Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a PICC cuff which is convenient for observation. Background Art

[0002] PICC stands for "Peripherally Inserted Central Catheter". PICC is suitable for patients who receive long-term intravenous medication, antibiotics or highly irritating drugs, chemotherapy drugs, pain control drugs and total parenteral nutrition, patients whose conditions are unstable and who need to take medication or measure central venous pressure at any time. The common clinical PICC fixation method is to fix the catheter with a film and then wear an elastic cuff to wrap and fix the PICC catheter. The puncture site cannot be exposed and the extension tube cannot be well fixed, which makes it inconvenient for clinical nursing staff to observe the maintenance and fixation of the catheter.

[0003] Among them, the PICC tube protective cover disclosed in application number CN202020941365.5 is also an increasingly mature technology. By tightening the elastic band and tightening the opening of the waterproof cover, water is blocked from flowing into the part covered by the waterproof cover, so that the PICC tube is separated from the water flow and the PICC tube body is prevented from being immersed in water.

[0004] A PICC catheter protective sleeve disclosed in CN202221970265.0 is an increasingly mature technology. The hard connector at the end of the PICC catheter is arranged on the outside of the wrapping band, and the wrapping band is in contact with the patient's skin, which effectively solves the problem of long-term squeezing contact between the hard connector at the end of the PICC catheter and the patient's skin, causing pressure injuries to the skin.

[0005] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0006] When the patient wears the two protective sleeves, the catheter may accidentally fall off without the medical staff being aware of it, and the medical staff is also unable to know whether the patient feels any discomfort during the intravenous injection. Utility Model Content

[0007] The utility model aims to provide a PICC cuff which is easy to observe, so as to solve the problem in the above background technology that medical staff cannot know whether the catheter falls off and whether the patient feels discomfort during intravenous injection.

[0008] The utility model embodiment provides a PICC cuff which is easy to observe, comprising a cuff inner layer, a magic adhesive surface is sewn and connected to the outer side of the cuff inner layer, the outer layer of the cuff is adhered to the outer side of the magic adhesive surface, a window line is provided in the middle of the cuff inner layer opposite to the magic adhesive surface, a plurality of through holes for infusion straps to enter and exit are provided on the surface of the window line, a plurality of straight brackets are connected to one side wall of the window line, a line cover is sewn to one side wall of the window line away from the straight bracket, a plurality of discs are connected to one side wall of the line cover, the straight brackets are buckled and connected to the discs, a magnet is provided on the outer side of one side of the window line located on the straight bracket, a pressure sensor is provided on the line cover at a position corresponding to the magnet, and an alarm is provided on the side of the cuff inner layer located on the side of the window line.

[0009] In this embodiment, through the signal connection between the pressure sensor and the alarm, when the pressure sensor is separated from the magnet, the alarm will promptly sound an alarm, and the medical staff can promptly stop the patient from forcibly removing the tube and take rescue measures, which can also prevent the catheter from falling off. The medical staff inserts the catheter into the patient's arm through the through hole, and then buckles the disc in the bracket to stably fix the catheter.

[0010] In one embodiment of the utility model, a scale tape is pasted between the inner layer and the outer layer of the sleeve, a sub-buckle is arranged on the outside of one end of the scale tape, and a female buckle is arranged on the end of the scale tape away from the sub-buckle, and the sub-buckle is buckled and connected with the female buckle.

[0011] In this solution, the arm circumference is read through the scale tape, and the value is compared with the previous value to confirm whether the patient feels any discomfort from the intravenous injection and whether there is any obvious swelling in the arm circumference. After the measurement is completed, the sub-buckle of the scale tape can be connected with the main buckle to avoid loss of the scale tape.

[0012] In an implementation manner of the utility model, adjustable elastic bands are sewn inside both ends of the inner layer of the sleeve, and water-absorbing cotton rings are arranged on the inner side walls at both ends of the inner layer of the sleeve.

[0013] In this solution, the tightness of the inner layer of the sleeve can be adjusted by adjusting the comfort of the inner layer of the sleeve according to the patient's needs, and the absorbent cotton ring can help absorb moisture inside the inner layer of the sleeve.

[0014] In an implementation manner of the utility model, a pipeline clamp is provided at the bottom end of the inner layer of the sleeve located at the line cover, and an elastic band is provided at the bottom end of the pipeline clamp.

[0015] In this solution, the pipeline clamp and the elastic band cooperate to facilitate clamping the catheter in the pipeline clamp, and then place the connector end of the catheter inside the elastic band to avoid contamination of the catheter connector end.

[0016] In one embodiment of the utility model, the inner side wall of the outer layer of the sleeve is sewn with a magic fleece surface, and the first zipper strip and the second zipper strip are sewn on both sides of the outer layer of the sleeve respectively, and the bottom end of the first zipper strip is provided with a zipper for opening and closing connection.

[0017] In this solution, the first zipper strip and the second zipper strip are meshed and connected with each other through a zipper, so that medical staff can easily open or close the outer layer of the sleeve.

[0018] In one implementation of the utility model, the outer layer of the sleeve is provided with an observation window, the outer layer of the sleeve is made of waterproof material, and the window lines and line covers are both made of transparent materials.

[0019] In this solution, the window lines and the line cover are both made of transparent materials, which can provide a clear field of vision, making the observation window of the outer layer of the sleeve more clear and visible. The outer layer of the sleeve is made of waterproof material, which can effectively prevent moisture from penetrating into the inner part of the outer layer of the sleeve.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. Through the signal connection between the pressure sensor and the alarm, when the pressure sensor of the line cover is separated from the magnet of the window line, the power signal is transmitted to the alarm, and the alarm sounds in time. Medical staff can stop the patient from forcibly removing the tube in time, take rescue measures, and prevent the catheter from falling off;

[0022] 2. The elastic bands at both ends of the inner layer of the cuff can be used to adjust the tightness of the inner layer of the cuff according to the patient's needs to ensure that the inner layer of the cuff is fastened and stable without being too tight. The absorbent cotton ring can help absorb the moisture inside the inner layer of the cuff and keep the PICC site dry to reduce the risk of infection. The medical staff inserts the catheter into the patient's arm through the through hole, and then buckles the line cover in the bracket on one side wall of the window line to fix the catheter stably. The arm circumference value is read through the scale tape, and the value is compared with the previous value to confirm whether the patient has any discomfort during intravenous injection and whether the arm circumference is obviously swollen. After the measurement, the sub-buckle of the scale tape can be buckled and connected with the main buckle to avoid the risk of losing the scale tape. BRIEF DESCRIPTION OF THE DRAWINGS
