Description

PICC fixture

technical field

The utility model relates to the field of medical equipment, in particular to a PICC fixing device.

Background technique

PICC is a catheter inserted into the central vein through antecubital peripheral venipuncture, which can be left in place for a long time for intravenous infusion and blood transfusion therapy. During the indwelling period, there is no need to puncture the skin for each infusion, just directly pierce the needle into the heparin cap at the end of the catheter, and flush the catheter with normal saline. When there is no infusion, the nurse needs to complete the maintenance of the catheter every week and replace the patch, so as to completely It solves the pain caused by puncture and drug stimulation, is safer and more comfortable to carry, and can easily complete the whole treatment process, fundamentally improving the quality of life of patients.

While PICC is beneficial to patients, it also has the following disadvantages: 1) Because it needs to be worn for a long time, it may be taken off due to undressing and other reasons, and it is easy for people who are unconscious or restless to take off the tube. PICC belts are commonly used in clinical practice for simple fixation of irregular items such as elastic bandages and stockings. If the elastic bandage is too loose, it will not be able to fix it, and it will easily cause the catheter to detach; 2) during use, the heparin cap and the like are easy to swing, thereby scratching the patient's arm.

Utility model content

In view of this, the purpose of the utility model is to provide a PICC fixing device, which can effectively fix the PICC catheter.

The utility model solves the above problems through the following technical means: a PICC fixing device, including a bandage made of elastic material, a base plate is arranged on one side of the bandage, a pressure block is arranged under the bandage, and an air bag is arranged on the bottom surface of the pressure block The pad also includes an inflation structure communicated with the airbag cushion and an adjustment structure that drives the pressure block to move horizontally. The adjustment structure includes a lead screw and a guide rod arranged side by side, and one end of the lead screw passes through the pressure block and is threadedly connected with the pressure block , the other end passes through the base plate and is rotatably connected with the base plate, one end of the guide rod is connected with the base plate, and the other end passes through the pressing block and is slidably connected with the pressing block.

Further, the bottom surface of the pressing block is an arc-shaped surface.

Further, arc-shaped grooves are provided on the bottom of the substrate.

Beneficial effects of the present utility model: the PICC fixing device of the present utility model includes a bandage made of elastic material, a base plate is arranged on one side of the bandage, a pressing block is arranged under the bandage, and an airbag cushion is arranged on the bottom surface of the pressing block, It also includes an inflation structure communicated with the airbag cushion and an adjustment structure that drives the pressure block to move horizontally. The adjustment structure includes a lead screw and a guide rod arranged side by side. One end of the lead screw passes through the pressure block and is threadedly connected with the pressure block. One end passes through the base plate and is rotatably connected with the base plate, one end of the guide rod is connected with the base plate, and the other end passes through the pressing block and is slidably connected with the pressing block. The PICC fixing device with this structure can reliably and effectively fix the PICC catheter.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is the structural representation of the utility model.

detailed description

The utility model will be described in detail below in conjunction with accompanying drawing, as shown in Figure 1: a kind of PICC fixture, comprises the bandage 1 that is made of elastic material, described bandage one side is provided with substrate 2, and described substrate bottom is provided with The arc-shaped groove 8, the arc-shaped groove is clamped with the patient's arm, the pressure block 3 is arranged under the bandage, the air bag cushion 4 is arranged on the bottom surface of the pressure block, and the inflatable structure 5 communicated with the air bag cushion and the device for driving the pressure block to move horizontally are also included. An adjustment structure, the adjustment structure includes a lead screw 6 and a guide rod 7 arranged side by side, one end of the lead screw passes through the briquetting block and is threadedly connected with the briquetting block, and the other end passes through the base plate and is rotatably connected with the base plate, the guide rod One end is connected with the base plate, and the other end passes through the pressing block and is slidably connected with the pressing block. When in use, first turn the lead screw to fine-tune the position of the pressure block in the horizontal direction, so that the PICC catheter is between the airbag cushion and the arm, and the PICC catheter is fixed for the first time by tightening the bandage, and finally through inflation The structure fills the airbag cushion with suitable gas to realize the compression and fixation of the PICC catheter again. To sum up, the structured PICC fixation device can reliably and effectively fix the PICC catheter.

As a further improvement of the above technical solution, the bottom surface of the pressing block is an arc-shaped surface, and the airbag cushion is bonded to the arc-shaped surface. The airbag cushion is also in an arc shape, which facilitates better compression of the PICC catheter.

Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present utility model without limitation. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the utility model can be Modifications or equivalent replacements of the technical solutions without departing from the purpose and scope of the technical solutions of the utility model shall be covered by the claims of the utility model.
