Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical devices, and particularly relates to a tool for assisting the assembly of the shell of a pulse oximeter. Background Art
[0002] A wrist-type pulse oximeter is a monitor worn on the wrist for hospitals and families to monitor the pulse oxygen saturation and pulse rate of patients. The wrist-type design is convenient to wear and prevent falling off, and can continuously measure. When assembling the pulse oximeter, the watch case and the watch band are placed on the operating table. Since the watch case and the watch band are integrated and the watch band made of silicone material has certain elasticity, the watch case cannot be naturally placed flat on the operating table surface. When assembling, one hand needs to hold the watch case, and the other hand performs the assembly operation. The single-hand assembly has low efficiency and slow progress; or two people are required to operate, one presses the watch case, and the other assembles. This assembly method increases the production cost. Summary of the Utility Model

The substrate is provided with an anti-deformation protrusion for placing the watch case. Fixing buckles for fixing the watch band are respectively arranged on the left and right sides of the protrusion. Limiting plates higher than the protrusion are respectively arranged on the front and back sides of the protrusion. The two limiting plates and the top of the protrusion form a groove for placing the watch case.
[0005] Further, the protrusion is strip-shaped, the protrusion is a hollow body or a solid body, the top end of the protrusion is a plane for stably placing the watch case, and the surface between the top end of the protrusion and the upper surface of the substrate is a smoothly transitioned curved surface, which conforms to the natural bending state of the watch band.
[0006] Further, the fixing buckle is in a shape of "匚", the opening of the fixing buckle faces the upper surface of the substrate, and comprises two parallel supporting parts vertically connected to the substrate and a horizontal connecting part fixed above the supporting parts.
[0007] Further, a positioning through hole for the watch band to pass through is formed by enclosing the supporting part, the horizontal connecting part and the upper surface of the substrate. The positioning through hole is a flat square hole, and the height of the positioning through hole is slightly larger than the thickness of the watch band, for example, 3-5 mm larger, so that the watch band can pass through smoothly.
[0008] Further, a vertical threaded hole is formed in the horizontal connecting part, a threaded rod is connected in the threaded hole, a gasket is arranged at one end of the threaded rod extending into the positioning through hole, and the end of the threaded rod far away from the gasket is a dome convenient for rotation or a short rod vertically connected to the threaded rod. The gasket can be circular, for example. When the watch band passes through the positioning through hole, the threaded rod is rotated towards the direction close to the watch band until the gasket presses the watch band tightly.
[0009] Furthermore, the top of the limiting plate is higher than the top plane of the protrusion, the distance of the higher position is greater than the thickness of the watch case, the length direction of the limiting plate is consistent with the direction in which the curved surface of the protrusion extends forward and backward, and the limiting plate is fitly connected to the front and rear sides of the protrusion.
[0010] Furthermore, the substrate is in any shape such as a rectangular plate, a square plate, or a circular plate, and can be stably placed on the operating platform.
[0011] Furthermore, the entire tooling is made of resin material to avoid scratching the case and can be reused many times.
[0012] When the tooling for auxiliary assembly of the pulse oximeter shell of the utility model is used, it is first placed on an operating platform, and then the watch case is placed in a groove formed by a limiting plate and the top of a protrusion, and the strap connected with the watch case is naturally extended along the curved surface of the protrusion, passes through the positioning through hole, and the threaded rod is rotated in a direction close to the watch band until the gasket presses the watch band, and the watch case and the watch band are fixed on the protrusion. The operator assembles it, and after the assembly is completed, the threaded rod is rotated in a direction away from the watch band, the watch is removed, and the next watch case is replaced to continue the operation.

[0020] As Figure 1 shown, a tool for assisting the assembly of the shell of a pulse oximeter according to the present utility model includes a substrate 1 placed on an operation platform. The substrate 1 is provided with an anti - deformation protrusion 2 for placing the watch case. Fixing buckles 3 for fixing the watch band are respectively arranged on the left and right sides of the protrusion 2, and limiting plates 4 higher than the protrusion 2 are respectively arranged on the front and rear sides of the protrusion 2. The two limiting plates 4 and the top of the protrusion 2 form a groove 5 for placing the watch case.
[0021] The protrusion 2 is strip - shaped, and the protrusion 2 is a hollow body or a solid body. The top end of the protrusion 2 is a plane for stably placing the watch case. A smooth - transition curved surface 21 is formed between the top end of the protrusion 2 and the upper surface of the substrate 1 to fit the natural bending state of the watch band.
[0022] The fixing buckle 3 is in a U - shape, and the opening of the fixing buckle 3 faces the upper surface of the substrate 1. It includes two parallel support parts 31 vertically connected to the substrate 1 and a horizontal connection part 32 fixing above the support parts 31.
[0023] The support part 31, the horizontal connection part 32 and the upper surface of the substrate 1 enclose a positioning through - hole 6 for the watch band to pass through. The positioning through - hole 6 is a flat square hole, and the height of the positioning through - hole 6 is slightly larger than the thickness of the watch band, for example, 3 - 5 mm larger, so that the watch band can pass through smoothly.
[0024] A vertical threaded hole is opened on the horizontal connection part 32. A threaded rod is connected in the threaded hole. A gasket is arranged at one end of the threaded rod extending into the positioning through - hole 6. The end of the threaded rod away from the gasket is a dome for convenient rotation or a short rod perpendicularly connected to the threaded rod. The gasket can be circular, for example. When the watch band passes through the positioning through - hole 6, rotate the threaded rod towards the direction close to the watch band until the gasket presses the watch band tightly.
[0025] The top end of the limiting plate 4 is higher than the top plane of the protrusion 2, and the height difference is larger than the thickness of the watch case. The length direction of the limiting plate 4 is consistent with the front - rear extension direction of the curved surface of the protrusion 2, and the limiting plate 4 is in a fitting connection with the front side surface 22 and the rear side surface 23 of the protrusion 2.
