Description
Technical field
This utility model relates to defecation assisting fixture fields, particularly the unidirectional drug injecting device of a kind of controllable type.
Background technology
The cathartic such as glycerin and enema,glycerin class OTC (over-the-counter), has the effect of loosening bowel to relieve constipation, is current clinical conventional defecation assisting medicine.Glycerin application is convenient, cheap, but capacity is little, and ascending pipe length is short, and after injecting, medicine does not reach deep rectum; Medicinal liquid distance anus too closely and easily flows out external; And enema injecting pipe is comparatively hard, there are some researches show improper damage and the ulcer easily causing rectum anal tube of method using glycerin.Although enema,glycerin capacity is large, inject pipe range, matter is softer, head end is round and smooth, not easily damage rectal tissue, effect is more desirable than glycerin, but is coloclysis specification packaging because of it, action need has certain technical requirement, and in operator's improper use intestinal, feces residue resorption enters in enema to there is contamination phenomenon; Again because its cost of use is high, capacity is excessive, and patient once cannots be used up, and causes waste, and patient compliance is poor, so be not used widely in clinical nursing activity.
Domesticly at present there is no comparatively ideal Therapeutic Method to chronic constipation, most of patients still relies on glycerin for a long time after leaving hospital or enema,glycerin assists defecation.Many clinicians and nursing staff have carried out many-sided improvement to glycerin using method, wish the familiar lacunas solving traditional glycerin.
Method one is that glycerin is injected rectum or sigmoid colon by catheter or sputum aspirator tube: patient gets left lateral position, catheter or sputum aspirator tube tail end is connected with syringe, sucking-off glycerin inner liquid medicine, inserts rectum by soft after catheter proximal end lubrication along anus.
Method two is by glycerin and saline proportioning coloclysis: glycerin is added warm saline, transfusion device is communicated with by transfusion, cut the small filter of transfusion device end, be connected with transfusion device with disposal urinary catheter, gas in discharge pipe, with the front end of remaining glycerin lubrication disposal urinary catheter, then insert rectum.
But above two kinds of complicated operations of improving one's methods, must be completed by nursing staff, patient and family members operate inconvenience and should not accept.
In sum, there is following shortcoming in prior art:
1) the little 20ml of glycerin capacity, the short 4cm of ascending pipe length, after injecting, medicine does not reach deep rectum; Medicinal liquid distance anus too closely and easily flows out external; Enema injecting pipe is comparatively hard, there are some researches show improper damage and the ulcer easily causing rectum anal tube of method using glycerin.
2) although the large 110ml of enema,glycerin capacity, inject pipe range 12cm, matter is softer, and head end is round and smooth, not easily damage rectal tissue; But because of cost of use high 12 yuan/, specification bale capacity is excessive, waste is caused in using, action need has certain technical requirement, in operator's improper use intestinal, feces residue resorption enters in enema to there is pollution, the medicinal liquid polluted cannot reuse, and also cause waste, therefore patient compliance is poor.
In sum, a kind of portable pliable and tough smooth defecation assisting utensil simple to operate is provided, becomes those skilled in the art's problem demanding prompt solution.
The information being disclosed in this background of invention technology part is only intended to deepen the understanding to general background technology of the present utility model, and should not be regarded as admitting or imply in any form that this information structure has been prior art known in those skilled in the art.
