Description
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.
