Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a visual upper arm central vein catheterization pressure hemostasis device. Background Art

[0002] Implantable intravenous access ports (VAPs) and peripherally inserted central catheters (PICCs) are two main and relatively safe long-term central venous infusion access routes that can be placed through the upper arm in clinical practice. They are often used for the infusion of anti-tumor drugs and high-concentration, stimulating intravenous nutrition in patients with malignant tumors.

[0003] PICC is performed by puncturing a peripheral vein such as the supracubital basilic vein, median cubital vein or cephalic vein under ultrasound guidance, and inserting the catheter so that the tip reaches the superior vena cava and other large veins close to the heart.

[0004] For upper arm VAP, an incision is made below the puncture point to form a pouch. An injection port is buried under the skin of the upper arm. After connecting it to the catheter, the skin incision is sutured layer by layer and finally a sterile dressing is used.

[0005] Both PICC and upper arm VAP central venous catheterization methods require postoperative pressure and ice treatment on the wound to reduce bleeding, subcutaneous hematoma, bruising, and other problems. In existing clinical techniques, medical personnel usually use elastic bandages or gauze to bandage the puncture point or incision, while applying ice packs. Because single materials such as elastic bandages or gauze cannot effectively and timely observe the skin tissue at the pressure point, when the wound is large, simply using bandages and gauze or loosening the pressure prematurely may not achieve the ideal hemostatic effect. If the bandage or gauze exerts too much pressure and is not released in time, it can easily lead to poor circulation and blood flow to the patient's operated limb, reducing patient comfort. In particular, after upper arm VAP implantation, the non-destructive needle butterfly wings are inserted above the skin surface. Local pressure can easily cause blisters, cyanosis, and subcutaneous edema around the port. Ice compresses that are too low or applied for too long can also cause frostbite on the operated skin. Summary of the Invention

[0006] The purpose of the utility model is to provide a visual upper arm central vein catheterization pressure hemostasis device, which can effectively apply pressure and cold compress while also providing intuitive and visual hemostasis effects.

[0007] To achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: a visual upper arm central venous catheterization pressurized hemostasis device, including a left adhesive area, a middle compression area and a right adhesive area, the middle compression area includes an outer ring transparent air bag and an inner ring transparent water bag, the lower half of the inner ring transparent water bag is provided with a needle-through window, and elastic gaskets are provided around the bottom side of the needle-through window, a first connecting tube and a second connecting tube are connected below the middle compression area, the first connecting tube is connected to the outer ring transparent air bag upward and connected to the inflation head downward, the second connecting tube is connected to the inner ring transparent water bag upward and connected to the water inlet downward.

[0009] Preferably, a Velcro hook surface is provided at the distal end where the left adhesive area is connected to the middle compression area, and a conventional elastic bandage is provided at the proximal end.

[0010] Preferably, the right adhesive area is entirely made of Velcro fleece.

[0011] Preferably, the Velcro fleece surface and the Velcro hook surface are not on the same surface, and the Velcro fleece surface and the Velcro hook surface are connected to form a sleeve shape.

[0012] Preferably, the inner circle transparent water bag is located inside the outer circle transparent air bag, the front view cross section of the inner circle transparent water bag is trapezoidal, and the front view cross section of the outer circle transparent water bag is two left and right triangles.

[0013] Preferably, the front cross-section of the needle-through window is rectangular.

[0014] Preferably, the upper ends of the first connecting tube and the second connecting tube are contained in a connecting tube main channel and bifurcate at the end of the connecting tube main channel, and the connecting tube main channel and the first connecting tube and the second connecting tube form an inverted Y shape.

[0015] Preferably, a flow-stop clamp is sleeved on the surface of the second connecting pipe, and the flow-stop clamp is made of plastic material.

[0016] Preferably, a sealing cover is fixedly connected to the end of the water injection port, and the sealing cover is T-shaped, and the outer diameter of the bottom of the T-shape is adapted to the inner diameter of the lumen of the second connecting pipe.

[0017] The utility model provides a visual upper arm central vein catheterization pressure hemostasis device with the following beneficial effects:

[0018] 1. The utility model adopts a bandage-type elastic Velcro, which has the two advantages of elasticity and self-adhesion. After the pipeline is placed, it is pressurized and fixed by the elastic Velcro. The size of the bandage can be adjusted according to the actual arm circumference of the patient. At the same time, the pressure intensity can be adjusted according to the hemostasis situation of the wound, thereby increasing the comfort of the patient.

[0019] 2. The transparent water bags in this invention are all made of elastic and transparent materials, and the bleeding situation of the wound can be observed at any time.

[0020] 3. The inner transparent water bag in the utility model can be filled with ice water of appropriate temperature to apply cold compress to the wound to stop bleeding, avoiding frostbite of skin tissue by directly using ice cubes. At the same time, the inflated water bag can play a pressing role to stop bleeding faster.

[0021] 4. After the outer transparent air bag of the present invention is inflated, it can exert a squeezing force toward the middle and downward on the inner transparent water bag, which can further assist the compression and hemostasis effect of the transparent water bag.

[0022] 5. The cross-section of the inner transparent water bag in the present invention is trapezoidal when viewed from the front, which can prevent the gas in the outer transparent air bag from liquefying and adhering to the inner wall of the air bag due to the cold water temperature being lower than the room temperature, thereby affecting the observation field of the compression hemostasis area.

[0023] 6. In the present invention, a needle-penetrating window is provided in the lower half of the inner transparent water bag. After the upper arm VAP is implanted, the non-destructive needle inserted can avoid pressure through the needle-penetrating window, thus avoiding local pressure damage.

[0024] 7. The outer periphery of the needle-penetrating window in the present invention is provided with an elastic gasket, which can be in the form of an air ring, and can play a certain buffering role in the pressure difference between the needle-penetrating window and the transparent water bag as a whole.

[0025] 8. The sealing cover and the stop clamp in the present invention can provide double protection against water leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See also Figure 1The utility model provides a visual upper arm central vein catheterization pressurized hemostasis device, comprising a left adhesive area 1, a middle compression area 2 and a right adhesive area 3. The left adhesive area 1 is sutured to the middle compression area 2 and the right adhesive area 3 in sequence. The middle compression area 2 comprises an outer ring transparent air bag 4 and an inner ring transparent water bag 5. The lower half of the inner ring transparent water bag 5 is provided with a needle-through window 6, and the bottom side of the needle-through window 6 is surrounded by elastic gaskets 7. The middle compression area 2 is connected to a connecting tube main channel 8 below. The connecting tube main channel 8 contains a first connecting tube 9 and a second connecting tube 10. The end of the first connecting tube 9 is connected to an inflation head 11, and the end of the second connecting tube 10 is a water inlet 12, which is connected to a sealing cover 14 and a flow-stop clamp 13 is sleeved on the surface.

[0034] In this embodiment, the left adhesive area 1 and the right adhesive area 3 are respectively provided with an elastic Velcro hook surface and an elastic Velcro fleece surface, which are connected to both sides of the middle compression area 2 to form the main body of the device. The middle compression area 2 includes an outer ring transparent air bag 4 and an inner ring transparent water bag 5. After being inflated and / or filled with water, both can play a role in compressing and stopping bleeding at the wound, and the current wound hemostasis situation can also be observed at any time. A needle-through window 6 is provided on the lower half of the inner ring transparent water bag 5 to avoid compression on the butterfly wing of the VAP non-destructive needle. Elastic gaskets 7 are provided around the bottom side of the needle-through window 6 to The pressure difference between the needle window 6 and the inner circle transparent water bag 5 plays a buffering role. The water injection port 12 can be used to inject ice water into the transparent water bag through the second connecting tube 10 to achieve the purpose of cold compressing the wound. After the ice water is injected, the end sealing cover 14 and the stop clamp 13 of the outer jacket are closed to prevent liquid leakage. According to the actual situation of the patient's compression hemostasis requirements, the inflation head 11 can be used to inflate the outer circle transparent air bag 4 through the first connecting tube 9, which exerts an extrusion force toward the middle and downward on the inner circle transparent water bag 5, which can further assist the compression hemostasis effect of the inner circle transparent water bag 5.

[0035] Specifically, the left adhesive area 1 and the right adhesive area 3 are both made of elastic bandage material. The distal 1 / 2 area of ​​the left adhesive area 1 is provided with a Velcro hook surface 101, the proximal 1 / 2 is a conventional elastic bandage 102, and the entire area of ​​the right adhesive area 3 is a Velcro fleece surface.

[0036] In this embodiment, only 1 / 2 of the left adhesive area 1 is made of a hook surface, which lacks elasticity. The remaining 1 / 2 and the right adhesive area 3 are made of an elastic bandage material with a fleece surface, which fully ensures the elasticity of the device and allows for adjustment of pressure based on the patient's actual arm circumference and wound bleeding.

[0037] Specifically, the outer transparent air bag 4 and the inner transparent water bag 5 of the middle compression zone 2 are both made of elastic transparent material.

[0038] In this embodiment, the inner transparent water bag 5 and the outer transparent air bag 4 are both made of elastic transparent materials, so that the hemostasis of the wound can be observed at any time.

[0039] Specifically, the inner circle transparent water bag 5 can be filled with water through the water filling port 12 of the first connecting pipe 10, and the sealing cover 14 and the flow-stop clamp 13 are closed after the water filling is completed.

[0040] In this embodiment, for wounds that require both compression and cold compress to stop bleeding, ice water at a certain temperature can be injected to avoid frostbite that may be caused by direct contact of the skin with ice cubes. Double sealing after water injection can prevent water leakage.

[0041] For details, please refer to Figure 2 The inner transparent water bag 5 is located in the outer transparent air bag 4. The front cross section of the inner transparent water bag is a trapezoid, and the front cross section of the outer transparent water bag is two left and right triangles.

[0042] In this embodiment: after the outer ring transparent air bag 4 is inflated, it can exert a squeezing force toward the middle and downward on the inner ring transparent water bag 5, which can further assist the compression and hemostasis effect of the inner ring transparent water bag 5. At the same time, the outer ring transparent air bag 4 and the inner ring transparent water bag 5 only do not overlap in the outer circle of the surface, which can avoid the gas in the outer ring transparent air bag 4 liquefying and adhering to the inner wall of the outer ring transparent air bag 4 due to the temperature of the inner ring transparent water bag 5 being lower than the indoor temperature, thereby affecting the observation field of the compression and hemostasis area.

[0043] For details, please refer to Figure 3 A needle-penetrating window 6 is provided on the lower half of the inner transparent water bag 5 . The front cross-section of the needle-penetrating window 6 is rectangular. Elastic washers 7 are provided on four circles on the bottom side of the needle-penetrating window 6 .

[0044] In this embodiment, for patients with upper arm VAP implants, the butterfly wings of the intact needle inserted postoperatively can escape through the needle window 6, thereby preventing friction and pressure between the butterfly wings protruding from the skin surface and the base. The four elastic gaskets 7 surrounding the needle window 6 are in the form of air rings, which can provide a certain degree of cushioning for the pressure difference between the needle window 6 and the inner transparent water bag 5. For patients with PICC implants, the purpose of this needle window 6 is negligible.

[0045] The working process of the present invention is as follows: if the patient is implanted with an upper arm VAP, first align the needle-penetrating window 6 on the inner circle transparent water bag 5 with the butterfly wing of the intact needle. If the patient is implanted with a needle-free catheter such as a PICC, the middle point of the inner circle transparent water bag 5 is aligned with the puncture point. The rest of the steps are the same as follows: lay the device flat on the patient's upper arm, wrap it with an elastic bandage according to the patient's upper arm circumference, wound condition and coagulation function, use the elastic Velcro of the left adhesive area 1 and the right adhesive area 3 to connect end to end to form initial compression, use the water inlet 12 through the first The second connecting tube 10 can be used to inject ice water of a certain temperature into the transparent water bag to apply a cold compress to the wound. (For wounds that do not require a cold compress, room temperature liquid can be injected into the inner transparent water bag 5 to simply provide a compressive effect.) After the ice water is injected, the end sealing cap 14 and the stop clamp 13 of the outer outer sleeve are closed to prevent liquid leakage. Depending on the patient's actual need for compression and hemostasis, the inflator head 11 can be used to inflate the outer transparent air bag 4 through the first connecting tube 9, exerting a compressive force toward the center and downward on the inner transparent water bag 5, further assisting the compression and hemostasis effect of the inner transparent water bag 5. During the cold compress and hemostasis process, the outer transparent air bag 4 and the inner transparent water bag 5 allow the wound's hemostasis to be monitored at any time. If the wound is bleeding, oozing, or experiencing subcutaneous hematoma or bruising, or if the skin at the cold compress site is frozen red, or if there is poor circulation or blood flow to the upper limb, the elastic bandage pressure and water temperature can be adjusted promptly to achieve effective compression and cold compress hemostasis.

[0046] The above is only a specific implementation method of the utility model, but the scope of protection of the utility model is not limited to this. Any changes or replacements that can be easily thought of by technicians familiar with the field within the technical scope disclosed in the utility model should be covered by the scope of protection of the utility model.
