Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more particularly to a device for testing an insulin needle. Background Art

[0002] With the continuous increase in the number of diabetic patients, the domestic demand for medical devices used to regulate blood sugar with insulin is also increasing. Insulin needles have been generally accepted by the domestic market as disposable consumables, and the number of registered domestic companies for this product is also increasing. At present, most insulin needles in the domestic market do not test the flow rate during the factory inspection of products, but use the method of testing the inner diameter of the needle tube instead. With the popularization of the product, the corresponding industry standards are also being drafted. The domestic industry standards planned to be drafted in 2019 have already set requirements for flow rate, so the domestic standards need to compulsorily test this item. In addition, some other project tests are also stipulated.

[0003] However, the current related testing devices have some shortcomings, such as inconvenient operation, single test items, etc. Therefore, a new powder forming technology is needed to at least partially eliminate the above problems existing in the prior art. Summary of the invention

[0004] In order to at least partially solve the above-mentioned problems existing in the prior art, the present invention provides a device for testing an insulin needle, characterized in that it comprises a connector (10), an extension portion (20) and a sealing portion (30), wherein the connector comprises a threaded portion (11) with threads formed on the surface and a non-threaded portion (12), the extension portion (20) extends from the non-threaded portion (12) and has an outer diameter smaller than the outer diameter of the connector (10), the sealing portion (30) is arranged on the end surface of the threaded portion (11), and a cavity (40) is formed inside the connector (10) and the extension portion (20).

[0005] According to an embodiment of the present invention, the sealing portion (30) is a sealing ring.

[0006] According to an embodiment of the present invention, the sealing ring is made of silicone.

[0007] According to an embodiment of the present invention, the length of the extension portion (20) is greater than the length of the joint (10).

[0008] According to an embodiment of the present invention, the inner diameter of the portion of the cavity (40) in the joint (10) is greater than the inner diameter of the portion in the extension (20).

[0009] According to an embodiment of the present invention, the length of the non-threaded portion (12) is not less than the length of the threaded portion (11).

[0010] Compared with the prior art, the device of the present invention is provided with a longer non-threaded portion, which is convenient for the inspector to operate. In addition to being able to detect needle tip jump, the device of the present invention can also detect product flow, disassembly and installation torque, and firmness. In addition, the overall design of the device of the present invention makes the device practical and reduces the detection error caused by repeated replacement of the test device.

[0016] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0017] Figure 1 A schematic diagram of the structure of a device for testing an insulin needle according to one embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram of another angle of the device for testing insulin needles shown; Figure 3 FIG. 1 is an exploded schematic diagram of a device for testing an insulin needle according to one embodiment of the present invention. Figure 1-3 The device for testing an insulin needle of the present invention may include a connector (10), an extension portion (20) and a sealing portion (30), wherein the connector includes a threaded portion (11) having threads formed on the surface thereof and a non-threaded portion (12), the extension portion (20) extending from the non-threaded portion (12) and having an outer diameter smaller than the outer diameter of the connector (10), the sealing portion (30) being arranged on the end surface of the threaded portion (11), and a cavity (40) being formed inside the connector (10) and the extension portion (20).

[0018] More specifically, with reference to the accompanying drawings, the device of the present invention includes a connector 10, which is substantially a hollow cylinder, with threads formed on a portion of the surface (constituting a threaded portion 11) for connection and fixation with an insulin needle. No threads are formed on the surface of another portion, thereby constituting a non-threaded portion 12. The length of the non-threaded portion is not less than the length of the threaded portion, so that the operation of the device can be facilitated, for example, it is convenient to manually test the beating of the needle tip.

[0019] Extending further along the non-threaded portion 12 is the extension portion 20. The outer diameter of the extension portion 20 becomes smaller, thereby becoming more slender, and its length is greater than the length of the connector 10, and a cavity (channel) is also formed in the center. The connector 10 and the extension portion 20 can be integrally formed, and a cavity 40, i.e., a central channel, is formed in the middle, wherein the inner diameter of the cavity in the connector 10 is greater than the inner diameter of the cavity in the extension portion 20. The extension portion 20 with a reduced outer diameter is convenient for connecting other pipelines.

[0020] In addition, the device of the present invention also includes a sealing portion 30, which is arranged on the end face of the side where the threaded portion 11 of the connector 10 is located. The sealing portion can be, for example, a sealing ring made of medical-grade silicone. The sealing ring should fit tightly with the connector and should not fall off in the reverse direction after being installed. The sealing ring can protrude from the connector end face by a certain thickness, for example, it can be greater than 0.3 mm, to facilitate subsequent sealing. The purpose of adding a sealing ring to the connector end face is to prevent leakage and facilitate flow testing. In addition, the diameter reduction of the rear half of the device is to facilitate the connection, installation, and disassembly of the pipeline, torque detection, and needle tube firmness detection, and the internal through hole is to facilitate the passage of the test liquid.

[0021] The working principle of the device of the present invention is as follows: the sealing ring is installed on the joint, connected to the insulin needle through a V-block to detect the needle tip jump, the product flow is detected by connecting the insulin needle and the catheter, and the firmness and torque are detected by clamping the tail of the joint and the plastic part of the needle.

[0022] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0023] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0024] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
