Description

Technical Field

[0001] The invention relates to the field of medical machinery, and in particular to a handheld medical garbage bag tie packaging device. Background Art

[0002] It is extremely important to properly handle medical waste to prevent non-contact infection. When the existing medical waste bags are full, medical staff are required to pack and collect the medical waste bags for centralized treatment. However, when packing, medical staff directly touch the bag opening of the garbage bag, which increases the risk of infection for medical staff. In addition, since patients generate too much garbage and waste, the capacity of medical waste bags is relatively large. When packing, medical staff have a slow packing speed and weak tightening force on the bag opening. When transporting medical waste, the garbage in the medical waste bag is easy to leak out. In addition, manual packing cannot link the infectious garbage information with the information of the medical staff who packed it. If highly infectious garbage is leaked, it cannot be held accountable in time. Summary of the invention

[0003] The technical problem to be solved by the present invention is that when packing is done manually, the packing speed is slow and the tightening force on the bag mouth is small.

[0029] The side of the conveying roller 34 is provided with a knurling pattern, which can increase the friction between the roller and the tie 31 to prevent slipping during tying, increase the tightening force of the medical waste bag mouth, and prevent medical waste from leaking out of the medical waste bag.

[0030] The cable tie 31 is a commonly used nylon cable tie 31 , and the cable tie 31 includes a head 32 and a tail 33 . When in use, the tail 33 can be inserted into the head 32 .

[0031] An arc-shaped baffle plate 24 is fixed on the gun outlet of the housing 1. The arc-shaped baffle plate 24 can facilitate the neck of the garbage bag to be mounted on the hook a5 to prevent the mouth of the garbage bag from spreading.

[0032] The cable tie set 6 includes multiple rows of cable ties 31 , the heads 32 of two cable ties 31 are bonded together by adhesive, and the tails 33 of the cable ties 31 are inserted into the heads 32 , so that the cable ties 31 are tied into a U-shaped cavity 11 , and the U-shaped cavity 11 can be sleeved on the sleeve 4 .

[0033] The right end of the sleeve 36 is fixed in the gun barrel, and the gap between the sleeve 4 and the left side of the shell 1 is 2-3mm, so that the cable tie 31 can be packaged through the 2-3mm gap to prevent the sleeve 36 from affecting the packaging of the medical waste bag.

A groove matching the elastic card 20 is provided on the left side plate 35 of the shell 1, and the elastic card 20 can be clamped in the groove, so that the left side plate 35 of the shell 1 is fixed. Opening the left side plate 35 of the shell 1 is convenient for inspecting the packaging device or replacing the cable tie group 6. An observation port 25 is provided on the left side plate 35 of the shell 1, and whether the cable tie 31 is sufficient can be observed through the observation port 25.

[0037] A hook b is provided below the weighing module 29 to facilitate weighing by medical staff.

[0038] A card reader is fixed on the top of the housing 1, and medical staff can swipe their work ID card on the card reader to read the work information of the medical staff.

[0039] A through hole 30 is provided on the upper side of the mounting base 11 for the tail 33 to pass through. When the cable tie 31 reaches the left side of the shell 1, the tail 33 of the cable tie 31 just passes into the through hole 30. When tying the cable tie, the conveying rod 34 drives the tail 33 to pass into the through hole 30 to prevent the mounting base 11 from affecting the tying and packaging operation.

[0040] The control switch 15 at the trigger of the pistol has four working states. When the trigger is pressed for the first time, the display screen 13 is turned on, and the display screen 13 displays whether the packaging device is in a normal state, such as: whether the power is normal, whether the cable tie 31 is sufficient, etc.; when the trigger is pressed for the second time, the barcode scanner 12 is turned on, and the medical staff will need to scan their work permits and the garbage information on the medical waste bag, and send it to the display screen 13, which is displayed on the display screen 13; the medical staff hangs the neck of the medical waste bag on the hook a5, and presses the trigger for the third time to start the packaging operation; when the trigger is pressed for the fourth time, the weighing module 29 is turned on, and the garbage bag is hung on the hook b on the weighing module 29, and weighing starts, and the record is sent to the display screen 13, and displayed on the display screen 13.

[0041] It is worth noting that the weighing module 29 is a commonly used technology in this field and can be purchased in real life. In addition, a controller is also provided in this patent, which connects the barcode scanner 12, the weighing module 29, the first motor 3, the second motor 88, the display screen 13, and the control switch 15. These are all commonly used technologies in this field and will not be described in detail in this patent.

[0042] Before use: the baffle 28 pushes the cable tie set 6 against the left side surface of the housing 1, the two rollers are separated, and the tail 33 of the cable tie 31 is just between the two rollers.

[0043] First, the medical staff presses the trigger for the first time, and the display screen 13 is turned on. The display screen 13 displays whether the packaging device is in a normal state, such as whether the power is normal, whether the cable tie 31 is sufficient, etc. If the indicators of various aspects of the packaging device are normal, it can continue to be used; the trigger is pressed for the second time, and the barcode scanner 12 is turned on. The medical staff will need to scan their work permit and the garbage information on the medical waste bag. The medical staff observes the information on the display screen 13 (such as the work permit number, name, position, department where the medical waste bag is located, and whether it is radioactive) on the medical staff's work permit. and so on) are correct; then the medical staff hangs the neck of the medical waste bag on the hook a5, and the hanging method is: fold the neck of the medical waste bag in half and then hang it on the hook a5, or twist the neck of the medical waste bag into a twist shape, fold it in half and hang it on the hook a5; press the trigger for the fourth time, turn on the first motor 3, the first motor 3 rotates, thereby driving the lead screw 2 to rotate, so that the cylinder moves horizontally, and the hook a5 pulls the bag neck into the shell 1. When the bag neck is completely collected in the shell 1, the first motor 3 stops rotating, and the third motor 9 is turned on to drive the herringbone connecting rod assembly 10 rotates, so that the driven roller is closely attached to the active roller, so that the active roller and the driven roller clamp the tail 33 of the cable tie 31, the third motor 9 stops rotating, the second motor 8 is turned on, driving the active roller to rotate, thereby pulling the tail 33 of the cable tie 31 to move, so that the mouth-shaped cavity 11 gradually shrinks, thereby tying the medical waste bag, when the medical waste bag is tied, the third motor 9 continues to move, and the adhesive on the head of the pulling cable tie 31 is separated from the cable tie group 6, so that the cable tie 31 is separated from the cable tie group 6, the second motor 8 stops rotating, and the third motor 9 reverses. The driven roller will be moved away from the active roller, and the cable tie 31 will no longer be pressed between the conveying rollers 34, and the packaging is completed; the first motor 3 reverses to send the packaged medical waste bag out of the shell 1, and the medical staff takes out the medical waste bag; the trigger is pressed for the fourth time, the weighing module 29 is turned on, and the neck of the packaged medical waste bag is hung on the hook b of the weighing module 29, and weighing begins, and the record is sent to the display screen 13, and displayed on the display screen 13. After the medical staff reads the information, the trigger is pressed for the fifth time, and the display screen 13, the barcode scanner 12, and the weighing module 29 are turned off.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
