Description

Injection-type enema drug delivery device

Technical field

The utility model relates to medical instrument assistant product technical field, more particularly to a kind of suitable for constipation patient Enema drug delivery device.

Background technique

Enema enema fluid is generally contained in the plastics ball capsule of carrying pipe in the prior art, and capacity is 10~20ml, In use, then squeezing sacculus by nose catheter and neck insertion patient anus, medical fluid being squeezed into patient's body.

Rectum 12~15cm of overall length, anal canal are about 4cm, and defecation, exhaust reflection are completed by the nerve in ampullar recti portion, and straight Intestines ampulla is away from anus maximum distance about 7cm.Find during clinical use: existing enema catheter length is too short (generally 4cm or so), medical fluid, which is squeezed into after rectum, to be easy excessive, and stimulation is small, and exhaust, defecation reflex are weak, promotes the work of intestinal function recovery With also relatively weak；And the conduit of enema preparation is hard, plastics rubber shell cannot be squeezed sufficiently, and prevent medical fluid from all being squeezed Enter in rectum, conduit and neck meeting residual liquor lead to the waste of medical fluid；Simultaneously because an enema capacity be only 10~ 20ml is easy to cause mucosa injury, bleeding, gives so enema conduit must be inserted into anus repeatedly when needing usage amount big Patient brings pain.

In addition, due to medical fluid be all flowed out by the opening of catheter proximal end so that big medicine amount liquid moment from opening gush out into Enter in human body, it is very big to patient's stimulation, pain is brought to patient, since medical fluid concentrates at one, pulls out meeting after enema conduit It quickly spills out and causes to waste, the aperient effects after influencing administration.

Application No. is the utility applications of CN201520726686.2 to disclose a kind of pusher enema administration Device, including syringe and straight tube, the front end of syringe are connected with the rear end of straight tube, and the front end of straight tube is hemispherical, before straight tube Several medicine outlets are uniformly provided on end and front end tube wall, which can control the depth of straight tube insertion, but when administration, Medical fluid has residual in straight tube, and there are liquid wastes.

Application No. is the utility applications of CN201320371669.2 to disclose a kind of enema feeding device, this is opened Plug dew delivery device is the syringe that front end is fixed with silicone anal tube, is provided with scale on syringe and anal canal, the delivery device Irritation is small when with insertion anus, insertion depth and the controllable advantage of dosage；But the delivery device of above-mentioned patent is integrated Formula design, anal canal and syringe fixation be linked together, be it is disposable, the enema being not used in delivery device can not weigh It is multiple to use, it causes to waste, meanwhile, a medicine outlet is only arranged in anal canal front end, the aperient effects after influencing administration.

Utility model content

In view of the problems of the existing technology, the utility model provides a kind of injection-type enema drug delivery device Medical fluid is all efficiently used several times, reduces liquid waste, when can also reduce because of the same time using more enema Repeated intubation mitigates patient suffering, and aperient effects are good, safety and sanitation, easy to operate, time saving and energy saving.

In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of injection-type and open plug Reveal drug delivery device, including syringe and nose catheter, the syringe include cartridge, the first boosting mechanism and the second boosting machine Structure, the cartridge are located at the outside of first boosting mechanism；First boosting mechanism includes first piston, first piston Bar and first piston rod handle, one end of the First piston bar are inserted into the cartridge after installing first piston by cylinder cap, The other end connects with first piston rod handle；The nose catheter and the connector of the front end of the syringe are detachably connected.

Second boosting mechanism includes second piston, second piston bar and second piston rod handle, the First piston bar, The centre of first piston rod handle and first piston has a through hole to match with the second piston, the second piston One end of bar by first piston rod handle install second piston after is inserted into the through hole of first boosting mechanism, the other end with The second piston rod handle connects, and the end of the second piston and the end of the first piston match, described first Under the drive of boosting mechanism and second boosting mechanism second piston can extend into the nose catheter will be described before It holds in conduit in remaining medical fluid push-in human body.

In order to solve the above technical problems, the further technical solution that the utility model uses is:

It further include pipe cap, the pipe cap is placed on the front of the connector.

It further says, the end of the front end of the nose catheter is open with drug, and pipe is run through with multiple in front The medicine outlet hole of wall, the diameter of the drug opening are 0.4-0.6cm, and the aperture of the medicine outlet hole is 0.2-0.3mm.

It further says, the medicine outlet hole is distributed in the leading flank apart from the nose catheter as in the range of 1-2cm.

It further says, realizes the mode that the connector of the front end of the nose catheter and the syringe is detachably connected Are as follows: grafting or threaded connection.
