Technical Field

[0001] The utility model relates to the field of nursing, in particular to a warning device for reminding people to check or pay attention to the possibility that liquid medicine may be exhausted. Background Art

[0002] In the field of nursing, liquids with medicinal or therapeutic properties are delivered to a patient's body by injection or drip. During drip, the flow of liquid can be controlled. Usually, an experienced nurse can predict the approximate time and perform dressing changes or end operations before the liquid drips out.

[0003] Due to the shortage of medical personnel, the nurse needs to take care of multiple patients. Therefore, the general precautions are informed to the patient's family or caregiver, and the nurse will go to take care of other people. However, due to deep sleep or inexperience, the family or caregiver neglects to notice that the liquid is about to run out. It is not until they wake up or realize that there is no liquid that they think of notifying the nurse to deal with it. Because of the delay in time, it may cause irreparable physiological damage, such as: bruising, swelling or infection.

[0004] During the drip period, how to reduce the physiological harm to the patient and alleviate the psychological burden of the family members or caregivers has become an urgent problem to be overcome in the present invention. Utility Model Content

[0024] Unless otherwise stated, in the following description, "a plurality of" means two or more.

[0025] Figure 1 In, a packaging container stores a volume of liquid 41. In this embodiment, the packaging container is a bag 40. The bag 40 is enclosed around, and it has an outlet (not labeled) that can be connected to a hose 43. The hose 43 guides the liquid 41 to a patient (not shown in the figure).

[0026] In some embodiments, the packaging container is a bottle (not shown in the figure), and the mouth of the bottle is connected to the hose 43, and can also convey the liquid 41 to the patient.

[0027] A bracket 44 has two arms 45. The bracket 44 stands on a support surface (not shown in the figure), such as the ground. The arms 45 maintain a height from the support surface. One end of a tension spring 54 is hooked to the arm 45, and the other end is hooked to the bag 40. A pulling force of the tension spring 54 counteracts the gravity of the liquid 41, causing the bag 40 to hang on the arm 45 and supporting the hose 43 to droop along the side of the bracket 44.

[0028] A flow regulator 42 is installed on the hose 43, which changes the cross-sectional area of the local pipe body, thereby operating the dripping speed of the liquid 41 through the hose 43.

[0029] In order to sense the reduction or near exhaustion of the amount of the liquid 41, the present utility model employs a warning device to perform inspection or detection, generating a warning effect through an acoustic and optical effect to remind the family members or caregivers of the patient to pay attention and immediately notify a caregiver to come and handle it.

[0030] In the first embodiment, the warning device includes, but is not limited to: a container 10, a detection unit, and a warning system.

[0031] Among them, the container 10 has four connected walls 11, enclosing a rectangular chamber 12 that is open at the top and bottom. The walls 11 are transparent, allowing the situation inside the chamber 12 to be clearly seen. The container 10 also has a bottom plate 15 and two ropes 17. The two ropes 17 are tied to two parallel walls 11 to be able to hang the arm 45, causing the container 10 to droop along the side of the bracket 44. The bag 40 is placed inside the chamber 12, and each wall 11 surrounds the bag 40. The bottom plate 15 is a rectangular ring body, which has a hollow portion 16 (see Figure 2 ) connected to the chamber 12 for the hose 43 to extend out of the container 10.

[0032] In some embodiments, the container 10 has a geometric shape such as a sphere or a cylinder, so the number of the walls 11 is at least one. At the same time, the shape of the bottom plate 15 and / or the hollow portion 16 is the same as or similar to the shape of the container 10.

[0033] In this embodiment, the detection unit includes, but is not limited to: four contact parts 14 (see Figure 2 )、a load plate 21, and four permanent magnet groups 50, 51, 52, 53.

[0034] Among them, the four contact parts 14 are at the four corners of the container 10. The contact parts 14 are fixed between the two walls 11, and the distance (or height) from the contact parts 14 to the bottom plate 15 remains unchanged.

[0035] A hole 22 is formed in the center of the load board 21. An electronic circuit 23 is arranged on one side of the load board 21 and has four contact points 24 (see Figure 2 ). The load board 21 is placed in the chamber 12 between the contact part 14 and the bottom board 15, and it is preferred that the contact points 24 face the contact part 14. Since the outlet (or bottle mouth) of the bag 40 is combined with the hole 22, the load board 21 moves together with the bag 40 and becomes one of the heavy objects hooked by the tension spring 54.

[0036] According to the phenomenon of opposite-sex attraction, the permanent magnet group 50 firmly holds the corresponding contact part 14, and the permanent magnet group 51 is distributed on the top surface of the load board 21. According to the phenomenon of same-sex repulsion, the permanent magnet group 52 firmly holds the bottom surface of the load board 21, and the permanent magnet group 53 is distributed at the corresponding position of the bottom board 15.

[0037] From Figure 2 It is not difficult to find that the warning system in this embodiment includes, but is not limited to: four wires 13, a controller 30, a sound effect unit 31, a light effect unit 32 and a communication device 34.

[0038] Among them, the wire 13 connects the contact part 14 to the controller 30. The contact part 14 protrudes a conductive protruding point (not labeled) towards the bottom board 15.

[0039] In this embodiment, the controller 30 is electrically connected to the sound effect unit 31, the light effect unit 32 and the communication device 34. The so-called electrical connection is divided into two technical means: wired transmission and wireless transmission 33. For the said wired transmission technology, other wires 13 are used to connect the sound effect unit 31 or the light effect unit 32 to the controller 30. For the said wireless transmission 33 technology, without passing through conductive substances, the controller 30 and the communication device 34 use the following agreements to transmit a message, such as: Wi-Fi, Bluetooth, Li-Fi, NFC, RFID, Z-Wave, LTE-A, 5G, LPWAN, VSAT, etc. In addition, a power unit (not shown in the figure) is configured inside the controller 30 to supply power to the entire warning system.

[0040] Among them, the sound effect unit 31 refers to a buzzer, a speaker or other appliances or devices that can produce sound effects.

[0041] Among them, the light effect unit 32 is a light bulb, a light-emitting diode (LED) or other appliances or devices that can produce brightness (or luminance).

[0042] Among them, the communication device 34 can be a smart phone installed with an application (abbreviated as App) or other communication devices.

[0043] Cooperate Figure 1 、 Figure 2 It is known that with the support of the tension spring 54, the more the amount of the liquid 41, the closer the load plate 21 is to the bottom plate 15; when the amount of the liquid 41 decreases or even runs out, the load plate 21 is closer to the contact part 14. Thus, the load plate 21 responds to the gravity of the liquid 41 and becomes the main body for inspection or detection.

[0044] The magnetic force of one of the two permanent magnet groups 50, 51 generates an attracting effect to counteract the gravity of the liquid 41. Since the gravity of the load plate 21 remains unchanged, the load plate 21 approaches the contact part 14, reacting to the possibility that the amount of the liquid 41 decreases or even runs out. The gravity of the bag 40 becomes lighter and lighter, and the attracting magnetic force multiplies the pulling force on the tension spring 54 to jointly lift the bag 40. The height of the bag 40 from the bottom plate 15 gradually increases, relatively reducing the distance between the load plate 21 and the contact part 14.

[0045] The magnetic forces of the two permanent magnet groups 52, 53 generate a repulsive effect, which can also counteract the total gravity of the load plate 21 and the liquid 41. Thus, the repulsive magnetic force acts on the load plate 21 to assist the pulling force of the tension spring 54 to lift the bag 40 together.

[0046] As the load plate 21 moves closer to the contact part 14, the contact point 24 touches the contact part 14 (such as a protruding point), causing the electronic circuit 23 to conduct current to generate a signal (such as voltage), which is fed back to the controller 30 via the wire 13 to complete a physical inspection or detection operation.

[0047] Based on the signal, the controller 30 actuates the sound effect unit 31 to generate a sound to remind the family member or caregiver of the patient to pay attention to the fact that the amount of the liquid 41 decreases to a possible exhaustion, and to notify the caregiver to come and handle it as soon as possible, such as changing the dressing or ending the drip operation. Therefore, the present utility model has a warning function.

[0048] Alternatively, based on the signal, the controller 30 actuates the light effect unit 32 to generate a beam of light, which can also remind the family member or caregiver of the patient to pay attention to the situation that the amount of the liquid 41 decreases to a possible exhaustion.

[0049] Or, the controller 30 can also, based on the signal, actuate the communication device 34 of the caregiver to open the App to generate a short message to remind the caregiver to go to the location of the patient to handle the subsequent matters of the possible exhaustion of the liquid 41.

[0050] Such as Figure 2 、 Figure 3As shown, the composition of the second embodiment of the warning device is substantially the same as that of the first embodiment. The difference is that the detection unit does not have a permanent magnet group.

[0051] Secondly, the detection unit has an additional set of compression springs 20. This set of compression springs 20 abuts against the bottom plate 15 and pushes the load plate 21 to counteract the gravity of the liquid 41. Therefore, the thrust of this set of compression springs 20 cooperates with the pulling force of the tension spring 54 to gradually move the load plate 21 away from the bottom plate 15. The contact point 24 touches the contact part 14 (such as a protruding point), allowing current to pass through the electronic circuit 23 to generate a signal to the controller 30, completing the inspection or detection of the gravity of the bag 40.

[0052] Without departing from the broad concept of the present invention, those skilled in the art can understand and make changes to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed in the specification. Any modifications made according to the spirit and technical scope of the present invention should be covered and protected by the literal content defined by the claims.
