Description

A Gravity Detection Type Infusion Alarm

technical field

The utility model relates to the technical field of medical care appliances, in particular to a gravity detection type infusion alarm for patients during infusion.

Background technique

Infusion is a routine means to treat patients clinically. At present, most of the infusion devices used in the hospital are to hang the infusion bottle or the infusion bag on the infusion stand, and perform the infusion operation to the patient through the infusion tube. Its main disadvantage is that during the infusion process of the patient, it is usually necessary for the nurse or the family members of the patient to manually observe whether the liquid medicine has been delivered, and then notify the nurse in time to perform operations such as changing the dressing and pulling out the needle. When the liquid in the infusion bottle is delivered, if no one is watching or the patient falls asleep during the infusion, and for some patients with long-term bedridden mobility, they cannot find that the liquid medicine has been delivered in time, or sometimes the nurse is tired or negligent. If the infusion needle is not pulled out in time or a new infusion bottle is replaced for other reasons, this will lead to air intake in the infusion tube, which will easily cause medical accidents such as gas entering the vein or blood backflow. This situation not only brings great pain and even life-threatening to patients, but also increases the workload of nurses.

At present, some infusion devices with alarm function have also appeared on the market, but most of them are directly arranged on the infusion device as a part of the infusion device. Because the infusion device is basically disposable, it not only greatly increases the The manufacturing cost of the infusion set also causes huge waste. Simultaneously, the existing infusion alarm device only has the function of alarm prompt, and cannot have the function of automatically stopping the infusion to avoid danger in case of emergency.

Utility model content

The technical problem to be solved by the utility model is: to provide a gravity detection type infusion alarm that can be used repeatedly, and can realize real-time monitoring of the infusion process, and is low in cost, and can automatically clamp and stop the infusion when the infusion is completed. To reduce the workload of medical care and reduce the occurrence of medical accidents.

The technical scheme adopted by the utility model to solve the above technical problems is: a gravity detection type infusion alarm, which is provided with a housing, a spring is vertically fixed inside the housing, and the bottom end of the spring is connected with an extension A hook for hooking the infusion device out of the casing, the lower part of the spring is provided with an induction contact block, and a plurality of upper and lower sidewalls in the housing are sequentially provided with the induction contact block respectively to form a close The positioning sensor of the switch, the positioning sensors are all set within the range that the sensing contact block moves with the deformation of the spring, and except for the positioning sensor located at the uppermost end of the side wall of the housing, the rest of the positioning sensors and the sensing contact block constitute The proximity switch is a time-delay switch, and the outer surface of the housing is also provided with a speaker and a prompt lamp electrically connected to the positioning sensor, and a device for clamping the infusion tube is also provided on the infusion tube connected under the infusion device. A clamp to cut off the flow, the clamp is electrically connected to a positioning sensor located at the uppermost end of the side wall of the casing.

The infusion device is an infusion bottle or an infusion bag.

Both the loudspeaker and the prompt light are powered by a battery arranged in the casing.

Beneficial effect:

A gravity detection type infusion alarm of the utility model has the characteristics of simple structure, reasonable design, convenient use and the like. The alarm device can give a real-time alarm reminder to the progress of the infusion during the infusion process, and can also automatically clamp the infusion tube to stop the infusion when the infusion is completed, so that there is no need to pay attention to the infusion process frequently during the infusion process, thus reducing the work of medical staff amount and reduce the occurrence of medical accidents. The whole device has a high degree of automation, low cost, and can be reused many times, which provides great convenience for clinical infusion and has high market value.

detailed description

The specific embodiment of the utility model is described below in conjunction with accompanying drawing:

A gravity detection type infusion alarm is provided with a housing 1, a spring 2 is vertically fixed inside the housing 1, and a spring 2 is connected to the bottom end of the spring 2 to extend out of the housing 1 for hooking an infusion device 3 the hook 4, the infusion device 3 is an infusion bottle or an infusion bag, the lower part of the spring 2 is provided with an induction contact block 5, and the side wall of the housing 1 is sequentially provided with a plurality of The sensing touch block 5 cooperates to form a positioning sensor 6 of a proximity switch, and the positioning sensors 6 are all arranged within the stroke range that the sensing touch block 5 travels during the infusion of the infusion device 3 all the time, and except for the positioning sensor located in the housing 1 Except for a positioning sensor 6 at the uppermost end of the side wall, the proximity switch formed by the rest of the positioning sensors 6 and the inductive contact block 5 is a time-delay switch. The outer surface of the housing 1 is also provided with a speaker electrically connected to the positioning sensor 6 7 and a reminder light 8, the speaker 7 and the reminder light 8 are powered by a battery arranged in the housing 1, and an infusion tube 9 connected below the infusion device 3 is also provided with a device for clamping the infusion tube 9 to make it The shut-off clamp 10 is electrically connected to a positioning sensor 6 located at the uppermost end of the side wall of the casing 1 .

When the gravity detection type infusion alarm of the present utility model is used specifically, the infusion device, that is, the infusion bottle or the infusion bag is hung upside down on the hook at the end of the spring. At this time, the spring in the housing is pulled by the gravity of the infusion device. Extending to the maximum length, that is, the horizontal position of the sensing contact block at the lower part of the spring is lower than the horizontal position of the positioning sensor located at the bottom of the housing side wall. At this time, the infusion alarm is turned on through the switch provided on the housing. During the infusion process, as the liquid in the infusion device decreases continuously, the spring in the housing will continuously shrink upwards. A total of 4 positioning sensors are arranged on the side wall of the casing, and these 4 positioning sensors correspond to the remaining liquid volumes in the infusion device in turn of 250ml, 100ml, 20ml and 5ml from bottom to top. When the inductive contact block on the spring continuously rises to the corresponding positioning sensors of 250ml, 100ml and 20ml with the continuous decrease of the liquid in the infusion device, the corresponding positioning sensor and the inductive contact block form a proximity switch, and the control circuit is connected to realize The sound and light alarm of the loudspeaker and the prompt light in the device reminds the medical staff or patients to pay attention to the progress of the infusion. At the same time, the proximity switches formed by the three positioning sensors and the sensing touch block are time-delay switches, that is, the proximity switches control the speakers and prompts. The light will automatically disconnect after a period of sound and light alarm. When the sensing block on the spring rises to the positioning sensor corresponding to the 5ml remaining liquid, the corresponding positioning sensor will not only form a proximity switch with the sensing block, control the speaker and the indicator light for a long time sound and light alarm, but also control The clamp on the infusion tube realizes the clamping of the infusion tube to cut off the flow and stop the infusion to the patient.

The utility model relates to a gravity detection type transfusion alarm, which has simple structure, ingenious design, and is simple and practical. It not only effectively reduces the burden on patients and bed companions, reduces the workload of medical staff, but also effectively reduces the occurrence of medical accidents.
