Description

Technical Field

[0001] This utility model relates to the field of timing technology, and in particular to a timer. Background Technology

[0002] The glucose tolerance test is an important laboratory test for diagnosing diabetes. This test primarily assesses pancreatic function and the body's ability to regulate blood glucose by detecting the blood glucose response after ingesting a certain amount of glucose. The oral glucose tolerance test is the most common method, and the procedure includes: drawing fasting venous blood in the morning to measure fasting blood glucose concentration; dissolving 75g of anhydrous glucose in 250-300ml of warm water and drinking it within 5 minutes; timing starting from the first sip of the glucose solution, and measuring blood glucose at 30 minutes, 1 hour, and 2 hours (sometimes including 3 hours). Because timing needs to begin from the first sip and tests need to be performed at regular intervals, especially when there are many patients, timing is difficult and prone to error.

If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0038] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0039] Reference Figure 1 , Figure 2 and Figure 5As shown, a timer 1000 according to one embodiment of this utility model can be used in a glucose tolerance test to achieve automatic timing and an alarm after a certain interval. The timer 1000 of this utility model includes a base 100, a control component (not shown), a water level sensor 300, and an alarm 400. The upper end of the base 100 has multiple upwardly extending limiting posts 110, which are elongated columnar in shape. The multiple limiting posts 110 are spaced apart circumferentially along the base 100, and a limiting space 120 for accommodating a cup 500 is formed between the upper surface of the base 100 and the multiple limiting posts 110. The cup 500 can be a transparent glass cup or a cup 500 specially customized according to the size of the timer 1000. The cup 500 is inserted into the limiting space 120 from top to bottom, and the limiting posts 110 engage and limit the cup 500, effectively preventing the cup 500 from separating from the base 100.

[0040] Reference Figure 2 As shown, the base 100 has a slot 130 on its side wall, with the opening of the slot 130 located on the side wall of the base 100. A control component is located inside the base 100 and includes a connector 200 located on the side wall of the slot 130. A water level sensor 300 is located on the side of the limiting post 110 facing the limiting space 120. The water level sensor 300 is used to detect the water level inside the cup 500; for example, it can be a photoelectric liquid level sensor or a capacitive liquid level sensor, monitoring changes in water level in a non-contact manner. An alarm 400 is detachably connected to the slot 130 and electrically connected to the connector 200. The control component acquires the water level information detected by the water level sensor 300 and enables the alarm 400 to sound an alarm after a set time period. Alarm types may include audible alerts, vibration, flashing lights, and voice announcements.

[0041] Understandably, by adopting the above scheme, the water level sensor 300 is used to detect the water level inside the cup 500. For example, the water level will drop after the user drinks water, which can be detected by the water level sensor 300. After the control component obtains the corresponding water level information, it causes the alarm 400 to start automatically timing, and the alarm 400 can automatically sound an alarm after a set time period, such as once after half an hour, one hour, and two hours. Therefore, the timer 1000 can automatically time according to the change in the water level inside the cup 500, and automatically sound an alarm through the alarm 400 at the set interval. Since the alarm 400 is detachably connected to the slot 130, after the alarm 400 automatically times, it can be removed and carried by the corresponding medical staff so that they can hear the alarm immediately. When there are multiple patients, multiple timers 1000 can be used, and each timer 1000 can be labeled accordingly, for example, the base 100 and the alarm 400 can be labeled with the same label, so as to facilitate comparison of which patient's alarm 400 is being used, thereby improving the accuracy of the test.

[0042] Reference Figure 2 and Figure 4 As shown in the embodiment of this utility model, the bottom wall of the slot 130 is provided with one of the guide grooves 131 or guide ribs 410, and the bottom wall of the alarm 400 is provided with the other of the guide grooves 131 or guide ribs 410. The guide ribs 410 can be inserted into the guide grooves 131. For example, the bottom wall of the slot 130 is provided with multiple guide grooves 131 at intervals, and the bottom wall of the alarm 400 is provided with multiple guide ribs 410 at intervals. The combination of multiple guide ribs 410 and guide grooves 131 can improve the accuracy and stability of guidance, which is beneficial to the alignment and engagement of the interface 460 of the alarm 400 and the connector 200 of the control component, and improves the accuracy of engagement between the alarm 400 and the slot 130.

[0043] As an alternative embodiment, in another embodiment of the present invention, the upper wall of the slot 130 is provided with one of the guide groove 131 or the guide rib 410, and the upper wall of the alarm 400 is provided with the other of the guide groove 131 or the guide rib 410, and the guide rib 410 can be inserted into the guide groove 131.

[0044] Reference Figure 2 As shown in the embodiment of this utility model, along the direction close to the center of the base 100, the opening width of the guide groove 131 at the outer end gradually decreases. It can be understood that the gradual reduction in the opening width at the outer end of the guide groove 131 facilitates the quick alignment of the guide rib 410 and the guide groove 131, improves positioning efficiency, and reduces the need for repeated disassembly and assembly by the user.

[0045] To facilitate determining the operational status of the alarm 400, refer to... Figure 2As shown in the embodiment of this utility model, the alarm 400 includes an indicator light 420, which is exposed on the surface of the alarm 400. The indicator light 420 is connected to a controller inside the alarm 400 and is used to flash when the alarm 400 sounds. It is understandable that when medical staff are holding multiple alarms 400 for different patients simultaneously, it is difficult to immediately determine which alarm 400 is ringing if only sound is provided. Therefore, by setting the indicator light 420 to flash when the alarm sounds, medical staff can easily locate the alarm 400 that is ringing. Specifically, the indicator light 420 can remain constantly lit when the alarm 400 is working normally, and turns off when the alarm 400 stops working. Therefore, it is easier for medical staff to judge the working status of the alarm 400, improving the user experience.

[0046] A constantly blaring 400 alarm can be very annoying; therefore, please refer to... Figure 2 As shown in the embodiment of this utility model, the alarm 400 includes a switch 430 exposed on the surface of the alarm 400. The switch 430 is electrically connected to a controller inside the alarm 400. The switch 430 is used to turn off the alarm when the alarm 400 sounds. It is understood that by setting the switch 430, the alarm can be turned off by pressing the switch 430 after hearing it, avoiding prolonged alarm noise from disturbing other patients' rest and also avoiding the irritability caused by prolonged alarm noise. By pressing and holding the switch 430, the alarm 400 can be forcibly turned on or off to meet the needs of different situations.

[0047] To facilitate medical staff carrying the alarm device 400, therefore, we will continue to refer to... Figure 2 As shown in the embodiment of this utility model, the side wall of the alarm 400 is provided with a connecting ring 440, and the connecting ring 440 and the outer shell of the alarm 400 are integrally formed. The connecting ring 440 can connect to structures such as straps 470 and metal rings, thereby facilitating medical personnel to remove the alarm 400 from the slot 130 and carry it, reducing the probability of the alarm 400 becoming loose and falling off, and improving the user experience.

[0048] For easy disassembly of alarm 400, please refer to... Figure 1 As shown in the embodiment of this utility model, when the alarm 400 is engaged in the slot 130, two bevels are provided at the two corners of one end of the alarm 400, thus forming a hand-holding groove 450 between the alarm 400 and the base 100. Two hand-holding grooves 450 are formed, located on opposite sides of the alarm 400. To remove the alarm 400, simply insert your finger into the hand-holding groove 450 and then remove it; the operation is simple and convenient. To further improve the success rate, anti-slip pads can be provided on the bevels to increase friction and reduce slippage.

[0049] In this embodiment of the invention, a first rechargeable battery is housed in the base 100, and a second rechargeable battery is housed in the alarm 400. The first rechargeable battery can charge the second rechargeable battery via the connector 200. It is understood that because the alarm 400 is small and its battery capacity is insufficient, using the first rechargeable battery in the base 100 to charge the second rechargeable battery in the alarm 400 can increase the alarm 400's usage time and improve the user experience. The base 100 can be equipped with a charging interface 460, allowing it to be placed on a table for charging at any time.

[0050] Reference Figure 2 As shown in the embodiment of this utility model, the limiting post 110 is elastically deformable, and an elastic protrusion 111 is provided on the upper end of the limiting post 110 facing the limiting space 120. The elastic protrusion 111 is used to abut against the side wall of the cup 500. The elastic protrusion 111 can be a rubber part or a silicone part, which can increase the friction with the side wall of the cup 500 to reduce the risk of separation between the cup 500 and the base 100.

[0051] Reference Figure 2 and Figure 3 As shown in the embodiment of this utility model, the water level sensor 300 is a photoelectric liquid level sensor, which includes a transmitter 320 and a receiver 310. The transmitter 320 is disposed on one side of one of the limiting posts 110 facing the limiting space 120, and the receiver 310 is disposed on the opposite side of the other limiting post 110 facing the transmitter 320. When the water level in the cup 500 rises or falls, it changes the optical path between the transmitter 320 and the receiver 310, thereby triggering the photoelectric liquid level sensor to output a corresponding signal. The photoelectric liquid level sensor has the characteristics of low power consumption, high accuracy, and resistance to jamming.

[0052] As an alternative embodiment, the water level sensor 300 can also be a capacitive level sensor, which measures the liquid level by detecting changes in capacitance between the liquid and the sensor probe. Although it requires close contact with the outer wall of the container to achieve liquid level detection, it can also be considered a non-contact detection method (because the sensor probe does not directly contact the water). When the liquid level approaches the sensor probe, the parasitic capacitance of the liquid couples to the static capacitance of the probe, causing a change in capacitance value. This changing capacitance signal, after conversion and processing, yields the liquid level information.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
