Description

Technical Field

[0001] This utility model relates to the field of sterile protective sleeve threading technology, and in particular to a sterile protective sleeve threading machine. Background Technology

[0002] In the medical field, the sterility of medical devices is a core element in ensuring patient safety and preventing postoperative infections. For medical devices that need to be reused or used in a sterile surgical environment, wearing a sterile protective sleeve can effectively block external bacteria, viruses, dust, and other contaminants, preventing the device from being contaminated during transportation and storage.

[0003] Traditional sterile protective sleeves for medical devices often require manual operation for application. These sleeves are typically made of plastic, and manually applying them involves twisting the opening open with fingers. To avoid contaminating the sleeve, staff must wear gloves. Wearing gloves further complicates the process of twisting the opening open, resulting in low efficiency and failing to meet the rapid turnover needs of large numbers of medical devices in hospitals. Utility Model Content

Staff need to wear gloves and use their fingers to open the opening of the sterile protective sleeve. However, the presence of gloves increases the difficulty of operation, making the process of opening the sleeve cumbersome, which seriously affects the efficiency of putting on sterile protective sleeves and makes it difficult to meet the needs of hospitals for rapid turnover of a large number of medical devices.

A rectangular lifting housing is fixedly connected to the lower end of the telescopic rod of the first electric push rod.

[0009] Furthermore, the negative pressure fixing assembly includes a negative pressure cylinder and a second electric push rod. The negative pressure cylinder is fixedly embedded inside the rear end face of the fixing frame, and a piston rod is slidably connected inside the negative pressure cylinder. A piston is fixedly connected to the front end of the piston rod, and the piston is in close contact with the inner circumferential surface of the negative pressure cylinder.

[0038] The lifting mechanism 4 includes a first electric push rod 401, which is installed on the top surface of the fixed frame 3. The telescopic rod of the first electric push rod 401 passes through the top surface of the fixed frame 3. The lower end of the telescopic rod of the first electric push rod 401 is fixedly connected to a rectangular lifting housing 402. The lifting mechanism 4 is used to move the upper three-way pipe 503 and the upper suction cup 504 up and down.

[0039] The negative pressure fixing assembly 5 includes a negative pressure cylinder 501 and a second electric push rod 507.

[0041] Example 2, based on Example 1, such as Figure 2 and Figure 6 As shown, the clamping assembly 7 includes two support blocks 701, which are fixedly connected to the right side of the T-shaped vertical plate 102. A clamping screw 702 is rotatably connected between the two support blocks 701. The clamping screw 702 has two reverse threads arranged symmetrically on its exterior. Two clamping plates 703 are connected to the exterior of the clamping screw 702 through the two reverse threads. Each clamping plate 703 has two trapezoidal sliders, which are slidably connected to the trapezoidal groove 104. A V-shaped clamping groove is opened in the middle of the opposite surface of the two clamping plates 703. The V-shaped clamping groove can make the clamping of cylindrical medical devices more secure. The clamping assembly 7 can quickly clamp and position the medical device, which facilitates the subsequent wearing of sterile protective sleeves.

[0042] The working principle of this embodiment is as follows: When in use, the medical device is first placed between the two clamping plates 703, and then the clamping screw 702 is rotated. At this time, the two clamping plates 703 move in opposite directions simultaneously under the action of the two reverse threads on the outside of the clamping screw 702, thereby clamping and positioning the medical device.

[0043] Next, the staff places the opening of the sterile protective sleeve onto the two suction cups 504 below. Then, the PLC programmable controller 103 controls the extension rod of the first electric push rod 401 to extend downwards, thereby moving the rectangular lifting housing 402, the upper three-way fitting 503, and the two upper suction cups 504 downwards, so that the two upper suction cups 504 contact the upper outer side of the sterile protective sleeve. Then, the PLC programmable controller 103 controls the extension rod of the second electric push rod 507 to extend backwards, moving the piston rod 505 and piston 506 backwards, thereby drawing air from inside the four suction cups 504, the two three-way fittings 503, and the two hoses 502 into the negative pressure cylinder 501, creating negative pressure inside the four suction cups 504, thereby suctioning the upper and lower surfaces of the sterile protective sleeve. Then, the PLC programmable controller... The controller 103 controls the telescopic rod of the first electric push rod 401 to retract upwards, moving the rectangular lifting housing 402, a three-way fitting 503 above, and two suction cups 504 above upwards, thereby opening the opening of the sterile protective sleeve. Then, the PLC programmable controller 103 starts the fan 8, and the airflow blown by the fan 8 enters the inside of the sterile protective sleeve, blowing it open. Next, the PLC programmable controller 103 controls the servo motor 202 to operate, thereby rotating the threaded rod 203. At this time, the displacement seat 201 moves to the left under the action of the thread, carrying the negative pressure fixing component 5, the lifting mechanism 4, and the sterile protective sleeve, thereby automatically putting the sterile protective sleeve on the outside of the medical device. In this process, since there is no need for manual opening of the sterile protective sleeve with fingers, the wearing efficiency of the sterile protective sleeve is improved.
