Description

Technical Field

[0001] This utility model relates to the field of infusion equipment technology, specifically to an identification device for distinguishing between infusion tubes and feeding tubes. Background Technology

[0002] A feeding pump is a nasogastric tube-operated infusion pump that delivers water, nutritional solutions, and homemade formula or milk of a specific concentration to patients to improve their nutritional status. Because there are significant differences between infusion and feeding modes, it is necessary to identify the type of tube when administering the medication. However, in the current medical context, a healthcare worker often needs to care for many patients. To avoid medical accidents, medical personnel usually need to double-check medications, but this not only leads to the mental and physical exhaustion of healthcare workers but also causes patients to wait for extended periods.

[0003] Therefore, there is an urgent need for an automated device to quickly identify infusion tubing and feeding tubing. Utility Model Content

[0004] This invention proposes an identification device for distinguishing between infusion tubes and feeding tubes, which solves the problem of low identification efficiency in existing methods for distinguishing between infusion tubes and feeding tubes.

[0005] The technical solution of this utility model is as follows: A device for distinguishing between infusion tubes and feeding tubes, comprising an identification component, a first stop clamp, and a second stop clamp, wherein the first stop clamp is connected to the infusion tube, the second stop clamp is connected to the feeding tube, and the length of the first stop clamp is greater than the length of the second stop clamp; the identification component includes:

[0006] The outer shell is identified, and an inner cavity is identified, into which both the first and second liquid-stopping clips can be inserted.

[0007] A clamping component is disposed inside the identification housing. The clamping component includes a hook, which is used to fix the first or second liquid-stopping clamp inserted into the identification cavity.

[0008] A detector is disposed in the identification cavity and includes a detector rod and a magnet. The detector rod is slidably disposed in the identification cavity. The magnet is connected to the middle of the detector rod and moves synchronously with the detector rod. The first end of the detector rod can extend to the outside of the identification cavity after sliding. The second end of the detector rod contacts the first liquid stop clamp or the second liquid stop clamp.

[0009] A photoelectric switch is disposed on the outside of the identification housing and is used to sense the detection rod;

[0010] A Hall switch is disposed on the outside of the identification housing and is used to sense the magnet;

[0011] When the first liquid-stopping clamp is inserted into the identification cavity, the Hall switch senses the magnet and the photoelectric switch senses the probe rod; when the second liquid-stopping clamp is inserted into the identification cavity, the Hall switch senses the magnet.

[0012] As a further technical solution, the identification shell has a penetration opening, the second end of the probe rod faces the penetration opening, and the first liquid stop clamp and the second liquid stop clamp enter the identification cavity through the penetration opening.

[0013] As a further technical solution, the detector also includes a first reset spring, one end of which abuts against the inner wall of the identification cavity, and the other end abuts against the second end of the detector rod.

[0014] As a further technical solution, the first reset spring is sleeved in the middle of the probe rod.

[0015] As a further technical solution, the clamping member also includes:

[0016] A rotating shaft is disposed in the identification cavity, and the first end of the hook is rotatably connected to the rotating shaft;

[0017] The second reset spring is located in the identification cavity. One end of the second reset spring abuts against the inner wall of the identification cavity, and the other end abuts against the middle of the hook.

[0018] As a further technical solution, the clamping member also includes a limiting block, which is slidably disposed in the identification cavity. The limiting block is used to prevent the hook from suddenly resetting when it is lifted.

[0019] As a further technical solution, the second end of the hook has a hand-operated part and a hook-shaped part. The hook-shaped part is used to fix the infusion tube or nutrition tube to prevent the first or second stop clamp from coming out of the identification cavity during identification.

[0020] As a further technical solution, the second end of the hook also has an anti-rotation part, which contacts the limiting block to separate the hook-shaped part from the infusion tube or nutrition tube.

[0021] As a further technical solution, both the first liquid stop clamp and the second liquid stop clamp have a receiving hole in the middle.

[0022] The working principle and beneficial effects of this utility model are as follows: The identification device for distinguishing between infusion tubes and feeding tubes includes an identification component, a first stop clamp, and a second stop clamp. The first stop clamp is connected to the infusion tube, and the second stop clamp is connected to the feeding tube. The length of the first stop clamp is greater than the length of the second stop clamp. The identification component distinguishes between the infusion tube and the feeding tube by identifying the first and second stop clamps. The identification component includes an identification housing, a clamping element, a detector, a photoelectric switch, and a Hall effect switch. The identification housing has an internal cavity, with the clamping element and detector located within it. The photoelectric switch is connected to the identification housing and located outside the internal cavity. The Hall effect switch is located outside the identification housing, with the photoelectric switch and Hall effect switch connected to different sides of the identification housing. The clamping element is located inside the identification housing and includes a hook for securing a first or second liquid-stop clamp inserted into the identification housing. The detector includes a magnet and a probe rod. The magnet is mounted on the probe rod and located within the internal cavity. The probe rod can slide within the internal cavity, and the magnet moves with the probe rod. After moving a certain distance, the first end of the probe rod can extend outside the identification housing and be detected by the photoelectric switch. During the movement of the probe rod, since it also moves, only... At this point, a certain amount of movement will be detected by the Hall switch. When the first stop clamp is inserted into the identification cavity of the identification shell, it will push against the second end of the probe rod, causing the probe rod to move. Since the length of the first stop clamp is greater than that of the second stop clamp, the probe rod will move a longer distance. After the movement is completed, the probe rod will be detected by the photoelectric switch, and the magnet will also be detected by the Hall switch. When the second stop clamp is inserted into the identification cavity of the identification shell, it will also push against the second end of the probe rod. However, since the length of the second stop clamp is smaller, the probe rod will move a limited distance. After the movement is completed, only the magnet will be detected by the Hall switch, and the photoelectric switch will not detect the first end of the probe rod. Therefore, under these conditions, the infusion tube and the feeding tube can be identified by recognizing the first and second stop clamps.

[0023] When medical staff need to identify infusion tubes or feeding tubes, they only need to insert the stop clamp connected to the tube into the identification device provided by this invention. If both the Hall switch and the photoelectric switch react, it proves that it is an infusion tube; if only the Hall switch reacts, it proves that it is a feeding tube. This identification method greatly reduces the difficulty for medical staff to distinguish between infusion tubes and feeding tubes and improves identification efficiency.

[0036] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0037] like Figures 1-8 As shown, this embodiment proposes an identification device for distinguishing between infusion tubing and feeding tubing, including an identification component, a first stop clamp 1, and a second stop clamp 2. The first stop clamp 1 is connected to the infusion tubing, and the second stop clamp 2 is connected to the feeding tubing. The length of the first stop clamp 1 is greater than the length of the second stop clamp 2. The identification component includes:

[0038] The outer shell is identified, and an inner cavity is identified, into which both the first liquid-stopping clip 1 and the second liquid-stopping clip 2 can be inserted;

[0039] A clamping component is provided inside the identification housing 3. The clamping component includes a hook 4, which is used to fix the first liquid-stopping clamp 1 or the second liquid-stopping clamp 2 that is inserted into the identification cavity.

[0040] The detector is set in the identification cavity and includes a detector rod 5 and a magnet 6. The detector rod 5 is slidably set in the identification cavity. The magnet 6 is connected to the middle of the detector rod 5 and moves synchronously with the detector rod 5. The first end of the detector rod 5 can extend to the outside of the identification cavity after sliding. The second end of the detector rod 5 contacts the first liquid stop clamp 1 or the second liquid stop clamp 2.

[0041] A photoelectric switch 7 is disposed on the outside of the identification housing 3 and is used to sense the detection rod 5;

[0042] Hall switch 8 is disposed on the outside of the identification housing 3 and is used to sense the magnet 6;

[0043] When the first liquid-stopping clamp 1 is inserted into the identification cavity, the Hall switch 8 senses the magnet 6 and the photoelectric switch 7 senses the probe rod 5; when the second liquid-stopping clamp 2 is inserted into the identification cavity, the Hall switch 8 senses the magnet 6.

[0044] In this embodiment, the identification device for distinguishing between infusion tubing and feeding tubing includes an identification component, a first stop clamp 1, and a second stop clamp 2. The first stop clamp 1 is connected to the infusion tubing, and the second stop clamp 2 is connected to the feeding tubing. The length of the first stop clamp 1 is greater than the length of the second stop clamp 2. The identification component distinguishes between the infusion tubing and the feeding tubing by identifying the first stop clamp 1 and the second stop clamp 2. The identification component includes an identification housing 3, a clamping element, a detector, a photoelectric switch 7, and a Hall switch 8. The identification housing 3 has an internal identification cavity. The clamping element and the detector are both located within the internal identification cavity. The photoelectric switch 7 is connected to the identification housing 3 and located outside the internal identification cavity. The Hall switch 8 is located outside the identification housing 3, and the photoelectric switch 7 and Hall switch 8 are respectively connected to different sides of the identification housing 3. The clamping element is located inside the identification housing 3 and includes a hook 4 for fixing a first liquid-stopping clamp 1 or a second liquid-stopping clamp 2 inserted into the identification housing 3. The detector includes a magnet 6 and a detector rod 5. The magnet 6 is mounted on the detector rod 5 and located within the internal identification cavity. The detector rod 5 can slide within the internal identification cavity, and the magnet 6 moves along with the detector rod 5. After moving a certain distance, the first end of the detector rod 5 can extend outside the identification housing 3 and be detected by the photoelectric switch 7. During the movement of the detector rod 5, the detector also moves. As long as there is a certain amount of movement, it will be sensed by Hall switch 8. At this time, when the first stop clamp 1 is inserted into the recognition cavity of the recognition housing 3, the first stop clamp 1 will push the second end of the probe rod 5, and then the probe rod 5 will move. Since the length of the first stop clamp 1 is greater than that of the second stop clamp 2, the probe rod 5 will move a longer distance. After the movement is completed, the probe rod 5 will be sensed by photoelectric switch 7, and at the same time, the magnet 6 will be sensed by Hall switch 8. When the second stop clamp 2 is inserted into the recognition cavity of the recognition housing 3, the second stop clamp 2 will also push the second end of the probe rod 5. However, since the length of the second stop clamp 2 is smaller, the probe rod 5 will move a limited distance. After the movement is completed, only the magnet 6 will be sensed by Hall switch 8, and the photoelectric switch 7 will not sense the first end of the probe rod 5. Therefore, under these judgment conditions, the infusion tube and the feeding tube can be identified by identifying the first stop clamp 1 and the second stop clamp 2.

[0045] When medical staff need to identify infusion tubes or feeding tubes, they only need to insert the stop clamp connected to the tube into the identification device provided by this invention. If both the Hall switch and the photoelectric switch react, it proves that it is an infusion tube; if only the Hall switch reacts, it proves that it is a feeding tube. This identification method greatly reduces the difficulty for medical staff to distinguish between infusion tubes and feeding tubes and improves identification efficiency.

[0046] Furthermore, such as Figures 1-4As shown, in this embodiment, the identification shell 3 is provided with an inlet, the second end of the probe 5 faces the inlet, and the first liquid stop clamp 1 and the second liquid stop clamp 2 enter the identification cavity through the inlet.

[0047] In this embodiment, in order to allow the first liquid-stopping clip 1 and the second liquid-stopping clip 2 to penetrate into the identification housing 3, and to prevent substances outside the identification housing 3 from affecting other objects in the identification cavity, an inlet is opened on the identification housing 3. The second end of the probe rod 5 is directly opposite the inlet. The first liquid-stopping clip 1 and the second liquid-stopping clip 2 can enter into the identification cavity through the inlet. During the insertion of the first liquid-stopping clip 1 or the second liquid-stopping clip 2, it will contact the second end of the probe rod 5 and push the probe rod 5.

[0048] Furthermore, such as Figure 4 As shown, this embodiment proposes that the detector also includes a first reset spring 9, one end of which abuts against the inner wall of the identification cavity, and the other end abuts against the second end of the detector rod 5.

[0049] In this embodiment, the detector also includes a first reset spring 9, which is located in the identification cavity. One end of the first reset spring 9 abuts against the inner wall of the identification cavity, and the other end abuts against the second end of the detector rod 5. Since the detector rod 5 will move under the push of the first liquid stop clamp 1 or the second liquid stop clamp 2, the detector rod 5 needs to be reset after the first liquid stop clamp 1 or the second liquid stop clamp 2 is removed. The first reset spring 9 can make the detector rod 5 return to its original position, avoiding manual operation.

[0050] Furthermore, such as Figure 4 As shown in the figure, in this embodiment, the first reset spring 9 is sleeved in the middle of the probe rod 5.

[0051] In this embodiment, to reduce the overall space occupied by the device, the first reset spring 9 is sleeved in the middle of the probe rod 5. The second end of the probe rod 5 has a protrusion near the magnet 6. One end of the first reset spring 9 is connected to the inner wall of the identification cavity, and the other end is connected to the protrusion. This ensures that the first reset spring 9 occupies a small space, thereby ensuring that the overall device is miniaturized.

[0052] Furthermore, such as Figure 4 As shown in the figure, this embodiment proposes that the clamping member further includes:

[0053] A rotating shaft 10 is set in the identification cavity, and the first end of the hook 4 is rotatably connected to the rotating shaft 10.

[0054] The second reset spring 11 is located in the identification cavity. One end of the second reset spring 11 abuts against the inner wall of the identification cavity, and the other end abuts against the middle of the hook 4.

[0055] In this embodiment, the clamping component also includes a rotating shaft 10 and a second return spring 11. The rotating shaft 10 is disposed in the recognition cavity, and the first end of the hook 4 is rotatably connected to the rotating shaft 10. The other end of the hook 4 can rotate freely. The second return spring 11 is located in the recognition cavity, with one end abutting against the inner wall of the recognition cavity and the other end abutting against the middle of the hook 4. When inserting the first stop clamp 1 or the second stop clamp 2, the free end of the hook 4 needs to rotate to avoid obstruction (because the first stop clamp 1 has an infusion tube and the second stop clamp 2 has a nutrition tube, and the hook 4 actually avoids obstruction of the infusion tube or nutrition tube). After inserting the first stop clamp 1 or the second stop clamp 2 into the recognition cavity, the hook 4 needs to reset to lock the infusion tube or nutrition tube in place, preventing the infusion tube or nutrition tube from moving arbitrarily.

[0056] Furthermore, such as Figure 6 As shown, this embodiment proposes that the clamping member also includes a limiting block 12, which is slidably disposed in the identification cavity. The limiting block 12 is used to prevent the hook 4 from suddenly resetting when it is lifted.

[0057] In this embodiment, the clamping member also includes a limiting block 12, which is movably disposed in the recognition cavity. During the insertion of the first liquid-stopping clamp 1 or the second liquid-stopping clamp 2, the limiting block 12 will move along with the first liquid-stopping clamp 1 or the second liquid-stopping clamp 2. During the movement, due to the presence of the limiting block 12, the hook 4 will be obstructed. This obstruction prevents the hook 4 from resetting. Preventing the hook 4 from resetting can prevent the hook 4 from obstructing the movement of the first liquid-stopping clamp 1 or the second liquid-stopping clamp 2.

[0058] Furthermore, such as Figure 4 and Figure 7 As shown, this embodiment proposes that the second end of the hook 4 has a hand-operated part 41 and a hook-shaped part 42. The hook-shaped part 42 is used to fix the infusion tube or nutrition tube to prevent the first stop clamp 1 or the second stop clamp 2 from coming out of the identification cavity during identification.

[0059] In this embodiment, for ease of operation, the second end of the hook 4 has a hand-operated part 41 and a hook-shaped part 42. The hand-operated part 41 has anti-slip texture. The operator rotates the hook 4 through the hand-operated part 41. After the first stop clamp 1 or the second stop clamp 2 is inserted into the identification cavity, the hook 4 is reset. Then the hook-shaped part 42 of the hook 4 will be locked on the outside of the infusion tube or nutrition tube, thereby preventing the infusion tube or nutrition tube from coming out of the identification shell 3 along with the first stop clamp 1 or the second stop clamp 2.

[0060] Furthermore, such as Figure 4 and Figure 7As shown, this embodiment proposes that the second end of the hook 4 also has an anti-rotation part 43, which contacts the limiting block 12 to separate the hook-shaped part 42 from the infusion tube or nutrition tube.

[0061] In this embodiment, the second end of the hook 4 also has an anti-rotation part 43. The anti-rotation part 43 is a protrusion and is used to contact the limiting block 12. When the anti-rotation part 43 contacts the limiting block 12, it can prevent the hook-shaped part 42 from contacting the infusion tube or the feeding tube.

[0062] Furthermore, such as Figure 8 As shown in the figure, this embodiment proposes that both the first liquid stop clamp 1 and the second liquid stop clamp 2 have a receiving hole in the middle.

[0063] In this embodiment, both the first stop clamp 1 and the second stop clamp 2 have a receiving hole in the middle, which is used to insert an infusion tube or a feeding tube.

[0064] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
