Abstract
A disposable ureter guide pipe belongs to a medical device and comprises a head part sealed cone-shaped guide pipe body with length marks curved on the surface of the circumference, and a guide steel wire matched with the inner chamber of the guide pipe body and provided with a ring-shaped handle at the tail part. The disposable ureter guide pipe is characterized in that at least one elliptical and spherical expansion ball is designed at the circumference of the neck part of the guide pipe body, and at least one drainage hole communicated with the inner chamber of the guide pipe is designed at the maximal diameter part of each expansion ball; a clamping ring is designed at the periphery of the tail part of the guide pipe body; and the tail part of the guide pipe body, below the clamping ring, is clamped with a movable joint for injection. At least one elliptical and spherical expansion ball is designed at the circumference of the neck part of the guide pipe body, and the diameter of the expansion ball is designed in the way that the larger the distance to the head part of the guide pipe body, the larger the diameter is. Trying out shows that the head part not only can play the effect of repeatedly and progressively expanding a blocked ureter, but also can remove deposits in the blocked ureter in one step; and the tail part can be exactly matched with a medicine injector for injecting liquid medicine without leakage.
Description
Technical field
The invention belongs to disposable medical article, dredge the disposable use ureteral catheter that ureter is used especially for expansion.
Background technology
Ureteral catheter is a kind of expansion mediation ureter that is used for, and cooperates Ureteroscopy, with the disposable medical article of symptomatic treatment.Existing disposable use ureteral catheter; As shown in Figure 4; Comprise that head seals into the catheter body 01 that cone shape, outer surface are carved with length mark, be matched with the guide wire 02 that catheter body inner chamber, afterbody have the annular handle, be designed with conduction hole 04 in the catheter body incidence.There is following deficiency in actual use in the disposable use ureteral catheter of prior art:
1, stops up serious patient for ureter; In order progressively to expand the mediation ureter; Must repeatedly change the disposable use ureteral catheter that catheter body 01 external diameter increases gradually,, remove the deposit in the ureter that stops up gradually progressively to expand the ureter that stops up.Disposable use ureteral catheter is repeatedly changed in having in the wound inspection like this, has caused great misery to the patient, the risk of the patient's urinary tract infection that also has been multiplied on the one hand; On the other hand, meaning repeatedly increases medical treatment cost, has not only increased patient's financial burden, and causes the wasting of resources, disagrees with the low-carbon (LC) theory.
2, when needing liquid medicine injection in the mediation ureter process or after finishing; Can only stretch into catheter body 01 afterbody inner chamber with the syringe needle of syringe; Since the syringe needle of syringe with do not have tight cooperating during catheter body 01 afterbody inner chamber designs, must cause the leakage of medicinal liquid, had a strong impact on therapeutic effect.
This shows; Research also designs a kind of head and can play repeatedly the ureter that progressively expansion is stopped up; Can once remove the deposit in the ureter of obstruction again, and afterbody can also not have the disposable use ureteral catheter that leaks the tight cooperation cartridge syringe liquid medicine injection in ground be necessary.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; Design a kind of head and can play repeatedly the ureter that progressively expansion is stopped up; Can once remove the deposit in the ureter of obstruction again, and afterbody can also there be the disposable use ureteral catheter that leaks the tight cooperation cartridge syringe liquid medicine injection in ground.
The objective of the invention is to realize like this: a kind of disposable use ureteral catheter; Comprise that head seals into the catheter body that cone shape, outer surface are carved with length mark; Be matched with catheter body inner chamber, afterbody and have the guide wire of annular handle; It is characterized in that catheter body incidence periphery is designed with at least 1 spherical expansion ball of ellipse, the diameter maximum of each expansion ball is designed with at least 1 conduction hole that is communicated in the catheter body inner chamber; Catheter body afterbody periphery is designed with the clamping ring; Catheter body tail end below the clamping ring is connected with the injection active joint.
The object of the invention can also adopt following further technical measures to realize:
The diameter that described catheter body incidence periphery is designed with at least 1 spherical expansion ball of ellipse is designed to: the position is big more apart from the catheter body head, and its diameter is big more.The technique effect of this design is in use patient's ureter progressively to be expanded, and removes the deposit in the ureter that stops up gradually.
Be interference fit between the anterior tubular intracavity of catheter body tail end external diameter below the described clamping ring and injection active joint.The technique effect of this design is to make tight cooperation the between the anterior tubular intracavity of catheter body tail end and injection active joint, can not let liquid leakage.
Be interference fit between the front end periphery of described injection active joint rear portion Taper Pipe shape inner chamber and common drug syringe.The technique effect of this design is to make tight cooperation the between the front end periphery of injection active joint rear portion Taper Pipe shape inner chamber and common drug syringe, can not let liquid leakage.
The disposable use ureteral catheter that the present invention's enforcement obtains through on probation, has compared with prior art shown following beneficial effect:
1, the ureteral catheter head can play repeatedly the ureter that progressively expansion is stopped up, and can once remove the deposit in the ureter of obstruction again.The disposable use ureteral catheter of prior art is in order progressively to expand the mediation ureter; Must be repeatedly; Change the disposable use ureteral catheter that the catheter body external diameter increases gradually as 3 times, 5 times; In contrast to this, catheter body incidence periphery is designed with at least 1 diameter to be designed to the position big more apart from the catheter body head among the present invention, the oval spherical expansion ball that its diameter is big more; Employing has the disposable use ureteral catheter expansion ball, that the present invention's enforcement obtains that 3,5 diameters increase successively; Only need to use once, just play prior art and change for 3 times, 5 times the effect of the disposable use ureteral catheter that the catheter body external diameter increases gradually, with repeatedly progressively the ureter that stops up of expansion be simplified to and once accomplish the deposit of removing in the ureter that stops up.
2, the ureteral catheter afterbody can not have the tight cooperation cartridge syringe liquid medicine injection in the ground of leakage.Cause the leakage of medicinal liquid to compare in actual use with the disposable use ureteral catheter of prior art, the present invention implements the disposable use ureteral catheter that obtains because the catheter body tail end below the trailer card T-Ring is connected with the injection active joint.And be interference fit between catheter body tail end external diameter below the clamping ring and the anterior tubular intracavity of injection active joint, be interference fit between the front end periphery of injection active joint rear portion Taper Pipe shape inner chamber and common drug syringe.Guaranteed that the front end periphery of clamping and common drug syringe is the injection active joint of interference fit easily when needing liquid medicine injection in the mediation ureter process or after finishing; Guaranteed that the injecting liquid drug process do not have leakage.
