Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and particularly to an infusion alarm device. Background Art

[0002] When performing intravenous drip infusion for a patient in a hospital or a home ward, it is necessary to constantly monitor the remaining liquid volume in the medicine bottle. When the medicine bottle is emptied, it may cause the patient's venous blood return. If the drip tube is emptied and the medicine bottle is hurriedly replaced for the patient without expelling the air in the tube, it may even endanger the patient's life. Therefore, an infusion alarm is usually clamped or adhered to the infusion tube. The infusion alarm can detect the liquid level in the infusion tube and issue an alarm when the liquid level drops to the position of the infusion alarm to remind the medical staff to change the medicine.

[0003] The end of the infusion tube is inserted into the rubber cap at the head of the infusion container through a needle, so that the liquid in the infusion container can enter the infusion tube to complete the infusion operation. The needle and the infusion container are connected to each other by friction. Setting an infusion alarm on the infusion tube will increase the overall weight of the infusion tube, increase the force exerted on the needle away from the infusion container, and easily cause the needle to separate from the rubber cap, interrupting the infusion operation.

Detailed Embodiments

[0027] In order to more clearly understand the above-mentioned objects, features, and advantages of the present disclosure, the following will further describe the solutions of the present disclosure. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0028] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. However, the present disclosure may be implemented in other ways different from those described herein. Obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] Referring to Figures 1 to 3 As shown, an embodiment of the present disclosure provides an infusion alarm device, which includes a detection clip 1 and a limit clip 2. The detection clip 1 is used for clamping an infusion tube 31. A sensor 14 and an alarm 13 are provided on the detection clip 1. The sensor 14 is used for detecting the liquid level in the infusion tube 31, and the alarm is electrically connected to the sensor 14; the limit clip 2 is connected to one side of the detection clip 1, and the limit clip 2 is used for clamping the head of the infusion container 32.

[0030] Specifically, the detection clip 1 may optionally include two rotatably connected plates, so that the two plates can be brought closer to each other to clamp the infusion tube 31. An optoelectronic detector may be optionally provided on the detection clip 1 as the sensor 14, and the sensor 14 is arranged facing the infusion tube 31. When the liquid level in the infusion tube 31 drops to the position of the detection clip 1, the sensor 14 detects the liquid level and sends a signal to the alarm 13, and the alarm 13 receives the signal and issues an alarm to remind medical staff to replace the infusion container 32.

[0031] The above-mentioned infusion container 32 may be optionally a glass medicine bottle or a plastic medicine bag. The head of the infusion container 32 has a cylindrical structure, and there is a boss on the outer side surface of the cylindrical structure. The needle at the end of the infusion tube 31 passes through the head of the infusion container 32, and the limit clip 2 clamps on the boss at the head of the infusion container 32.

[0032] The alarm 13 may optionally include a buzzer. After the alarm 13 receives the signal emitted by the sensor 14, the buzzer is activated to remind medical staff. Of course, it may also be optionally that the alarm 13 includes a buzzer and a light bulb. After the alarm 13 receives the signal sent by the sensor 14, the buzzer is activated and the light bulb starts to flash to remind medical staff.

[0033] The above-mentioned limit clip 2 may optionally include two clip pieces, one of the clip pieces is connected to the detection clip 1, so that when the detection clip 1 clamps on the infusion tube 31, the limit clip 2 clamps on the head of the infusion container 32, and the clamping of the limit clip 2 on the head of the infusion container 32 shares the weight of the detection clip 1.

[0034] When the infusion alarm device provided by the embodiment of the present disclosure is specifically used, the infusion tube 31 is connected to the head of the infusion container 32. The limiting clip 2 first clamps the head of the infusion container 32, and then with the connection between the limiting clip 2 and the head of the infusion container 32 as the fulcrum, the detection clip 1 is moved close to the infusion tube 31 to be clamped and connected to the infusion tube 31. The sensor 14 on the detection clip 1 detects the liquid level in the infusion tube 31. When the liquid level in the infusion tube 31 drops to the position of the sensor 14, the sensor 14 sends a signal to the alarm 13, and the alarm 13 receives the signal and issues an alarm to remind the medical staff to replace the infusion container 32.

[0035] The infusion alarm device provided by the embodiment of the present disclosure includes a detection clip 1 and a limiting clip 2. The detection clip 1 is used to clamp the infusion tube 31. A sensor 14 and an alarm 13 are provided on the detection clip 1. The sensor 14 is used to detect the liquid level in the infusion tube 31, and the alarm 13 is electrically connected to the sensor 14. The limiting clip 2 is connected to one side of the detection clip 1, and the limiting clip 2 is used to clamp the head of the infusion container 32. By clamping the detection clip 1 on the infusion tube 31 to detect the liquid level in the infusion tube 31, and at the same time clamping the limiting clip 2 on the head of the infusion container 32, the infusion alarm device is connected to both the infusion tube 31 and the infusion container 32. The self-weight of the detection clip 1 is transmitted to the infusion container 32 through the limiting clip 2, avoiding the increase in the downward force on the infusion tube 31 caused by the clamping of the detection clip 1 on the infusion tube 31, and improving the connection stability between the infusion tube 31 and the infusion container 32 when using the infusion alarm device to detect the infusion state.

[0036] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the detection clip 1 includes a first clip piece 11 and a second clip piece 12. The first clip piece 11 is rotatably connected to the second clip piece 12, and a limiting elastic member is connected between the first clip piece 11 and the second clip piece 12. The limiting elastic member drives the first clip piece 11 and the second clip piece 12 to move towards each other.

[0037] The sensor 14 is disposed on either the first clip piece 11 or the second clip piece 12, and the alarm 13 is disposed on either the first clip piece 11 or the second clip piece 12.

[0038] Either the first clip piece 11 or the second clip piece 12 is connected to the limiting clip 2. With such a setting, the first clip piece 11 and the second clip piece 12 move away from each other so that the infusion tube 31 can enter between the first clip piece 11 and the second clip piece 12. When the first clip piece 11 and the second clip piece 12 move towards each other, they can clamp the infusion tube 31, thereby conveniently clamping the infusion tube 31 by the first clip piece 11 and the second clip piece 12, enabling the sensor 14 to monitor the liquid level position in the infusion tube 31. When the liquid level in the infusion tube 31 drops between the first clip piece 11 and the second clip piece 12, the alarm 13 issues an alarm to remind the medical staff to replace the infusion container 32.

[0039] Specifically, the first clip 11 and the second clip 12 can both be selected as rectangular sheet bodies. The end of the first clip 11 is rotatably connected to the end of the second clip 12. A spring can be selected to be connected between the first clip 11 and the second clip 12 as a limiting elastic member. When the first clip 11 and the second clip 12 are arranged oppositely and in contact with each other, the limiting elastic member is in a relaxed state; when a force is applied to the first clip 11 and the second clip 12 to make the first clip 11 and the second clip 12 rotate away from each other, the limiting elastic member elongates. When the force applied to the first clip 11 and the second clip 12 is stopped, the elastic force of the limiting elastic member makes the first clip 11 and the second clip 12 approach each other and fit together.

[0040] When the above-mentioned infusion tube 31 is between the first clip 11 and the second clip 12, the first clip 11 and the second clip 12 are driven by the limiting elastic member to approach each other, so that both the first clip 11 and the second clip 12 are in contact with the infusion tube 31. The elastic modulus of the limiting elastic member is selected according to the actual situation, so that the first clip 11 and the second clip 12 keep in contact with the infusion tube 31, and the first clip 11 and the second clip 12 will not cause large deformation of the infusion tube 31, avoiding the clamping connection between the first clip 11 and the second clip 12 and the infusion tube 31 from hindering the flow of liquid in the infusion tube 31.

[0041] The above-mentioned sensor 14 can be selected to be arranged on the first clip 11, and the alarm 13 is arranged on the first clip 11. The sensor 14 and the alarm 13 are electrically connected by wires or data lines; of course, it can also be selected that the sensor 14 is arranged on the first clip 11, the alarm 13 is arranged on the second clip 12, and the sensor 14 and the alarm 13 are electrically connected by wires or data lines.

[0042] Of course, it can also be selected that the sensor 14 is arranged on the second clip 12, the alarm 13 is arranged on the second clip 12, and the sensor 14 and the alarm 13 are electrically connected by wires or data lines; or it is not limited to the sensor 14 being arranged on the second clip 12, the alarm 13 being arranged on the first clip 11, and the sensor 14 and the alarm 13 being electrically connected by wires or data lines.

[0043] The above-mentioned limiting clip 2 can be selected to be connected to the first clip 11 through a plate body or a rope body. Of course, it can also be selected that the limiting clip 2 is connected to the second clip 12 through a plate body or a rope body.

[0044] Refer to Figure 1 and Figure 3As shown, in some embodiments, a sensor 14 and an alarm 13 are provided on the first clip 11, and the detection end of the sensor 14 is disposed on the side of the first clip 11 facing the second clip 12. With this arrangement, the sensor 14 and the alarm 13 are concentrated on the first clip 11, which facilitates the manufacture of the infusion alarm device. When the infusion tube 31 is disposed between the first clip 11 and the second clip 12, the detection end of the sensor 14 can monitor the liquid level in the infusion tube 31.

[0045] Specifically, the interior of the first clip 11 can be selected to be hollow, the sensor 14 is disposed inside the first clip 11, and a window is provided on the side surface of the first clip 11 facing the second clip 12, so that the detection end of the sensor 14 is exposed on the side of the first clip 11 facing the second clip 12 through the window; when the infusion tube 31 is clamped between the first clip 11 and the second clip 12, the detection end of the sensor 14 can detect the liquid level in the infusion tube 31.

[0046] Refer to Figure 1 and Figure 3 As shown, in some embodiments, a receiving groove 111 is formed by recessing on the side of the first clip 11 facing the second clip 12, the detection end of the sensor 14 is disposed inside the receiving groove 111, the receiving groove 111 penetrates the first clip 11 in a direction perpendicular to the side of the first clip 11 facing the second clip 12, and the receiving groove 111 is used to receive a part of the infusion tube 31. With this arrangement, the receiving groove 111 can position the infusion tube 31 between the first clip 11 and the second clip 12, and a part of the infusion tube 31 is located in the receiving groove 111, so that the fitting of the first clip 11 and the second clip 12 will not cause large deformation of the infusion tube 31, and the flow of the liquid in the infusion tube 31 is prevented from being obstructed when the first clip 11 and the second clip 12 clamp the infusion tube 31.

[0047] Specifically, the receiving groove 111 can be selected as an arc-shaped groove body formed by recessing on the side of the first clip 11 facing the second clip 12. When the first clip 11 and the second clip 12 are clamped on the infusion tube 31, the first clip 11 and the second clip 12 are on both sides of the infusion tube 31 in the horizontal direction, the receiving groove 111 penetrates the first clip 11 in the vertical direction, and the notch of the receiving groove 111 is formed on the side surface of the first clip 11 facing the second clip 12.

[0048] When the first clip 11 and the second clip 12 clamp the infusion tube 31, the infusion tube 31 enters the receiving groove 111 through the notch of the receiving groove 111, so that a part of the infusion tube 31 is in the receiving groove 111, and the remaining part of the infusion tube 31 protrudes from the notch of the receiving groove 111. The first clip 11 and the second clip 12 approach each other, so that the inner wall of the receiving groove 111 abuts against the infusion tube 31, and the second clip 12 abuts against the part of the infusion tube 31 exposed outside the notch of the receiving groove 111, so that the first clip 11 and the second clip 12 clamp the infusion tube 31.

[0049] Referring to Figure 1 and Figure 3 As shown, in some embodiments, the limiting clip 2 includes a main body portion 22 and two clamping portions 21. The two clamping portions 21 are connected to the main body portion 22. The two clamping portions 21 are arranged opposite to each other and can approach and separate from each other. The main body portion 22 or any one of the clamping portions 21 is connected to the detection clip 1. With such an arrangement, the main body portion 22 serves as the installation base for the two clamping portions 21. When the two clamping portions 21 move away from each other, the head of the infusion container 32 can enter between the two clamping portions 21, and then when the two clamping portions 21 approach each other, the head of the infusion container 32 can be clamped.

[0050] Specifically, the main body portion 22 can be selected as a rectangular plate body, or it can also be selected as a block structure. The two clamping portions 21 are connected to the opposite side edges of the main body portion 22. The clamping portions 21 can be selected as elastic plastic sheets or metal sheets. The ends of the two clamping portions 21 away from the main body portion 22 abut against each other. When the limiting clip 2 clamps the head of the infusion container 32, the two clamping portions 21 first elastically deform and move away from each other, and then the head of the infusion container 32 enters between the two clamping portions 21. Under the action of their own elastic forces, the two clamping portions 21 approach each other to clamp on both sides of the head of the infusion container 32.

[0051] Certainly, it is also possible to select that the clamping portions 21 are arranged on both sides of the main body portion 22, and the clamping portions 21 are rotatably connected to the main body portion 22. A spring is connected between the two clamping portions 21. The spring drives the ends of the two clamping portions 21 on the same side of the main body portion 22 to abut against each other. When the limiting clip 2 clamps the head of the infusion container 32, the clamping portions 21 rotate relative to the main body portion 22 to make the two clamping portions 21 move away from each other. The head of the infusion container 32 enters between the two clamping portions 21, and the elastic force of the spring drives the ends of the two clamping portions 21 to approach each other to clamp on both sides of the head of the infusion container 32.

[0052] The above-mentioned main body portion 22 can be selected to be connected to the detection clip 1. Certainly, it is also possible to select that one clamping portion 21 is connected to the main body portion 22.

[0053] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the clamping portions 21 are elastic and the two clamping portions 21 abut against each other. With such an arrangement, the clamping portions 21 are elastic by themselves, so that the two clamping portions 21 can move away from each other under their own elastic action to enable the head of the infusion container 32 to enter between the two clamping portions 21, and then the two clamping portions 21 can clamp the head of the infusion container 32 under the action of their own elastic forces.

[0054] Specifically, the clamping part 21 is elastic. The two clamping parts 21 abut against each other at the ends on the same side of the main body part 22. The two clamping parts 21 can be elastically deformed to move away from each other, enabling the head of the infusion container 32 to enter between the two clamping parts 21. After the head of the infusion container 32 enters between the two clamping parts 21, the two clamping parts 21 approach each other under their own elastic action and abut against the boss on the head of the infusion container 32, thereby clamping the head of the infusion container 32 by the two clamping parts 21.

[0055] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the two ends of the clamping part 21 are respectively a clamping end 211 and a driving end 212. One clamping part 21 is connected to each of the opposite side edges of the main body part 22. The middle part of the clamping part 21 is rotatably connected to the main body part 22. The two clamping ends 211 are arranged oppositely, and the two driving ends 212 are arranged oppositely.

[0056] A driving elastic member 23 is connected between the two clamping parts 21. The driving elastic member 23 drives the two clamping ends 211 to approach each other, so that the two clamping ends 211 clamp the head of the infusion container 32. With such a setting, the clamping ends 211 can approach each other under the drive of the driving elastic member 23, and the elastic force of the driving elastic member 23 enables the two clamping ends 211 to stably clamp the head of the infusion container 32.

[0057] Specifically, the clamping part 21 can be selected as a plate structure. The two ends of the clamping part 21 can be respectively a clamping end 211 and a driving end 212. The middle part of the clamping part 21 is rotatably connected to the edge of the main body part 22, so that the clamping end 211 and the driving end 212 are respectively on both sides of the main body part 22, and the clamping ends 211 of the two clamping parts 21 are on the same side of the main body part 22. A spring can be selected to be connected between the two clamping parts 21 as the driving elastic member 23. The spring is arranged along the direction from one clamping part 21 towards the other clamping part 21. The spring is arranged on the side of the main body part 22 close to the driving end 212. The elastic force of the spring drives the two driving ends 212 to move away from each other, so that the two clamping ends 211 approach each other. Of course, the driving elastic member 23 can also be arranged on the side of the main body part 22 close to the clamping end 211, and the elastic force of the spring drives the two clamping ends 211 to approach each other.

[0058] When the head of the above-mentioned infusion container 32 is between the two clamping ends 211, the driving elastic member 23 drives the two clamping ends 211 to approach each other, so that the two clamping ends 211 clamp the head of the infusion container 32. The clamping end 211 of the clamping part 21 can be selected as a hook structure, so that the hook structure is clamped and connected to the boss on the head of the infusion container 32.

[0059] Referring to Figure 1 and Figure 2As shown, in some embodiments, a relief groove is formed by recessing one side edge of the main body portion 22 perpendicular to the relative direction of the two clamping portions 21. The relief groove is used to accommodate the infusion tube 31. With this arrangement, the relief groove accommodates the infusion tube 31, so that when the main body portion 22 is below the infusion container 32, the infusion tube 31 can hang down naturally, facilitating the flow of liquid in the infusion tube 31.

[0060] Specifically, a relief groove is formed by recessing one side edge of the main body portion 22 perpendicular to the relative direction of the two clamping portions 21. When the two clamping ends 211 clamp the head of the infusion container 32, the main body portion 22 can be selected to be below the head of the infusion container 32. The infusion tube 31 enters the relief groove through the notch of the relief groove, so that when the clamping portion 21 is arranged in the vertical direction, the infusion tube 31 can hang down naturally under the action of gravity in the relief groove, facilitating the flow of liquid in the infusion tube 31.

[0061] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the limit clip 2 and the detection clip 1 are connected to each other by a connecting rope 24. The limit clip 2 is clamped and connected to the head of the infusion container 32, and when the detection clip 1 is clamped and connected to the infusion tube 31, the connecting rope 24 is in a tensioned state. With this arrangement, the structure of the connecting rope 24 connecting the limit clip 2 and the detection clip 1 is simple, and when storing the infusion alarm device, the connecting rope 24 can be bent to stack the limit clip 2 and the detection clip 1, reducing the volume of the infusion alarm device.

[0062] Specifically, the connecting rope 24 can be selected as a flexible rope. One end of the connecting rope 24 is connected to the first clip piece 11, and the other end is connected to one clamping portion 21 of the limit clip 2. Of course, it can also be selected that one end of the connecting rope 24 is connected to the first clip piece 11, and the other end is connected to the main body portion 22 of the limit clip 2.

[0063] When the limit clip 2 clamps the head of the infusion container 32, the detection clip 1 hangs down naturally through the connecting rope 24, and then the detection clip 1 is clamped and connected to the infusion tube 31, so that the connecting rope 24 is in a tensioned state, and thus the limit clip 2 bears the weight of the detection clip 1.

[0064] Refer to Figure 1 and Figure 2 As shown, in some embodiments, the sensor 14 includes a photoelectric sensor, and the alarm 13 includes a buzzer and a light bulb. The photoelectric sensor 14 is electrically connected to the buzzer and the light bulb. With this arrangement, the monitoring accuracy of the photoelectric sensor is high, and it can accurately monitor the liquid level in the infusion tube 31; the buzzer and the light bulb of the alarm 13 can respectively remind medical staff from the aspects of hearing and vision.

[0065] Specifically, when light passes through the infusion tube 31, the refraction angle of the light is different when the infusion tube 31 is filled with liquid and when the light in the infusion tube 31 is gas. Therefore, when the liquid level in the infusion tube 31 drops to the sensor 14, the photoelectric sensor of the sensor 14 can detect the liquid level in the infusion tube 31, so that the photoelectric sensor monitors the position of the liquid level in the infusion tube 31.

[0066] After the buzzer in the above-mentioned alarm 13 is started, it can emit a sound to remind medical staff. After the alarm 13 receives the signal from the sensor 14, the light bulb can emit light, thus alerting the medical staff.

[0067] When the infusion alarm device provided by the present disclosure is specifically used, first drive the driving ends 212 of the two clamping parts 21 to approach each other, so that the two clamping ends 211 move away from each other, and the head of the infusion container 32 enters between the two clamping ends 211. Stop applying force to the two driving ends 212. Under the action of the driving elastic member 23, the two clamping ends 211 approach each other to clamp the head of the infusion container 32. Rotate the limit clip 2 with the connection between the clamping end 211 and the head of the infusion container 32 as the fulcrum, so that the main body part 22 is located below the head of the infusion container 32, and the infusion tube 31 enters the avoidance groove of the main body part 22, so that the infusion tube 31 hangs down naturally.

[0068] When the limit clip 2 rotates, the detection clip 1 rotates with the limit clip 2 to the infusion tube 31, driving the first clip 11 and the second clip 12 to move away from each other, putting the infusion tube 31 into the accommodation groove 111. Stop applying external force to the first clip 11 and the second clip 12. The limit elastic member drives the first clip 11 and the second clip 12 to approach each other, so that the first clip 11 and the second clip 12 clamp the infusion tube 31, and the weight of the detection clip 1 is borne by the limit clip 2.

[0069] The sensor 14 on the first clip 11 monitors the liquid level in the infusion tube 31. When the liquid level in the infusion tube 31 drops between the first clip 11 and the second clip 12, the sensor 14 sends a signal to the alarm 13. The buzzer of the alarm 13 is started to emit a sound, and the light bulb is started to emit light, so that the alarm 13 can remind the medical staff to replace the infusion container.
