Description

Medical catheter fixing device with alarm function

technical field

The invention relates to a medical catheter fixing device, in particular to a catheter fixing device with an alarm function.

Background technique

Clinically, some patients, especially severe patients, often need to indwell multiple catheters in the body due to disease or surgery, such as nasogastric tubes, postoperative drainage tubes, urinary catheters, etc., to ensure the needs of treatment. During catheter indwelling, accidental slippage of the catheter has become a common problem in clinical departments, especially in the ICU. Patients who require recannulation after accidental catheter slippage have a 25% fatality rate. Therefore, it is particularly important to effectively prevent accidental slippage of the catheter.

At present, there are various techniques for catheter fixation, such as inflating a balloon inside the catheter or fixing it with adhesive tape outside the catheter. However, once the fixation device is obstructed, such as air bag leaks or the adhesive tape becomes poor, and the catheter slips, the catheter itself does not have the slipping alarm function, so that the medical staff cannot detect and deal with it in time under normal circumstances, resulting in partial or partial failure of the catheter. All slip off, requiring medical staff to re-intubate, and may even cause serious consequences.

Contents of the invention

In order to overcome the deficiency that there is no obvious warning at the initial stage of catheter slippage, the present invention provides a medical catheter fixing device with an alarm function. The device not only has the function of fixing the catheter, but also emits a buzzing sound when the catheter is out of the original fixed position, attracting the attention of the medical staff and taking measures in time. The operation is simple, and it can prevent the catheter from slipping while fixing the catheter.

The present invention is realized through the following technical solutions: a butterfly-shaped film, the film is sticky, one side can be adhered to the patient's skin, and a catheter clamping device is adhered to the other side. The catheter clamping device is divided into two parts: elastic movable device and buzzer alarm device. The elastic movable device and the buzzer alarm device respectively have a clamping surface directly contacting the catheter.

The elastic movable device is provided with a spring, and the spring is connected with the towing bar and the clamping surface.

The buzzer alarm device consists of an indicator light, a buzzer, a switch, a shunt resistor and a clamping surface. There are two metal contacts on the clamping surface. The power supply, switch, indicator light and buzzer are connected in series. Two wires lead out from both sides to connect the metal contacts.

When in use, the expansion and contraction of the spring is adjusted by sliding the drag bar on the track, and the conduit glued with the conductive metal tape is placed between the two clamping surfaces of the conduit clamping device. Turn on the switch, the indicator light is on, the conductive metal tape on the catheter contacts the metal contact on the catheter clamping device to form a path, which acts as a shunt resistor to short-circuit the buzzer, and the circuit is normal. When the catheter slips, the conductive metal tape is not connected to the metal contact, the function of the shunt resistance is lost, and the buzzer emits a buzzing sound.

The beneficial effect of the present invention is that one side of the catheter fixing device is fixed on the patient's skin, and the other side can clamp and fix catheters of different calibers. When the part of the catheter with metal conductive glue leaves the clamping surface, a buzzer can be heard to achieve the purpose of warning.

Detailed ways

In Fig. 1, the catheter clamping device (12) is arranged on the butterfly film (8), and consists of two parts, an elastic movable device (14) and a buzzer alarm device (15). The distance between the two parts can be adjusted by pulling the drag bar (5) to realize the central holding of catheters with different calibers. The surface of the two clamping surfaces (13) has a rough surface effect to strengthen the fixing between the metal conductive adhesive tape (6) with the toothed surface. The buzzer alarm device (15) is provided with a circuit as shown in Figure 2 inside.

In Fig. 2, the indicator light (1), switch (2), buzzer (9) and the power supply form a path in series, a shunt resistor (10) is connected in parallel at the buzzer (9), and the buzzer ( 9) Short circuit.

In Fig. 3, pull the drag bar (5) to slide on the track (11), and adjust the distance between the two clamping surfaces (13) after compressing the spring (4). The conduit (7) is in contact with the metal contact (3) to form a path to play the role of a shunt resistor. After the switch (2) is turned on, the indicator light (1) is on, and the circuit is normal. If the part of the conduit (7) pasted with the metal conductive tape (6) slips out of the clamping surface (13), the path formed by the connection with the metal contact (3) is disconnected, the shunt effect disappears, and the buzzer (9) sounds , play an alarm role.

In the embodiment shown in Fig. 4, the metal conductive tape (6) is pasted on the medical catheter, and the safe length of the catheter sliding can be controlled by adjusting the width of the metal conductive tape (6).

In Fig. 5, the contact surface (16) of the butterfly-shaped film sticks to the device, and the skin contact surface (17) of the butterfly-shaped film sticks to the skin. In order to make the whole device fixed on various parts of the patient's body and fit the patient's skin better, the bottom of the butterfly-shaped film (8) is designed to be arc-shaped and sticky. The butterfly-shaped film (8) and the conduit clamping device (12) are pasted and detachable, so that the butterfly-shaped film is replaced regularly and the conduit clamping device can be used repeatedly.

The above description is a specific description of a feasible embodiment of the present invention. This embodiment is not intended to limit the protection scope of the present invention. All equivalent examples or changes that do not depart from the technical spirit of the present invention shall be included in the protection scope of the present invention middle.
