Description

Technical Field

[0001] This invention relates to the field of infusion early warning technology, and in particular to an infusion early warning device based on weight sensing and its usage method. Background Technology

[0002] Intravenous infusion therapy is a common treatment method that injects various drugs, including blood, into the bloodstream. Currently, in the treatment and rehabilitation of patients, intravenous infusion via sling is commonly used. During intravenous infusion via sling, patients or their families need to monitor the infusion at all times, or nurses need to make rounds. However, in actual treatment, problems may arise such as difficulty for patients to call for a doctor when receiving an infusion alone, patients falling asleep, too many patients for doctors to attend to, and different medications causing different reactions in patients, making it difficult to control the drip rate.

[0003] For example, a Chinese patent publication number CN211658933U discloses an infusion early warning device, including an alarm device. The alarm device includes a housing connected together by hinges. The housing has a closure latch and a closure protrusion. An infusion tube slot is provided on the inner wall of the housing. A microcontroller is installed inside the housing and connected to a battery. The battery has a charging port. The microcontroller is connected to a bubble detection sensor. The probe of the bubble detection sensor is located on the inner wall of the infusion tube slot. The microcontroller is connected to an electromagnet. The electromagnet has a spring clip embedded in the inner wall of the infusion tube slot. The inner diameter of the infusion tube slot matches the size of the infusion tube, allowing it to adhere well to the standard infusion tube. This provides early warning monitoring of the infusion tube. The internal bubble sensor detects the infusion status for quick early warning. The electromagnet drives the spring clip to close the infusion tube, providing protection and facilitating timely replenishment of infusions by medical personnel. This patent is worth promoting. However, this patent has the following problems: A bubble detection sensor is used to provide early warnings for infusion. However, in actual infusions, multiple bottles of medication are often delivered, requiring timely warnings and replacements. Once bubbles enter the infusion tubing, they are often difficult to expel directly, making it impossible to quickly replace the infusion bottle with a new one. Summary of the Invention

[0004] The purpose of this invention is to provide a weight-sensing-based infusion early warning device and its usage method to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an infusion early warning device and its usage method based on weight sensing, comprising a base, an adjusting support rod fixedly connected to the base, the adjusting support rod comprising a first support rod and a second support rod, the first support rod having an insertion hole at its upper end, the second support rod being slidably inserted into the insertion hole, a weight detection sensor fixedly connected to the upper end of the second support rod, a hanging top fixedly connected to the weight detection sensor, hooks fixedly connected in a row to the outer wall of the hanging top, and an information processing module fixedly connected to the outer wall of the second support rod, the information processing module being electrically connected to the second support rod.

[0006] Preferably, a bracket is fixed to the outer wall of the first support rod, and a handheld terminal is placed inside the bracket. The handheld terminal is electrically connected to the second support rod.

[0007] Preferably, the outer wall behind the first support rod is provided with a clearance groove, and the inner wall of the clearance groove is provided with a plurality of limiting holes.

[0008] Preferably, a threaded post is fixedly connected to the outer wall of the second support rod near the lower edge, and the threaded post slides in conjunction with the clearance groove.

[0009] Preferably, a retaining post is threadedly mounted on the threaded post, and a threaded mounting hole is provided at the end of the retaining post, the threaded mounting hole being threadedly engaged with the threaded post.

[0010] Preferably, a warning mechanism is fixedly connected to the outer wall of the second support rod, and the warning mechanism is electrically connected to the information processing module.

[0011] Preferably, the information processing module includes a central control module, a wireless transmission module, and a detachable power supply module.

[0012] Preferably, the warning mechanism includes a horn and an alarm light, both of which can be turned on and off independently to issue signals for warning.

[0013] The present invention also provides a method for using an infusion early warning device based on weight sensing, including the above-mentioned infusion early warning device for weight sensing, and further including the following steps: S1. Hang the infusion bottle or bag on the hook. Set a warning threshold based on the weight of the liquid in a single container, and then proceed with the infusion procedure as usual. S2. During the infusion process, the delivery of the drug solution will cause the suspended weight to gradually decrease. The weight reduction can be monitored by a weight detection sensor. When the weight decreases to the warning threshold, the warning mechanism can issue an audible and visual warning. S3. Medical staff confirm how much medication remains inside the container, and choose whether to replace it directly or wait for a period of time. After replacing the container connected to the infusion tube, repeat the threshold set in S to perform normal infusion operation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. By unscrewing the locking pin out of the limiting hole, you can hold the locking pin with your hand to move the second support rod, thereby easily adjusting the height of the hook, making it convenient for operators of different heights to hang medicine bottles and other containers onto the hook.

[0015] 2. The weight of the container is monitored by a weight detection sensor. As the medication is delivered into the patient's body, the amount of medication decreases, and the weight of the container also decreases. A monitoring threshold is set. When the overall weight of the container decreases to the threshold, the information processing module receives real-time information transmitted by the weight detection sensor and issues an early warning to medical staff to replace the medication bottle or remove the infusion needle in time.

[0016] 3. The detachable power supply module can provide power to the whole device, enabling the device to work normally without cables. The detachable handheld terminal makes it easy for users to perform operations such as threshold setting, making the device convenient for daily use.

[0017] 4. The horn and alarm light can be turned on and off independently. When the patient is in a state of avoiding stimulation, the light alone can be used for early warning. The warning methods are diversified and can be freely adjusted according to the usage environment. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-6 As shown, the present invention has the following specific embodiments.

[0022] Example 1 A weight-sensing-based infusion early warning device and its usage method include a base 101, an adjusting support rod fixedly connected to the base 101, the adjusting support rod including a first support rod 1 and a second support rod 2, the upper end of the first support rod 1 having an insertion hole 102, the second support rod 2 being slidably inserted into the insertion hole 102, a weight detection sensor 3 fixedly connected to the upper end of the second support rod 2, a hanging top 4 fixedly connected to the weight detection sensor 3, hooks 401 fixedly connected in a row to the outer wall of the hanging top 4, and an information processing module 204 fixedly connected to the outer wall of the second support rod 2, the information processing module 204 being electrically connected to the second support rod 2.

[0023] In this embodiment, the second support rod 2 is inserted into the insertion hole 102, thereby slidingly connecting the first support rod 1 and the second support rod 2 together to form an adjusting support rod, which adjusts the height of the upper hanging top 4, making it convenient for operators of different heights to hang medicine bottles and other containers onto the hook 401. The weight detection sensor 3 can monitor the weight of the suspended container. As the medicine is delivered into the patient's body, the amount of medicine decreases, and the weight of the container also decreases. The weight detection sensor 3 monitors the weight of the container. Based on the weight of the medicine stored inside the container, the set threshold weight needs to be slightly lower than the weight of the medicine. After the overall weight of the container decreases to the threshold, the information processing module 204 receives the real-time information transmitted by the weight detection sensor 3 and issues an early warning to the medical staff. At this time, a little medicine will remain inside the container, which allows the medical staff some time to come over, and at the same time prevents air from entering the infusion line, so that the medicine bottle cannot be directly replaced and the infusion can continue.

[0024] Example 2 A retainer 103 is fixedly connected to the outer wall of the first support rod 1. A handheld terminal 5 is held in the retainer 103 and electrically connected to the second support rod 2. A clearance groove 104 is provided on the outer wall of the rear of the first support rod 1. Several limiting holes 105 are arrayed on the inner wall of the clearance groove 104. A threaded post 201 is fixedly connected to the outer wall of the second support rod 2 near the lower edge. The threaded post 201 slides with the clearance groove 104. A retainer 202 is threadedly installed on the threaded post 201. A threaded mounting hole 203 is provided at the end of the retainer 202 and threadedly engages with the threaded post 201.

[0025] In this embodiment, the handheld terminal 5 is placed directly inside the card holder 103 and can be removed directly when in use. An existing mature human-machine interaction terminal is used, so it will not be described in detail. The threaded post 201 and the relief groove 104 slide together, allowing the threaded post 201 to extend through the first support rod 1 to the outside. The locking post 202 is threaded onto the threaded post 201. Tightening the locking post 202 allows its end to be inserted into the limiting hole 105. The limiting hole 105 and the locking post 202 cooperate with each other to restrict the second support rod 2 from moving up and down freely. When the locking post 202 is unscrewed out of the limiting hole 105, the second support rod 2 can be moved by hand by holding the locking post 202, thereby conveniently adjusting the height of the hook 401.

[0026] Example 3 The outer wall of the second support rod 2 is fixed with a warning mechanism 205. The warning mechanism 205 is electrically connected to the information processing module 204. The information processing module 204 includes a central control module, a wireless transmission module and a detachable power supply module. The warning mechanism 205 includes a horn and an alarm light, both of which can be turned on and off independently to send signals for warning.

[0027] In this embodiment, the early warning mechanism 205 is electrically connected to the handheld terminal 5 via wireless signal. The central control module processes the real-time gravity data monitored by the weight detection sensor 3, while the detachable power supply module provides power to the entire device, enabling the device to operate normally without cables. The wireless transmission module is used to transmit the monitored gravity data, and the early warning mechanism 205 includes a horn and an alarm light that can be turned on and off independently. When the patient is in a state of avoiding stimulation, the light alone can be used for early warning.

[0028] Working principle and usage process of this invention: S1. Hang the infusion bottle or bag on hook 401. Set a warning threshold based on the weight of the liquid in a single container, and then proceed with the infusion procedure normally. S2. During the infusion process, the delivery of the drug solution will cause the suspended weight to gradually decrease. The weight detection sensor 3 can monitor the decrease in weight. When the weight decreases to the warning threshold, the warning mechanism 205 can issue an audible and visual warning. S3. Medical staff confirm how much medication remains inside the container, and choose whether to replace it directly or wait for a period of time. After replacing the container connected to the infusion tube, repeat the threshold setting in S1 and perform normal infusion operation.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
