Description

Technical Field

[0001] This utility model belongs to the field of medical devices, specifically relating to a skin test result detection device. Background Technology

[0002] In clinical skin testing, healthcare professionals typically use ordinary rulers or gauges to measure skin reactions (such as redness, swelling, and induration) at the test site. However, visual methods are prone to significant subjective errors. While existing measuring instruments, such as the tuberculin skin test result calipers disclosed in patent CN202223329014.7, can measure the length and width of indurations, they still cannot effectively address the challenge of measuring the curved surfaces of the limbs. Because the limb surface is curved, traditional rulers or flat measuring tools cannot closely conform to the skin, leading to inaccurate measurement data. Furthermore, they require both hands to operate, making clinical use inconvenient. Therefore, existing technologies suffer from the problem of measuring tools failing to adapt to limb curvature, resulting in insufficient measurement accuracy. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a skin test result detection device, which solves the problem that the measuring tool in the existing technology cannot adapt to the curvature of the limb, resulting in insufficient measurement accuracy.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A skin test result detection device includes a housing;

[0006] A take-up roller is rotatably connected to the housing;

[0007] A measuring tape is wound around the periphery of the take-up roller. One end of the measuring tape is fixed to the periphery of the take-up roller, and the other end of the measuring tape is fixed to a lifting roller that is placed coaxially with the take-up roller.

[0008] The measuring band is made of a transparent, flexible material and has a first and second scale line that are perpendicular to each other.

[0009] The first scale line is arranged along the direction of the measurement zone;

[0010] There are multiple second scale lines, all of which are placed coaxially with the lifting roller, and the multiple second scale lines are evenly distributed along the extension direction of the first scale line.

[0011] The housing is provided with a locking part, which is used to lock or release the rotation of the take-up roller;

[0012] The housing has a pair of storage slots for holding the lifting roller. The two storage slots are symmetrically arranged about the winding roller, and both storage slots are placed in the same direction as the winding roller.

[0013] Both the storage slot and the lifting roller can be detachably connected;

[0014] One end of the take-up roller passes through the housing and is fixedly connected to a knob placed on the same axis;

[0015] The knob near the end of the take-up roller forms a limiting flange with a diameter larger than that of the take-up roller;

[0016] The locking part includes a sleeve disposed between the knob and the housing. The sleeve and the take-up roller are placed on the same axis. The end of the sleeve away from the knob is open. The take-up roller slides through the sleeve. A ring block is fixed to the housing near the end of the sleeve. The ring block and the sleeve are placed on the same axis. The ring block has an external thread on its peripheral wall. The sleeve has a matching internal thread inside.

[0017] When the sleeve is rotated and approaches the knob, the sleeve abuts against the knob's limiting flange;

[0018] A ring-shaped rubber pad is fixed to one end of the sleeve near the knob;

[0019] The lifting roller is made of ferromagnetic material. A through groove is opened on the shell to pass through the two storage slots. A magnet is fixed in the through groove, and the two ends of the magnet are flush with the peripheral walls of the two storage slots.

[0020] Multiple anti-slip strips are provided on the peripheral wall of the sleeve.

[0021] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0022] Fixed connection: refers to a connection method in which two or more components are tightly connected together by welding, gluing or other methods, and cannot be easily separated.

[0023] Rotary connection: refers to a connection where two parts can rotate relative to each other, and is often used in mechanical devices when rotational motion is required.

[0024] The beneficial effects of this utility model are:

[0025] 1. Place the housing on the periphery of the limb away from the skin test site, then release the locking part from the take-up roller; pull the lifting roller, which will cause the measuring tape to wrap around the limb once. Then, hold the housing and lifting roller with one hand and rotate the take-up roller to tighten the loose measuring tape, so that the measuring tape near the skin test site is in close contact with the limb skin. This solves the problem in the prior art that the measuring tool cannot adapt to the curvature of the limb. The longitudinal diameter of the skin test reaction is measured through the first scale line, and the transverse width is measured through the evenly distributed second scale line, realizing bidirectional accurate measurement and improving the measurement accuracy of the skin test results of the curved surface of the limb.

[0026] At the same time, when reading and recording the first and second scale lines, the rotation of the take-up roller can be locked by the locking part to prevent the take-up roller from rotating accidentally and causing the measuring belt to loosen, thus ensuring the accuracy of the measurement results;

[0027] 2. By combining the storage groove, lifting roller, and magnet, the problem of difficulty in holding the housing and lifting roller with one hand is solved, effectively improving the stability when holding the housing and lifting roller with one hand and avoiding relative sliding between the lifting roller and the housing, which would affect the accuracy of the measurement results;

[0028] 3. The combination of knobs, sleeves, ring blocks, and rubber pads facilitates the control of locking or releasing the rotation of the take-up roller. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] This combination Figures 1 to 4This describes an embodiment of a skin test result detection device. Specifically, the skin test result detection device is constructed as a split structure, comprising a housing 100, a take-up roller 200, a measuring belt 300, a lifting roller 400, a first scale line 501, a second scale line 502, and a locking part 600. Pulling the lifting roller 400 causes the measuring belt 300 to wrap around the limb once. Then, holding the housing 100 and the lifting roller 400 with one hand and rotating the take-up roller 200 tightens the loose measuring belt 300, making the measuring belt 300 near the skin test site fit tightly against the limb skin. This solves the problem in the prior art where the measuring tool cannot adapt to the curvature of the limb. Furthermore, the longitudinal diameter of the skin test reaction is measured by the first scale line 501, and the lateral width is measured by the evenly distributed second scale line 502, achieving bidirectional accurate measurement and improving the measurement accuracy of skin test results on the curved surface of the limb.

[0036] Please refer to Figures 1 to 4 A skin test result detection device, comprising a housing 100;

[0037] A take-up roller 200 is rotatably connected to the housing 100;

[0038] A measuring belt 300 is wound around the periphery of the take-up roller 200. One end of the measuring belt 300 is fixed to the periphery of the take-up roller 200, and the other end of the measuring belt 300 is fixed to a lifting roller 400 that is placed coaxially with the take-up roller 200.

[0039] The measuring band 300 is made of a transparent flexible material and has a first scale line 501 and a second scale line 502 that are perpendicular to each other.

[0040] The first graduation line 501 is arranged along the extension direction of the measuring band 300;

[0041] There are multiple second scale lines 502, all of which are placed coaxially with the lifting roller 400, and the multiple second scale lines 502 are evenly distributed along the extension direction of the first scale line 501.

[0042] The housing 100 is provided with a locking part 600, which is used to lock or release the rotation of the take-up roller 200;

[0043] In use, place the housing 100 on the side opposite the skin test site on the limb periphery, then release the locking part 600 from locking the take-up roller 200; pull the lifting roller 400, which drives the measuring band 300 to wrap around the limb once; then hold the housing 100 and the lifting roller 400 with one hand, and rotate the take-up roller 200 to tighten the loose measuring band 300, so that the measuring band 300 near the skin test site is in close contact with the limb skin; measure the longitudinal diameter of the skin test reaction through the first scale line 501, and measure the transverse width through the evenly distributed second scale line 502, to achieve bidirectional accurate measurement and improve the measurement accuracy of the skin test results for the curved surface of the limb;

[0044] At the same time, when reading and recording the first scale line 501 and the second scale line 502, the rotation of the take-up roller 200 can be locked by the locking part 600 to prevent the take-up roller 200 from rotating accidentally and causing the measuring belt 300 to loosen, thus ensuring the accuracy of the measurement results.

[0045] When not in use, the take-up roller 200 is rotated to wind up the measuring tape 300. After winding, the take-up roller 200 is locked by the locking part 600 to ensure that the measuring tape 300 remains neatly wound.

[0046] Preferably, the measuring band 300 is made of a medical-grade thermoplastic polyurethane (TPU) film with a thickness of 0.1-0.3mm, a light transmittance of ≥90%, and a tensile strength of ≥20MPa. The medical-grade thermoplastic polyurethane film not only has high transparency but also high flexibility, which can ensure that there is no visual obstruction in the skin test reaction area, and can wrap around the limb 360° without creases.

[0047] The housing 100 has a pair of storage slots 101 for placing the lifting roller 400. The two storage slots 101 are symmetrically arranged about the winding roller 200, and the storage slots 101 are placed in the same axis as the winding roller 200.

[0048] During measurement, after the measuring band 300 is wrapped around the patient's limb once, the lifting roller 400 can be placed in one of the storage slots 101. The storage slot 101 solves the problem of difficulty in holding the housing 100 and the lifting roller 400 with one hand, effectively improving the stability when holding the housing 100 and the lifting roller 400 with one hand, and avoiding relative sliding between the lifting roller 400 and the housing 100, which would affect the accuracy of the measurement results.

[0049] Both the storage slot 101 and the lifting roller 400 can be detachably connected;

[0050] When in use, after the lifting roller 400 drives the measuring belt 300 to wrap around the limb once, the lifting roller 400 can be detachably connected to a storage groove 101 to improve the stability of the connection between the housing 100 and the storage groove 101.

[0051] When not in use, after the measuring tape 300 is wound up, the lifting roller 400 is detachably connected to the storage slot 101. With the locking part locking the winding roller 200, the measuring tape 300 can be prevented from accidentally coming loose or coming apart during storage or carrying, keeping the device neat and orderly.

[0052] One end of the take-up roller 200 passes through the housing 100 and is fixedly connected to a knob 201 placed on the same axis; after the measuring belt 300 is wrapped around the limb once, the knob 201 is turned to drive the take-up roller 200 to rotate, so as to tighten the loose measuring belt 300.

[0053] A limiting flange with a diameter larger than that of the take-up roller 200 is formed near the end of the knob 201 near the take-up roller 200;

[0054] The locking part 600 includes a sleeve 601 disposed between the knob 201 and the housing 100. The sleeve 601 and the take-up roller 200 are placed on the same axis. The end of the sleeve 601 away from the knob 201 is open. The take-up roller 200 slides through the sleeve 601. A ring block 602 is fixed to the end of the housing 100 near the sleeve 601. The ring block 602 and the sleeve 601 are placed on the same axis. The ring block 602 has an external thread 6021 on its peripheral wall. The sleeve 601 has a matching internal thread inside.

[0055] When the rotating sleeve 601 moves closer to the knob 201, the sleeve 601 abuts against the limiting flange of the knob 201;

[0056] When it is necessary to release or rewind the measuring tape 300, rotate the sleeve 601 to move the sleeve 601 away from the knob 201. At this time, the knob 201 and the take-up roller 200 can rotate freely. When it is necessary to limit and lock the rotation of the take-up roller 200, rotate the sleeve 601 in the other direction to bring the sleeve 601 close to the knob 201 until one end of the sleeve 601 is pressed into contact with the limiting flange of the knob 201, thereby locking the rotation of the knob 201 and the take-up roller 200.

[0057] An annular rubber pad 603 is fixed to one end of the sleeve 601 near the knob 201; preferably, the rubber pad 603 is made of silicone or rubber material; when the drive sleeve 601 approaches the knob 201, the rubber pad 603 abuts against the limiting flange of the knob 201, and the elastic deformation of the rubber pad 603 increases the friction between it and the limiting flange of the knob 201, thereby improving the stability of locking the knob 201 and the take-up roller 200.

[0058] The lifting roller 400 is made of ferromagnetic material. The housing 100 has a through groove 102 that passes through the two storage slots 101. A magnet 700 is fixed in the through groove 102. The two ends of the magnet 700 are flush with the peripheral walls of the two storage slots 101. The magnet 700 is magnetically attracted to the lifting roller 400, which facilitates the detachable connection between the lifting roller 400 and the storage slot 101, making it convenient to take out or store the lifting roller 400.

[0059] Multiple anti-slip strips 6011 are provided on the peripheral wall of the sleeve 601; the anti-slip strips 6011 are provided to facilitate the rotation of the sleeve 601 for threaded transmission.
