Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a PVC soft bag with a reminder device. Background Art

[0002] PVC soft bags can be used to store and transport liquid medicines, such as saline and glucose solutions. They are highly transparent and easy to observe the internal conditions. No air is required during use, which can prevent bacteria and particles in the air from contaminating the liquid medicine. Simple PVC soft bags lack a convenient reminder device. During use, medical staff need to pay attention to the progress of infusion at all times, which affects other work and brings inconvenience to medical staff. In addition, for patients, it will also affect the quality of rest. Therefore, it is of practical application value to develop a PVC soft bag with a reminder device that sends a reminder when the internal liquid is running out. Utility Model Content

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A PVC soft bag with a reminder device comprises a transparent bag body, a short-range reminder and a long-range reminder. A hook is arranged on the upper part of the transparent bag body, and a weighing sensor is arranged between the two. The weighing sensor is connected to a control circuit, and the control circuit is connected to the short-range reminder by wire and to the long-range reminder by wireless. Vibration devices are arranged in both the short-range reminder and the long-range reminder. A downward-facing illumination lamp is arranged on the upper part of the transparent bag body.

[0006] Furthermore, the vibration device includes a motor, the rotating shaft of the motor is connected to a bias block, the body of the motor is connected to a direction conversion mechanism, the direction conversion mechanism includes a worm wheel and a worm arranged in a cross-meshing manner, the worm wheel is connected to the motor through a shaft, and the worm is connected to a knob.

[0007] Furthermore, a reflector is arranged outside the irradiation lamp, and the opening of the reflector faces the transparent bag body.

[0008] Furthermore, the wiring between the control circuit and the proximity reminder is provided with a spiral curling section, and both ends of the wiring are pluggable connectors.

[0009] Furthermore, the knob is exposed outside the short-range reminder and the long-range reminder.

[0010] Furthermore, the transparent bag body is made of soft material, and the edges are sealed by fusion, wherein the upper edge is connected to the hook via a weighing sensor.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model monitors the mass change of the liquid in the transparent bag in real time by arranging a weighing sensor. When the mass value reaches the set value, the control system sends a signal to the short-range reminder and the long-range reminder. The vibration devices in the two devices vibrate for prompting without making any sound, so it will not affect other people around. It is suitable for use in an environment that requires quietness. The illumination light is turned on to facilitate the plugging and unplugging of the lower needle head. In addition, the vibration direction of the vibration device can be adjusted as needed, and can be switched between the vertical direction and the horizontal direction.

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] like Figure 1-2As shown, a PVC soft bag with a reminder device includes a transparent bag body 1, a short-range reminder 2 and a long-range reminder 3. The transparent bag body 1 made of PVC material is convenient for observing the internal liquid medicine. No air is required during use, which can prevent the liquid medicine from being contaminated by bacteria and particles in the air. The edge is sealed by fusion, and the upper edge is connected to the hook 1a through a weighing sensor. A weighing sensor is arranged between the transparent bag body 1 and the hook 1a. The weighing sensor is connected to a control circuit. When a load acts on the weighing sensor, the elastic body of the weighing sensor undergoes a slight change, thereby causing the resistance value of the resistance strain gauge attached to the elastic body to change. Changes change the balance of the bridge and change the output voltage. The changed voltage signal is amplified, filtered, and converted into a digital signal by A / D. The signal is collected and input into the control system. The control circuit is connected to the short-range reminder 2 by wire and to the long-range reminder 3 by wireless. Both the short-range reminder 2 and the long-range reminder 3 are provided with a vibration device 4. A downward-facing irradiation lamp 5 is provided on the upper part of the transparent bag body 1. A reflector is provided outside the irradiation lamp 5. The opening of the reflector faces the transparent bag body 1. The transparent bag body 1 is made of soft material. The edge is sealed by fusion. The lower edge is connected to a liquid outlet interface. When the irradiation lamp 5 is turned on, it can provide lighting through the bag body to facilitate the insertion and removal of the lower needle head.

[0018] For ease of use, the vibration direction of the vibration device 4 can be adjusted. Specifically, the vibration device 4 includes a motor 4a, the rotating shaft of the motor 4a is connected to a bias block 4b, the body of the motor 4a is connected to a direction conversion mechanism 4c, the direction conversion mechanism 4c includes a worm wheel 4c-1 and a worm 4c-2 that are cross-engaged, the worm wheel 4c-1 is connected to the motor 4a through an axis, and the worm 4c-2 is connected to a knob 4c-3; the knob 4c-3 is exposed outside the short-range reminder 2 and the long-range reminder 3, and by rotating the knob 4c-3, the motor 4a can be rotated through the worm gear mechanism, thereby changing the vibration direction and switching between the vertical direction and the horizontal direction. The worm wheel 4c-1 and the worm 4c-2 mechanism are self-locking, that is, the worm wheel 4c-1 can only be driven by the worm 4c-2.

[0019] The wiring between the control circuit and the proximity reminder 2 is provided with a spiral curling section to facilitate the extension of the wiring. Both ends of the wiring are pluggable connectors and both ends can be disconnected to improve ease of use.

[0020] The utility model discloses a PVC soft bag with a reminder device, which monitors the mass change of the liquid in a transparent bag body 1 in real time through a weighing sensor. When the mass value reaches a set value, the control system sends a signal to a short-range reminder 2 and a long-range reminder 3. A vibration device 4 in the two devices vibrates for reminder without sound, so it will not affect other people around. The utility model is suitable for use in a quiet environment. The illumination light 5 is turned on to facilitate the plugging and unplugging of the lower needle head. In addition, the vibration direction of the vibration device 4 can be adjusted between the vertical direction and the horizontal direction as needed.

[0021] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, relevant changes, modifications or additions should all fall within the protection scope of the utility model.
