Description

Technical Field

[0001] The invention belongs to the technical field of bandaging devices, in particular to a bandaging device with a bandaging tape unwinding and cutting structure. Background Art

[0002] Bandaging is one of the important measures for emergency treatment at the scene of trauma. Timely and correct bandaging can achieve the purpose of compression hemostasis, reduce infection, protect wounds, reduce pain, and fix dressings and splints; on the contrary, incorrect bandaging can lead to increased bleeding, aggravated infection, new injuries, and sequelae. When a patient's arm is injured, it is usually necessary to wrap it with a bandage.

[0003] After searching, the publication number CN114631938A discloses a portable field care bandage reel and cutter, which includes a reeling mechanism, a mounting plate is fixedly disposed on the left side of the reeling mechanism, a conveying mechanism is fixedly disposed on the rear end of the mounting plate, a connecting plate is fixedly disposed on the upper left end of the outer wall of the reeling mechanism, a cutting mechanism is slidably penetrated on the top of the connecting plate, and a finger ring is fixedly disposed on the bottom of the reeling mechanism.

[0004] The above-mentioned bandaging device can integrate the functions of winding and cutting the bandage, so that medical staff only need to carry one number of the device to complete the winding and cutting of the bandage. It can be seen that by using the device in the present application, the convenience of medical staff in carrying medical appliances is ensured, but there are still the following problems:

[0050] A method for using a bandaging device with a bandaging tape unwinding and cutting structure, which is used for the use instructions of the above-mentioned bandaging device with a bandaging tape unwinding and cutting structure, is characterized in that it comprises at least the following steps:

[0051] S1, open the bandage placement box 9, insert the hollow column 11 into the installation column 12, fix it through the fixing plate 18, complete the installation of the bandage 10, pull the outer end of the bandage 10, pass it through the two auxiliary rollers 23, and pull it out from the right side outlet of the bandage placement box 9;

[0052] S2, close the bandage placement box 9, put the patient's injured arm into the arm placement slot 5, fix the pulled-out end of the bandage 10 on the patient's arm, and with the cooperation of the fixed gear ring 3 and the movable gear 6, make the bandage placement box 9 rotate around the patient's arm;

[0053] S3, while the bandage placement box 9 rotates, the support plate 2 is translated forward and backward along the patient's arm under the action of the guide screw 35 at the bottom, so that the bandage 10 can be wrapped around the injured part of the patient;

[0054] S4. After the wrapping is completed, the bandage 10 at the outlet of the bandage placement box 9 is fixed by the U-shaped fixing plate 28, the push rod 29 is pressed, and the bandage 10 is cut by the cutting blade 32. The cut bandage 10 is fixed to the patient's arm using a sticky item such as tape.

[0055] Working principle:

[0056] First, when in use, rotating the handle 14 drives the supporting screw 13 to rotate, and under the action of the thread, the screw sleeve block 15 moves backward, because the screw sleeve block 15 is movably pinned with the adjusting plate 17, the adjusting plate 17 is movably pinned with the mounting column 12, and the adjusting plate 17 is movably pinned with the fixing plate 18. The fixing plates 18 on both sides are retracted and closed under the action of the adjusting plates 17, and the hollow column 11 is inserted into the outer side of the mounting column 12, and the handle 14 is released. Since the screw sleeve block 15 is elastically connected to the mounting column 12 through the fixing spring 16, the fixing spring 16 pushes the handle 14 forward under the elastic force of the fixing spring 16, so that the fixing plates 18 on both sides are opened to fix the hollow column 11. On the other side, the cross-shaped shaft 21 is aligned with the positioning groove 20 and inserted, and the installation of the bandage 10 can be completed. The second motor 22 is started to drive the cross-shaped shaft 21 to rotate, so that the hollow column 11 rotates accordingly, and the automatic unwinding of the bandage 10 is realized.

[0057] Secondly, when in use, the patient's arm is placed in the arm placement slot 5, and the first motor 8 is started to drive the movable gear 6 to rotate under the action of the first drive shaft. Since the fixed gear ring 3 is engaged with the movable gear 6, and the guide ring groove 4 and the guide column 7 cooperate with each other, the movable gear 6 drives the bandage placement box 9 to rotate around the arm placement slot 5.

[0058] Next, when in use, the third motor 39 is started to drive the guide screw 35 to rotate, and under the action of the thread and the sliding sleeve block 38, the screw slider 36 pushes the support plate 2 to move forward and backward along the support slide rod 37.

[0059] Then, when in use, the rotating handle 27 drives the fixed gear 26 to rotate under the action of the second drive shaft. Since the tooth groove 25 is engaged with the fixed gear 26, the movable plate 24 can move vertically, so that the movable plate 24 pushes the U-shaped fixed plate 28 downward to fix the bandage 10 at the outlet of the bandage placement box 9.

[0060] Finally, when in use, press the push rod 29 to make the cutting knife seat 31 drive the cutting blade 32 to move downward, cooperate with the groove 34 below, and cut the fixed bandage 10. After cutting, release the push rod 29. Since the push rod 29 is elastically connected to the movable plate 24 through the reset spring 30, under the action of the reset spring 30, the push rod 29 is pushed to drive the cutting blade 32 to move upward, and a rubber pad is set to protect the cutting blade 32.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
