Description

Catheter

Technical Field

The utility model relates to the technical field of medical equipment, especially a catheter.

Background

In the traditional field, the catheterization is the common operation in the patient that can not urinate by oneself carries out the auxiliary catheterization, and the purpose helps the patient that can not urinate by oneself to derive the urine in the bladder, and nurse help patient inserts the catheter and carries out the catheterization usually clinically, and some patients can oneself intubate and carry out the catheterization. When a doctor conducts catheterization operation on a patient clinically, the patient is painful in the intubation process due to the fact that the surface of the catheter is too rough; when in catheterization, the urethra of a patient with large prostate gland is very narrow, the common straight-head catheter is very difficult to intubate, the patient is very painful, and the intubating success rate is very low.

In order to better solve the above problems, various new catheters have been produced and developed, but these catheters always have the problems, and the use history of the catheters has low intubation success rate, risks of skin allergy, coating falling off in the body, urethral calculus, poor lubricating performance and the like. The existence of the danger causes hidden troubles to patients, and the condition can cause serious consequences, even threatens the lives of the patients, delays the treatment time of the patients and brings great pain to the patients and family members of the patients.

Disclosure of Invention

The to-be-solved technical problem of the utility model is to the not enough of prior art, provide a catheter of simple structure, safe in utilization.

The utility model aims to solve the technical problem that the catheter is realized by the following technical scheme that the catheter comprises a columnar pipe body with one open end, wherein the open end of the columnar pipe body is connected with a urine outlet joint, and the other end of the columnar pipe body is provided with a pipe body insertion head with an ellipsoidal end part; the columnar pipe body between the open end and the pipe body insertion head is further provided with a plurality of urine inlets, and the columnar pipe body is further provided with a UV curing coating layer for facilitating installation of the catheter.

The to-be-solved technical problem of the utility model can also be realized through following technical scheme, above a catheter, the body insert the head through circular arc transitional coupling on the column body.

The to-be-solved technical problem of the utility model can also be realized through following technical scheme, above a catheter, the urine import be equipped with 2 at least.

The to-be-solved technical problem of the utility model can also be realized through following technical scheme, above a catheter, the crisscross setting of urine import on the column body.

The to-be-solved technical problem of the utility model can also be realized through following technical scheme, above a catheter, the urine import set up on the column body with the central line symmetry of column body.

The to-be-solved technical problem of the utility model can also be realized through following technical scheme, above a catheter, adjacent urine import interval is 2cm setting.

The to-be-solved technical problem of the utility model can also be realized through following technical scheme, above a catheter, insert the nearer urine import of head and insert first 2cm settings apart from the body.

Compared with the prior art, the utility model has the advantages as follows:

(1) the catheter can be conveniently inserted into the urethra through the catheter body insertion head, the UV curing coating arranged on the catheter can avoid the irritation of the catheter to urethral mucosa and the pain of patients in the process of intubation, and the UV curing coating has safe components and can effectively prevent the urethral mucosa from being damaged;

(2) this body male head sets up to the ellipsoid form, and body male head passes through circular arc transitional coupling on the column body, and this design can be through constrictive urethra, and body male head surface is burr-free, no matter intubate and tube drawing all are not fragile and injure the urethra mucosa, its reasonable in design, simple structure, and the intubate is easy, convenient to use.

Drawings

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is another schematic structural diagram of the present invention;

fig. 3 is another schematic structural diagram of the present invention.

Detailed Description

The embodiments of the present invention will be further described with reference to the accompanying drawings so as to facilitate the further understanding of the present invention by those skilled in the art, and do not constitute a limitation to the right thereof.

Embodiment 1, referring to fig. 1, a urinary catheter includes a cylindrical tube body 1 having an open end, the open end of the cylindrical tube body 1 is connected to a urine outlet connector 2, and the other end of the cylindrical tube body 1 is provided with a tube body insertion head 3 having an ellipsoidal end; a plurality of urine inlets 4 are further arranged on the columnar pipe body 1 between the open end and the pipe body insertion head 3, and a UV curing coating 5 for conveniently installing the catheter is further arranged on the columnar pipe body 1. UV curing generally refers to the curing conditions or requirements of coatings, inks, adhesives or other potting sealants that require curing with ultraviolet light, which is different from thermal curing, curing agent curing, natural curing, and the like; the UV curing coating 5 is arranged on the catheter, so that the stimulation of the catheter to urethral mucosa can be reduced when a patient uses the catheter, the urethral mucosa is not easily damaged no matter the catheter is inserted or pulled out, the UV curing coating 5 cannot fall off in the validity period of the product, and the use is convenient; the UV coating can be formed by coating through methods such as dip coating, curtain coating, paint coating, spin coating, even vacuum coating and the like, and then curing and film forming through ultraviolet photon irradiation, and has moderate hardness, good flexibility and aging resistance;

wherein, the body that the ellipsoid set up inserts head 3 can pass through constrictive urethra, and whole use user can not feel any discomfort, and the catheterization is effectual.
