Description

Automatic catheter clip

Technical Field

The utility model relates to a soft catheter switch, in particular to an automatic fixed opening or blocking device arranged outside a catheter.

Background

The existing catheter clip is a common plastic clip or a Robert cutoff clip which is manually operated, the existing catheter clip is opened or closed at regular time according to the instruction of a doctor, a patient or an attendant needs to operate a switch of the catheter clip at regular time, and the patient or the attendant is hard to attend in 24 hours.

The publications such as CN204092659U and CN209984217U relate to a controllable valve, a valve body can be contacted with the liquid in the environment of a human body, the requirement on the sanitation grade of the valve body is high, and the controllable valve is not easy to popularize. The pressure sensors of the patent publications CN207101553U and CN2055054980U are also placed inside the catheter, and have the same problems of high hygiene requirements and high cost.

The authorized bulletin number CN 208660098U announces a timed urination device for an indwelling catheter, the blocking structure adopts a screw rod slider mechanism to block the catheter, the structure is complex, the timing is controlled by a remote controller, the integration degree of the device is low, the structural parts are dispersed, the cost is high, the blocking execution structure is formed by compressing the slider to the wall of the catheter in an extruding mode, and the uncertainty exists in how to accurately control the stroke due to the manufacturing tolerance and the difference of hardness and softness of the catheter.

SUMMERY OF THE UTILITY MODEL

In order to reduce the nursing requirements, the device controls the opening and closing of the catheter by an electric control timing mechanism. And the control mechanism is external, and the structure of the existing catheter and urine bag is not changed.

The utility model provides a structure for blocking and opening a catheter, which can enable the catheter to generate an acute angle to be folded in half to block flow when the catheter needs to be blocked and closed. When the opening is performed, the mechanism drives the guide pipe to be flattened, and reliable opening is realized.

Technical scheme

The utility model uses a singlechip to set time and control a worm gear and worm brush speed reducing motor to rotate, a catheter shifting sheet is fixed on an output shaft of the speed reducing motor, and when the speed reducing motor rotates, the catheter shifting sheet on the output shaft of the motor is driven to fold the ureter twice at an acute angle so as to cut off liquid in the catheter.

When the speed reducing motor rotates reversely, the guide pipe is driven to be flattened. The catheter is placed in a conducting state. The time length of opening and closing is set through the keys and the display interface, so that the catheter is in an opening or closing state according to the time length set by people.

Advantageous effects

The catheter has the advantages that the catheter can absorb the manufacturing tolerance of different thicknesses or hardness of the catheter, and is more reliable compared with a structure for locking the catheter by using a fixed gap. The principle that the flow can be cut off can be realized by utilizing the doubling up of the catheter, the specific catheter shifting piece is fixed by the output end of the motor and is matched with the raised shape of the shell, and the motor drives the ureter to be doubled up or unfolded at an acute angle when rotating, so that the effect of choked flow or opening is achieved.

The names of the components are as follows:

in the figure, 1, a protective cover, 2, a main shell, 3, a rear cover, 4, a guide pipe, 5, a keyboard interface, 6, a nixie tube, 7, a guide pipe shifting piece, 8, a main shell bulge, 9, an output shaft, 10, a photoelectric switch blocking piece, 11, a circuit board, 12, a photoelectric switch, 13, a direct-current power socket, 14, a worm gear speed reducing motor and 15, and a key is immediately turned on.

The specific implementation mode is as follows:

the shell is composed of three parts: a protective cover (1), a main shell (2) and a rear cover (3).

The execution units are a motor (14) and a conduit shifting piece (7), wherein the photoelectric switch blocking piece (10) and the conduit shifting piece (7) are both fixed on an output shaft (9) of the motor and synchronously rotate with the output shaft (9) of the motor.

The control unit is a circuit board (11).

The human-computer interaction setting unit comprises a keyboard interface (5) and a digital tube (6).

The photoelectric switches (12) are all welded on the circuit board (11). Except for the protective cover (1), other components are fixed to the main casing (2). The protective cover (1) plays a role in protection and prevents the moving part from contacting with a human body and preventing the key from being triggered by mistake.

The external power supply can adopt a battery or a power adapter, and 9V direct current power supply is provided for the system through a power socket (13).

The circuit board (11) is provided with a clock chip and a singlechip, and the blocking of the conduit (4) and the setting of the opening time length are completed through the keyboard (5) and the nixie tube (6). The circuit board (11) drives the motor (15) to automatically run according to the setting.

When the catheter is in the opening state, the catheter shifting sheet (7) is far away from the catheter, and in the opening process, friction exists between the catheter shifting sheet (7) and the catheter (4) and can drive the catheter to be flattened.

When the catheter is blocked and opened, the limit position of the stopping of the catheter shifting piece (7) is determined by a signal detected by the photoelectric switch blocking piece (10).

The extreme positions of the opening or blocking of the catheter paddle 7 use the configuration of the opto-electronic switch 12 and the opto-electronic switch barrier 10.

The keyboard interface is provided with a key (15) which is opened immediately to deal with the situation that the catheter needs to be opened immediately. The protective cover can be opened under the condition of power failure, and the catheter can be directly pulled out to deal with extreme conditions.
