Abstract

The utility model belongs to the field of medical appliances, particularly a drainage tube for urethral catheterization. A tube body of the drainage tube forms a cone shape, a liquid inlet hole is arranged at the top end part of the cone and a tube wall gradually becomes thinner along the direction of the liquid inlet hole. The utility model made from flexible materials is designed according to the characteristics of the urethra of the human body, and the utility model can be conveniently inserted into the urethra for use. The phenomena, such as pain caused by the insertion, etc., can not be generated, the utility model curves in company with the curve of the urethra, the external surface of the tube wall is smooth, and the wall of the urethra and the internal theca can not be damaged, so a patient can not feel painful or discomfortable. The liquid inlet hole of the drainage tube is arranged on the top end of the tube body to ensure that urine liquid can be smoothly guided out. Adverse reactions, such as odynuria, fear of urination, inflammation, infection, etc., can not happen after the utility model is used.

Description

Urinary catheter

This utility model belongs to medical instruments field, specifically a kind of Urinary catheter.

Anyone is subjected to the threat of various disease in life unavoidably at it, and some diseases causes the patient and situations such as urination inconvenience or dysuria occur when serious.Under these circumstances, just must solve the problem of urinating, to reach the auxiliary treatment purpose by the external force apparatus.At present, medical system all adopts drainage device to finish this process, and several sections such as the basic structure drainage tube of used drainage device, liquid storing bag, discharging tube are formed.Drainage tube body wherein is cylindric, and the position, top is the cross section body, and the crooked characteristics of human body urinary tract itself are not catered in this design, in use, phenomenons such as pain can occur inserting, and the patient is agonized.And liquid-entering hole is opened in tube wall, is unfavorable for the inflow of urine, makes the urethral catheterization effect bad.Because the construction features of drainage tube makes it can leave corner angle or burr on body in processing technology, can cause damage to urethral wall and inner membrance like this, very easily allows the patient ill symptomses such as dysurea, timid urine, inflammation, infection occur after usefulness.

The purpose of this utility model be to provide a kind of rational in infrastructure, urethral catheterization is respond well and use the Urinary catheter that has no adverse reaction.

The purpose of this utility model can realize by following measure:

A kind of Urinary catheter, its body is coniform, and vertex of a cone position has liquid-entering hole, and tube wall is along to vertex of a cone liquid-entering hole direction attenuate gradually.

This utility model has following advantage compared to existing technology:

This utility model is made up of soft material, features simple structure, and the drainage tube front end is coniform, is convenient to insert and does not have pain, and liquid-entering hole is located at the position, top, is convenient to urine and flows into drainage tube.And body itself is coniform, and tube wall is along to liquid-entering hole direction attenuate gradually, thus body deliquescing gradually.Like this, in use, can cater to the crooked characteristics of urinary tract itself,, be difficult for the pain phenomenon is inserted in its generation along with urinary tract is crooked and crooked.And therefore top and body slyness can not produce a bit damage to urethral wall and inner membrance, can not bring to user not accommodate misery, have avoided untoward reaction such as the dysurea of using the back to occur, timid urine, inflammation, infection.And urethral catheterization is smooth and easy, works very well.

Accompanying drawing is a structure cutaway view of the present utility model:

1-body 2-liquid-entering hole

This utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:

A kind of Urinary catheter, body 1 is coniform, and position, vertex of a cone end has liquid-entering hole 2, and tube wall is along to pyramid tip liquid-entering hole 2 directions attenuate gradually.Drainage tube internal diameter 2.8mm wherein, tube wall thicker part 0.5mm, attenuate gradually, to top liquid-entering hole 2 places, liquid-entering hole 2 diameters are 1.2mm.It is primary raw material that this utility model material adopts nontoxic, aseptic, apyrogenic high-quality polrvinyl chloride, during use through cobalt-60 radiation sterilization, so use this utility model safety, reliably.

Claims

1. a Urinary catheter is characterized in that body (1) is coniform, and vertex of a cone position has liquid-entering hole (2), and tube wall is along to vertex of a cone liquid-entering hole (2) direction attenuate gradually.
