein handle 3 is fixedly connected on the suppository storehouse 1 far away end of push-and-pull cylinder 21, push-and-pull cylinder 21 can be exerted a force by handle 3 and do push-and-pull campaign in sleeve 20, two connecting rods 23 are fixedly connected with push-and-pull cylinder 21 inwall, and through sleeve 20 inwall, the fixed axis 24 being fixed on sleeve lining with two is slidably connected, and form a free end through pushing ram 22, along connecting rod 23 from sleeve 20 inwall to free end direction, the hole slot 220 that three apertures and the degree of depth increase successively is provided with respectively at the both sides outer wall of sleeve 20 inwall and pushing ram 22, elastic rubber fitting is provided with between the hole slot 220 of free end far away and connecting rod on sleeve 20 inwall and on pushing ram 22.Sleeve 20 upper horizontal, central opening.
In use, suppository storehouse 1 is opening up, first suppository is put into suppository storehouse 1 by opening head, gently pull handle 3, make suppository at suppository storehouse 1 internal fixtion, then injection device is inserted rectum assigned address, then continue pull handle 3, suppository is injected internal rectum, limit pushes handle 3 limit and takes out injection device again, make the air in injection device by the outer row in suppository storehouse 1, avoid the formation of negative pressuren zone, cause suppository rollback.
