Description
Technical Field
[0001] The utility model relates to medical glue, in particular to a medical glue adhesion detection device. Background Art
[0002] Medical adhesive is an adhesive designed for medical use. It not only has the bonding properties of conventional adhesives, but also must meet strict requirements such as biocompatibility, non-toxicity, and non-irritation to ensure safety and effectiveness in medical applications inside or outside the human body. For example, the prevention and treatment of soft tissue or skin adhesion are all involved. Before the adhesive is produced, it is generally tested whether the adhesion meets the medical standards. If it does not meet the standards, it is considered unqualified, and the unqualified adhesive is prepared again until it passes the test. The existing adhesive adhesion testing equipment usually applies the adhesive on two transmission structure planes, fixes one transmission mechanism, and uses another transmission mechanism to pull to test the adhesion of the adhesive. However, during the testing process, this method is unstable because the adhesive is attached to one of the transmission structures. During the pulling process, the adhesive is separated from the plane of the transmission mechanism due to unstable adhesion, resulting in a large error between the result of the adhesion test of the testing equipment and the actual adhesion. Therefore, it is urgent to design a medical adhesive adhesion testing device with the ability to test the actual adhesion of the adhesive to solve the above problems. Utility Model Content

DETAILED DESCRIPTION
[0025] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.
[0026] Example 1
[0027] See also Figures 1 to 4 The utility model provides a medical glue adhesion detection device, including a working platform 1, a square groove 2 is provided on the upper part of the working platform 1, a support seat 3 is provided on the bottom surface of the square groove 2, and a mutually symmetrical support plate 4 is provided on the top surface of the support seat 3, a rotating wheel 5 is rotatably connected between the support plates 4, a driving component 6 is provided on the side of the support plate 4, and the output of the driving component 6 passes through the support plate 4 and is connected to the rotating wheel 5; a fixing piece 7 is provided on the top surface of the square groove 2, a dynamometer 8 is built in the fixing piece 7, a skin-like block 9 is connected to the pulling end of the dynamometer 8, and the skin-like block 9 is movably connected in the fixing piece 7, a heating element 10 is provided behind the fixing piece 7, the heating element 10 is hinged to the skin-like block 9 through a heating strip 11, and the heating element 10 is controlled by a temperature control unit 12 arranged on the top surface of the working platform 1; a connecting strip 13 is provided on the outer peripheral surface of the rotating wheel 5, and a clamping piece is provided at the end of the connecting strip 13, and the clamping piece is connected to the skin-like block 9 by clamping the medical glue.
[0028] The support seat 3 is in the shape of a terrace, and its bottom surface is fixedly connected to the top surface of the square groove 2. The support seat 3 has good stability in use. A DFG-RS3 type dynamometer 8, which is conventionally sold in the market, is provided in the fixing member 7. The pulling end of the dynamometer 8 is used to flexibly connect the skin-like block 9. When the medical glue is attached to the skin-like block 9, the pulling end of the dynamometer 8 is driven by pulling the skin-like block 9 to complete the tension test, and further determine the adhesion test of the medical glue. The skin-like block 9 is heated by the heating element 10 to simulate the temperature of the skin on the body surface, which is conducive to the accuracy and practicality of detecting the adhesion of the medical glue. The heating element 10 is continuously controlled by the temperature control unit 12 so that the heating element 10 maintains a suitable temperature. The temperature control unit 12 adopts a digital temperature control instrument. By setting the digital temperature control instrument, the user can preset the target temperature. The instrument is connected to a temperature sensor, which monitors the actual temperature and compares it with the set value. When the actual temperature is lower than the set value, the relay contacts of the instrument are closed, and the power is turned on to the electric heating element 10 to start heating. When the temperature reaches the standard, the contacts are disconnected and heating stops, thus achieving the effect of keeping the temperature constant for a long time.
[0029] Specifically, before the medical glue contacts the skin-like block 9, the heat is transferred to the heating strip 11 through the heating element 10, and the heating strip 11 heats the skin-like to the temperature of the human body surface skin. When the temperature is suitable, the heating element 10 is controlled by the temperature control unit 12 to maintain the suitable temperature. Subsequently, the medical glue is clamped by a clamp, and then the connecting strip 13 is pulled to extend upward, while driving the rotating wheel 5 to rotate. The medical glue is pasted to the skin-like block 9, and the rotating wheel 5 is slowly driven by the driving component 6. The rotating wheel 5 drives the connecting strip 13 to be wound until the medical glue falls on the side of the skin-like block 9, and the maximum adhesion of the medical glue is recorded by the dynamometer 8. The heating element 10 is used to heat the skin-like block 9 to achieve an effect similar to human skin, so that the detection process is closer to the use of medical glue on the human body. Therefore, the adhesion detection of the medical glue is more accurate and the error is reduced. The utility model solves the technical problem that the results of the adhesion test of the existing equipment detection equipment have a large error with the actual adhesion.
[0030] Furthermore, the driving component 6 is a driving motor or a rotating rod.
[0031] A driving motor or a rotating rod is used to provide driving force. When a driving motor is used, a driving motor with a slower rotation speed is required to facilitate accurate detection of the adhesion of the medical glue. The rotating rod can be slowly rotated by manpower, which is conducive to accurate detection of the adhesion of the medical glue.
[0032] Furthermore, the heating element 10 includes a heating body, which is hinged to one end of a heating strip 11, and the other end of the heating strip 11 is hinged to the skin-like block 9; the heating body is connected to a temperature control unit 12.
[0033] The heating element is made of a resistance wire with high resistivity. When current passes through, it generates heat according to Joule's law, realizing the conversion of electrical energy into thermal energy. After the heating element generates thermal energy, it transfers the heat to the heating strip 11, and the heating strip 11 transfers the heat to the skin-like block 9, so that the skin-like block 9 generates a suitable temperature for subsequent detection.
[0034] Furthermore, the skin-like block 9 includes a substrate 92 and a skin-like membrane 91 , the skin-like membrane 91 is nailed to one side of the substrate 92 , and the other side of the substrate 92 is hinged to the end of the heating strip 11 .
[0035] The skin-like film 91 is a surface treatment material or film with a touch similar to human skin, which improves the practicality of medical glue detection. It is fixed on the side of the base plate 92 by nails. During the pulling process of the medical glue detection, when the base plate 92 is pulled downward, the heating strip 11 swings downward with it through the hinge action, and the temperature will not be affected in this process.
[0036] Furthermore, the fixing member 7 has a through slot 24 built therein, a skin-like block 9 and a dynamometer 8 are arranged in the through slot 24 , and a display screen of the dynamometer 8 is arranged at an upper portion of the through slot 24 .
[0037] The through groove 24 is convenient for the medical adhesive to stick the skin-like block 9. At the same time, the display numbers of the dynamometer 8 can be clearly seen, so that the user can intuitively see the detected pulling force.
[0038] In this embodiment, the clamping member includes a first clamping block 14 and a second clamping block 15 . The bottom ends of the first clamping block 14 and the second clamping block 15 are hinged to each other, and the lower parts of the first clamping block 14 and the second clamping block 15 are connected by a connecting part.
[0039] Furthermore, the connecting portion includes a first extending rod 16 provided on a side of the first clamping block 14 , and a second extending rod 17 provided on a side of the second clamping block 15 . The first extending rod 16 and the second extending rod 17 are connected via a first spring 18 .
[0040] In one example, the first clamping block 14 and the second clamping block 15 are manually separated from each other at the top, and their bottoms are hinged and rotated with each other, and at the same time, the first extension rod 16 and the second extension rod 17 pull the first spring 18 apart to improve stability. After the tops of the first clamping block 14 and the second clamping block 15 are opened, the clamped medical glue is placed into the opening, and then the elastic potential energy of the first spring 18 is released, and the first extension rod 16 and the second extension rod 17 are relatively close to each other, driving the first clamping block 14 and the second clamping block 15 to tightly clamp the medical glue, which is convenient for the subsequent stable adhesion test of the medical glue.
[0041] Example 2
[0042] See also Figure 1-Figure 3 and Figure 5As another preferred embodiment, the connecting portion includes a first arc block 19 provided on the side of the first clamping block 14, and a second arc block 20 provided on the side of the second clamping block 15. The first arc block 19 and the second arc block 20 are in cross contact, and the bottom opposite surfaces of the first arc block 19 and the second arc block 20 are connected by a second spring 21.
[0043] In one example, the first clamping block 14 and the second clamping block 15 are manually separated from each other at the top, and their bottoms are hinged and rotated with each other. At the same time, the first arc block 19 and the second arc block 20 are frictionally moved relative to each other and the second spring 21 is pulled apart. After the tops of the first clamping block 14 and the second clamping block 15 are opened, the medical glue is placed into the opening, and then the elastic potential energy of the second spring 21 is released. The first arc block 19 and the second arc block 20 are frictionally moved relative to each other, driving the first clamping block 14 and the second clamping block 15 to tightly clamp the medical glue, which is convenient for subsequent stable adhesion testing of the medical glue.
[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
