Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a handheld microneedle using device. Background Art

[0002] Rapid food testing can be used for spot checks on food safety of edible agricultural products, bulk foods, catering foods, and foods prepared and sold on-site, providing quick results. Currently, the main rapid food testing technologies for addressing three major food safety issues: economically motivated meat adulteration and counterfeiting, questionable freshness of fresh foods, and food allergies include chemical colorimetry, biosensors, enzyme-linked immunosorbent assays, and immunocolloidal gold methods. The most effective and accurate methods, such as colloidal gold and electronic nose testing, detect specific DNA fragments from different meat sources. However, these techniques are technically based and require high equipment costs and reagent consumption. They also require cumbersome pretreatment, complex operations, and long testing times. Their specificity is limited, limiting them to detecting a single meat source. Furthermore, they are subject to time and space constraints, making them impractical for on-site, real-time testing. To address these issues, the PVA hydrogel double-layer microneedle patch, with its advantages of low price, compact size, integrated DNA extraction and enrichment, simultaneous detection of multiple adulterated meats, and rapid and accurate analysis of the adulteration status of mixed foods, has become widely used in the food rapid testing industry. However, if the microneedle patch is used for rapid food testing with bare hands, the risk of contamination is high due to the small size of the microneedle patch and direct contact with the hand; if the microneedle patch is operated with gloves, it will be inconvenient for the user to operate.

[0019] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of the specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1

[0021] like Figure 1-3As shown, this embodiment provides a handheld microneedle usage device, which is characterized in that it includes a barrel cap 1, a barrel body 2 and a barrel bottom 3, the barrel body 2 is provided with a microneedle storage cavity 4 axially downward from the top, the microneedle storage cavity 4 is used to store the microneedle patch to be used, the barrel cap 1 is detachably connected to the upper part of the barrel body 2, the lower part of the barrel body 2 is detachably connected to the upper part of the barrel bottom 3, and the top of the barrel bottom 3 is provided with a microneedle mounting groove 5, which is used to clamp the microneedle.

[0022] The working principle and usage process of this embodiment are as follows:

[0023] The utility model usually combines the barrel cap 1, the barrel body 2 and the barrel bottom 3 together. After the barrel cap 1 is removed, the microneedle patch to be used can be stored in the microneedle storage cavity 4, and then the barrel cap 1 is installed to isolate the microneedle patch from the outside world to ensure the hygiene of the microneedle patch. When the microneedle patch needs to be used, the barrel cap 1 is removed, the microneedle patch is taken out of the microneedle storage cavity 4, and then the barrel bottom 3 is removed. There is a microneedle mounting groove 5 on the top of the barrel bottom 3. The microneedle patch is installed in the microneedle mounting groove 5 with the needle side facing up. When in use, directly take the barrel bottom 3 and press the barrel bottom 3 with the microneedle patch to the surface of the object to be detected, and then perform subsequent extraction and color indication.

[0024] Example 2

[0025] like Figure 1 、 2 As shown in Figures 4 and 5, this embodiment is developed on the basis of the above embodiments. Specifically, this embodiment defines the installation method of the barrel cap 1 and the barrel body 2. The barrel cap 1 is covered on the upper part of the barrel body 2, and the upper outer wall of the barrel body 2 is in contact with the inner wall of the barrel cap 1. The barrel cap 1 can be firmly mounted on the barrel body 2 through the action of friction.

[0026] Example 3

[0027] like Figure 1-3 As shown, this embodiment is developed on the basis of the above embodiment. Specifically, this embodiment defines the installation method of the barrel bottom 3 and the barrel body 2. The barrel body 2 is provided with a accommodating cavity 6 axially upward from the bottom. The upper part of the barrel bottom 3 is inserted into the accommodating cavity 6. The upper outer side wall of the barrel bottom 3 is in contact with the side wall of the accommodating cavity 6. The installation and fastening of the barrel bottom 3 and the barrel body 2 can be ensured by friction. At the same time, the accommodating cavity 6 is provided, and the upper part of the barrel bottom 3 is placed in the accommodating cavity 6. It is isolated from the outside when not in use, thereby reducing the risk of contamination of the microneedle mounting groove 5.

[0028] Furthermore, if Figure 3 As shown, the upper portion of the cylinder bottom 3 is a frustum structure, which is used to prevent the upper portion of the cylinder bottom 3 from being too slender, thereby preventing shaking when the cylinder bottom 3 is pressed.

[0029] Example 4

[0030] like Figure 1 、 2 As shown in Figures 4 and 5, this embodiment is developed based on the above embodiment. Specifically, the upper and lower parts of the barrel body 2 have a stepped transition structure, and the diameter of the upper part is smaller than the diameter of the lower part. When the barrel cap 1 is placed on the upper part of the barrel body 2 and slides downward, it can abut against the lower part of the barrel body 2, thereby ensuring that the barrel cap 1 is properly installed.

[0031] Example 5

[0032] like Figure 1 、 2 As shown in Figures 4, this embodiment is developed on the basis of the above embodiments. Specifically, the outer wall diameters of the tube cap 1, the lower part of the tube body 2 and the lower part of the tube bottom 3 are the same, so that they look beautiful when assembled together and are convenient to pick up without hurting the hands.

[0033] Example 6

[0034] like Figure 3 As shown, this embodiment is developed on the basis of the above embodiment. Specifically, the depth of the microneedle storage cavity 4 is 4-6 cm, preferably 5 cm, so that at least ten microneedle patches can be stored in the microneedle storage cavity 4.

[0035] The above description of the embodiments is intended to enable those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
