When the size of the patient's body type does not match the size of the normal use, the position of the paste can be adjusted. However, the device does not have a height adjustment structure, and when performing hemostasis on the femoral artery of the patient, the patient often needs to lift the limb part. Long-term lifting is easy to cause pain in the limb part of the patient, causing discomfort of the patient.

[0007] Therefore, we propose a femoral artery puncture post-hemostasis compressor to solve the above problems. SUMMARY

[0009] To achieve the above purpose, the present application provides the following technical scheme: a femoral artery puncture post-hemostasis compressor, comprising a support base installed on the upper end of a guide wheel, and the guide wheel is used to provide power for the movement of the support base; further comprising a support frame installed on the upper end of the support base, and the support frame is in inverted "L" shape structure in side view, a threaded rod is rotatably connected to the inner side of the support frame, and an adjusting assembly is connected to the outer side of the threaded rod, the height of the compressor body is adjusted by the adjusting assembly, so that it is moved to the appropriate height for the patient to use; a connecting assembly is installed on the outer side of the compressor body, so that the two ends of the compressor body are fixed together by the connecting assembly, the femoral artery puncture site is compressed, and the hemostasis effect is achieved; flexible air pipes are installed equidistantly on the inner side of the compressor body, and inflation assemblies are fixedly connected to the outer side of the flexible air pipes, air is supplied to the inner side of the flexible air pipes by the inflation assemblies, so as to improve the compression effect of the compressor body.

[0010] Preferably, the adjusting assembly comprises a threaded connector and a fixing frame, the threaded connector is threadedly connected to the outer side of the threaded rod, and the fixing frame is fixedly installed on the outer side of the threaded connector; this structure is threadedly connected by the threaded hole formed on the inner side of the threaded connector and the threaded rod, and the threaded connector can be moved up and down by the rotation of the threaded rod.

[0011] Preferably, the upper end of the support base is provided with a compressor body, and a first concentric shaft is fixedly installed on the outside of the compressor body, and a fixing frame is nested on the outside of the first concentric shaft; this structure allows the compressor body to be angled at the lower end of the fixing frame through the first concentric shaft, thereby better fixing the patient's limb.

[0012] Preferably, a rotating disk is fixedly installed on the outer side of the threaded rod, and limit holes are opened at equal angles on the inner side of the rotating disk, and a handle is fixedly installed on the outer side of the rotating disk; this structure allows the tail end of the limit rod to engage with the corresponding limit hole by opening limit holes at equal angles on the inner side of the rotating disk, thereby fixing the rotating disk.

[0013] Preferably, a fixed rod is fixedly installed on the upper end of the support frame, and a telescopic spring is fixedly installed on the outside of the fixed rod. A limit rod is fixedly connected to the tail end of the telescopic spring, and the limit rod passes through the inside of the fixed rod, with the tail end of the limit rod connected to the inside of the limit hole. This structure can use the elastic force of the telescopic spring to make the limit rod reset itself and engage with the corresponding limit hole.

[0014] Preferably, a sliding rail is fixedly installed on the inner side of the support frame, and two sets of sliding rails are arranged symmetrically about the midpoint of the support frame. A sliding rod is nested inside the sliding rail, and the tail end of the sliding rod is fixedly installed on the outer side of the fixed frame. This structure can limit the angle of the fixed frame by sliding the sliding rod inside the sliding rail.

[0015] Preferably, the connecting assembly includes a second concentric shaft and a buckle. The second concentric shaft is fixedly installed on the outer side of the upper end of the compressor body, and the buckle is rotatably connected to the outer side of the second concentric shaft. This structure allows the buckle to be adjusted in angle via the second concentric shaft.

[0016] Preferably, a connecting strap is fixedly connected to the lower outer side of the compressor body, and the connecting strap is wrapped around the outside of the buckle. The first end of the connecting strap is fixedly connected to a first Velcro, and the tail end of the connecting strap is fixedly connected to a second Velcro, and the first Velcro and the second Velcro are adhesively connected. This structure can fix the connecting strap by the adhesion of the first Velcro and the second Velcro, preventing the sides of the compressor body from loosening.

[0017] Preferably, the inflation assembly includes an air inlet pipe and an air delivery device. The air inlet pipe is fixedly connected to the outside of the flexible air tube and penetrates the inside of the compressor body. The air delivery device is fixedly connected to the tail end of the air inlet pipe, and a valve is fixedly installed on the outside of the air inlet pipe. This structure can use the air delivery device to inject gas into the flexible air tube to push open the compressor body on the outside.

[0018] Preferably, a heat-insulating pad is fixedly installed on the inner side of the compressor body, and two sets of heat-insulating pads are arranged symmetrically about the midpoint of the flexible trachea; this structure can prevent heat loss from the outer side of the limb through the setting of the heat-insulating pad.

[0019] Compared with the prior art, the beneficial effect of the present invention is that the hemostatic compressor for femoral artery puncture is provided with:

[0020] (1) The height adjustment structure, through the rotation of the threaded rod, drives the threaded connector of the outer threaded connection to move the fixed frame up and down. As the fixed frame moves up and down, the compression body connected at the lower end will also move up and down, so that the compression body moves to a state that is level with the limb, and supports the patient's limbs to avoid the patient from raising the limbs for a long time and causing limb soreness.

[0021] (2) Hemostasis and compression structure: Place the patient's limb inside the body of the compression device, then roll up the body of the compression device to fit the patient's skin surface, then wrap the connecting strap around the inside of the buckle and tighten it, so that the connecting strap drives the compression device body on both sides of the limb to tighten, compress the femoral artery on the inside of the limb, and prevent continuous bleeding at the femoral artery puncture site.

[0022] (3) Secondary hemostasis compression component: gas is delivered to the air inlet tube through the gas delivery device. The delivered gas enters the inner side of the flexible trachea, thereby causing the flexible trachea to expand after being inflated, which opens the body of the compressor and makes the inner side of the compressor body fit more tightly against the patient's skin surface, so as to better compress the femoral artery and prevent incomplete hemostasis caused by insufficient compression.

[0023] Furthermore, after the height of the adjustment component is adjusted, the tension of the telescopic spring causes the limit rod to reset itself and engage with the corresponding limit hole on the inner side of the rotating disk. The engagement of the tail end of the limit rod with the limit hole fixes the rotating disk, thereby preventing the threaded rod from rotating and causing the presser body to move up and down.

[0024] Furthermore, by sliding the sliding rod inside the sliding track, the sliding rod limits the angle of the fixed frame, preventing the fixed frame from rotating when moving up and down. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides a technical solution:

[0036] Example 1: As Figures 1-4The technical solution shown is a compression device for hemostasis after femoral artery puncture, which discloses: a support base 1, which is mounted on the upper end of a guide wheel 2, and the guide wheel 2 is used to provide the power for the movement of the support base 1; it also includes a support frame 3, which is mounted on the upper end of the support base 1, and the support frame 3 has an inverted "L" shape structure in side view. A threaded rod 4 is rotatably connected to the inner side of the support frame 3, and an adjustment component is connected to the outer side of the threaded rod 4. The height of the compression device body 9 is adjusted by the adjustment component to move it to a suitable height for convenient use by the patient; a connecting component is installed on the outer side of the compression device body 9, which fixes the two ends of the compression device body 9 together to compress the femoral artery puncture site and achieve the hemostasis effect; flexible air tubes 23 are equidistantly installed on the inner side of the compression device body 9, and an inflation component is fixedly connected to the outer side of the flexible air tubes 23. The inflation component delivers air to the inner side of the flexible air tubes 23, thereby improving the compression effect of the compression device body 9;

[0037] The adjustment assembly includes a threaded connector 6 and a fixing bracket 7. The threaded connector 6 is threaded onto the outside of the threaded rod 4, and the fixing bracket 7 is fixedly installed on the outside of the threaded connector 6. A compressor body 9 is provided at the upper end of the support base 1, and a first concentric shaft 8 is fixedly installed on the outside of the compressor body 9, with the fixing bracket 7 nested on the outside of the first concentric shaft 8. A rotating disk 10 is fixedly installed on the outside of the threaded rod 4, and limit holes 11 are formed at equal angles on the inner side of the rotating disk 10. A handle 12 is fixedly installed on the outside of the rotating disk 10. A fixed rod 13 is fixedly installed at the upper end of the support frame 3, and a telescopic spring 14 is fixedly installed on the outside of the fixed rod 13. A limit rod 15 is fixedly connected to the tail end of the telescopic spring 14, and the limit rod 15 passes through the inside of the fixed rod 13. The tail end of the limit rod 15 is connected to the inside of the limit hole 11. A sliding rail 17 is fixedly installed on the inside of the support frame 3, and two sets of sliding rails 17 are symmetrically arranged about the midpoint of the support frame 3. A sliding rod 16 is nested inside the sliding rail 17, and the tail end of the sliding rod 16 is fixedly installed on the outside of the fixed frame 7.

[0038] When this structure is needed to stop bleeding in the femoral artery, the patient's limb is first placed inside the compressor body 9 for fixation. Then, the limiting rod 15 is pulled to separate the tail end of the limiting rod 15 from the inside of the limiting hole 11. After separation, the rotating disk 10 is in an active state. The rotating disk 10 is manually rotated by the handle 12. The rotation of the rotating disk 10 will drive the inner threaded rod 4 to rotate, thereby causing the threaded connector 6 connected to the outer threaded rod 4 to move up and down. The up and down movement of the threaded connector 6 will drive the fixing frame 7 to move up and down as well (the sliding rod 16 slides inside the sliding track 17, thereby fixing the fixing frame). 7. Angle limit): When the fixing frame 7 moves upward, it will drive the lower end of the compressor body 9 to move upward as well, thereby lifting the patient's limbs upward to avoid contact with the ground or table and getting cold. At the same time, lifting the patient's limbs can prevent blood from flowing to the lower limbs and play a certain role in hemostasis. When the compressor body 9 rises to a certain height, the limit rod 15 is released. The limit rod 15 is reset by the elastic force of the telescopic spring 14, thereby engaging with the corresponding limit hole 11, fixing the rotating disk 10 and preventing the threaded rod 4 on the inner side of the rotating disk 10 from rotating and causing the compressor body 9 to move up and down.

[0039] Example 2: Unlike Example 1, in addition to adjusting the height, a structure for compressing the femoral artery is added, such as... Figure 1 , Figures 5-7 The present invention provides a technical solution for hemostasis after femoral artery puncture, which discloses that: the connecting component includes a second concentric shaft 18 and a buckle 19, the second concentric shaft 18 is fixedly installed on the outer side of the upper end of the compressor body 9, and the buckle 19 is rotatably connected to the outer side of the second concentric shaft 18; a connecting strap 20 is fixedly connected to the outer side of the lower end of the compressor body 9, and the connecting strap 20 is wrapped around the outer side of the buckle 19, the first end of the connecting strap 20 is fixedly connected to a first Velcro 21, and the tail end of the connecting strap 20 is fixedly connected to a second Velcro 22, and the first Velcro 21 and the second Velcro 22 are adhesively connected;

[0040] When this structure is used to stop bleeding at the femoral artery puncture site, the compressor body 9 is first placed on the corresponding part of the limb. Then, the two sides of the compressor body 9 are pulled and rolled up so that both ends fit against the outside of the limb. After fitting, the connecting strap 20 is wrapped around the outside of the buckle 19 and tightened, so that the two sides of the compressor body 9 fit tightly against the outside of the limb, compressing the femoral artery at the limb site and preventing blood from flowing to the femoral artery puncture site. After tightening, the second Velcro 22 at the end of the connecting strap 20 is glued to the outside of the first Velcro 21, thereby fixing the connecting strap 20.

[0041] Example 3: Unlike Example 1, secondary compression is applied simultaneously with compression of the femoral artery, such as... Figure 1 ,Figure 8 The present invention provides a technical solution for hemostasis after femoral artery puncture, which discloses that: the inflation assembly includes an air inlet pipe 24 and an air delivery device 25. The air inlet pipe 24 is fixedly connected to the outside of the flexible air tube 23 and penetrates the inside of the compressor body 9. The tail end of the air inlet pipe 24 is fixedly connected to the air delivery device 25, and a valve 26 is fixedly installed on the outside of the air inlet pipe 24. A heat insulation pad 5 is fixedly installed on the inside of the compressor body 9, and two sets of heat insulation pads 5 are symmetrically arranged about the midpoint of the flexible air tube 23.

[0042] When the compressor body 9 applies pressure to the femoral artery, valve 26 is opened, and gas is injected into the inside of the air inlet tube 24 through the gas delivery device 25. The injected gas is diverted to the inside of multiple sets of flexible air tubes 23, causing the flexible air tubes 23 to inflate and collide, pushing up the outer compressor body 9. As the compressor body 9 near the inside of the limb continues to bulge, it will apply secondary pressure to the femoral artery on the inside of the limb, thereby preventing insufficient compression of the femoral artery and blood leakage from the femoral artery puncture site. After the secondary compression is completed, valve 26 is closed, thereby preventing gas from escaping from the inside of the flexible air tubes 23. In addition, a heat-insulating pad 5 is installed on the inside of the compressor body 9, which can prevent heat loss from the outside of the limb skin.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
