Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-pressure-injury indwelling needle. Background Art

[0002] Indwelling catheters facilitate clinical medication administration, emergency medication for critically ill patients, reduce nurse workload, and alleviate the pain of frequent punctures for patients. Therefore, they are widely used in clinical treatment. Indwelling catheters come in a variety of structural forms, such as arterial and venous catheters.

[0003] When using existing indwelling catheters, the infusion port device on the indwelling catheter is generally fixed to prevent the infusion port device from shaking and causing the indwelling catheter to accidentally fall off, causing unnecessary pain and additional expenses to the patient. However, overly firm reinforcement measures may also cause the infusion port device of the indwelling catheter to exert excessive pressure on the patient's skin, thereby causing pressure damage to the patient's skin and causing secondary damage to the patient during treatment.

[0004] Therefore, we propose an anti-pressure-injury indwelling needle. Utility Model Content

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides an anti-pressure-injury indwelling needle.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an anti-pressure injury indwelling needle, comprising an indwelling needle seat, a fixed dressing is provided on the front of the indwelling needle seat, an infusion connecting hose is fixedly installed on the bottom of the indwelling needle seat, an outer wall of the infusion connecting hose is provided with a blocking buckle, an anti-pressure injury infusion port device is fixedly installed on the end of the infusion connecting hose away from the indwelling needle seat, an anti-pressure injury fixed dressing is provided on the back of the anti-pressure injury infusion port device, the anti-pressure injury infusion port device comprises an anti-pressure injury component, the front end of the outer wall of the anti-pressure injury component is threadedly connected to the infusion port tube, the anti-pressure injury component comprises a first mounting tube, and a second mounting tube is fixedly installed on the bottom of the first mounting tube.

[0007] Preferably, a connecting tube is fixedly mounted on the bottom of the second mounting tube, and the bottom of the connecting tube is fixedly connected to an end of the infusion connecting hose away from the indwelling needle seat.

[0008] Preferably, a butterfly-shaped silicone anti-pressure support is fixedly installed on the rear end of the outer wall of the second mounting tube, and the back side of the butterfly-shaped silicone anti-pressure support is fixedly connected to the front side of the anti-compression injury fixed dressing.

[0013] Preferably, a covering film is movably bonded to the back surface of the anti-pressure dressing body.

[0014] Beneficial effects

[0015] The utility model provides an anti-pressure indwelling needle with the following beneficial effects:

[0016] (1) The anti-pressure indwelling needle is provided with an anti-pressure infusion port device and an anti-pressure fixed dressing with good viscosity. The infusion port tube on the anti-pressure infusion port device passes through the fixed port on the anti-pressure fixed dressing, so that the anti-pressure fixed dressing will not excessively press the patient's skin when fixing the anti-pressure infusion port device. The butterfly-shaped silicone anti-pressure support on the anti-pressure infusion port device can play a buffering and protective role for the contact surface between the anti-pressure component and the patient, further avoiding excessive pressure on the patient's skin and causing pressure damage to the patient's skin.

[0017] (2) The anti-pressure indwelling needle is provided with an infusion port tube, which is threadedly connected to the threaded tube. This not only improves the fixing effect of the entire infusion port tube, but also facilitates the disassembly and assembly of the infusion port tube, thereby improving the disassembly and assembly efficiency of the entire device.

[0018] (3) The anti-pressure-injury indwelling needle is provided with a coating, and the coating can be quickly removed from the anti-pressure-injury dressing body when it is needed, thereby improving the convenience of using the entire device. At the same time, the coating can protect the anti-pressure-injury dressing body and ensure that the viscosity of the anti-pressure-injury dressing body will not deteriorate.
