Abstract
The utility model relates to the field of medical equipment, concretely relates to catheter with anesthesia function for reaching above purpose, provides a catheter with anesthesia function, including sacculus and flow in pipes, flow in pipes and sacculus intercommunication, the extexine of flow in pipes has the through -hole, has predetermine the seal wire in the flow in pipes, and it can the joint to have on the seal wire the arch of through -hole, there is the inclined plane towards the catheter afterbody in the arch. The beneficial effects of the utility model are that, alleviate the discomfort that patient pulled out the catheter, be fit for the postoperative and use, made patient can endure the catheter pleasurably, can not produce the problem of urine from other pipelines refluences simultaneously.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of catheter with anesthesia function.
Background technology
To the patient needing the long period to perform the operation in clinical, coma patient and other need the patient of urethral catheterization or indwelling catheter, often because catheter is to the stimulation of mucous membrane of urethra and mucous membrane of urinary bladder, especially patient is made to be difficult to stand to the stimulation of Posterior urethral and trigone of urinary bladder, show as agitation, frequent micturition desire, very painful, thus bring out increased heart rate, blood pressure rising etc., to the physical and mental health of patient and the recovery of disease totally unfavorable.
For addressing this problem, medical circle has made a large amount of research work, if publication number is " CN101108147A ", application number is " 200710066141.3 ", name is called that " disposal indolence catheter external member for medical purpose " discloses a kind of catheter, the disposal indolence catheter external member for medical purpose be made up of pre-note pipe and catheter, pre-note pipe notes local anaesthetics in advance to mucous membrane of urethra and mucous membrane of urinary bladder before plug in catheter, alleviate and comment the sense of discomfort of people when inserting conduit, catheter after intubate to mucous membrane of urethra and mucous membrane of urinary bladder surface anesthesia, enable the tolerance that patient is pleasant, and according to the individual variation of patient and can require to intermittent infusion anaesthetic in anaesthetic flow in pipes, alleviate the misery that patient inserts at catheter.By setting up the passage that is injected anesthesia in catheter, and with note in advance pipe and coordinate and inject anaesthetic, but the design of this catheter can cause catheter diameter to increase, as catheter in art with there being certain use value, but use as post-treatment catheters and be then not suitable for, because general postoperative catheter does not have too much sense of discomfort for making patient, generally select the catheter that diameter is less, and the less catheter of diameter cannot carry out injection anaesthetic in this way; Another shortcoming of this catheter is, the access opening of injection anaesthetic is in long-term connected state, easily makes urine be flowed out by the pipeline injecting anaesthetic by through hole, is unfavorable for the operation of medical personnel.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can adapt to the catheter that postoperative urethral catheterization, sealing effect alleviate patient suffering better simultaneously.
For reaching above object, a kind of catheter with anesthesia function is provided, namely there is the catheter of anesthesia flow in pipes, comprise sacculus and flow in pipes, flow in pipes is communicated with sacculus, the extexine of described flow in pipes has through hole, is preset with seal wire in flow in pipes, seal wire has the projection of through hole described in energy shutoff.Described flow in pipes is anesthetis flow in pipes, can built-in anesthetis.
Preferably, described projection there is inclined-plane.Bevelled projection is easily extracted.
Preferably, described projection is taper.
Preferably, described flow in pipes outer surface there is through hole to form a line, described seal wire has the protruding shutoff through hole of string.
Preferably, the cross section of described seal wire is oblate.
Preferably, described through-hole diameter is 2mm to 3mm.
The catheter with anesthesia function of the present utility model, flow in pipes is utilized to hold passage as anesthetis, in injection channel, upper surface is provided with through hole, make can to control in catheter withdrawal process anesthetis to go deep into skin surface by through hole and reach anaesthetic effect, its control method is by presetting seal wire in injection channel, seal wire being provided with projection, in catheter use procedure, seal wire projection can clogging through hole, prevents anesthetis from overflowing or urine is infiltrated; When catheter needs to pull out, can be extracted by seal wire along flow in pipes, owing to seal wire having towards the inclined-plane of catheter afterbody, therefore seal wire is easy to mobile when caudad direction pulls out.
The beneficial effects of the utility model are, alleviate the discomfort that patient pulls out catheter, are applicable to postoperative use, make patient cosily can tolerate catheter, can not produce the problem that urine flows backwards from other pipelines simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1:
A kind of catheter with anesthesia function according to Fig. 1,2,3, comprises urethral catheterization pipeline 1 and flow in pipes 3, the head end of urethral catheterization pipeline 1 has urethral catheterization hole 2, catheter has sacculus 4, flow in pipes 3 has the hole be connected with sacculus 4.The side at sacculus 4 place is the head end direction of catheter, and the other end is tail end, tail end has the urethral catheterization Petrochemical Pipe Joints 5 be connected with urethral catheterization pipeline 1 and the flow in pipes union joint 6 be connected with flow in pipes 3.The outer surface of flow in pipes 3 has string through hole 9, the diameter of through hole 9 is 2mm.Flow in pipes 3 internal preset has seal wire 7, and seal wire 7 cross section is oblate, oblateness has the projection 8 of taper, is connected in through hole 9, and the inclined-plane of protruding 8 is the conical surface.
Embodiment 2:
There is a catheter for anesthesia function, during use, urethral catheterization Petrochemical Pipe Joints 5 is connected urinary bag, anesthetis is injected in flow in pipes joint 6, fill sacculus 4, because the projection of preset seal wire 7 can block through hole 9, therefore anesthetis can not overflow along through hole 9.When pulling out catheter, extracted out by seal wire 7 along flow in pipes 3 from flow in pipes joint 6, because the projection 8 on seal wire 7 has inclined-plane, and inclined-plane is towards catheter tail end, therefore meets obstructions in extraction little, and seal wire 7 is bending easily, extracts out smoothly.After extraction, pre-filled anesthetis overflows along through hole 9, and anaesthetic skin surface, makes Removal of uriethral catheter can not bring too much sense of discomfort to patient.
Below the preferred embodiment that this utility model is created is illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the prerequisite without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all included in the application's claim limited range.
