Description

Technical Field

[0001] The utility model relates to the technical field of PICC protective sleeves, in particular to a PICC protective sleeve with a pressurizing function. Background Art

[0002] PICC protective cover is a medical device specially used to protect the peripherally inserted central catheter (PICC). Its main functions include fixing and protecting the PICC catheter to prevent it from moving, falling off or being damaged by external friction, impact, compression, etc., thereby avoiding unnecessary harm to the patient.

[0003] PICC protective covers are usually made of silicone or other soft, breathable materials that fit tightly on the arm and cover the PICC catheter site. To ensure its fixation and protection, the protective cover should be of the right size and replaced regularly to avoid the risk of bacterial growth and infection.

[0004] The current PICC protective covers only provide physical protection. When the patient moves, muscle peristalsis can cause the venous catheter to move, which in turn causes bleeding at the puncture point. The existing PICC protective covers cannot prevent or alleviate the bleeding. Summary of the invention

[0005] Technical issues solved

[0006] In view of the deficiencies in the prior art, the utility model provides a PICC protective cover with a pressurizing function to solve the problems in the background technology.

[0007] In order to solve the above problems, the utility model provides the following technical solutions:

[0008] A PICC protective sleeve with a pressurizing function comprises a sleeve bag, which is arranged to be through-connected front and back, with sleeves installed at two bag openings of the sleeve, the inner diameter of the sleeve is smaller than the inner diameter of the sleeve, a connector is installed at the middle position of the sleeve, an air intake valve pipe is threadedly connected at the connector position, a branch pipe is connected to the air intake valve pipe, a valve plate 2 and a valve plate 1 are installed at the middle position of the branch pipe and the middle lower position of the air intake valve pipe respectively through glue points, a connecting pipe is sleeved at the top opening of the air intake valve pipe, and a balloon is connected to the end of the connecting pipe.

[0009] Preferably, the branch pipe and the inner wall of the intake valve pipe are installed with limit stop rings corresponding to the valve plate two and valve plate one positions, the limit stop ring at the valve plate one position is located above the valve plate one, the limit stop ring at the valve plate two position is located on the front side of the valve plate two, and the side surfaces of the valve plate two and the valve plate one abut against the limit stop rings at the corresponding positions to form a seal.

[0010] Preferably, the end of the branch pipe is threadedly connected with a plugging cap.

[0011] Preferably, a strap is wrapped around the outer periphery of the sleeve, and Velcro is connected to the strap.

[0012] Preferably, a retractable belt made of elastic rubber material is installed on the outer periphery of the sleeve near the bagging position.

[0013] Preferably, a support seat is installed at the position of the elastic band corresponding to the outer periphery of the sleeve, the top surface of the support seat is arranged in an inwardly concave arc structure, and the elastic band is wound around the arc-shaped top surface of the support seat.

[0014] Compared with the prior art, the utility model provides a PICC protective cover with a pressurizing function, which has the following beneficial effects:

[0015] 1. The PICC protective cover is provided with a balloon and a connecting tube, and an air inlet valve tube is used for connecting and supplying air. When the balloon is squeezed and released back and forth, air can be inflated into the bag, and the inside is pressurized to form a pressurized state with a higher pressure than the outside.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0025] See also Figure 1-5 A PICC protective sleeve with a pressurizing function comprises a sleeve 1, which is arranged to be connected from front to back, and sleeves 2 are integrally formed and installed at the two bag openings of the sleeve 1, and the inner diameter of the sleeve 2 is smaller than the inner diameter of the sleeve 1, and a connector 3 is hot-melt installed at the middle position of the sleeve 1, and an air intake valve pipe 6 is threadedly connected at the connector 3, the air intake valve pipe 6 is an external thread, and the connector 3 is an internal thread, the air intake valve pipe 6 is connected to the inside of the sleeve 1, and a valve plate 7 is provided at the lower middle position of the air intake valve pipe 6, and the valve plate 7 is hot-melt fixed to the inner wall of the air intake valve pipe 6 through a glue point 16;

[0026] The intake valve pipe 6 above the valve plate 1 7 is integrally formed with a branch pipe 9, a valve plate 2 10 is arranged in the middle of the branch pipe 9, and the valve plate 2 10 is also fixed to the inner wall of the branch pipe 9 by hot melting through the glue points 16 at the corresponding positions, the valve plate 1 7 and the valve plate 2 10 are both made of silicone material, and the branch pipe 9 and the inner wall of the intake valve pipe 6 corresponding to the valve plate 2 10 and the valve plate 1 7 are hot-melted and installed with a limit retaining ring 8, wherein the limit retaining ring 8 at the position of the valve plate 1 7 is located above the valve plate 1 7, and the limit retaining ring 8 at the position of the valve plate 2 10 is located in front of the valve plate 2 10, and the valve plate 2 10 and the side of the valve plate 1 7 abut against the limit retaining ring 8 at the corresponding position to form a seal;

[0027] A connecting tube 12 is sleeved on the top position of the intake valve tube 6, and the end of the connecting tube 12 away from the intake valve tube 6 is integrally connected with a balloon 13. The balloon 13 and the connecting tube 12 are made of silicone rubber material. The balloon 13, the connecting tube 12, and the intake valve tube 6 are internally connected, and the end of the branch pipe 9 away from the intake valve tube 6 is threadedly connected with a blocking cap 11.

[0028] When in use, the bag 1 is put on the patient's arm, the intravenous catheter is located on the inside of the bag 1, the cuff 2 is close to the patient's skin to form a seal, and then the blocking cap 11 is removed, the balloon 13 is pinched and then relaxed. When pinching the balloon 13, the internal air is squeezed to increase the internal air pressure, and the air pressure pushes the valve plate 17 to open and allow air to enter the bag 1. When released, the air pressure pushes the valve plate 17 to close against the limit baffle ring 8. At this time, the internal pressure is pressed, and the external air pressure pushes the valve plate 2 10 to open inward, and the external air enters the connecting tube 12 and the balloon 13. Pinch the balloon 13 again, and the internal air enters the bag 1 again. The balloon 13 is pinched in a reciprocating cycle, and then relaxed and pinched again, and the bag 1 can be inflated to make the internal pressure greater than the external pressure, forming a pressurized state inside. The pressurized state can alleviate the bleeding caused by the intravenous catheter when the patient is active. When taking it off or decompressing, unscrew the air inlet valve pipe 6 to deflate.

[0029] In this embodiment, a binding belt 4 is wound around the outer circumference of the sleeve 2, and a Velcro 5 is sewn on the binding belt 4.

[0030] After wearing and before applying pressurization, use the strap 4 to tie the position of the cuff 2 and fix it with Velcro 5 to bind the position of the cuff 2 to avoid the situation where the internal pressure is greater than the external pressure, causing the cuff 2 to be opened and connected to the outside, resulting in pressure balance and pressurization failure.

[0031] In this embodiment, a retractable belt 15 is installed at the outer periphery of the sleeve 2 near the bag 1, and the retractable belt 15 is made of elastic rubber material.

[0032] The elastic band 15 is used to increase the tightening effect on the basis of the cuff 2. When the pressure is not high and the cuff 2 and the elastic band 15 are sufficient to provide binding and sealing, the strap 4 is not used. When the pressure is high and the tightening force provided by the cuff 2 and the elastic band 15 is not enough to provide a reliable seal, the strap 4 is used.

[0033] In this embodiment, a support seat 14 is integrally formed and installed at the outer periphery of the sleeve 2 corresponding to the position of the retractable belt 15 . The top surface of the support seat 14 is an inwardly concave arc structure, and the retractable belt 15 is wound around the arc-shaped top surface of the support seat 14 .

[0034] The support seat 14 increases the contact surface between the elastic band 15 and the skin, thereby reducing the local pressure and alleviating the generation of pressure sore marks.
