Abstract
The utility model discloses a disposable painless medical catheter kit; for a patient with the need of using a catheter, the catheter can produce the stimulating effects on urethra mucosa and bladder mucosa during the processes of inserting the catheter or retaining the catheter for catheterization, thereby ensuring the patient to have the emiction sense frequently, irritating the mood of the patient and affecting the treatment, the utility model provides the disposable painless medical catheter kit which is composed of a pre-injection tube (1) and the catheter (2) for solving the problems, the pre-injection tube (1) pre-injects local anesthetics to the urethra mucosa and the bladder mucosa before the insertion into the catheter (2), thereby alleviating the discomfort of the patient during the insertion into the catheter (2); the surface anesthesia is implemented to the urethra mucosa and the bladder mucosa after the intubation of the catheter (2), thereby leading the patient to have the relatively comfortable tolerance; the anesthetics is intermittently injected to an anesthetic injection pipeline (4) according to the personal difference of the patient and the requirements, thereby alleviating the suffering of the patient after the insertion of the catheter and being very conductive to the treatment of the patient and the physical health.
Description
Technical field
This utility model belongs to the medical appliance field, is specifically related to a kind of medical catheter.
Background technology
In clinical, for patient with operation, the interim patient who places catheter, needing to use catheter is its urethral catheterization, to guarantee operation, anesthesia is carried out smoothly, in the process of inserting catheter and the urethral catheterization of retention catheterization pipe, catheter can produce stimulation to mucous membrane of urethra and mucous membrane of urinary bladder, makes patient that micturition desire frequently be arranged, thus the mood agitation, the influence treatment, and can cause other complication, speed, hypertension etc. as heart rate, particularly to urinary tract infection is arranged, the urethra cicatrix, urethral stricture, psychentonia, prostatitis, the patient of prostatic hyperplasia, insert the special pain of catheter meeting, anxiety causes muscle contraction, causes catheter and inserts difficulty.For addressing this problem, medical circle has also been done number of research projects, as the patent No. is that the Chinese patent of CN99254909.4 discloses a kind of Foley catheter with the numb function of table, this catheter is established a microtubule in former urethral catheterization tube wall, establish several local anesthetic ejection holes at its front end, be opened on outside the urethral catheterization tube wall.Because catheter will guarantee that urine flows out smoothly, diameter is bigger, can make patient feel pain during insertion; And the spray-hole of this catheter is the single urethral catheterization tube wall front end that is arranged in, and exists the one side that do not have spray-hole and leading portion urethra local anaesthetics to be difficult to the problem that mucous membrane of urethra and mucous membrane of urinary bladder are anaesthetized, and patient can feel local discomfort.
Summary of the invention
For addressing the above problem, this utility model aims to provide a kind of disposal indolence catheter external member for medical purpose, and this catheter external member is easy to use, can alleviate the sense of discomfort of patient when inserting catheter greatly, and tolerance catheter that can be pleasant after intubate.
This utility model is achieved through the following technical solutions: disposal indolence catheter external member for medical purpose is made up of pre-notes pipe and catheter, the pre-pipe of annotating can be annotated local anaesthetics to mucous membrane of urethra and mucous membrane of urinary bladder in advance before plugging in catheter, can alleviate the sense of discomfort of patient when inserting catheter, catheter is used for urethral catheterization and after intubate mucous membrane of urethra and mucous membrane of urinary bladder is implemented topical anesthesia, makes the tolerance catheter that patient can be pleasant.
Pre-notes pipe is an elongated tubular, establishes several local anesthetic ejection holes in the length range that inserts the human body urethra, and this segment length can be according to adult, child, man, woman's different designs; There is valve at the rear tab place, syringe can be annotated anaesthetic by valve in pre-notes pipe tube chamber, because pre-notes pipe is an elongated tubular, diameter is little, little during insertion to the stimulation of patient's mucous membrane of urethra and mucous membrane of urinary bladder, take out behind the intact anaesthetic to be injected, because the effect of anaesthetic has been arranged, the sense of discomfort of patient when inserting catheter can be alleviated, successful intubation can be improved the especial patient of urinary tract infection, urethra cicatrix, urethral stricture, psychentonia, prostatitis, prostatic hyperplasia.
Catheter flows out pipeline, water pocket flow in pipes, anaesthetic flow in pipes by urine to be formed, several local anesthetic ejection holes are set on the anaesthetic flow in pipes, all there is valve at the rear tab place of water pocket flow in pipes and anaesthetic flow in pipes, syringe can be annotated anaesthetic by valve water filling in the water pocket of water pocket flow in pipes in the tube chamber of anaesthetic flow in pipes; The anaesthetic flow in pipes is microtubule that is used to spray local anaesthetics of design in the wall of catheter, and on this pipeline, tell another local anaesthetics isocon that on circumference, is symmetrically distributed with it, establish several local anesthetic ejection holes in the length range of anaesthetic flow in pipes and local anaesthetics isocon insertion human body urethra, this segment length can be according to adult, child, man, woman's different designs; Because local anesthetic ejection hole is symmetrically distributed in the circumference both sides, medicine can be implemented topical anesthesia to mucous membrane of urethra and mucous membrane of urinary bladder uniformly, and patient just can not feel partial uncomfortable, tolerance catheter that just can be pleasant.
This utility model can also be told another local anaesthetics isocon that is symmetrically distributed with the water pocket flow in pipes on circumference on the anaesthetic flow in pipes, establish several local anesthetic ejection holes in the length range of this pipe insertion human body urethra, this segment length can be according to adult, child, man, woman's different designs.
Present widely used catheter scarcely is with the anaesthetic flow in pipes, and pre-notes pipe of the present utility model also can be directly and the supporting use of using at present of ordinary urethral catheter, to alleviate the misery of patient when the intubate.
Because the mode that this utility model adopts pre-notes pipe and catheter to be used in combination, alleviated the discomfort of patient when plugging in catheter greatly, and can after inserting good catheter, individual variation and the requirement according to patient in the anaesthetic flow in pipes, be interrupted the injection anaesthetic, alleviate the misery of patient after catheter inserts, very favourable to patient's treatment and physical and mental health.
