Abstract
Description
Technical Field
[0001] This utility model relates to an infusion monitor with a pressure sensor drop protection structure. Background Technology
[0002] Most infusion monitors on the market monitor the infusion process based on weighing. The hanging ring is rigidly connected to the fixed end of the precision sensor, and the hook is rigidly fixed to the force-bearing end of the precision sensor. If the monitor is accidentally dropped on the ground and hits the hook during use, the precision sensor will be subjected to a great impact, exceeding the rated value that the pressure sensor can withstand, causing the precision sensor to be overloaded and damaged, resulting in inaccurate monitoring and unusable monitor. Utility Model Content
[0003] The main purpose of this invention is to provide an infusion monitor with a pressure sensor drop protection structure, in order to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the present invention proposes an infusion monitor with a pressure sensor anti-drop protection structure, comprising a housing with a hanging ring, a sensor unit disposed inside the housing, a buffer unit, and a hook located outside the housing. The sensor is connected to the hanging ring, and the hook and the sensor unit are connected through the buffer unit. The hook has a buffer gap with the housing when no external force is applied.
[0005] In one embodiment, the buffer unit includes a hook connector, and the sensor unit is fixedly mounted on the hook connector.
[0006] In one embodiment, the buffer unit further includes a buffer compression spring disposed within the hook connector.
[0007] In one embodiment, the hook connector includes a first mounting portion and a second mounting portion. The first mounting portion has a cavity for accommodating the second mounting portion. The buffer compression spring is disposed in the cavity and abuts against the opposite sides of the first mounting portion and the second mounting portion, respectively. The second mounting portion passes through the bottom of the outer shell and is connected to the hook.
[0008] In one embodiment, the second mounting portion includes a connecting shaft and abutment portions protruding outward from both sides of the connecting shaft. The two ends of the buffer compression spring are respectively connected to the abutment portions and the first mounting portion, and the two ends of the connecting shaft are respectively connected to the first mounting portion and the hook.
[0009] In one embodiment, the first mounting part and the connecting shaft are provided with opposing strip holes, and a connecting pin is provided in the strip hole.
[0010] In one embodiment, the housing has a groove that adapts to the shape of the hook.
[0011] In one embodiment, both the groove and the hook are arc-shaped.
[0012] In this invention, an infusion monitor with a pressure sensor drop protection structure includes a housing with a hanging ring, a sensor unit disposed inside the housing, a buffer unit, and a hook located outside the housing. The sensor is connected to the hanging ring, and the hook and the sensor unit are connected via the buffer unit. The hook has a buffer gap with the housing when no external force is applied. Therefore, in this invention, when the infusion monitor falls to the ground, the hook hits the ground and experiences upward pressure. The buffer unit cushions this pressure, and simultaneously, the hook contacts the housing, transferring the rebound force from the ground onto the housing to relieve the force, thus protecting the internal sensor unit from external force.

[0025] This invention provides an infusion monitor with a pressure sensor drop protection structure.
[0026] like Figure 1-5As shown, the infusion monitor with a pressure sensor anti-drop protection structure provided in this embodiment of the present invention includes a housing 10 with a hanging ring 20, a sensor unit 30 disposed inside the housing 10, a buffer unit 40, and a hook 50 located outside the housing 10. The sensor is connected to the hanging ring 20, and the hook 50 is connected to the sensor unit 30 through the buffer unit 40. The hook 50 has a buffer gap 60 between itself and the housing 10 when no external force is applied.
[0027] In this embodiment, when the infusion monitor falls to the ground, the hook 50 touches the ground and is subjected to upward pressure. At this time, the pressure can be buffered by the buffer unit 40. At the same time, the hook 50 will contact the outer shell 10, and the rebound force of the hook 50 on the ground will be transferred to the outer shell 10 to relieve the force, thereby protecting the internal sensor unit 30 from external forces.
[0028] The outer casing 10 has a groove that matches the shape of the hook 50, so that when the hook 50 is subjected to external force, the external force can be effectively transmitted to the outer casing 10. In an optional embodiment, both the groove and the hook 50 are arc-shaped.
[0029] Please refer to Figure 3-4 The buffer unit 40 includes a hook connector, and the sensor unit 30 is fixedly mounted on the hook connector. The buffer unit 40 also includes a buffer compression spring 43 disposed within the hook connector. In this embodiment, the buffer compression spring 43 can buffer external forces and prevent them from acting directly on the sensor unit 30.
[0030] Specifically, the hook connector includes a first mounting portion 41 and a second mounting portion 42. The first mounting portion 41 has a cavity for accommodating the second mounting portion 42. The buffer compression spring 43 is disposed in the cavity and abuts against the opposite sides of the first mounting portion 41 and the second mounting portion 42. The second mounting portion 42 passes through the bottom of the outer casing 10 and connects to the hook 50. In this embodiment, the first mounting portion 41 and the second mounting portion 42 are provided with strip-shaped holes 45, and the two can be connected by a connecting pin 44 passing through the strip-shaped holes 45 on the first mounting portion 41 and the second mounting portion 42.
[0031] When the hook 50 moves upward under external force, the connecting pin 44 can move up and down within the slot 45 under the action of external force, thereby providing cushioning.
[0032] For details, please refer to Figure 4The second mounting portion 42 includes a connecting shaft 421 and abutment portions 422 protruding outward from both sides of the connecting shaft 421. The two ends of the buffer compression spring 43 are respectively connected to the abutment portions 422 and the first mounting portion 41. The two ends of the connecting shaft 421 are respectively connected to the first mounting portion 41 and the hook 50. In this embodiment, the strip-shaped hole 45 is opened on the upper part of the connecting shaft 421, and the lower part of the connecting shaft 421 is connected to the hook 50. Therefore, when the hook 50 is subjected to external force, the external force is first transmitted to the abutment portion 422 through the hook 50 itself, and then transmitted to the buffer compression spring 43 for buffering. At this time, the hook 50 moves upward and contacts the groove on the outer casing 10, simultaneously transmitting part of the external force to the outer casing 10 for stress relief. Through these two buffering and stress relief methods, the impact force is prevented from being transmitted to the sensor unit 30, thus providing protection.
[0033] It is understood that this application does not improve the specific principle of how the sensor unit 30 monitors the infusion, and the above-mentioned principles, circuit connection methods and signal communication methods are all existing technologies and can be directly adopted. Therefore, this application will not elaborate on them.
[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
