Description

Technical Field

[0001] The present invention belongs to the technical field of medical auxiliary machinery, in particular to a medical infusion alarm device. Background Art

[0002] As a common medical consumable, the infusion set is sterile-treated to establish a channel between the vein and the drug solution for intravenous infusion. It is generally composed of eight parts: an intravenous needle or injection needle, a needle cap, an infusion hose, a drug filter, a flow rate regulator, a drip pot, a bottle stopper puncture device, and an air filter.

[0003] The amount of injection required for infusion is large, and it usually takes a long time to be completely injected into the human body. It is difficult for medical staff to accompany the patient throughout the infusion process, and they can only conduct ward inspections at certain intervals. If they find that the infusion is completed during the inspection, they will remove the needle in time.

[0004] Because the infusion takes too long, under normal circumstances, medical staff can patrol and remove the needle on their own, or when the infusion is about to end, the patient presses the alarm to remind the medical staff. However, if the patient falls asleep during the infusion and the medical staff does not patrol, it will affect the timing of the dressing change, and the patient will not be able to spontaneously remind the nurses and doctors, affecting the patient's recovery.

[0005] To this end, the present invention provides a medical infusion alarm device. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a medical infusion alarm device described in the present invention comprises a support frame and a connecting frame; the support frame and the connecting frame are of integrated design; a hanging rope is installed above the connecting frame; a placement ring seat is installed on the surface of the support frame; a placement cavity is opened inside the placement ring seat, and the placement cavity can be designed as the type of infusion bottle in the prior art; an elastic frame is fixedly connected to the surface of the support frame; the number of the elastic frames is two, and they are symmetrically arranged; the side of the elastic frame away from the support frame is connected to the surface of the connecting frame; the surface of the elastic frame is fixedly connected to a connecting rod; one side of the connecting frame is slidably connected to a contact rod; the number of the contact rods is two, and they are symmetrically arranged; a contact point is provided on the surface of each contact rod;

[0008] When working, first hang the device in a suitable position by a hanging rope. When placing an infusion bottle inside the placement ring seat, pass the puncture device of the bottle stopper through the bottom of the bottle to hang water for the patient. After the bottle is placed, the gravity of the bottle, the liquid medicine and the placement ring seat is greater than the telescopic force of the elastic frame. The placement ring seat will pull the elastic frame to make the elastic frame in a telescopic state. At this time, the connecting rod and the contact rod are in a state of being apart, and the two contacts of the two contact rods are in a state of being apart from each other. As the liquid medicine inside the bottle gradually decreases and decreases to a preset value, the elastic frame will slowly recover from the telescopic state, and the elastic frame will drive the connecting rod on its side surface to move synchronously, so that the connecting rod moves to the side close to the contact rod. At this time, the bottom of the contact rods on both sides are subjected to the pressure of the connecting rods on both sides, and the contact rods on both sides will approach each other. Subsequently, the contacts on the surfaces of the contact rods on both sides will contact each other. At this time, the external alarm will start and make a sound, which can promptly remind the nurse to come and change the liquid.

[0009] Preferably, one side of the connecting frame is fixedly connected to a limiting frame; the contact rod is slidably connected to the inside of the limiting frame; the limiting frame is in the shape of a circular arc; when working, a limiting frame is provided on the outer surface of the contact rod, which can limit the position of the contact rod, so that the contact rods on both sides can slide along the inside of the limiting frame when under pressure, thereby facilitating the contact between the two contact rods and causing the alarm to sound.

[0010] Preferably, the outer surface of each contact rod is fixedly connected to a limit spring; the limit spring is connected to the limit frame on the side away from the contact rod; the shape of each contact rod at the position close to the connecting rod is arc-shaped; a limit spring is provided on the surface of the contact rod, which can facilitate the contact rod to recover when it is not under pressure, thereby facilitating the contact rods to move away from each other and allowing the loading to be used again, and the bottom is set to an arc shape, which can facilitate the connecting rod to press the contact rod to cause the contact rod to move.

[0011] Preferably, the upper surface of each elastic frame is fixedly connected to an inclined plate, as shown in the figure, the inclined plate is designed to be inclined toward the placement ring seat; the bottom of the connecting frame is fixedly connected to a limiting frame; the number of the limiting frames is two, and they are symmetrically arranged on the left and right; a push column is slidably connected between the two limiting frames; one end of the push column is close to the inclined surface of the inclined plate, and the other end is fixedly connected to a tightening ring; as shown in the figure, the number of the tightening rings is two, and the diameter of the tightening ring is larger than the diameter of the placement ring seat; during the movement of the inclined plate, the inclined surface will contact one end of the push column; at this time, the push columns and tightening rings on both sides are close to each other, and this tightening ring will clamp the infusion bottle to ensure the stability of the infusion bottle during the infusion process, and can prevent the infusion bottle from being skewed, and avoid the problem of unsafe infusion due to shaking of the line due to its shaking.

[0012] Preferably, the shape of the push post close to the inclined plate is inclined, and its inclination is adapted to the inclined surface of the inclined plate; when working, by placing infusion bottles of different sizes inside the placement ring seat, the weights of infusion bottles of different sizes are different, so that the inclined plate is compressed and moved by different distances, the inclined plate pushes the push post to move different distances, and the push post drives the tightening ring to move different distances, so that the tightening ring can clamp infusion bottles of different sizes, thereby improving the scope of application of this device and facilitating the operation of medical staff.

[0013] Preferably, a heating wire is fixedly connected to the inner wall of each tightening ring; a plurality of heating wires are provided, and are arranged at equal distances inside the tightening ring; the heating wire is connected to an external control power supply; during operation, when the tightening rings on both sides approach each other, the heating wires in the tightening rings will be wrapped around the surface of the infusion bottle at the same time. At this time, the medical staff turns on the external power supply to make the heating wire heat the liquid in the infusion bottle. For example, when performing infusion in a low temperature environment such as winter, it can prevent the injection liquid with too low temperature from entering the patient's body, causing the patient's body temperature to drop significantly, thereby improving the comfort during infusion, and at the same time preventing the patient's body temperature from dropping excessively, causing a cold.

[0014] Preferably, a limiting groove is provided on the surface of the push column; the number of the limiting grooves is two and they are symmetrically arranged; the surface of the limiting frame is fixedly connected to a columnar rod; the number of the columnar rods is two and they are respectively arranged inside the limiting grooves; the shape of the columnar rod is adapted to the shape of the limiting groove; during the movement of the push column, the position of the push column can be limited under the action of the limiting groove and the columnar rod, thereby avoiding the phenomenon of deflection of the push column during the movement.

[0015] Preferably, a telescopic rod is fixedly connected to the upper surface of the inclined plate; a telescopic spring is fixedly connected to the outer surface of the telescopic rod; the top ends of the telescopic rod and the telescopic spring are connected to the side surface of the connecting frame; when the inclined plate moves downward, the inclined plate will simultaneously pull the telescopic rod and the telescopic spring to move and deform, and when the liquid inside the infusion bottle gradually decreases, the force on the telescopic rod and the telescopic spring becomes smaller, and the telescopic rod and the telescopic spring recover, thereby facilitating the alarm to sound and remind medical staff to come and remove the needle or change the liquid.

[0016] Preferably, a telescopic elastic plate is fixedly connected to the bottom of the placing ring seat; a plurality of telescopic elastic plates are provided and are arranged in a circular array at the bottom of the placing ring seat; a receiving plate is below the placing ring seat and fixedly connected to the telescopic elastic plate; the receiving plate is cylindrical in shape; when placing an infusion bottle inside the placing ring seat, the bottom of the infusion bottle can be placed on the surface of the telescopic elastic plate and the receiving plate, and under the effect of a certain degree of elasticity of the telescopic elastic plate, the infusion bottle can be completely stuck inside the placing ring seat, which is conducive to limiting the position of the infusion bottle.

[0017] Preferably, the inner wall of each tightening ring is fixedly connected with a convex friction block; the shape of the convex friction block is uneven, and the material of the convex friction block is rubber; the convex friction block is arranged on the inner wall of the tightening ring, which can increase the clamping force of the tightening ring on the infusion bottle, which is beneficial to the fixed clamping of the infusion bottle.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The medical infusion alarm device described in the present invention is that as the liquid medicine inside the hanging bottle gradually decreases and decreases to a preset value, the elastic frame will slowly recover from the telescopic state, and the elastic frame will drive the connecting rod on its side surface to move synchronously, so that the connecting rod moves toward the side close to the contact rod. At this time, the bottom of the contact rods on both sides are subjected to the pressure of the connecting rods on both sides, and the contact rods on both sides will approach each other. Then the contacts on the surfaces of the contact rods on both sides will contact each other. At this time, the external alarm will start and make a sound, which can promptly remind the nurse to come and change the liquid.

[0020] 2. The medical infusion alarm device described in the present invention is that when the elastic frame is subjected to the pressure of the hanging bottle and the medicine, the elastic frame will simultaneously drive the inclined plate on its upper surface to move. During the movement, the inclined plate will contact one end of the push column, and the inclined plate will press against one end of the push column, so that the push column drives the tightening ring to move. At this time, the push columns and the tightening ring on both sides are close to each other, and the tightening ring will clamp the infusion bottle to ensure the stability of the infusion bottle during the infusion process, and can prevent the infusion bottle from being in a skewed state, avoiding the problem of unsafe infusion caused by shaking of the line due to its shaking.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] Example 1

[0032] like Figures 1 to 6 As shown, a medical infusion alarm device described in an embodiment of the present invention includes a support frame 1 and a connecting frame 2; the support frame 1 and the connecting frame 2 are of integrated design; a hanging rope 201 is installed above the connecting frame 2; a placement ring seat 101 is installed on the surface of the support frame 1; a placement cavity is opened inside the placement ring seat 101, and the placement cavity can be designed as the type of infusion bottle in the prior art; an elastic frame 3 is fixedly connected to the surface of the support frame 1; the number of the elastic frames 3 is two, and they are symmetrically arranged; the side of the elastic frame 3 away from the support frame 1 is connected to the surface of the connecting frame 2; the surface of the elastic frame 3 is fixedly connected to a connecting rod 4; one side of the connecting frame 2 is slidably connected to a contact rod 5; the number of the contact rods 5 is two, and they are symmetrically arranged; the surface of each of the contact rods 5 is provided with a contact;

[0033] It should be noted that, in an embodiment of the present invention, when the two contacts are in contact, the other contact is connected to an alarm, which is a buzzer connected to a battery via a wire; when the two contacts are in contact with each other, the alarm is controlled to start, prompting the patient and medical staff to remove the needle in time.

[0034] In the prior art, since the time required for infusion is too long, under normal circumstances, medical staff can patrol and remove the needle on their own or when the infusion is about to be completed, the patient presses the alarm to remind the medical staff. However, if the patient falls asleep during the infusion process and the medical staff does not patrol, it will affect the timing of changing the dressing and cannot spontaneously remind the nurses and doctors, affecting the patient's recovery. When the device of the embodiment of the present invention is used, the device is first hung in a suitable position by the hanging rope 201. When the infusion bottle is placed inside the placement ring seat 101, the puncture device of the bottle stopper is passed through the bottom of the bottle to hang water for the patient. After the bottle is placed, the weight of the bottle, the liquid medicine and the placement ring seat 101 is greater than the telescopic force of the elastic frame 3. The placement ring seat 101 will pull the elastic frame 3, making the elastic frame 3 in a telescopic state. At this time, the connecting rod 4 When the medicine in the bottle is gradually reduced and reduced to a preset value, the elastic frame 3 will slowly recover from the telescopic state, and the elastic frame 3 will drive the connecting rod 4 on its side surface to move synchronously, so that the connecting rod 4 moves toward the side close to the contact rod 5. At this time, the bottoms of the contact rods 5 on both sides are under the pressure of the connecting rods 4 on both sides, and the contact rods 5 on both sides will approach each other. Then the contacts on the surfaces of the contact rods 5 on both sides will contact each other. At this time, the external alarm will start and make a sound, which can remind the nurse to come and change the liquid in time. The device can automatically alarm according to the content of the liquid in the bottle, so that the nurses on the ward rounds can quickly and accurately go to the patient to remove the needle in advance, avoiding the problem that the patient cannot remind the nurse to change the liquid because he is asleep.

[0035] One side of the connecting frame 2 is fixedly connected to the limiting frame 6; the contact rod 5 is slidably connected to the inside of the limiting frame 6; the limiting frame 6 is in the shape of an arc;

[0036] During operation, a limit frame 6 is provided on the outer surface of the contact rod 5, which can limit the position of the contact rod 5 so that the contact rods 5 on both sides can slide along the inside of the limit frame 6 when under pressure, thereby facilitating the contact between the two contact rods 5 and causing the alarm to sound.

[0037] The outer surface of each contact rod 5 is fixedly connected to a limit spring 51; the limit spring 51 is connected to the limit frame 6 on the side away from the contact rod 5; the shape of each contact rod 5 at the side close to the connecting rod 4 is an arc; a limit spring 51 is set on the surface of the contact rod 5, which can facilitate the contact rod 5 to recover when it is not under pressure, thereby facilitating the contact rods 5 to move away from each other and make this loading available again, and the bottom is set to an arc shape, which can facilitate the connection rod 4 to press the contact rod 5, so that the contact rod 5 moves.

[0038] The upper surface of each elastic frame 3 is fixedly connected to an inclined plate 7. Figure 2and Figure 3 As shown, the inclined plate 7 is designed to be inclined toward the placement ring seat 101; the bottom of the connecting frame 2 is fixedly connected to the limiting frame 8; the number of the limiting frames 8 is two, and they are arranged symmetrically on the left and right; a push column 9 is slidably connected between the two limiting frames 8; one end of the push column 9 is close to the inclined surface of the inclined plate 7, and the other end is fixedly connected to the tightening ring 10; Figure 1 As shown, there are two tightening rings 10, and the diameter of the tightening ring 10 is larger than the diameter of the ring seat 101; the inclined surface of the inclined plate 7 will contact one end of the push column 9 during the movement;

[0039] During operation, when the elastic frame 3 is subjected to the pressure of the hanging bottle and the medicine, the elastic frame 3 will simultaneously drive the inclined plate 7 on its upper surface to move. The inclined plate 7 will contact one end of the push column 9 during the movement, and the inclined plate 7 will press one end of the push column 9, so that the push column 9 drives the tightening ring 10 to move. At this time, the push columns 9 and the tightening ring 10 on both sides are close to each other. The tightening ring 10 will clamp the infusion bottle to ensure the stability of the infusion bottle during the infusion process, and can prevent the infusion bottle from being skewed, avoiding the problem of unsafe infusion caused by shaking of the line due to its shaking.

[0040] The shape of the push column 9 close to the inclined plate 7 is inclined, and its inclination is adapted to the inclined surface of the inclined plate 7; when working, by placing infusion bottles of different sizes inside the placement ring seat 101, the weights of infusion bottles of different sizes are different, so that the inclined plate 7 is compressed and moved by different distances, the inclined plate 7 pushes the push column 9 to move different distances, and the push column 9 drives the tightening ring 10 to move different distances, and then this tightening ring 10 can clamp infusion bottles of different sizes, thereby improving the applicability of this device and facilitating the operation of medical staff.

[0041] The inner wall of each tightening ring 10 is fixedly connected to a heating wire 11; a plurality of heating wires 11 are provided, and are equidistantly arranged inside the tightening ring 10; the heating wires 11 are connected to an external control power supply; during operation, when the tightening rings 10 on both sides are close to each other, the heating wires 11 that are prevented by the tightening rings 10 will simultaneously wrap around the surface of the infusion bottle. At this time, the medical staff turns on the external power supply to make the heating wires 11 heat the liquid in the infusion bottle. For example, when performing infusion in a low temperature environment such as winter, it can prevent the injection liquid with too low a temperature from entering the patient's body, causing the patient's body temperature to drop significantly, thereby improving the comfort level during infusion and preventing the patient's body temperature from dropping too much, causing a cold.

[0042] It should be noted that, in the embodiment of the present invention, the heating temperature of the infusion bottle by the heating wire 11 is set at a temperature acceptable to the human body, which can facilitate the infusion of the patient.

[0043] The surface of the push column 9 is provided with a limiting groove 12; the number of the limiting grooves 12 is two, and they are symmetrically arranged; the surface of the limiting frame 8 is fixedly connected to the column rod 13; the number of the column rod 13 is two, and they are respectively arranged inside the limiting groove 12; the shape of the column rod 13 is adapted to the shape of the limiting groove 12; when working, the column rod 13 is provided on the surface of the limiting frame 8, and the limiting groove 12 is provided on the surface of the push column 9, so during the movement of the push column 9, under the action of the limiting groove 12 and the column rod 13, the position of the push column 9 can be limited, thereby avoiding the phenomenon of deflection of the push column 9 during the movement.

[0044] The upper surface of the inclined plate 7 is fixedly connected to a telescopic rod 14; the outer surface of the telescopic rod 14 is fixedly connected to a telescopic spring 15; the top ends of the telescopic rod 14 and the telescopic spring 15 are connected to the side surface of the connecting frame 2; when the inclined plate 7 moves downward, the inclined plate 7 will simultaneously pull the telescopic rod 14 and the telescopic spring 15 to move and deform, and when the liquid inside the infusion bottle gradually decreases, the force on the telescopic rod 14 and the telescopic spring 15 becomes smaller, and the telescopic rod 14 and the telescopic spring 15 recover, thereby facilitating the alarm to sound and remind medical staff to come and remove the needle or change the liquid.

[0045] The bottom of the placing ring seat 101 is fixedly connected with a telescopic elastic plate 202; the telescopic elastic plates 202 are provided in plurality and are arranged in a circular array at the bottom of the placing ring seat 101; a receiving plate 203 is below the placing ring seat 101 and fixedly connected to the telescopic elastic plate 202; the receiving plate 203 is cylindrical in shape; when placing an infusion bottle inside the placing ring seat 101, the bottom of the infusion bottle can be placed on the surface of the telescopic elastic plate 202 and the receiving plate 203. Under the effect of a certain degree of elasticity of the telescopic elastic plate 202, the infusion bottle can be completely stuck inside the placing ring seat 101, which is conducive to limiting the position of the infusion bottle.

[0046] Example 2

[0047] like Figure 7 As shown, compared with Example 1, another embodiment of the present invention is: the inner wall of each tightening ring 10 is fixedly connected with a convex friction block 16; the shape of the convex friction block 16 is uneven, and the material of the convex friction block 16 is rubber; the convex friction block 16 is provided on the inner wall of the tightening ring 10, which can increase the clamping force of the tightening ring 10 on the infusion bottle, which is beneficial to the fixed clamping of the infusion bottle.

[0048] When working, first hang this device in a suitable position by hanging rope 201, when placing infusion hanging bottle inside the placing ring seat 101, pass the puncture device of bottle stopper through the bottom of hanging bottle to hang water for patient, after hanging bottle is placed, the self gravity of hanging bottle, liquid medicine and placing ring seat 101 is greater than the telescopic force of elastic frame 3, placing ring seat 101 will pull elastic frame 3, making elastic frame 3 in telescopic state, at this time connecting rod 4 and contact rod 5 are in telescopic state, and the two contacts of two contact rods 5 are in telescopic state. As the liquid medicine inside hanging bottle gradually decreases and decreases to a preset value, elastic frame 3 will slowly recover from telescopic state, and elastic frame 3 will drive the connecting rod 4 on its side surface to move synchronously, making connecting rod 4 move toward the side close to contact rod 5, at this time, the bottom of contact rod 5 on both sides is subjected to the pressure of connecting rod 4 on both sides, contact rod 5 on both sides will approach each other, then the contacts on the surface of contact rod 5 on both sides will contact each other, at this time external alarm will start, make sound, can promptly remind nurse to come and change liquid;

[0049] A limit frame 6 is provided on the outer surface of the contact rod 5 to limit the position of the contact rod 5 so that the contact rods 5 on both sides can slide along the inside of the limit frame 6 when under pressure, thereby facilitating the contact between the two contact rods 5 and causing the alarm to sound.

[0050] When the bottle is in a tilted position, the bottle is prevented from being tilted and the bottle is not in a tilted position, so that the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, so that the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, so that the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is prevented from being tilted and the bottle is not in a tilted position, and the bottle is

[0051] When the tightening rings 10 on both sides are close to each other, the heating wire 11 prevented by the tightening rings 10 will be wrapped around the surface of the infusion bottle at the same time. At this time, the medical staff turns on the external power supply to make the heating wire 11 heat the liquid in the infusion bottle. For example, when performing infusion in a low temperature environment such as winter, it can prevent the injection liquid with too low temperature from entering the patient's body, causing the patient's body temperature to drop significantly, improving the comfort during infusion, and at the same time preventing the patient's body temperature from dropping too much and causing a cold; a columnar rod 13 is provided on the surface of the limiting frame 8, and a limiting groove 12 is provided on the surface of the push column 9, so that during the movement of the push column 9, the position of the push column 9 can be limited by the action of the limiting groove 12 and the columnar rod 13, avoiding the push column 9 from being deflected during the movement;

[0052] When the inclined plate 7 moves downward, the inclined plate 7 will simultaneously pull the telescopic rod 14 and the telescopic spring 15 to move and deform. When the liquid medicine inside the infusion bottle gradually decreases, the force on the telescopic rod 14 and the telescopic spring 15 becomes smaller, and the telescopic rod 14 and the telescopic spring 15 are restored, thereby facilitating the alarm to sound and remind medical staff to come and remove the needle or change the liquid; when the infusion bottle is placed inside the placement ring seat 101, the bottom of the infusion bottle can be placed on the surface of the telescopic elastic plate 202 and the receiving plate 203. Under the effect of the certain elasticity of the telescopic elastic plate 202, the infusion bottle can be completely stuck inside the placement ring seat 101, which is conducive to limiting the position of the infusion bottle.
