Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a PICC tube fixing device. Background Art

[0002] Peripherally Inserted Central Venous Catheters (PICC) are catheters inserted through punctures in peripheral veins (e.g., basilic vein, median cubital vein, cephalic vein). The tip of the central venous catheter is located inside the human vein, and the end of the central venous catheter is led out from the front of the upper arm.

[0003] When patients use central venous catheters for drug infusion treatment, due to the long drug infusion time, they are prone to arm stiffness, numbness and other discomfort symptoms. In addition, for patients who can move freely, turning over, sitting up and other actions are likely to cause the cannula to move, affecting the treatment effect and increasing the burden on medical staff. At present, the PICC tube is mostly fixed by medical tape. When external force pulls or the patient sweats, the stickiness of the tape decreases and the fixing effect becomes worse. In addition, it is easy to cause pain to the patient when the medical tape is torn off.

[0004] Therefore, in clinical situations where a peripherally inserted central catheter is required for treatment, a PICC tube fixing device is needed to fix the portion of the PICC tube that is left outside the body to ensure the treatment effect. Utility Model Content

[0037] Example 1

[0038] A specific embodiment of the utility model discloses a PICC tube fixing device, which is used to fix the PICC tube during central venous cannulation of the arm. Figure 1 , Figure 2 As shown, the PICC tube fixing device of this embodiment includes: an upper clamp 1, a lower clamp 4 and an intermediate bridge plate 6; the upper clamp 1 and the lower clamp 4 can be tightened on the patient's arm, and are respectively located on the upper and lower sides of the PICC tube puncture point; the intermediate bridge plate 6 is connected between the upper clamp 1 and the lower clamp 4; a positioning clamp 5 is provided on the inner side of the lower clamp 4, and the positioning clamp 5 is a semi-enclosed annular structure, which can be clamped on the outer side of the PICC tube for positioning the PICC tube; a pressurizing component is also provided on the inner side of the upper clamp 1; the pressurizing component expands after being inflated to squeeze the patient's arm.

[0039] In the utility model, the PICC tube is fixed by the positioning clamp 5 to prevent the lower clamp 4 from affecting the normal flow of the liquid in the PICC tube when it is clamped; at the same time, the upper clamp 1 and the lower clamp 4 are used to clamp and position the patient's arm, which can effectively prevent the PICC tube from loosening or falling off; in the utility model, a pressurizing component that expands after inflation is also provided, which can repeatedly press the patient's arm, promote blood circulation and relieve the patient's fatigue.

[0040] In a specific implementation of the utility model, Figure 1 As shown, the pressurizing assembly and the upper clamp 1 are an integrated structure.

[0041] Furthermore, the pressurizing component is a first inflatable airbag 7, which is arranged on the inner wall surface of the upper clamp 1 and is connected to the air storage airbag 9 through an air guide tube 8; when the air storage airbag 9 is squeezed, its internal gas can be pressed into the first inflatable airbag 7, and the first inflatable airbag 7 expands after being inflated.

[0042] like Figure 1 , Figure 2 As shown, the first inflatable airbag 7 is nested on the first arc-shaped hoop plate 101 and the second arc-shaped hoop plate 102 of the upper hoop 1 .

[0043] Preferably, a plurality of first inflatable airbags 7 are provided, and the plurality of first inflatable airbags 7 are connected through a connecting pipe embedded in the upper clamp 1. The air guide pipe 8 passes through the back side of the upper clamp 1 and is connected to the connecting pipe. When the air storage airbag 9 is squeezed, the gas in the air storage airbag 9 enters the first inflatable airbag 7 through the air guide pipe 8 and the connecting pipe, causing the first inflatable airbag 7 to expand.

[0044] Specifically, the air storage bag 9, the air guide pipe 8 and the connecting pipe are all made of non-elastic soft plastic material.

[0045] Preferably, the first inflatable airbag 7 is made of soft rubber or elastic rubber. After being inflated, the first inflatable airbag 7 recovers from a compressed state to an inflated state, or the first inflatable airbag 7 expands in volume after elastic deformation.

[0046] In a specific embodiment of the utility model, the upper hoop 1 includes: a first arc-shaped hoop plate 101, a second arc-shaped hoop plate 102, an elastic band 103, a first adhesive band 2 and a second adhesive band 3; the elastic band 103 is connected between the first arc-shaped hoop plate 101 and the second arc-shaped hoop plate 102, and the elastic band 103 is a retractable elastic material; the ends of the first arc-shaped hoop plate 101 and the second arc-shaped hoop plate 102 are respectively connected to the first adhesive band 2 and the second adhesive band 3; the first adhesive band 2 and the second adhesive band 3 can be bonded and fixed to each other, and after the two are connected, the upper hoop 1 can be tightened on the upper side of the patient's arm.

[0047] Specifically, the first arc-shaped hoop plate 101 and the second arc-shaped hoop plate 102 are made of non-elastic plastic material.

[0048] The upper clamp 1 of the utility model is provided with a first arc-shaped clamp plate 101, a second arc-shaped clamp plate 102 and an elastic band 103 as a supporting structure, which is supported on the back of the patient's arm when in use, and after being tightened, the first arc-shaped clamp plate 101 and the second arc-shaped clamp plate 102 do not completely fit the arm, so that a gap is left between the arm and the upper clamp 1, thereby avoiding the phenomenon of blood circulation in the arm when the upper clamp 1 is tightened.

[0049] The upper clamp 1 of the PICC tube fixing device of the utility model adopts the design of two symmetrical arc-shaped clamp plates and elastic band 103, and is provided with a first adhesive strap 2 and a second adhesive strap 3 as fixed buckles to adapt to patients of different body shapes, and the tightness can be adjusted by oneself, and the patient can be put on and taken off at any time.

[0050] In a specific embodiment of the present invention, the lower hoop 4 adopts the same structure as the upper hoop 1. Alternatively, the lower hoop 4 is an annular adhesive band, and the lower hoop 4 can be clamped on the lower side of the patient's arm by adhesively fixing the two ends of the lower hoop 4.

[0051] Furthermore, at least two intermediate bridge plates 6 are provided; the intermediate bridge plates 6 are hard; or the intermediate bridge plates 6 are made of soft metal, such as aluminum alloy.

[0052] like Figure 1 As shown, the air storage bag 9 is spherical or ellipsoidal.

[0053] In a specific implementation manner of the present invention, the first adhesive tape 2 and the second adhesive tape 3 are Velcro tapes that can be bonded to each other.

[0054] Furthermore, when the lower clamp 4 is a ring-shaped adhesive strap, the middle portion of the lower clamp 4 is an elastic bandage, and both ends are Velcro.

[0055] Specifically, Figure 1 As shown, one end of the lower hoop 4 is the adhesive surface of the outer Velcro, and a positioning clip 5 is fixedly arranged on the back.

[0056] Specifically, in order to prevent the PICC tube from slipping out of the positioning clamp ring 5, the internal through hole of the positioning clamp ring 5 is set to a waist drum-shaped structure with a wide middle and narrow ends. In order to facilitate the clamping and fixing of the positioning clamp ring 5 and the PICC tube, a strip-shaped gap is provided at the lower end of the positioning clamp ring 5 to make it a semi-enclosed structure.

[0057] Preferably, the positioning clamp ring 5 is made of a non-deformable plastic material. After the PICC tube is flattened, it is inserted into the positioning clamp ring 5 through the strip-shaped gap. The PICC tube will not be separated from the positioning clamp ring 5 without being pulled by external force.

[0058] Preferably, in order to enhance the firmness of positioning the PICC tube, medical tape may be used to adhere and fix the positioning clamp ring 5, the PICC tube and the lower clamp 4.

[0059] During implementation, first, clamp the positioning clamp ring 5 on the outside of the PICC tube; then, glue and fix the two ends of the lower clamp 4, so that the lower clamp 4 is clamped on the arm, and the lower clamp 4 is located below the puncture port, and the positioning clamp ring 5 is pressed between the arm and the lower clamp 4; finally, the first arc hoop plate 101 and the second arc hoop plate 102 of the upper clamp 1 are fitted to the back of the patient's upper arm, and the first adhesive band 2 and the second adhesive band 3 are glued and fixed to each other, and at the same time, the upper clamp 1 is clamped on the upper arm, completing the connection between the PICC tube fixing device and the PICC tube and the patient's arm, thereby achieving effective fixation of the PICC tube.

[0060] During intravenous infusion, the air storage bag 9 is squeezed repeatedly to expand or contract the first inflatable bag 7, which can repeatedly press the back of the arm, relieve the patient's fatigue and promote blood circulation in the arm.

[0061] Example 2

[0062] In a specific embodiment of the present invention, Figure 3 , Figure 4 , Figure 5 As shown, the difference from Example 1 is that the pressurizing assembly and the upper clamp 1 are separate structures, and the two are detachably connected.

[0063] Specifically, a detachable air cushion assembly 10 is used as a pressurizing assembly.

[0064] In this embodiment, Figure 5 , Figure 6 As shown, the air cushion assembly 10 includes: an arc-shaped air cushion 1001, a second inflatable airbag 1002, an air guide tube 8 and an air storage airbag 9. A plurality of the second inflatable airbags 1002 are arranged on the upper surface of the arc-shaped air cushion 1001, and are all connected to the internal cavity of the arc-shaped air cushion 1001; the arc-shaped air cushion 1001 is connected to the air storage airbag 9 through the air guide tube 8; when the air storage airbag 9 is squeezed, the internal gas can be pressed into the second inflatable airbag 1002, and the second inflatable airbag 1002 expands after being inflated.

[0065] Specifically, Figure 5 As shown, a plurality of second inflatable airbags 1002 are arranged on the surface of the arc-shaped air cushion 1001, wherein the arc-shaped air cushion 1001 is an arc-shaped structure with an internal cavity, and the plurality of second inflatable airbags 1002 are all connected to the internal cavity of the arc-shaped air cushion 1001, and after pressurization, the plurality of second inflatable airbags 1002 expand synchronously in volume.

[0066] like Figure 5 , Figure 6As shown, two groups of second inflatable airbags 1002 are symmetrically arranged on the surface of the arc-shaped air cushion 1001, with four in each group. Specifically, the second inflatable airbags 1002 are rectangular structures in the initial state, and the surface expands and bulges after being inflated.

[0067] Preferably, the arc-shaped air cushion 1001 and the second inflatable airbag 1002 are both made of flexible materials.

[0068] The arc-shaped air cushion 1001 is made of a non-elastic flexible plastic material, such as polyvinyl chloride and polypropylene; the second inflatable airbag 1002 is made of an elastic rubber material, and the second inflatable airbag 1002 expands after being inflated.

[0069] Furthermore, in order to improve the coordination effect between the arc-shaped air cushion 1001 and the upper clamp 1, a plurality of hemispherical grooves are provided on the surface of the first arc-shaped hoop plate 101 and the second arc-shaped hoop plate 102 of the upper clamp 1, and a hemispherical protrusion (not shown in the figure) is provided at the bottom of the arc-shaped air cushion 1001 accordingly. Through the coordination of the hemispherical protrusion and the hemispherical groove, the arc-shaped air cushion 1001 is positioned on the upper surface of the upper clamp 1 to prevent the relative slippage between the two, so as to facilitate the fixing of the upper clamp 1 on the patient's arm. Preferably, the size of the hemispherical protrusion is smaller than the size of the hemispherical groove.

[0070] During implementation, the arc-shaped air cushion 1001 is placed on the inner side of the upper clamp 1. When the upper clamp 1 is tightened around the outside of the patient's arm, the arc-shaped air cushion 1001 contacts the back of the patient's arm, squeezing the air storage bag 9. The gas in the air storage bag 9 is pressed into the second inflatable air bag 1002, so that the upper surface of the second inflatable air bag 1002 is lifted up to squeeze the back of the arm. The reciprocating pressurization massages the internal muscles of the arm, relieves the patient's fatigue, and promotes blood circulation inside the arm.

[0071] The above is only a preferred specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
