Description

Technical Field

[0001] This utility model relates to the field of medical testing equipment technology, and in particular to an automatic detachable card-type sample injection testing device. Background Technology

[0002] With the development of modern medical diagnostic technology, card-based sample testing equipment has been widely used in primary healthcare, disease screening, and emergency testing due to its ease of operation and rapid response. These devices typically use pre-made reagent cards as sample carriers. The sample card is manually pushed into the device for testing, and after testing, the used sample card is manually removed by medical staff.

[0003] However, in practical applications, this traditional method of sample introduction and disposal has revealed some technical shortcomings. First, the installation and deployment of the equipment often requires considerable time and operational steps, especially in scenarios requiring rapid response, such as outdoor emergency or temporary testing sites. The cumbersome installation process significantly impacts work efficiency and the timely activation of the equipment. Second, and more critically, when medical personnel manually remove used sample cards, it inevitably increases the number of direct or indirect contacts with the samples. These used sample cards may contain biological contaminants, posing a potential risk of cross-infection and contamination spread to medical personnel during handling. Furthermore, the manual removal method makes the entire testing process less automated and streamlined, impacting the efficiency of large-scale testing to some extent.

[0004] Therefore, in order to address the shortcomings of existing card-type sample injection testing equipment in terms of ease of installation, sample processing safety, and efficiency, this utility model proposes an automatic detachable card-type sample injection testing device, which aims to simplify the equipment deployment process and achieve contactless automated disposal of sample cards after testing. Utility Model Content

The protective shell is fixedly connected to the outside of the shielding shell. The telescopic block is slidably disposed in a groove opened inside the protective shell. The spring is disposed on one side of the telescopic block and applies elastic force to it. The telescopic block achieves quick locking by cooperating with the locking structure of the pre-installed post, while the sliding block contacts the other end of the telescopic block to achieve the unlocking function.

[0009] Furthermore, the detection probe in the auxiliary mechanism is fixedly connected to one end of the sliding column, the sliding column is slidably fitted inside the fixed column, the release control lever is rotatably connected to the rotating shaft, and switches between the horizontal and vertical positions by the attraction and disengagement of the electromagnet, thereby realizing the support and release of the sample card.

[0010] Preferably, the inner side of the protective shell is provided with a groove for the telescopic block to slide, and one end of the telescopic block is provided with a locking bevel that cooperates with the pre-installed column.

[0011] Preferably, one end of the sliding block is provided with an unlocking ramp that cooperates with the telescopic block.

[0012] Preferably, the shield housing has a sample inlet at the top and a sample outlet at the bottom.

[0013] Preferably, when the electromagnet is energized, the release control lever remains horizontal, and when the electromagnet is de-energized, the release control lever rotates around the pivot to a vertical downward position.

[0014] Preferably, the outer periphery of the sliding column is slidably fitted with the inner wall of the fixed column, and the other end of the sliding column is fixedly connected to the detection probe.

[0019] 2. This utility model, by designing an electromagnetically controlled detachment lever, realizes the vertical injection of sample cards and automatic gravity detachment after testing, solving the problem that the sample card removal method in the prior art increases the number of times medical staff come into contact with the sample and poses a risk of contamination.

[0031] Example:

[0032] Reference Figures 1 to 4 This utility model provides an automatic detachable card-type sample injection and detection device, which aims to solve the problems of time-consuming installation and disassembly, complex operation, and increased risk of contamination due to contact between medical staff and samples caused by the sample card removal method in the prior art.

[0033] like Figure 1 and Figure 2 As shown, the automatic detachable cartridge sampling and detection device includes a shield housing 23 and a fixing component 5 fixedly connected to the outside of the shield housing 23. The shield housing 23 serves as the core carrier of the entire device and the housing space for the internal mechanisms. The fixing component 5 enables the device to be quickly installed and removed from the preset position.

[0034] A protective cover 4 is provided on the top of the shielding housing 23. The protective cover 4 is rotatably connected to the top of the shielding housing 23 via a rotating shaft 3. The protective cover 4 is opened before testing to facilitate the vertical insertion of the sample card into the device from the inlet. After testing, it is closed to prevent dust and protect the internal structure. The rotating shaft 3 ensures that the protective cover 4 can rotate smoothly around its axis, thereby realizing the opening and closing action of the protective cover 4.

[0035] An auxiliary mechanism 2 is installed inside the shielding housing 23. This auxiliary mechanism 2 is the key actuator for sample card detection and automatic detachment. The auxiliary mechanism 2 includes a sliding column 21, a fixed column 22, a rotating shaft 24, and a detachment control lever 25. The sliding column 21 is slidably fitted inside the fixed column 22. The reciprocating motion of the sliding column 21 within the fixed column 22 drives the detection probe 1 to perform sample detection. The rotating shaft 24 is rotatably connected inside the shielding housing 23, and the detachment control lever 25 is rotatably connected to the rotating shaft 24. The detachment control lever 25 is controlled by an electromagnet and is responsible for holding the sample card during sample injection and flipping it to detach the sample card after detection.

[0036] The fixing component 5 is responsible for the quick installation and unlocking of the device. The fixing component 5 includes a protective shell 51, a spring 52, a telescopic block 53, a pre-installed post 54, and a sliding block 55. The protective shell 51 is fixedly connected to the outside of the shield housing 23, serving as the carrier of the fixing component 5. The telescopic block 53 is slidably disposed within a groove opened in the protective shell 51, with one end having a locking bevel that engages with the pre-installed post 54. The spring 52 is disposed on one side of the telescopic block 53 and applies elastic force to it. The spring 52 is compressed when the telescopic block 53 is pressed by the pre-installed post 54 and rebounds after passing the locking point, thereby pushing the telescopic block 53 to lock the pre-installed post 54, achieving quick locking of the device. The pre-installed post 54 is a fixed point pre-installed at the desired location, forming a locking engagement with the telescopic block 53. The sliding block 55 is slidably disposed within the protective shell 51, with one end contacting one end of the telescopic block 53, and during unlocking, the pushing and pulling motion of the device causes the telescopic block 53 to disengage from the lock of the pre-installed post 54.

[0037] Reference Figure 3 and Figure 4 The auxiliary mechanism 2 includes a detection probe 1 that performs the detection function, which is fixedly connected to one end of the sliding column 21. The outer periphery of the sliding column 21 and the inner wall of the fixed column 22 form a sliding fit, and the fixed column 22 is fixed inside the shield housing 23. This structure allows the sliding column 21 to drive the detection probe 1 to make a stable reciprocating linear motion along the axial direction of the fixed column 22, thereby completing the scanning detection of the sample card placed in the device.

[0038] Meanwhile, the auxiliary mechanism 2 also includes a detachment control lever 25 for controlling the detachment of the sample card. The detachment control lever 25 is rotatably connected to the inside of the shield housing 23 via a rotating shaft 24 and is located below the movement path of the detection probe 1. The detachment control lever 25 is controlled by an electromagnet. When the electromagnet is energized, the detachment control lever 25 is attracted to a horizontal state, forming a platform that can support the sample card. When the detection is completed and the electromagnet is de-energized, the detachment control lever 25 rotates around the rotating shaft 24 to a vertically downward state under the action of gravity. At this time, the platform disappears, and the sample card naturally detaches from the sample outlet. This structural combination of the reciprocating motion of the detection probe 1 and the flipping motion of the detachment control lever 25 ensures that the sample can be discarded immediately, automatically, and without contact after the detection is completed, greatly improving the detection efficiency and reducing the risk of contamination.

[0039] As a preferred embodiment, in order to achieve reliable engagement and disengagement between the telescopic block 53 and the pre-installed column 54, please refer to... Figure 2 The inner side of the protective shell 51 is provided with a groove for the telescopic block 53 to slide, and one end of the telescopic block 53 is provided with a locking slope that cooperates with the pre-installed column 54. When the device pushes towards the pre-installed column 54, the locking slope guides the telescopic block 53 to retract and compress the spring 52. After passing the pre-installed column 54, it is locked into the back of the pre-installed column 54 under the elastic force of the spring 52.

[0040] As another preferred embodiment, in order to realize the unlocking function of the device, one end of the sliding block 55 is provided with an unlocking slope that cooperates with the telescopic block 53. When it is necessary to unlock, continue to push the device so that the telescopic block 53 contacts and passes the unlocking slope of the sliding block 55. When the device is pulled in the opposite direction, the telescopic block 53 can drive the sliding block 55 to move together and finally disengage from the lock with the pre-installed column 54.

[0041] As another preferred embodiment, in order to define the entry and exit path of the sample card, the top of the shield housing 23 is provided with an inlet and the bottom of the shield housing 23 is provided with an outlet. The inlet and outlet are connected in the vertical direction. The sample card is put in through the inlet and falls out through the outlet after the test is completed.

[0042] As another preferred embodiment, in order to accurately control the timing of sample card detachment, when the electromagnet is energized, the magnetic force generated by it attracts the detachment control lever 25 to keep it in a horizontal state. When the electromagnet is de-energized, the magnetic force disappears, and the detachment control lever 25 rotates around the rotating shaft 24 to a vertically downward state under the action of gravity.

[0043] As another preferred embodiment, in order to ensure the smoothness and accuracy of the movement of the detection probe 1, a sliding fit is formed between the outer periphery of the sliding column 21 and the inner wall of the fixed column 22, and the other end of the sliding column 21 is fixedly connected to the detection probe 1, thereby realizing the stable reciprocating movement of the detection probe 1.

[0044] As another preferred embodiment, one side of the protective cover 4 is rotatably connected to the top of the shield housing 23 via a pivot 3, which allows the protective cover 4 to be easily flipped up to expose the sample inlet below.

[0045] As another preferred embodiment, in order to ensure the stability of the sample card's attitude during vertical descent, the shield housing 23 is provided with a guide structure for accommodating the sample card. The guide structure can be a guide wall or a guide groove that cooperates with the side of the sample card.

[0046] The working principle is as follows:

[0047] During installation, first fix the pre-installed post 54 in the desired position, then align the protective shell 51 on the device shield housing 23 with the pre-installed post 54 and push it forward. During the pushing process, the telescopic block 53 inside the protective shell 51 is pressed backward because its locking ramp contacts the pre-installed post 54. The telescopic block 53 slides in the groove for sliding and compresses the spring 52 on one side. When the telescopic block 53 has completely passed the top of the pre-installed post 54, the spring force of the spring 52 will push the telescopic block 53 forward, so that it is locked behind the pre-installed post 54, thereby completing the quick fixing of the device. When it is necessary to unlock, continue to push the device forward. The telescopic block 53 will contact and pass the unlocking ramp of the sliding block 55. Then pull the device in the opposite direction. At this time, the telescopic block 53 will drive the sliding block 55 to slide on the pre-installed post 54 together until it is completely released from the lock with the pre-installed post 54.

[0048] During sample testing, the protective cover 4, which is connected to the rotating shaft 23, is first flipped upwards. At this time, the electromagnet is energized to generate magnetic force, which attracts the detachment control lever 25, which is connected to the rotating shaft 24, to a horizontal state, forming a temporary platform. The sample card is then placed into the sample inlet at the top of the shield housing 23. Guided by the internal guide structure, the sample card falls onto the detachment control lever 25. Subsequently, the control system drives the sliding column 21 to slide within the fixed column 22, which in turn drives the detection probe 1, which is fixedly connected to one end of the sliding column 21, to complete the detection of the sample card. After the detection is completed, the electromagnet is de-energized, the magnetic force disappears, and the detachment control lever 25 rotates vertically downwards around the rotating shaft 24 under the action of gravity. The sample card loses its support and naturally detaches from the sample outlet at the bottom of the shield housing 23.
