Description

Technical Field

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

[0002] In modern medical processes, the use of drip infusion drug injection is quite extensive and common. However, at the end of drip injection, the hydraulic pressure in the injection tube will suddenly decrease due to the gradual exhaustion of the drip liquid, and then the blood will flow back reversely through the injection needle due to insufficient hydraulic pressure. Moreover, when the drip liquid is completely exhausted, the air in the injection tube may flow into the patient's blood vessel, causing troubles and inconveniences in medical care and even endangering the patient's safety. Therefore, during the process of drip infusion injection, it is often necessary to visually monitor manually to detect whether the drip liquid infusion is finished, so as to avoid the occurrence of the above situations.

[0003] However, the manual monitoring method consumes manpower. And in the case of no family member accompanying, the patient infuses alone and may fall asleep due to drowsiness, thus unable to observe in time whether the drip infusion is finished. Therefore, an alarm device for real-time monitoring of whether the drip infusion is finished has emerged. However, this device can only issue an alarm and cannot block the liquid or air in the infusion tube in time. And in some peak periods, medical staff cannot help the patient replace the infusion bottle in time, resulting in the risk of blood backflow still existing. And the existing structure for blocking the infusion tube is set at a relatively high position, which is not convenient for the patient to operate by himself / herself to block the infusion tube when used by a patient with inconvenient movement after surgery. Therefore, the present application provides a drip warning device to meet the needs. Summary of the Invention

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting the combined use of the limit guiding mechanism and the locking mechanism, when the alarm device body detects whether the drip infusion is finished, an alarm sound is emitted to remind the patient. At this time, the patient can quickly press the operation locking mechanism to lock the infusion tube, and then wait for the medical staff to come for dressing change or needle removal, effectively preventing the problems of blood backflow or air entry during the period of waiting for the medical staff. And the limit guiding mechanism can well assist the medical staff in infusing and puncturing, thus facilitating the puncturing operation. Moreover, by using the cooperation between the structures, the infusion needle and the infusion tube can be quickly fixed on the back of the patient's hand, thereby avoiding the problems that the existing adhesive tape sticking method is easy to fall off, resulting in the loosening and falling off of the needle and the needle tube, or the problem that the patient has a serious discomfort when the tape is torn off, and the structure is simple, which is convenient for the use of patients and medical staff;

[0018] By arranging a first support frame and a first limit buckle in the limit guide mechanism, the cross section of the first limit buckle is C-shaped, the first support frame and the first limit buckle are integrally formed, and the opening of the first limit buckle is upward, and by inserting the infusion needle into the first limit buckle, the guidance of the first limit buckle can assist 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. The design of the structure effectively increases the convenience of the infusion operation, and by utilizing the opening of the fourth weakened portion, the first support frame is more likely to generate a shape from the fourth weakened portion under the action of an external force. The seventh lightweight slot further increases the deformation capacity of the first support frame, and makes the first support frame lower in cost and lighter in weight. The second guide portion designed at the top of the first limit buckle can facilitate the insertion of the infusion needle from the top by the guidance of the second guide portion, and the third guide portion is provided to make it easier for the side of the first support frame that is not fixedly connected to the fixing frame to follow the guidance of the third guide portion and closely approach the top outer wall of the fixing frame. The structure is simple, and the use of the structure further makes the use effect of the limit guide mechanism better.

[0019] By arranging the first connecting frame, the second connecting frame and the second supporting frame in the limiting guide mechanism, not only can the first connecting frame, the second connecting frame and the second supporting frame be used in cooperation to play an auxiliary supporting role for the first supporting frame, so that the first limiting buckle on the first supporting frame has better stability when assisting acupuncture, and adjusting the position of the second connecting frame on the second supporting frame can also straighten the first supporting frame, so that the first supporting frame and the first limiting buckle are tightly attached to the outer wall of the fixing frame, 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 cross-sections of the first connecting frame and the second connecting frame form a triangle, which makes the structural stability of the first connecting frame and the second connecting frame better, so that when the first supporting frame is adjusted, the first supporting frame is not easy to be skewed and shaken, which effectively enhances the first supporting frame in the two The second support frame has a sixth lightweight groove, which can reduce the weight of the second support frame and the cost of the second support frame. At the same time, the second support frame is more likely to deform when subjected to force, and the third weakened portion is used to make it easier for the second support frame to deform from the third weakened portion. The two second support frames are set to different lengths to facilitate the insertion of the warm baby patch from the second support frame on the longer side into the gap formed by the second support frame and the fixed frame, so that the warm baby patch can be quickly installed on the top of the fixed frame for use, so that the use of the warm baby patch in conjunction with the device can heat the liquid in the infusion tube while keeping the back of the patient's hand warm, so that the patient is more comfortable during infusion, and the coordinated use of the structures further makes the use effect of the limiting guide mechanism better;

[0020] By providing a second limiting buckle and a limiting pressure frame in the locking mechanism, not only can the second limiting buckle be used to fix the infusion needle, but also the other side of the infusion tube can be quickly fixed to the second limiting buckle after the infusion tube is slightly bent, thereby enhancing the stability of the infusion tube and the infusion needle. In addition, the limiting pressure frame can be used to further limit the infusion tube, so that the infusion tube is more stably placed in the second limiting buckle, and the limiting pressure frame can be pressed into the second limiting buckle to further squeeze the infusion tube in the second limiting buckle, so that the infusion tube in the second limiting buckle is quickly locked. The opening of the buffer cavity enables the limiting pressure frame to have a better squeezing effect on the infusion tube in the second limiting buckle, and the opening of the fourth lightweight groove makes it easier for the limiting pressure frame to cooperate with the second limiting buckle to produce deformation when squeezing into the second limiting buckle. After completion, the second limiting buckle is pressed into the limiting groove, and then the limiting block on the rotating block is rotated, so that the limiting block is inserted into the third lightweight groove set at the top of the second limiting buckle to quickly limit the second limiting buckle, and the limiting groove is used to limit and squeeze the second limiting buckle, so that the infusion tube is further installed in the second limiting buckle for use more stably, and the coordinated use of the structures further makes the use effect of the locking mechanism better;

[0021] By arranging an elastic sheet in the locking mechanism, not only can the shape design of the elastic sheet make it easier for the elastic sheet to deform along its bending portion, so that the second limit buckle is located at the top of the limit groove in the first use state, which is convenient for installing the infusion tube in the second limit buckle, and the second weakened portion provided thereon makes it easier for the elastic sheet to deform from the second weakened portion when subjected to force, the provision of the fifth lightweight groove enhances the deformation capacity of the elastic sheet, and the coordinated use of the elastic sheet and the limit groove makes the locking mechanism have a better squeezing effect when locking the infusion tube in the second limit buckle, further effectively preventing the problem of blood reflux or air entry after the infusion is completed, and the structure is simple, and the coordinated use of the structures further makes the use effect of the locking mechanism better;

[0022] By arranging a rotating block and a limiting block in the locking mechanism, the rotating block and the limiting block are used to limit the second limiting buckle and the limiting pressing frame, so that during infusion, the second limiting buckle and the infusion tube therein are fixed in the limiting groove, so that the infusion tube will not be positionally shifted during the infusion process, and when the infusion is completed, the limiting pressing frame is pressed to the infusion tube in the second limiting buckle to flatten it for locking, and then the rotating block and the limiting block can be used to stably limit the second limiting buckle and the limiting pressing frame in the limiting groove at the same time, and the coordinated use of the structures further makes the use effect of the locking mechanism better;

[0023] Through the coordinated use of the limit guiding mechanism, the locking mechanism and each component therein, this device can not only achieve good effects of alarming and locking the infusion tube, but also facilitate the operation of medical staff for patient infusion, thereby increasing the practicability of the device. Moreover, the use of the device effectively saves manpower, improves the work efficiency of medical staff.

[0041] As Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention provides a drip warning device, which includes a fixing frame 1. One side of the top of the fixing frame 1 is fixedly connected to a first support frame 2. An infusion tube is installed on the top of the fixing frame 1, and an infusion needle is installed at the end of the infusion tube. An alarm body 10 is installed on the infusion tube; a limit guiding mechanism, which is used for fixing and puncture guiding of the infusion needle, and the limit guiding mechanism is connected to the first support frame 2; a locking mechanism, which is used for locking the inside of the infusion tube, and the locking mechanism is connected to the fixing frame 1. This device has two usage states. In the first usage state, the first support frame 2, the first connecting frame 5, the second connecting frame 6 and the second support frame 7 are all in a natural bending state. In the first state, the two end parts of the second connecting frame 6 are installed in the middle of the second support frame 7. In the second usage state, the end of the infusion tube is fixed on the top of the second limit buckle 4, and the two sides of the second connecting frame 6 are installed on the side close to the alarm body 10. Under the influence of the tensile force generated by the interaction between the second connecting frame 6, the first connecting frame 5 and the first support frame 2, they tend to be straight lines, and under the influence of the tensile force generated by the interaction between the structures, the bending degree of the second support frame 7 increases, and the two second support frames 7 show a bending trend towards the center position of the fixing frame 1. At this time, the fixing frame 1 generates an inward tightening trend. One side bottom of the first support frame 2 close to the edge of the fixing frame 1 is fixedly connected to the outer wall of the top of the fixing frame 1, and one side of the first support frame 2 close to the center position of the fixing frame 1 abuts against the fixing frame 1. The installation method and working principle of the above-mentioned alarm body 10 are existing mature technologies, so no more details will be described here. By using the cooperation of the limit guiding mechanism and the locking mechanism, the alarm body 10 can detect whether the drip infusion is finished and emit an alarm sound to remind the patient. At this time, the patient can quickly press the operation locking mechanism to lock the infusion tube, and then wait for the medical staff to come for dressing change or needle removal, effectively preventing the problems of blood backflow or air entry during the period of waiting for the medical staff. And the limit guiding mechanism can well assist the medical staff in infusing and puncturing the needle, thus facilitating the puncture operation. And by using the cooperation between the structures, the infusion needle and the infusion tube can be quickly fixed on the back of the patient's hand, thus avoiding the problems that the existing adhesive tape pasting method is easy to fall off, resulting in the loosening and falling off of the needle and the needle tube, or the problem that the patient has a serious discomfort when tearing off the tape. Moreover, the structure of the device is simple, easy to use quickly, and the production cost of the device is low, which is convenient for production and use.

[0042] Furthermore, first lightweight grooves 8 are equidistantly formed at the top of the fixing frame 1, a slot 9 is formed at the center of the top of the first support frame 2, first weakening parts 11 are formed on both sides of the fixing frame 1, first bending parts 12 are fixedly connected to both sides of the bottom of the fixing frame 1, and second lightweight grooves 13 are equidistantly formed on the first bending parts 12. The shape of the fixing frame 1 is adapted to the shapes of the palm and the back of the patient's hand. The area of the slot 9 is larger than that of the first lightweight groove 8. When the fixing frame 1 is installed and used, the slot 9 is located at the intravenous infusion site of the patient. Both the fixing frame 1 and the first bending parts 12 are arc-shaped structures, and both the fixing frame 1 and the first bending parts 12 are made of plastic materials. Moreover, the cross-section of the fixing frame 1 approaches a C shape. The fixing frame 1 and the first bending parts 12 are integrally formed. A layer of cotton cloth is wrapped around the outer walls of the fixing frame 1 and the first bending parts 12. Through the arrangement of the first lightweight grooves 8, the deformation ability of the fixing frame 1 can be enhanced, the production cost of the fixing frame 1 can be saved, and the air permeability and comfort of the fixing frame 1 can be enhanced. And in cooperation with the formation of the first weakening parts 11 and the second lightweight grooves 13, the fixing frame 1 is more likely to be deformed by external forces and opened when installed on the patient's hand, so that the fixing frame 1 can be quickly installed on the patient's hand, facilitating the subsequent stable fixing of the infusion needle and the infusion tube on the top of the fixing frame 1 for use. The structure is simple, and the combined use of the structures further improves the practicability of the device.

[0043] As Figures 1 to 8 shown, the limiting and guiding mechanism includes a first limiting buckle 3 installed on the first support frame 2. A first connecting frame 5 is fixedly connected to one side of the first limiting buckle 3 close to the center of the first support frame 2. A second connecting frame 6 is fixedly connected to the side of the first connecting frame 5 away from the first support frame 2. Second support frames 7 are installed at the bottoms of both ends of the second connecting frame 6. The cross-section of the first limiting buckle 3 is C-shaped. The first support frame 2 and the first limiting buckle 3 are integrally formed. The opening of the first limiting buckle 3 faces upward. Both ends of the second support frames 7 are fixedly connected to the outer wall of the top of the fixing frame 1. By inserting the infusion needle into the first limiting buckle 3, the guiding of the first limiting buckle 3 can assist medical staff to quickly insert the needle at a more appropriate angle, reducing the angle error and the problem of inaccurate needle insertion due to hand shaking. The design of the structure effectively improves the convenience of the infusion operation. And by using the cooperation of the first connecting frame 5, the second connecting frame 6 and the second support frames 7, an auxiliary supporting effect is exerted on the first support frame 2, making the first limiting buckle 3 on the first support frame 2 more stable when assisting in needle insertion. And adjusting the position of the second connecting frame 6 on the second support frames 7 can also straighten the first support frame 2, making the first support frame 2 and the first limiting buckle 3 closely adhere 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 puncture. Moreover, the structure is simple, convenient and fast to adjust, and the production cost of the structure is low, facilitating use.

[0044] Further, the first support frame 2, the first connecting frame 5 and the second connecting frame 6 are integrally formed. The first support frame 2 is made of plastic. The top of the first support frame 2 forms an acute angle in its natural state. A fourth weakening portion 31 is provided at the angled portion of the first support frame 2. Seventh lightweight grooves 28 are equidistantly provided on the first support frame 2. Second guiding portions 30 are provided on both sides of the top of the first limiting buckle 3. A third guiding portion 32 is provided on one side of the bottom of the first support frame 2 near the center of the fixing frame 1. The cross-sections of the first connecting frame 5 and the second connecting frame 6 form a triangle. The first connecting frame 5 and the second connecting frame 6 are arc-shaped structures with convex tops. The integrally formed structure has better stability. The cost of the plastic material is lower and it has good deformation ability. By using the fourth weakening portion 31, the first support frame 2 is more likely to deform from the fourth weakening portion 31 under the action of an external force, so that the first support frame 2 can quickly deform towards a straight line when it is folded. Moreover, the seventh lightweight grooves 28 further increase the deformation ability of the first support frame 2, and reduce the cost and mass of the first support frame 2. The second guiding portions 30 designed on the top of the first limiting buckle 3 can facilitate the insertion of the infusion needle from the top by using the guiding of the second guiding portions 30. The third guiding portion 32 makes the side of the first support frame 2 not fixedly connected to the fixing frame 1 more likely to closely adhere to and approach the outer wall of the top of the fixing frame 1 along the guiding of the third guiding portion 32. The cross-sections of the first connecting frame 5 and the second connecting frame 6 form a triangle, making the structures of the first connecting frame 5 and the second connecting frame 6 more stable. Thus, when adjusting the first support frame 2, the first support frame 2 is not likely to be skewed or vibrated, effectively enhancing the stability of the first support frame 2 in two usage states. The combined use of the structures further improves the usage effect of the limiting and guiding mechanism, and has a simple structure and good practicability.

[0045] Such as Figures 1 to 8As shown, the second support frame 7 is equidistantly provided with sixth lightweight grooves 27, a third weakening part 26 is provided in the middle of the second support frame 7, the second support frame 7 is of an arc-shaped structure, the length of one second support frame 7 is greater than that of the other second support frame 7, both ends of the second connecting frame 6 are provided with second bending parts 29. By providing the sixth lightweight grooves 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. At the same time, when the second support frame 7 is stressed, it is more likely to deform. And by providing the third weakening part 26, the second support frame 7 is further more likely to deform from the third weakening part 26. The two second support frames 7 are set to different lengths to facilitate inserting the warming patch from the longer side of the second support frame 7 into the gap formed between the second support frame 7 and the fixing frame 1, so that the warming patch can be quickly installed on the top of the fixing frame 1 for use. The use of the warming patch in cooperation with the device can heat the liquid in the infusion tube and play a role in warming the back of the patient's hand at the same time, making the patient more comfortable during infusion. And by providing the fixing frame 1, the warming patch does not directly contact the patient's skin, effectively preventing the problem that the patient feels uncomfortable due to the overheating of the warming patch. The second bending parts 29 provided on both sides of the second connecting frame 6 are for facilitating the second connecting frame 6 to quickly hook the second support frame 7. And by using the sixth lightweight grooves 27 provided on the second support frame 7, the position of the second connecting frame 6 can also be limited, and the second connecting frame 6 can be further more stably installed on the top of the second support frame 7. And the structure is simple, and the cooperation between the structures further makes the use effect of the limit guiding mechanism better.

[0046] As Figures 1 to 8As shown, the locking mechanism includes a second limit buckle 4 installed on the top of the fixed frame 1. A limit groove 14 is provided at the top of the side of the fixed frame 1 away from the first support frame 2. An elastic piece 20 is fixedly connected to the inner wall of the limit groove 14. The top of the elastic piece 20 is fixedly connected to the bottom of the second limit buckle 4. A limit pressing frame 17 is fixedly connected to the top of one side of the second limit buckle 4. A rotating block 24 is installed at the top of the side of the fixed frame 1 away from the first support frame 2. A limit block 25 is installed on one side of the rotating block 24. The shape of the limit groove 14 is adapted to the shape of the second limit buckle 4. The inner diameter of the second limit buckle 4 is equal to the outer diameter of the infusion tube. Both the second limit buckle 4 and the elastic piece 20 are made of plastic material, and the second limit buckle 4 and the elastic piece 20 are of an integral structure. By using the setting of the second limit buckle 4, after the infusion needle is fixed, the infusion tube can be slightly bent, and then the other side of the infusion tube can be quickly fixed on the second limit buckle 4, thereby enhancing the stability of the infusion tube and the infusion needle. And by using the setting of the limit pressing frame 17, the infusion tube can be further limited, so that the infusion tube is more stably placed in the second limit buckle 4. The installation of the rotating block 24 and the limit block 25 is used to limit the second limit buckle 4 and the limit pressing frame 17 subsequently, which is convenient for quickly locking the infusion tube in the second limit buckle 4 after the infusion is completed. The specific use method of the above-mentioned rotating block 24 and limit block 25 will be described in detail below. The structure is simple, and the cooperation between the structures further makes the device more practical.

[0047] As Figures 1 to 8As shown, the cross section of the second limiting buckle 4 is C-shaped, the opening width of the second limiting buckle 4 is smaller than the diameter of the infusion tube, the top of the second limiting buckle 4 is provided with a first guide portion 16, the second limiting buckle 4 is provided with a third lightweight groove 15 equidistantly arranged in an annular manner, the cross section of the elastic sheet 20 is S-shaped, the elastic sheet 20 is provided with a fifth lightweight groove 21 equidistantly arranged, the elastic sheet 20 is provided with two second weakened portions 22, the top of the fixing frame 1 is provided with a second buffer cavity 23 equidistantly arranged in an annular manner near the second limiting buckle 4, the limiting pressure frame 17 is provided with a first buffer cavity 18 equidistantly arranged on one side of the center position of the second limiting buckle 4, and the limiting pressure frame 17 is away from A fourth lightweight groove 19 is equidistantly provided on one side of the center position of the second limit buckle 4. The shape design of the second limit buckle 4 allows the second limit buckle 4 to better match the shape of the infusion tube, so that the infusion tube can be more stably arranged in the second limit buckle 4 when in use. The setting of the first guide portion 16 further allows the infusion tube to be more quickly installed in the second limit buckle 4 by utilizing the guidance of the first guide portion 16. The opening of the third lightweight groove 15 allows the second limit buckle 4 to be more easily deformed under the action of external force. The shape design of the elastic sheet 20 allows the elastic sheet 20 to be more easily deformed along its curved portion. The second weakened portion 22 opened on the upper part makes it easier for the elastic sheet 20 to deform from the second weakened portion 22 when subjected to force. 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 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.

[0048] The working principle of the technical solution provided by the present invention is as follows:

[0049] When in use, the user holds the first bending part 12 with the hand to open the fixing frame 1, then installs the fixing frame 1 on the patient's hand, and then releases the first bending part 12 to make the fixing frame 1 rebound and stably clamp and fix on the patient's hand. When installing and using the fixing frame 1, the slot 9 is located at the intravenous infusion site of the patient. The outer walls of the fixing frame 1 and the first bending part 12 are both wrapped with a layer of cotton cloth, so that when the fixing frame 1 and the first bending part 12 contact the arm, the comfort of the patient is better. Through the setting of the first lightening slot 8, the deformation ability of the fixing frame 1 can be enhanced, and the production cost of the fixing frame 1 can be saved, and the air permeability and comfort of the fixing frame 1 can be enhanced. And with the opening of the first weakening part 11 and the second lightening slot 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 installing the fixing frame 1, insert the infusion needle into the first limiting buckle 3. The guidance of the first limiting buckle 3 can assist medical staff to quickly insert the needle at a more appropriate angle, reduce the angle error, and reduce the problem of inaccurate needle insertion due to hand shaking. And by using the cooperation of the first connecting frame 5, the second connecting frame 6 and the second support frame 7, it plays an auxiliary supporting role for the first support frame 2, so that the first limiting buckle 3 on the first support frame 2 has better stability when assisting in needle insertion. Then adjust the position of the second connecting frame 6 on the second support frame 7 to straighten the first support frame 2, so that the first support frame 2 is tightly attached to the outer wall of the fixing frame 1 with the first limiting buckle 3, so that the infusion needle is quickly and stably fixed on the back of the patient's hand after puncture. And by using the opening of the fourth weakening part 31, the first support frame 2 is more easily deformed from the fourth weakening part 31 under the action of external force, so that the first support frame 2 can quickly deform and tend to be straight when folded. And the opening of the seventh lightening slot 28 further increases the deformation ability of the first support frame 2, and makes the cost of the first support frame 2 lower and the quality smaller. And the second guiding part 30 designed at the top of the first limiting buckle 3 can facilitate the insertion of the infusion needle from the top by the guidance of the second guiding part 30. And the setting of the third guiding part 32 makes the side of the first support frame 2 not fixedly connected to the fixing frame 1 more easily close to the outer wall of the top of the fixing frame 1 along the guidance of the third guiding part 32. And the cross sections of the first connecting frame 5 and the second connecting frame 6 form 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, effectively enhancing the stability of the first support frame 2 in two use states. And by opening the sixth lightening slot 27 on the second support frame 7, the quality 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 easily deformed when stressed. And by using the opening of the third weakening part 26, the second support frame 7 is further more easily deformed from the third weakening part 26. Insert the warm baby sticker into the gap formed between 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,Insert the limit block 25 into the third lightweight slot 15 at the top of the second limit buckle 4 and the fourth lightweight slot 19 opened on the limit pressure frame 17 to quickly limit the limit pressure frame 17 and the second limit buckle 4. When the alarm device body 10 detects whether the drip infusion is finished, it emits an alarm sound to remind the patient. At this time, the patient can quickly press the operation locking mechanism to lock the infusion tube, and then wait for the medical staff to come for dressing change or needle removal. When the medical staff arrives, rotate the limit block 25 to release the limit of the second limit buckle 4 and the limit pressure frame 17, and the infusion tube in the second limit buckle 4 can flow again. Adjust the position of the second connecting frame 6 again to make the second connecting frame 6 in the first state, and the limit of the infusion needle can be quickly released and the infusion needle can be pulled out. The combined use of the structure effectively prevents the problems of blood backflow or air entry during the period of waiting for the medical staff, and the limit guiding mechanism can well assist the medical staff in infusing and puncturing, thus facilitating the puncture operation. Moreover, by using the cooperation between the structures, the infusion needle and the infusion tube can be quickly fixed on the patient's hand back, thus avoiding the problems that the existing adhesive tape sticking method is easy to fall off, resulting in the loosening and falling off of the needle and the needle tube, or the problem that pulling the patient's skin when tearing off the tape causes serious discomfort to the patient. The structure of the device is simple and convenient to use and operate.
