Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

The utility model is suitable for the technical field of medical devices, mainly through the combination of liquid level detection and alarm cut-off, aiming at the near-completion stage of the infusion, by monitoring the drop of the liquid level in the infusion tube, the alarm is triggered in time to remind the medical staff to handle in place in time, and the infusion The tube is cut off to buffer the waiting time and avoid air entering the blood vessel when the infusion liquid is directly infused when the medical staff is not in place in time.

As shown in Figure 1, the utility model provides an infusion liquid level detection and alarm mechanism, including a frame 6 for holding a drip pot, the bottom and top of the frame 6 are provided with grooves for placing the drip pot and Keep the dripping pot in a vertical state, the dripping pot is placed in the frame 6, and the upper and lower ends are straightened through the grooves to ensure that the dripping pot is placed in the same direction as the frame 6, and both are in a vertical position. Direction, the mounting base 1 is installed on the outside of the frame 6, and the liquid level sensor 2 is hoisted on one side of the mounting base 1 through the bending rod 5, and the sound and light alarm 3 is installed on the other side of the mounting base 1, and A shut-off clamp 4 is connected to the side wall of the mounting base 1, and a controller and a power supply are arranged in the mounting base 1. The controller is electrically connected with the sound and light alarm 3, the liquid level sensor 2 and the shut-off clamp 4, and the power supply is connected with the power supply. The sound and light alarm 3, the liquid level sensor 2 and the shut-off clip 4 are electrically connected and powered.

Wherein, the liquid level sensor 2 is arranged inside the infusion dripping pot, the sound and light alarm 3 is arranged outside the infusion dripping pot, the shut-off clamp 4 is arranged around the drip funnel in the circumferential direction and the end of the shut-off clip 4 and the mounting seat 1 are positioned on the infusion tube The opposite side of the drip pot.

The mechanism for detecting liquid level and alerting shutoff is:

The liquid level alarm height value is preset in the controller, and the liquid level sensor 2 (the liquid level sensor 2 adopts a contact sensor) detects the height of the liquid level in the dropping pot in real time and transmits the detection information to the controller. When the surface height reaches the set liquid level alarm height value, the controller triggers the sound and light alarm 3 to alarm, and sends an instruction to the closure clip 4, so that the closure clip 4 shrinks and clamps to squeeze the dripping pot to stop the flow.

The alarm sound reminds the nursing staff to take timely measures. At the same time, 4 pairs of shut-off clamps squeeze and shut off the drip pot, as shown in the schematic diagram of squeeze in Figure 2. The squeeze part separates the lower part of the infusion tube from the top air part, so that the liquid part in the infusion tube The infusion needle communicates with the human blood vessel environment and maintains the same pressure, which will not cause blood to flow back into the infusion tube, and will not cause air to enter the infusion tube, so as to gain reaction time for medical staff.

The liquid level sensor 2 is made into a micro-probe type and installed inside the drip pot so as to detect the change of liquid level more sensitively. 5 is made into an L shape, and the bending rod 5 is bent downward so that the liquid level sensor 2 is arranged at the bottom of the dripping pot and close to the side of the mounting base 1, and the liquid level sensor 2 can detect a larger range of liquid level before reaching an alarm Threshold, and the shut-off clamp 4 is set above the liquid level sensor 2 to squeeze the dripping pot, avoiding the height of the liquid level sensor 2, and avoiding the liquid level sensor 2 from causing incomplete extrusion and shut-off.

There are many kinds of extrusion directions for the clip 4 to squeeze the dripping pot. In order to completely intercept the flow, the present embodiment uses the mounting base 1 as the extrusion back plate to perform the extrusion and closure operation. Specifically, as shown in Figures 1 and 3, The shut-off clip 4 includes a main control seat 41 installed on the mounting base 1 , a pair of movable arm clamps 42 are installed on the main control seat 41 , and a pushing plate 43 is installed at the ends of the movable arm clamps 42 .

The clamping mechanism of the shut-off clip 4 is similar to the action mechanism of the existing disclosed mechanical claw (hand). The main control seat 41 is fixedly installed on the mounting seat 1, and the movable arm clips 42 on both sides are arranged on the opposite sides of the drip pot; The plate 43 is arranged in parallel with the mounting seat 1, and the pushing plate 43 and the mounting seat 1 are arranged on opposite sides of the dripping pot, and the movable arm clamp 42 is stretched and contracted under the control of the main control seat 41 to drive the pushing plate 43 to move so as to squeeze Pressure drip pot.

The movable arm clamp 42 is set in the form of a telescopic rod, and a control unit and a driving mechanism for driving the telescopic movement of the movable arm clamp 42 are arranged in the main control seat 41, which can realize telescopic movement and reset. There are many control methods, which will not be described in detail here.

In order to avoid sharp damage to the drip pot when squeezed, a soft film 44 is provided on the side of the push plate 43 close to the drip pot in this embodiment. The soft film 44 is made of flexible rubber material, and the soft film 44 wraps the push plate 43 The edges and corners avoid sharp edges and corners from poking and damaging the dripping pot.

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be deemed to fall within the protection scope of the present application.
