Abstract
The utility model discloses a novel indwelling catheter drainage expander, and relates to the technical field of medical instruments. The novel indwelling catheter drainage expander comprises a pipe body. The pipe body is cylindrical, a main hole is arranged inside the pipe body, a side hole is arranged at the tail end of the pipe body, a pointed end is arranged at the front end of the pipe body and is conical, and scale marks are arranged on the pipe body. The novel indwelling catheter drainage expander has the advantages of being simple in structure, convenient to use, low in manufacture cost and convenient to popularize and use, the depth of the expander to enter a human body can be controlled easily, whether the expander enters the renal pelvis after entering the human body can be judged conveniently, and work burden of medical workers is lightened.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of novel catheter drainage dilator.
Background technology
In PTBD, such as the capable pyelostomy of hydronephrosis under the ultrasonic guidance, after entering renal pelvis, success guiding puncture silk to use dilator, then just can put pipe, this step is very crucial, the dilator that uses does not at present have the graduation mark of metering depth, normally determine paracentesis depth by operator's feel or with the ruler measurement in the operation, dilator enters the bad grasp of the degree of depth of human body, the shallow nephrorrhagia that easily causes punctured, cross the damage that deeply then easily causes kidney base of a fruit trunk, increased operation risk, whether dilator enters sometimes bad judgement of renal pelvis after entering human body in addition.
The utility model content
This utility model is for the prior art above shortcomings, a kind of novel catheter drainage dilator is provided, the design of this novel catheter drainage dilator by graduation mark is so that dilator enters the degree of depth of human body can well be grasped, novel expanded device has increased a side mouth, can connect syringe, whether have liquid flow out or filling liquid, whether ultrasonic can the observation has liquid to enter renal pelvis, pyelostomy is successfully completed be very helpful if aspirating.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of novel catheter drainage dilator comprises body, and described body is cylindrical, is provided with main aperture in the described body, and described body end is provided with side opening, and described body front end is provided with tip, and it is conical that described tip is, and described body is provided with graduation mark.
Described body is made of plastics.
This utility model beneficial effect: simple in structure, easy to use, dilator enters the degree of depth of human body and easily grasps, and conveniently judges after dilator enters human body whether enter renal pelvis, has alleviated medical worker's work load, and cost of manufacture is low, is convenient to promote and use.
Description of drawings
Fig. 1 is novel catheter drainage dilator structural representation described in the utility model.
Among the figure:
The 1-body; The 2-main aperture; The 3-side opening; The 4-tip; The 5-graduation mark.
The specific embodiment
The below is described in further detail this utility model with embodiment with reference to the accompanying drawings:
As shown in Figure 1, a kind of novel catheter drainage dilator, comprise body 1, described body 1 is made of plastics, body the 1 transparent medical worker of being convenient to observe, described body 1 is cylindrical, be provided with main aperture 2 in the described body 1, described body 1 end is provided with side opening 3, and novel expanded device has increased a side mouth, can connect syringe, whether have liquid flow out or filling liquid, whether ultrasonic can the observation has liquid to enter renal pelvis, pyelostomy is successfully completed be very helpful if aspirating, alleviated medical worker's work load, described body 1 front end is provided with tip 4, and it is conical that described tip 4 is, and described body 1 is provided with graduation mark 5, avoided determining paracentesis depth by operator's feel or with the ruler measurement in the operation in the past, dilator enters the bad grasp of the degree of depth of human body, and the shallow nephrorrhagia that easily causes that punctured is crossed the drawback that deeply then easily causes the damage of kidney base of a fruit trunk, not only alleviate patient's misery, and reduced medical worker's work load and pressure.
During use, dilator thrusts human body, and whether suitable by graduation mark 5 observation places, the side mouth can connect syringe, and whether aspirate has liquid to flow out, or filling liquid, and whether ultrasonic can the observation has liquid to enter renal pelvis.
Claims (2)
