Description

Pre-adjusting method of treatment device for wound warning tape of oncology infusion port

Technical Field

The application relates to the technical field of oilfield water injection, in particular to a pre-adjusting method of a treatment device for a wound warning tape of an infusion port in an oncology department.

Background

Oncology patients require continuous injections of chemotherapy and other drugs, and many of the drugs are more hypertonic and irritating, requiring either PICC or port placement. A peripheral vein implanted Central venous Catheter (peripheral Inserted Central Catheter) is a Catheter which is provided with a peripheral vein puncture cannula and a head end positioned in a superior vena cava or a subclavian vein and is used for providing medium-term and long-term (7 days to 1 year) venous transfusion treatment for a patient. PORT (PORT) is a closed infusion device that is fully implanted in the body and includes a catheter portion having a tip located in the superior vena cava and an injection site that is implanted subcutaneously.

Both PICC and port require regular maintenance. PICCs require weekly maintenance, while ports require monthly maintenance. Many oncology patients are high in age, often miss dates due to the fact that the maintenance dates are not remembered, and thousands of yuan of infusion devices have to be removed and replaced, so that the economic cost and the pain of the patients are greatly increased. Therefore, many hospitals now post an adhesive tape on the surface of the wound protection film after maintaining the port, and record the maintenance date, the maintenance personnel, the basic information of the patient, contraindications, and the like. However, the patients are very many in one day, and the conventional method is to manually write the date on the adhesive tape, which is time-consuming, so that a device capable of automatically extracting the adhesive tape, imprinting information and pre-cutting is required.

As a further embodiment, the right blade edge of the toothed cutter head is shaped like teeth.

Has the beneficial effects that:

the device for processing the warning adhesive tape for the wound of the transfusion port in the oncology department is reasonable in structure and simple to operate, the back of the adhesive tape can be imprinted with pre-engraved information through the imprinting device by pulling the adhesive tape, and the adhesive tape is cut and formed with tooth marks through the mark cutting device, so that a user can tear the adhesive tape conveniently.

According to the device for processing the wound warning tape of the transfusion port in the oncology department, the self-locking effect of the matching of the worm gear and the worm gear is utilized between the output worm and the worm gear hole, so that power can be transmitted to the worm gear hole and the roller body from the output worm in a one-way mode, the rotation of the output worm cannot be influenced by the roller body and the worm gear hole, and the roller body has good posture stability:

the inclined inner groove of the stamping inner groove can unidirectionally drive a stamping deflector rod and a follow-up square rod of the stamping device to overcome the resistance of a stamping spring to retract leftwards for storing force, and then the stamping spring can drive the follow-up square rod and the stamping body to move rightwards to perform stamping action when the stamping deflector rod enters the straight-through inner groove;

the inclined outer groove of the cut mark outer groove can unidirectionally drive the cut mark deflector rod and the cut mark base of the cut mark device to retract leftwards to overcome the resistance of the cut mark spring to store force, and then the cut mark spring can drive the cut mark base and the tooth-shaped cutter head to perform cut mark action rightwards when the cut mark deflector rod enters the straight-through outer groove.

According to the device for processing the warning adhesive tape for the wound of the transfusion port in the oncology department, the large reduction ratio of the worm gear is counteracted through the speed increasing effect of the transmission device, so that the action frequencies of the stamping device and the cutting mark device are not too low when a user extracts adhesive tape paper:

the driving gear and the first pinion have a large gear ratio, so that the adhesive tape paper can be drawn out a small distance to drive the first pinion, the first gearwheel, the output gear and the output worm to rotate for many turns, and the rotating speeds of the worm wheel hole and the roller body are not too low after the reduction of the worm wheel and worm structure.

The using method of the device for processing the warning tape for the wound of the transfusion port in the oncology department is simple to operate, information which is carved in advance can be impressed, and tooth marks are formed in advance to facilitate tearing of adhesive tape paper.

The use method of the device for processing the warning adhesive tape for the wound of the transfusion port in the oncology department can ensure that the adhesive tape is continuously extracted, the disposal buffer device can ensure that the adhesive tape continuously outputs a small section of paper when the roller body stops rotating temporarily, the continuity and the hand feeling of a user for extracting paper towels are ensured, and the adhesive tape is clamped and stopped once without rotating for one circle on the roller body:

under a normal state, the torsion spring acts on the buffer winding coil to enable the buffer winding coil to rotate clockwise and abut against the limit stop;

when the impressing deflector rod enters the leftmost end of the straight-through inner groove, the shear mark deflector rod just enters the leftmost end of the straight-through outer groove, the ejection roller is blocked and temporarily stops rotating at the moment, the adhesive tape paper is still continuously drawn out by a user, and the paper-out buffering device performs paper-out buffering action at the moment: the adhesive tape is pulled and tightened, the buffer winding is driven to overcome the torsion force of the torsion spring so as to flatten the buffer winding, and the adhesive tape a releases a small section of adhesive tape in the state that the ejection roller is clamped.

The paper outlet buffer device ensures the continuity of the adhesive tape paper extracted by a user, and the adhesive tape paper is blocked and stopped once without rotating the roller body for a circle.

More importantly, the paper output buffer device also avoids the jamming of the stamping device and the cutting mark device which can be caused by directly drawing the adhesive tape paper:

when the roller body stops and continues to pull the adhesive tape paper, the acting force of the stamping deflector rod and the straight-through inner groove is too large, so that the stamping deflector rod cannot slide in the straight-through inner groove, and the stamping device cannot perform stamping action; the force of the score shift lever and the through outer groove is too large to cause the score shift lever to be incapable of sliding in the through outer groove, and the score device cannot execute the score action.

As a further embodiment, the outer wall of the fixed middle cylinder is in an inverted cone shape with a wide upper part and a narrow lower part, and the inner edge of the adjusting worm wheel is an inverted cone-shaped hole matched with the fixed middle cylinder; thanks to the improved structure, the adjusting worm wheel can stably rotate without moving up and down.

Of course, the discharge buffer device may also be configured to break the adhesive tape a which may be caused by forcibly pulling the adhesive tape in a state where the roller body is stopped.
