Description

Technical Field

[0001] The invention relates to the technical field of infusion warning, and in particular to a drip warning device. Background Art

[0002] In modern medical treatment, intravenous drip infusion and drug injection are widely used. However, at the end of intravenous drip injection, the hydraulic pressure in the injection tube will suddenly decrease due to the gradual exhaustion of the intravenous drip liquid, which will cause the blood to flow back from the injection needle due to insufficient hydraulic pressure. What's worse, when the intravenous drip liquid is completely used up, the air in the injection tube may flow into the patient's blood vessels, causing medical troubles, inconveniences and even endangering the safety of patients. Therefore, during the intravenous drip injection, manual visual supervision is often required to monitor whether the intravenous drip infusion has been completed to avoid the above situation.

[0003] However, the manual monitoring method is labor-intensive, and in the absence of family members to accompany the patient, the patient may become drowsy and fall asleep during the infusion alone, and thus cannot observe in time whether the drip infusion has been completed. Therefore, an alarm device for real-time monitoring of whether the drip infusion has been completed has been developed. However, the device can only sound an alarm, but cannot block the liquid or air in the infusion tube in time. During some peak periods, medical staff cannot help patients replace the infusion bottle in time, resulting in the risk of blood return. The existing structure for blocking the infusion tube is arranged at a higher position. When used by patients with limited mobility after surgery, it is not convenient for the patients to operate the blocked infusion tube themselves. Therefore, the present application provides a drip alarm to meet the demand. Summary of the invention

The second buffer cavity 23 opened on the fixing frame 1 enables the inner wall of the fixing frame 1 to better squeeze the second limiting buckle 4, so that when the second limiting buckle 4 is retracted in the limiting groove 14, it can be better retracted and squeezed inward, and the limiting pressing frame 17 is pressed into the second limiting buckle 4, so that the limiting pressing frame 17 further squeezes the infusion tube in the second limiting buckle 4, so that the infusion tube in the second limiting buckle 4 is quickly locked, and the first buffer cavity 18 is used. The opening enables the limiting pressure frame 17 to have a better squeezing effect on the infusion tube in the second limiting buckle 4, and the opening of the fourth lightweight groove 19 makes it easier for the limiting pressure frame 17 to cooperate with the second limiting buckle 4 to produce deformation when squeezing into the second limiting buckle 4. After completion, the limiting block 25 on the rotating block 24 is rotated to insert the limiting block 25 into the third lightweight groove 15 set at the top of the second limiting buckle 4 and the fourth lightweight groove 19 opened on the limiting pressure frame 17, so as to quickly limit the limiting pressure frame 17 and the second limiting buckle 4. The coordinated use of the structures further makes the use effect of the locking mechanism better, and the structure is simple, and it is convenient and quick to use.

[0032] The working principle of the technical solution provided by the present invention is as follows: When in use, the user holds the first curved portion 12 with his hand to open the fixing frame 1, and then installs the fixing frame 1 on the patient's hand, and then loosens the first curved portion 12 to make the fixing frame 1 rebound and stably clamp and fix it on the patient's hand. When installing and using the fixing frame 1, the slot 9 is located at the patient's intravenous infusion site, and the outer walls of the fixing frame 1 and the first curved portion 12 are wrapped with a layer of cotton cloth, so that when the fixing frame 1 and the first curved portion 12 are in contact with the arm, the patient feels more comfortable. The setting of the first lightweight groove 8 can enhance the deformation ability of the fixing frame 1, save the production cost of the fixing frame 1, and enhance the air permeability and comfort of the fixing frame 1. In addition, with the opening of the first weakened portion 11 and the second lightweight groove 13, the fixing frame 1 is more easily deformed by external force and opened when installed on the patient's hand, so that the fixing frame 1 can be quickly installed on the patient's hand. After the fixing frame 1 is installed, the infusion needle is inserted into the first limiting buckle 3. The guidance of the first limiting buckle 3 can assist the medical staff to quickly insert the needle at a more appropriate angle, thereby reducing the error of the angle and the problem of inaccurate needle insertion due to hand shaking. In addition, the first connecting frame 5, the second connecting frame 6 and the second supporting frame 7 are used in coordination to assist the first supporting frame 2, so that the first limiting buckle 3 on the first supporting frame 2 has better stability when assisting the needle insertion. Then, the position of the second connecting frame 6 on the second supporting frame 7 is adjusted. The first support frame 2 is straightened so that the first support frame 2 and the first limit buckle 3 are close to the outer wall of the fixing frame 1, so that the infusion needle can be quickly and stably fixed on the back of the patient's hand after the puncture is completed, and the fourth weakened portion 31 is used to make it easier for the first support frame 2 to deform from the fourth weakened portion 31 under the action of external force, so that the first support frame 2 can be quickly deformed to a straight line when folded, and the seventh lightweight groove 28 is further opened to increase the deformation capacity of the first support frame 2, and make the cost of the first support frame 2 lower and the quality The amount is smaller, and the second guide part 30 designed on the top of the first limit buckle 3 can be used to guide the second guide part 30 to facilitate the insertion of the infusion needle from the top, and the setting of the third guide part 32 makes it easier for the side of the first support frame 2 that is not fixedly connected to the fixing frame 1 to follow the guidance of the third guide part 32 and approach the top outer wall of the fixing frame 1, and the cross-section of the first connecting frame 5 and the second connecting frame 6 forms a triangle, so that the structural stability of the first connecting frame 5 and the second connecting frame 6 is better, so that when adjusting the first support frame 2, the first support frame 2 is not easy to be skewed and shaken, which effectively enhances the stability of the first support frame 2 in two use states, and by opening the sixth lightweight groove 27 on the second support frame 7, the mass of the second support frame 7 can be reduced, and the cost of the second support frame 7 can be reduced, and at the same time, the second support frame 7 is more likely to deform when subjected to force, and the second support frame 7 is further more likely to deform from the third weakened part 26 by using the third weakened part 26, and the warm baby patch is inserted and installed between the gap formed by the second support frame 7 and the fixing frame 1,The hot baby patch can be quickly installed on the top of the fixing frame 1 for use. The hot baby patch can be used in conjunction with the device to heat the liquid in the infusion tube and keep the back of the patient's hand warm, making the patient more comfortable during infusion. The setting of the fixing frame 1 prevents the hot baby patch from directly contacting the patient's skin, and effectively prevents the hot baby patch from overheating and causing discomfort to the patient. The second curved portions 29 arranged on both sides of the second connecting frame 6 are for the purpose of facilitating the second connecting frame 6 to quickly hook the second supporting frame 7, and the sixth lightweight groove 27 opened on the second supporting frame 7 can also be used to limit the position of the second connecting frame 6 and make the second connecting frame 6 further and more stably installed on the top of the second supporting frame 7. The position of the second connecting frame 6 enhances the curvature of the second supporting frame 7 and can further press the baby warmer against the top of the fixing frame 1, thereby increasing the stability of the installation of the baby warmer. Then, by utilizing the setting of the second limiting buckle 4, after the infusion needle is fixed, the infusion tube is slightly bent and the other side of the infusion tube is quickly fixed on the second limiting buckle 4, thereby enhancing the stability of the infusion tube and the infusion needle. In addition, by utilizing the setting of the limiting pressure frame 17, the infusion tube can be further limited, so that the infusion tube can be more stably placed in the second limiting buckle 4. The installation of the rotating block 24 and the limiting block 25 is used for the subsequent limiting of the second limiting buckle 4 and the limiting pressure frame 17, so as to facilitate the subsequent rapid locking of the infusion tube in the second limiting buckle 4 after the infusion is completed. Through the shape design of the second limiting buckle 4, the second limiting buckle 4 can be better adapted to the shape of the infusion tube, so that the infusion tube can be more stably arranged in the second limiting buckle 4 when in use, and the setting of the first guide portion 16 can further enable the infusion tube to be more quickly installed in the second limiting buckle 4 by utilizing the guidance of the first guide portion 16, and the opening of the third lightweight groove 15 makes it easier for the second limiting buckle 4 to deform under the action of external force, the shape design of the elastic sheet 20 makes it easier for the elastic sheet 20 to deform along its bending portion, and the second weakened portion 22 opened thereon makes it easier for the elastic sheet 20 to deform from the second weakened portion 22 when subjected to force, and the opening of the fifth lightweight groove 21 enhances the deformation ability of the elastic sheet 20 The second buffer cavity 23 opened on the fixing frame 1 allows the inner wall of the fixing frame 1 to better squeeze the second limiting buckle 4, so that when the second limiting buckle 4 is folded in the limiting groove 14, it can be better folded and squeezed inward, and the limiting pressing frame 17 is pressed into the second limiting buckle 4, so that the limiting pressing frame 17 further squeezes the infusion tube in the second limiting buckle 4, so that the infusion tube in the second limiting buckle 4 is quickly locked, and the first buffer cavity 18 is opened to make the limiting pressing frame 17 have a better squeezing effect on the infusion tube in the second limiting buckle 4, and the fourth lightweight groove 19 is opened to make the limiting pressing frame 17 easier to cooperate with the second limiting buckle 4 to produce deformation when squeezing into the second limiting buckle 4. After completion, the limiting block 25 on the rotating block 24 is rotated,The limiting block 25 is inserted into the third lightweight groove 15 set on the top of the second limiting buckle 4 and the fourth lightweight groove 19 opened on the limiting pressure frame 17, and the limiting pressure frame 17 and the second limiting buckle 4 are quickly limited. When the alarm body 10 detects whether the injection of the drip infusion is completed, an alarm sound is issued to remind the patient. At this time, the patient can quickly press the locking mechanism to lock the infusion tube, and then wait for the medical staff to come to change the medicine or remove the needle. When the medical staff comes, the limiting block 25 is rotated to release the limiting of the second limiting buckle 4 and the limiting pressure frame 17, and the infusion tube in the second limiting buckle 4 can be circulated again, and the position of the second connecting frame 6 is adjusted again to make the second connecting frame 6 in the first state. Under the situation, the limit of the infusion needle can be quickly released and the infusion needle can be pulled out. The added coordinated use of the structure effectively prevents the problem of blood reflux or air ingress during the waiting period for the medical staff to come, and the limit guide mechanism can well assist the medical staff in infusion and acupuncture, thereby facilitating the acupuncture operation. In addition, by using the coordinated use of the structures, the infusion needle and the infusion tube can be quickly fixed on the back of the patient's hand, thereby avoiding the problem of the existing adhesive tape sticking method easily falling off, causing the needle and the tube to loosen and fall off, or the problem of pulling the patient's skin when tearing off the tape, causing the patient to have severe discomfort. The structure of the device is simple and easy to use and operate.
