Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a compressor suitable for arterial hemostasis of infants. Background Art

[0002] A radial artery compressor is a device used to compress the radial artery. It is usually used to stop bleeding in emergency situations or when measuring blood pressure. It is usually a belt or bandage made of elastic material. It can be fixed on the wrist to apply moderate pressure, thereby temporarily stopping the blood flow in the radial artery. When using a radial artery compressor, it is necessary to ensure the correct position, usually on the inside or outside of the wrist, close to the radial artery. Correct compression can be achieved by stopping blood flow through the artery, but at the same time, it is necessary to ensure that there will be no long-term adverse effects on blood circulation.

[0003] The existing radial artery compressor is fixed on the patient's wrist by a strap or bandage made of elastic material. If it is tied too tightly, it will affect venous return, while if it is tied too loosely, it will affect the compression and hemostasis effect. At the same time, the fixing method is relatively complicated and is not suitable for use by infants and young children. At the same time, when the radial artery to be compressed is on the outside of the wrist, the compression plate on the compressor cannot fit with the outside of the wrist during the compression process. Therefore, the present application provides a compressor suitable for arterial hemostasis of infants and young children to meet the needs. Utility Model Content

[0032] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a compression device suitable for arterial hemostasis of infants and young children, including an elastic support plate 1, which is integrally formed. The elastic support plate 1 is integrally formed by injection molding, and has high production efficiency, can achieve large-scale production, does not require additional subsequent processing, and reduces processing procedures and labor costs. Both ends of the elastic support plate 1 are provided with connecting belt connecting grooves 11, and the two side surfaces of the connecting belt 5 are fixedly connected with a plurality of mutually corresponding limiting convex strips 51. One connecting belt connecting groove 11 is used to fix the connecting belt 5, and the other connecting belt connecting groove 11 is sleeved with the connecting belt 5 and is used to engage with the limiting convex strip 51 of the connecting belt 5 for limiting, so that the distance between the two ends of the elastic support plate 1 can be adjusted by the connecting belt 5, so as to further fix the elastic support plate 1 on the patient's wrist, so as to avoid the elastic support plate 1 from being offset due to the movement of the patient, and the compression is not in place.

[0033] like Figure 3 and Figure 4 As shown, an auxiliary support plate 2 is installed on the inner surface of the bottom end of the elastic support plate 1, and the auxiliary support plate 2 is detachable. When the patient's palm is thin and the clamping force of the elastic support plate 1 itself is insufficient, the auxiliary support plate 2 can be installed to lift and limit the inner side of the patient's wrist, so that the elastic support plate 1 has a better clamping force. A compression structure 4 is fixedly connected to the outer edge of one end of the elastic support plate 1 away from the auxiliary support plate 2. The compression structure 4 is used to compress and stop bleeding on the wound after distal radial artery puncture intervention surgery. A pressurizing structure 3 is fixedly connected to the outer surface of the elastic support plate 1 close to the compression structure 4. The pressurizing structure 3 and the compression structure 4 are connected through an inflation tube 32. The pressurizing structure 3 pressurizes the inflatable airbag 42 inside the compression structure 4 through the inflation tube 32, and then the inflatable airbag 42 expands after pressurization, and the inflated inflatable airbag 42 squeezes the compression plate 43, and the postoperative wound is compressed and stopped by the compression plate 43.

[0034] like Figure 2 and Figure 3As shown, the elastic support plate 1 is connected by a first adapting section 15, a first deforming section 16 and a second adapting section 17. The shape of the first adapting section 15 is adapted to the shape of the inner side of the patient's wrist. The first deforming section 16 is used to engage and limit with the side of the patient's wrist. The shape of the second adapting section 17 is adapted to the shape of the outer side of the patient's wrist. The elastic support plate 1 with a clamp-like structure is used to be clamped at the patient's wrist, so that the compression structure 4 on the second adapting section 17 corresponds to the position of the radial artery to be compressed on the outer side of the patient's wrist. The elastic support plate 1 is provided with a penetrating inflation cylinder mounting groove 12 and a compression mounting groove 18 at the corresponding positions of the pressurizing structure 3 and the compression structure 4, respectively. The inflation cylinder mounting groove 12 is used to provide an installation position for the pressurizing structure 3, and the compression mounting groove 18 is used to provide an installation position for the compression structure 4.

[0035] like Figure 2 As shown, the inner surface of the first adapting section 15 is provided with two support plate mounting grooves 14, and the auxiliary support plate 2 is mainly composed of a limiting section 21, an extrusion section 22 and a second deformation section 23. The two ends of the extrusion section 22 are respectively connected to the limiting section 21 and the second deformation section 23. The extrusion section 22 is a raised arc plate structure, the limiting section 21 is an arc plate structure and its curvature is opposite to that of the extrusion section 22. The thickness of the second deformation section 23 gradually changes from thin to thick from the middle to both sides. Therefore, when the inner side of the patient's wrist presses the extrusion section 22, the extrusion section 22 can change the protrusion height under the deformation of the second deformation section 23, so as to adapt to patients with various wrist thicknesses. Specifically, a snap-fit ​​portion 24 is provided at the end of the second deformation section 23. After the snap-fit ​​portion 24 of the second deformation section 23 is inserted into the support plate mounting groove 14, it is snap-fitted and positioned with the support plate mounting groove 14. After the end of the limiting section 21 is inserted into the support plate mounting groove 14, it is limited by its own curvature and the thickness of the extrusion section 22 with the support plate mounting groove 14. When the auxiliary support plate 2 needs to be disassembled, the extrusion section 22 is pressed in the direction of the second deformation section 23, so that the limiting section 21 and the extrusion section 22 move toward the second deformation section 23 until one end of the limiting section 21 is pulled out from the support plate mounting groove 14. When the limiting section 21 is pulled out, the extrusion section 22 is pulled in the opposite direction, so that the snap-fit ​​portion 24 of the second deformation section 23 can be pulled out from the other support plate mounting groove 14, and the entire auxiliary support plate 2 can be disassembled.

[0036] like Figures 1 to 4As shown, the compression structure 4 includes a connecting shell 41 fixedly connected to the inner surface of the compression mounting groove 18, the connecting shell 41 is used to install the inflatable airbag 42 and the compression plate 43, the inner top end of the connecting shell 41 is fixedly connected to the inflatable airbag 42, and one side surface of the inflatable airbag 42 is fixedly connected to two airbag interfaces 421 connected to the inside of the inflatable airbag 42, and the inside of the airbag interface 421 is nested with a one-way valve, which is the prior art. One airbag interface 421 penetrates the connecting shell 41 and extends to the outside of the connecting shell 41, and is used to connect with the inflation tube 32, and the other airbag interface 421 penetrates the connecting shell 41 and extends to the surface of the connecting shell 41, and is used to deflate the inflatable airbag 42 after hemostasis, and the gas inside the inflatable airbag 42 can be discharged through the thin tube by inserting the external thin tube into the airbag interface 421, and the airbag interface 421 is fixedly connected to one end of the inflation tube 32.

[0037] like Figure 3 and Figure 4 As shown, the outer wall of the inflatable airbag 42 has an annular corrugated structure. The inflatable airbag 42 with an annular corrugated structure expands under the pressure of the pressurizing structure 3. Since one end of the inflatable airbag 42 is fixed to the inner top of the connecting shell 41, the inflated inflatable airbag 42 will extend along the inside of the connecting shell 41. The extended inflatable airbag 42 will drive the compression plate 43 connected thereto to compress the position of the patient's radial artery to be compressed, thereby performing compression and hemostasis of the wound after distal radial artery puncture interventional surgery.

[0038] like Figure 3 and Figure 4 As shown, a compression plate 43 is fixedly connected to the bottom end of the inflatable airbag 42, and sliding columns 431 are fixedly connected to both ends of one side surface of the compression plate 43. The sliding column 431 is slidably connected to the connecting shell 41. The compression plate 43 is an arc-shaped structure, and the compression plate 43 is a rubber arc-shaped structure. Under the squeezing of the inflatable airbag 42, the compression plate 43 made of rubber will fit more closely to the position of the radial artery to be compressed of the patient, and the squeezing force on the position of the radial artery to be compressed will be more uniform. At the same time, the arc-shaped structure is adapted to the position of the radial artery to be compressed on the outside of the patient's wrist, and the compression fit is tighter.

[0039] like Figure 4 As shown, a limited sliding groove is provided at the bottom end of the connecting shell 41 at a position corresponding to the sliding column 431, and the compression plate 43 and the connecting shell 41 are slidably connected through the sliding column 431 and the limited sliding groove. The sliding connection between the compression plate 43 and the connecting shell 41 is realized by the sliding column 431, and the movement trajectory of the compression plate 43 can be limited so that it can only move along the direction of the limited sliding groove, thereby avoiding the displacement of the moving position due to the expansion of the inflatable airbag 42.

[0040] like Figure 1 and Figure 3 As shown, the pressurizing structure 3 includes a push-type inflator 34 fixedly connected to the inner surface wall of the inflator mounting groove 12. The push-type inflator 34 is a prior art. By pressing the push-type inflator 34, the inflatable airbag 42 can be inflated through the inflatable tube 32 connected thereto. The top of the push-type inflator 34 is fixedly connected with a pressing plate 31. The surface of the pressing plate 31 is adapted to the surface shape of the user's thumb. The surface of the pressing plate 31 adapted to the surface shape of the user's thumb can be pressed and inflated by the user, and the finger pressing part is more comfortable. The elastic support plate 1 is provided with a trachea groove 13 on the outer surface wall near the push-type inflator 34. The bottom outer surface wall of the push-type inflator 34 is fixedly connected with a connected inflator interface 33. The position of the inflator interface 33 is in the trachea groove 13, and the inflator interface 33 is fixedly connected to one end of the inflator tube 32.

[0041] The working principle of the utility model is as follows: when it is necessary to compress and stop bleeding on the wound after the patient's distal radial artery puncture interventional surgery, the elastic support plate 1 is opened and inserted into the patient's wrist, so that the compression structure 4 is aligned with the patient's position to be compressed and stopped bleeding, and then the connecting belt 5 is inserted into the connecting belt connecting groove 11, and the limiting convex strips 51 on the connecting belt 5 are mutually engaged to limit the position, so that the distance between the two ends of the elastic support plate 1 can be adjusted by the connecting belt 5, so as to further fix the elastic support plate 1 on the patient's wrist, and then the medical staff presses the push-type inflator The air cylinder 34 can inflate the inflatable airbag 42 through the inflation tube 32 connected to it. The inflatable airbag 42 with an annular corrugated structure expands under the pressure of the pressurized structure 3. Since one end of the inflatable airbag 42 is fixed to the inner top of the connecting shell 41, the inflated inflatable airbag 42 will extend along the inside of the connecting shell 41. The extended inflatable airbag 42 will drive the compression plate 43 connected to it to compress the position of the patient's radial artery to be compressed, thereby compressing the wound and stopping bleeding after distal radial artery puncture interventional surgery.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the preferred embodiment of the present invention, and the present invention can be fully understood by those skilled in the art without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
