Description

Technical Field

[0001] This utility model relates to the field of protective shell technology for blood pressure monitors, and in particular to a shell structure for a non-contact heart rate and blood pressure monitor. Background Technology

[0002] In recent years, non-contact heart rate and blood pressure measurement technology has gradually become a research hotspot in the field of health monitoring due to its advantages such as non-invasiveness, convenience, and hygiene. This technology is mainly based on IPPG (imaging photoplethysmography) and video micro-magnification technology. It remotely captures changes in micro-blood flow in the human face or torso through optical sensors (such as cameras and infrared modules), and calculates heart rate and blood pressure by combining algorithms. Compared with traditional contact devices (such as cuff blood pressure monitors and electrode patches), non-contact solutions avoid the discomfort caused by skin contact and reduce the risk of cross-infection, making them suitable for daily health monitoring and medical scenarios.

[0003] In existing technologies, non-contact heart rate and blood pressure monitors are comparable in effectiveness to contact heart rate and blood pressure monitors, making them widely applicable in health monitoring or medical institutions. Typically, the instrument is placed on a table, with the patient looking at the detection lens of the non-contact heart rate and blood pressure monitor. However, traditional housings are not easy to disassemble and install. When the internal equipment needs maintenance or replacement, it requires forced disassembly. Therefore, there is an urgent need to design a housing structure for non-contact heart rate and blood pressure monitors. Utility Model Content

[0004] The purpose of this invention is to solve the problem that traditional housings in the prior art are inconvenient to disassemble and require forced removal, and to propose a housing structure for a non-contact heart rate and blood pressure measuring instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A housing structure for a non-contact heart rate and blood pressure monitor includes an outer shell with an opening at one end, and further includes: a bottom frame plate detachably connected to the opening end of the outer shell via a snap-fit ​​assembly, wherein the bottom frame plate is C-shaped and its outer wall fits against the outer shell; and a top frame plate detachably connected to the outer wall of the outer shell, wherein the bottom frame plate has axially extending snap-fit ​​grooves on its two end side walls, and the bottom of the top frame plate has snap-fit ​​plates at both ends, which snap into the snap-fit ​​grooves, and the bottom end of the top frame plate abuts against the top surfaces of the two ends of the bottom frame plate.

[0007] To facilitate the fixed connection of the bottom frame plate to the outer shell, preferably, the snap-fit ​​assembly includes an extension plate fixedly connected to the outer shell, and a limiting groove is formed on the side plate of the bottom frame plate, and the extension plate is snap-fitted into the limiting groove.

[0008] To further improve the limiting effect of the outer shell, a connecting groove is provided on the bottom plate of the bottom frame plate, and the outer shell is connected to the connecting groove by a connecting plate.

[0009] To facilitate easy disassembly of the locking plate, preferably, an expansion groove is provided in the locking groove, an expansion plate is fixedly connected to the end of the locking plate, a protrusion is fixedly connected to the expansion plate, a through hole is provided in the expansion groove, the through hole penetrates the bottom frame plate to form an opening, and the protrusion is engaged and connected in the through hole.

[0010] To facilitate the insertion of the protrusion into the perforation, preferably, the cross-section of the protrusion and the perforation is circular.

[0011] In order to enable the camera lens to take pictures, preferably, a light-transmitting hole is provided on the outer wall of the top frame plate.

[0012] To facilitate the covering of the lens when it is not in use, preferably, a sliding groove is provided on the top frame plate, and a baffle is slidably connected to the sliding groove. The baffle is used to block or unblock the light-transmitting hole.

[0013] To facilitate easy movement of the baffle, a protruding plate is further fixedly connected to the outer wall of the baffle.

[0014] To facilitate heat dissipation from the inside of the casing, preferably, heat dissipation holes are provided on the inner wall of the casing.

[0015] Furthermore, the outer shell, bottom frame plate, and top frame plate are made of plastic.

[0016] Compared with the prior art, the present invention provides a housing structure for a non-contact heart rate and blood pressure monitor, which has the following advantages:

[0017] 1. The housing structure of this non-contact heart rate and blood pressure monitor is such that the bottom frame plate is detachably connected to the opening end of the outer shell through a snap-fit ​​assembly. At this time, the outer wall of the bottom frame plate is in contact with the outer shell, thereby forming a semi-enclosed housing structure and achieving a semi-pre-assembled effect.

[0018] 2. The housing structure of this non-contact heart rate and blood pressure measuring instrument is formed by inserting the snap-fit ​​plate at the bottom of the top frame plate into the snap-fit ​​groove, so that the bottom end of the top frame plate abuts against the top surfaces of both ends of the bottom frame plate, thereby forming a fully enclosed housing structure and achieving an overall pre-assembly effect.

[0019] The parts not covered in this device are the same as or can be implemented using existing technology. This utility model can divide the outer shell, bottom frame plate and top frame plate into three components, and then snap the three components together to achieve quick disassembly or installation. While ensuring the protection of the equipment, it can also significantly improve the convenience of maintenance. When the equipment inside the instrument needs maintenance or replacement, there is no need to forcibly disassemble it, thus improving the practicality of the device. Attached Figure Description

[0028] Example:

[0029] Reference Figures 1-5A housing structure for a non-contact heart rate and blood pressure monitor includes a housing 1 with an opening at one end. The non-contact heart rate and blood pressure monitor can be housed inside the housing 1. A heat dissipation hole 103 is also provided inside the housing 1 for heat dissipation of the instrument components inside the housing 1. A bottom frame plate 2 is detachably connected to the opening end of the housing 1 via a snap-fit ​​assembly, allowing the bottom frame plate 2 to be connected to the opening surface of the housing 1. The bottom frame plate 2 is C-shaped, and its outer wall fits snugly against the housing 1. A top frame plate 3 is also detachably connected to the housing 1, allowing the top frame plate 3 to cooperate with the bottom frame plate 2. Axially extending engagement grooves 204 are provided on the side walls at both ends of the bottom frame plate 2. Engaging plates 304 are provided at the bottom of both ends of the top frame plate 3, engaging within the engagement grooves 204. The bottom end of the top frame plate 3 abuts against the top surfaces of both ends of the bottom frame plate 2, allowing the top frame plate 3 and the bottom frame plate 2 to be respectively connected to the housing 1, forming a housing enclosure structure.

[0030] In the above solution, the housing structure of the non-contact heart rate and blood pressure monitor is divided into three independent parts, which can be spliced ​​together to form the entire housing. First, the components of the non-contact heart rate and blood pressure monitor can be placed in the storage slot of the outer shell 1. Then, its bottom frame plate 2 is detachably connected to the opening end of the outer shell 1 through a snap-fit ​​assembly. At this time, the outer wall of the bottom frame plate 2 fits against the outer shell 1, thus forming a semi-enclosed housing structure and achieving a semi-pre-installed effect. Then, the snap-fit ​​plate 304 at the bottom of the top frame plate 3 is inserted into the snap-fit ​​groove 204, so that the bottom end of the top frame plate 3 abuts against the top surfaces of both ends of the bottom frame plate 2, thus forming a fully enclosed housing structure. The above three components can be quickly disassembled or installed through snap-fit, which can significantly improve the convenience of maintenance while ensuring the protection of the equipment. When the equipment inside the instrument needs maintenance or replacement, there is no need to forcibly disassemble it, thus improving the practicality of the device.

[0031] Furthermore, the aforementioned snap-fit ​​assembly includes an extension plate 101 fixedly connected to the outer shell 1, a limiting groove 201 provided on the side plate of the bottom frame plate 2, the extension plate 101 snapping into the limiting groove 201, a connecting groove 202 provided on the bottom plate of the bottom frame plate 2, the outer shell 1 snapping into the connecting groove 202 via the connecting plate 102, thereby enabling pre-connection of the bottom frame plate 2, a limiting hole 203 provided on the outer wall of the side plate of the bottom frame plate 2, and the same limiting hole 203 provided on the extension plate 101, so that the locking screw can be screwed into the limiting hole 203, thereby achieving the fixation between the bottom frame plate 2 and the outer shell 1.

[0032] To facilitate the quick insertion of the top frame plate 3 into the bottom frame plate 2, an expansion groove 205 is provided in the engaging groove 204. An expansion plate 305 is fixedly connected to the end of the engaging plate 304, and a protrusion 306 is fixedly connected to the expansion plate 305. A through hole 206 is provided in the expansion groove 205, which penetrates the bottom frame plate 2 to form an opening. The protrusion 306 engages with the through hole 206. The engaging plate 304 can be inserted into the expansion groove 205 along the engaging groove 204. At this time, the protrusion 306 will extend into the through hole 206, thereby achieving the engaging effect. When it is necessary to disassemble the top frame plate 3, a rod with a diameter smaller than that of the through hole 206 can be used. It should be noted that the cross-section of the protrusion 306 and the through hole 206 is circular. Insert it into the through hole 206 and extend it into the expansion groove 205. At this time, the protrusion 306 can be pressed, and then the engaging plate 304 can be pulled out.

[0033] A light-transmitting hole 301 is provided on the outer wall of the top frame plate 3 to allow light to pass through the camera on the instrument so that it can perform measurement operations. A sliding groove 302 is provided on the top frame plate 3, and a baffle 303 is slidably connected to the sliding groove 302. The baffle 303 is used to block or unblock the light-transmitting hole 301. A protruding plate 307 is fixedly connected to the outer wall of the baffle 303. When it is not needed, the baffle 303 can be pulled by the protruding plate 307 to block the light-transmitting hole 301 and protect the lens.

[0034] It should be explained that the outer shell 1, bottom frame 2, and top frame 3 are made of plastic. PC / ABS composite modified plastic can be used, which has passed biocompatibility certification and meets the standards for medical device contact materials, thereby improving the practicality of the outer shell 1, bottom frame 2, and top frame 3.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
