Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a compression hemostasis device for nursing care. Background Technology

[0002] After treatment for cardiovascular diseases, medical staff need to press the puncture site with their fingers. The pressure should not be too high or too low. A compression hemostatic device needs to be used to press the puncture site accurately for a longer period of time, with intermittent buffering release, to ensure the necessary blood supply and avoid the occurrence of high blood pressure.

[0003] Using an airbag for compression hemostasis is a common method, but it still has some problems. First, the airbag has a large contact area with the skin, requiring significant pressure to achieve hemostasis. During prolonged hemostasis, it can easily cause poor blood flow under the skin, leading to numbness, cyanosis, and further swelling due to poor blood pressure. In severe cases, it can even cause nerve damage or arterial occlusion. On the other hand, insufficient compression time or pressure can easily cause oozing, bleeding, or even subcutaneous hematoma. When performing compression hemostasis, medical staff need to operate in pairs: one to apply the fixation strap and the other to inflate the airbag. This results in low work efficiency and requires frequent adjustments to the air pressure inside the airbag for inflation and deflation.

[0004] In view of the shortcomings of existing technology, there is an urgent need for a new type of compression hemostasis device for nursing. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a compression hemostasis device for nursing care to solve the above problems.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a compression hemostasis device for nursing care, comprising a reusable mounting frame and a disposable fixing strap. A limiting protrusion is fixed on the upper side of the mounting frame near the rear edge. A winding cavity is provided in the middle of the mounting frame. The winding cavity has a fan-shaped structure with a diffused opening on the lower side and an opening on the front side. An adjusting shaft is provided inside the winding cavity. The rear end of the adjusting shaft is rotatably connected to the rear side of the mounting frame. The rear end of the adjusting shaft extends out of the mounting frame and is fixed to a driving shaft. A knob is fixed to the rear end of the driving shaft, and a self-locking turntable is fixed in the middle of the driving shaft. The arc-shaped side of the self-locking turntable is serrated. The self-locking turntable is located below the limiting protrusion. A self-locking strip is slidably connected inside the limiting protrusion. The lower side of the self-locking strip has an inwardly concave arc structure and a serrated structure. A push-pull button is fixed on the upper side of the self-locking strip.

[0007] A mounting panel is fixed to the lower side of the mounting bracket near the rear edge. Two limiting pivots are provided at the left and right corners of the mounting panel near the lower edge. The distance between the two limiting pivots is greater than the thickness of the fixing belt. The rear end of the limiting pivot is rotatably connected to the mounting panel. A mounting cross plate is provided between the left and right limiting pivots. A gasket is fixed to the lower side of the mounting cross plate.

[0008] The limiting protrusion has a locking groove inside, and a corresponding limiting groove is provided on the rear side of the locking groove. The self-locking bar has a positioning protrusion fixed on the front side. The positioning protrusion is a V-shaped structure with a forward protrusion in the middle. A locking rod is slidably connected in the locking groove. The rear end of the locking rod is inserted into the limiting groove. The upper and lower sides of the locking rod near the rear end are both inclined, making the rear end of the locking rod V-shaped. A spring is provided in the locking groove. One end of the spring contacts the front side of the locking groove, and the rear end of the spring contacts the front end of the locking rod.

[0009] Preferably, a pressure block is fixed in the middle of the fixing band, and limit protrusions are fixed at both ends of the fixing band. The limit protrusions are T-shaped structures with the same cross-section as the limit T-groove.

[0010] Preferably, the fixing strap is made of transparent soft plastic sheet or soft plastic film, and the thickness of the fixing strap is between 0.01mm and 1mm.

[0011] Preferably, the adjusting shaft is provided with two symmetrically arranged limiting T-shaped grooves.

[0012] Preferably, the gasket is made of a flexible material such as rubber or silicone.

[0013] The beneficial effects of this invention are as follows: This invention uses disposable protective patches attached to the pads, preventing the reusable pads from directly contacting the patient and causing infection. A knob rotates the shaft, which in turn rotates the adjusting shaft to wind up the fixing belt until the pressure block is applied to the patient, completing pressure hemostasis. This can be operated by a single person, reducing the workload of medical staff. A self-locking clip contacts the serrated part on the side of the self-locking disc to lock the self-locking clip, ensuring the adjusting shaft is securely locked. Adjusting the winding of the fixing belt by adjusting the shaft adjusts the tightness of the fixing belt, thereby adjusting the pressure for pressure hemostasis, ensuring effective pressure hemostasis while avoiding patient discomfort.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0019] like Figure 1-3 As shown, a compression hemostatic device for nursing use includes a reusable mounting frame 1 and a disposable fixing strap 2. A limiting protrusion 3 is fixed to the upper side of the mounting frame 1 near its rear edge. A winding cavity 101 is provided in the middle of the mounting frame 1. The winding cavity 101 has a fan-shaped structure with a diffused opening on the lower side and an opening on the front side. An adjusting shaft 4 is provided inside the winding cavity 101. The rear end of the adjusting shaft 4 is rotatably connected to the rear side of the mounting frame 1, and the rear end of the adjusting shaft 4 extends out of the mounting frame 1. The frame 1 is fixed with a drive shaft 5. A knob 7 is fixed at the rear end of the drive shaft 5. A self-locking turntable 6 is fixed in the middle of the drive shaft 5. The arc-shaped side of the self-locking turntable 6 is serrated. The self-locking turntable 6 is located below the limiting protrusion 3. A self-locking strip 8 is slidably connected inside the limiting protrusion 3. The lower side of the self-locking strip 8 is a concave arc structure and has a serrated structure, which makes it easy to fit completely with the arc-shaped side of the self-locking turntable 6 and limit the position of the self-locking turntable 6. A push-pull button 9 is fixed on the upper side of the self-locking strip 8.

[0020] In this embodiment, a mounting panel 10 is fixed on the lower side of the mounting bracket 1 near the rear edge. Two limiting pivots 11 are provided on the left and right corners of the mounting panel 10 near the lower edge. The distance between the two limiting pivots 11 is greater than the thickness of the fixing strap 2, so that the fixing strap 2 can pass through. The rear end of the limiting pivot 11 is rotatably connected to the mounting panel 10. A mounting cross plate 12 is provided between the limiting pivots 11 on the left and right sides. A gasket 13 is fixed on the lower side of the mounting cross plate 12.

[0021] In this embodiment, a locking groove 301 is provided inside the limiting protrusion 3, and a limiting groove 302 is provided on the rear side of the locking groove 301. A positioning protrusion 801 is fixed on the front side of the self-locking strip 8. The positioning protrusion 801 is a V-shaped structure with a forward protrusion in the middle. A locking rod 16 is slidably connected in the locking groove 301. The rear end of the locking rod 16 is inserted into the limiting groove 302. The upper and lower sides of the locking rod 16 near the rear end are both inclined, so that the rear end of the locking rod 16 is V-shaped. This facilitates the generation of a horizontal component force after the rear end of the locking rod 16 contacts the side of the positioning protrusion 801, so that the locking rod 16 slides relative to the positioning protrusion 801. A spring 17 is provided in the locking groove 301. One end of the spring 17 contacts the front side of the locking groove 301, and the rear end of the spring 17 contacts the front end of the locking rod 16. The elastic force of the spring 17 pushes the locking rod 16, so that the locking rod 16 squeezes the positioning protrusion 801 and locks the self-locking strip 8.

[0022] In this embodiment, a pressure block 14 is fixed in the middle of the fixing band 2, and a limiting protrusion 15 is fixed at both ends of the fixing band 2. The limiting protrusion 15 has the same T-shaped structure as the limiting T-groove 401, which facilitates insertion into the limiting T-groove 401.

[0023] In this embodiment, the fixing strap 2 is a transparent soft plastic sheet or soft plastic film, and the thickness of the fixing strap 2 is between 0.01mm and 1mm.

[0024] In this embodiment, two limiting T-shaped grooves 401 are symmetrically arranged on the adjusting shaft 4.

[0025] In this embodiment, the gasket 13 is made of a flexible material such as rubber or silicone.

[0026] In this embodiment, when using this device for compression hemostasis, a disposable protective sticker is attached to the pad 13 to prevent the reusable pad 13 from directly contacting the patient and causing infection. Then, the two ends of the fixing strap 2 are passed through the two limiting rotating shafts 11 on both sides, and the limiting protrusions 15 at both ends of the fixing strap 2 are inserted into the limiting T-grooves 401 of the adjusting rotating shaft 4. At the same time, the push-pull button 9 is pulled upward so that the squeezing force between the positioning protrusion 801 and the locking rod 16 overcomes the elastic force of the spring 17, and the self-locking strip 8 slides upward until the positioning protrusion 801 slides to the upper side of the locking rod 16, and at the same time the self-locking strip 8 separates from the self-locking rotating plate 6.

[0027] Place the area requiring pressure hemostasis between the pad 13 and the pressure block 14. Rotate the knob 7 to drive the rotating shaft 5, which in turn rotates the adjusting shaft 4 to retract the fixing strap 2 until the pressure block 14 presses against the patient, completing pressure hemostasis. Then, press down on the push-pull button 9 to overcome the spring force of the spring 17 between the positioning protrusion 801 and the locking rod 16. The self-locking strip 8 slides downward, and the positioning protrusion 801 slides to the underside of the locking rod 16. At the same time, the self-locking strip 8 contacts the self-locking turntable 6. 8 contacts the serrated part on the side of the self-locking turntable 6, locking the adjusting shaft 4. The spring force of the spring 17 is used to press the positioning protrusion 801, locking the self-locking clip 801 to prevent loosening and ensuring the self-locking clip 8 firmly locks the adjusting shaft 4. The adjusting shaft 4 is used to wind up the fixing strap 2, adjusting its tightness and thus the pressure for hemostasis. The locking rod 16 is used to lock the self-locking clip 8, preventing the fixing strap 2 from loosening during hemostasis and affecting its effectiveness.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
