Abstract

The utility model provides a disposable using aseptic catheter, which relates to the field of medical machineries. The structure has the characteristics that a controller (2) is arranged on one end which is close to a conical interface of an excretory canal (1), and a pulley (3) which is capable of reciprocally rolling is arranged in the controller (2). The utility model has the advantages of reasonable design, simple structure, simple operation, safety and reliability, and is suitable to be popularized.

Description

The aseptic catheter of disposable use

Affiliated technical field

This utility model relates to medical instruments field, relates to the aseptic catheter of disposable use particularly.

Background technology

In the prior art, give patient's urethral catheterization clinically, generally all be to use two-chamber sacculus formula catheter, though convenient feasible advantage is arranged, but there is following shortcoming simultaneously: the one, in the process of intubate, have urine and continuously outflow, the operation of water filling in sacculus and connection urinal is made troubles; The 2nd, urine retention patient, full as bladder excessive, and patient's extremely feeble, it is slowly suitable to urinate, and put the urine amount first and should not surpass 1000ml, in order to avoid the bladder sudden pressure reduction is hemorrhage or faint, need control flow velocity and interruption to put urine, the patient of especially long-term indwelling catheter, bladder is because of the full contracture of no urine, answer intermittent drain clamp before tube drawing, its troublesome poeration is wasted time and energy.

Along with the development of society, progress of science and technology, numerous medical personnel thirst for an a kind of property time and use appearing on the market of aseptic catheter, with the demand of the medical and nursing work of satisfying people.

Summary of the invention

This utility model provides a kind of new disposable and uses aseptic catheter, and it was both reasonable in design, and was simple in structure, and is easy to operate again, high efficiency.

Task of the present utility model realizes that by following proposal the main feature of its structure is to be provided with controller 2 at the end near excretory duct 1 cone-shaped interface place, is provided with the pulley 3 that can back and forth roll in it.

The characteristics of its structure are the pulleys 3 in the controller 2, can up and down reciprocatingly roll along the inner edge at the edge of controller 2, when it was in the upper position of controller 2, excretory duct 1 began to drain, when it was in the lower position of controller 2, excretory duct 1 was in closed condition.

Good effect of the present utility model is that it is reasonable in design, and is simple in structure, easy to operate, with low cost.Owing in controller 2, be provided with the pulley 3 that can back and forth roll, can control the flow velocity of catheter so it not only can control the catheter switch.

The specific embodiment

Following accompanying

drawing

1,2,3 describes the details and the work process of the aseptic catheter of disposable use that the utility model proposes in detail.

In Fig. 1, Fig. 2, Fig. 3, at a end controller 2 is housed near excretory duct 1 cone-shaped interface place, be provided with the pulley 3 that can back and forth roll in it, pulley 3 can up and down reciprocatingly roll along the inner edge at the edge of controller 2, when it is in controller 2 upper positions (shown in Figure 1), excretory duct 1 begins to drain, and when it was in controller 2 lower positions, excretory duct 1 was in closed condition.Its work process is as follows, when giving aeg's urethral catheterization, catheter eye with holes 5-end is inserted the about 3-4cm of urethra, and seeing has urine via eyelet 5, flow out from excretory duct 1 cone-shaped interface, and the switch of closing controller 2, as shown in Figure 3.After continuation is inserted 2-3cm with catheter, inject the 5-10ml sterilized water from the cone-shaped interface that fills up pipe 4, the cone-shaped interface with excretory duct 1 is connected with the urinal interface then, opens the pulley 3 of controller 2 again, as shown in Figure 1, and promptly sustainable urethral catheterization.As need control flow velocity, as long as the pulley 3 of controller 2 is rolled into required flow rate (not drawing among the figure) gently downwards.

The aseptic catheter of this disposable use may command, the patient of applicable any age and sex.It is reasonable in design, and is simple in structure, easy to operate, time saving and energy saving, can alleviate medical personnel's labor intensity, safe and reliable.Can make patient satisfaction, satisfy nursing staff's job demand, be suitable for popularizing.

Claims

One kind contain excretory duct, fill up pipe, the aseptic catheter of the disposable use of double-lumen air sac formula of sacculus, eyelet, it is characterized in that being provided with controller (2) at a end near excretory duct (1) cone-shaped interface place, be provided with the pulley (3) that can back and forth roll in it.
2. according to the aseptic catheter of right 1 described disposable use, it is characterized in that set pulley (3) in the controller (2), it can up and down reciprocatingly roll along the inner edge at the edge of controller (2), and when it was in the upper position of controller (2), excretory duct (1) began to drain; When it was in the lower position of controller (2), excretory duct (1) was in closed condition.
