Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a cabinet-type automatic destruction and disposal of egg retrieval needles recycling device. Background Technology

[0002] In assisted reproductive technology, an egg retrieval needle is a specialized needle used to perform egg retrieval via transvaginal puncture under ultrasound guidance. This needle is characterized by its exceptionally long and narrow body and requires careful handling after each single use.

[0003] Currently, there are two main methods for disposing of discarded oocyte retrieval needles in clinical practice: one is to use a large sharps container to store them directly, but because the oocyte retrieval needles are long, conventional medical sharps containers are difficult to hold them effectively and they are easily punctured; the other is for medical staff to manually fold or coil the discarded oocyte retrieval needles before putting them into the sharps container, which poses a significant risk of occupational exposure and can easily cause iatrogenic injuries.

[0004] Designing a safe and efficient device for disposing of discarded oocyte retrieval needles, enabling medical staff to automatically destroy the needles without manual intervention, thereby avoiding occupational exposure risks, is a pressing technical problem in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a cabinet-type automatic destruction and disposal of waste oocyte retrieval needles. Through cabinet-type design and automated control, it reduces the occupational exposure risk of medical staff and improves the safety and convenience of disposal of waste oocyte retrieval needles.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0011] A control panel is installed on the front side of the cabinet, and a counter is installed on the control panel.

[0012] Furthermore, the top of the cabinet is recessed inward to form a slope, and the inlet assembly is disposed on the slope. Multiple elastic anti-rebound baffles are evenly disposed on the inner wall of the inlet assembly.

[0013] Furthermore, the surface of the spiral roller is machined with a spiral groove, the width of which is slightly larger than the diameter of the egg-collecting needle. The spiral roller is fixed to the inner wall of the cabinet by bearing seats at both ends.

[0014] Furthermore, the clamping wheel is connected to the cabinet via a spring mechanism, which includes a compression spring and an adjusting bolt.

[0015] Furthermore, the guide plate is arc-shaped and maintains a gap with the surface of the spiral roller, and the upper end of the guide plate is connected to the lower end of the inlet assembly.

[0016] Furthermore, the foot pedal is connected to the bottom of the cabinet via a hinge, and the rear end of the foot pedal is connected to the drive shaft via a connecting rod. The drive shaft is equipped with a ratchet, which is engaged with a pawl via a torsion spring.

[0017] Furthermore, the collection component has a drawer-type structure and is connected to the cabinet via a slide rail. An infrared full-load sensor is installed above the collection component.

[0018] Furthermore, a transparent observation window is provided on the front side of the cabinet.

A transparent door for observation is provided on the front side of the cabinet body 1, and a control panel 11 is installed on the upper part of the front side of the cabinet body 1, and a counter 13 is provided on the control panel 11. During operation, the egg collection needle enters through the inlet assembly 2. After detection by the sensor 12, the motor 9 is activated. Guided by the guide plate 5, the egg collection needle enters the groove of the spiral roller 3. Driven by the motor 9 and the pressure wheel 4, it is deformed. The operator can provide auxiliary power through the foot pedal 6. After being deformed, the egg collection needle falls into the collection assembly 10 for collection by gravity.

[0035] like Figure 1 As shown, the cabinet 1 of this utility model is made of stainless steel and is generally rectangular column-shaped. The cabinet 1 has a front door connected by hinges, and a transparent observation window is provided on the door. The top of the cabinet 1 is recessed inward to form a slope, which is inclined to the horizontal plane, and an inlet 2 is opened on this slope. The inlet 2 is generally funnel-shaped, with the upper opening larger than the lower opening, and a smooth transition inside. Multiple elastic anti-rebound baffles are evenly arranged on the inner wall of the inlet 2. These baffles are made of elastic stainless steel and are distributed in a fan shape. An infrared sensor 12 is located directly below the inlet 2, and the sensor 12 is fixed to the inner wall of the cabinet by a bracket.

[0036] like Figure 2 As shown, the deformation mechanism is located in the upper part of the interior of cabinet 1. Its core component is a spiral roller 3, which is made of bearing steel and has spiral grooves machined on its surface. The width of the grooves is slightly larger than the diameter of a standard egg-collecting needle. The roller 3 is fixed to the inner wall of cabinet 1 by bearing seats at both ends. Multiple sets of pressure rollers 4 are provided on one side of the roller 3. The pressure rollers 4 are made of wear-resistant material and maintain appropriate pressure through a spring mechanism. The spring mechanism includes a compression spring and an adjusting bolt, which can adjust the pressure as needed.

[0037] A guide plate 5 is installed on each side of the roller 3. The guide plate 5 is made of stainless steel and is arc-shaped, maintaining an appropriate gap with the surface of the roller 3. The guide plate 5 is fixed to the inner wall of the cabinet 1 by multiple bolts, and its position is adjustable. The upper end of the guide plate 5 is connected to the lower end of the inlet 2, forming a continuous guide channel to ensure that the egg collection needle can smoothly enter the groove of the roller 3.

[0038] like Figure 3 As shown, the drive mechanism is located at the bottom of cabinet 1 and employs a composite drive system of foot pedal 6 and motor 9. Foot pedal 6 protrudes from the bottom front of cabinet 1 and is formed by stamping from sheet metal of sufficient strength. Foot pedal 6 is connected to the bottom of cabinet 1 via hinges, and its rear end is connected to drive shaft 7 via a connecting rod. Drive shaft 7 is horizontally positioned at the bottom inside cabinet 1, and both ends are fixed by bearing seats. A ratchet 8 is mounted on drive shaft 7, and a pawl that meshes with ratchet 8 is kept engaged by a torsion spring.

[0039] The motor 9 is fixed to the bottom of the cabinet 1 by a bracket, and its output shaft is connected to the gearbox via a coupling. The reduced power is transmitted to the roller 3 through a chain drive system, enabling the roller 3 to rotate stably. The entire transmission system is protected by a chain cover seal.

[0040] The collection component 10 is located at the bottom of the cabinet 1 and includes a drawer-type collection box, which is connected to the cabinet 1 via a slide rail. An infrared full-load sensor is installed above the collection box to monitor the amount of waste stored.

[0041] The control panel 11 is installed on the upper front of cabinet 1 and uses a touch screen display to show the processing quantity and equipment status. The control system uses a programmable logic controller (PLC) and includes the necessary control modules. All electrical components are connected via terminal blocks, and the wiring is neat and standardized.

[0042] The specific working process of this utility model is as follows:

[0043] 1. The operator inserts the discarded egg collection needle into the inlet 2. After the infrared sensor 12 detects the egg collection needle, the control system starts the motor 9.

[0044] 2. Under the influence of gravity and the guidance of the guide plate 5, the egg-collecting needle enters the groove of the spiral roller 3;

[0045] 3. The operator can step on the foot pedal 6 as needed to provide additional power to the roller 3 through the ratchet mechanism;

[0046] 4. Under the action of the spiral groove of roller 3 and the pressure wheel 4, the egg-collecting needle is forced into a spiral shape, thus completing the destruction of its shape;

[0047] 5. The deformed egg-collecting needle falls from below the roller 3 and enters the collection box 10 through the guide groove;

[0048] 6. The control system records the number of processes. When the preset number is reached or the collection box is full, the touch screen displays a reminder message.

[0049] All components of this invention are connected using standard fasteners, facilitating maintenance and replacement. All exposed edges are rounded to ensure safe operation. The overall design complies with relevant standards for medical device products.

[0050] In summary, the cabinet-type automatic waste egg retrieval needle recycling device provided by this utility model, through its cabinet design, ensures that the height of the input port conforms to the operating habits of medical personnel, reducing the risk of occupational exposure; the combined drive method of motor drive and foot pedal assistance avoids the safety hazards that may be caused by manual bending, while the foot pedal structure design allows medical personnel to completely remove their hands from the work area, further improving operational safety; the destructive structure design of the spiral roller combined with the pressure wheel can evenly curl the egg retrieval needle, significantly reducing its volume and facilitating subsequent processing; the guide plate ensures that the egg retrieval needle can stably enter the destructive area, preventing the needle from jumping; the cooperation of the sensor and control system realizes automated operation, reducing the workload of medical personnel; the counter facilitates the statistical management of medical waste; and the drawer-type collection box design facilitates the collection and transportation of waste.
