Description
Technical Field
The utility model belongs to the technical field of radial artery intervention treatment and specifically relates to a radial artery compression tourniquet with pulse detection function is related to.
Background
Interventional radiology has a wide development space in its application field, and is known as medicine of twenty-first century. Interventional therapy has been widely used in clinical disease treatment with its advantages of minimal invasion, efficacy, low risk, etc. The blood vessel puncture interventional technique is one of the main techniques of interventional therapy, and simultaneously, the radial artery has the advantages of large inner diameter, difficult damage of blood circulation, easy mastering of the technique, capability of being placed into a large sheath tube according to the requirement and the like, so the radial artery puncture is a frequently selected puncture part in the blood vessel interventional technique.
With the progress of science and technology and the requirement of patients on minimally invasive operation, more and more patients adopt interventional operation for treating heart system diseases through radial artery and femoral artery access in recent years; however, the interventional treatment of arterial puncture is not completely non-invasive, and due to puncture in the operation and the insertion of the sheath, a wound still remains at the puncture part, and although the wound is small and does not need to be sutured, the hemostasis and the dressing still need to be performed by adopting a compression method after the puncture due to the large blood flow volume, the fast flow rate and the like of the artery.
The existing radial artery compression tourniquet is an arc-shaped pressing plate with an arm fixing strap, a pressing block is arranged on the inner side surface of the arc-shaped pressing plate, and a lead screw adjusting device is arranged on the outer side surface of the arc-shaped pressing plate; when the device is used, the pressing block is aligned to a puncture point and fixed on an arm through the fixed adhesive tape, and then the screw rod adjusting device is adjusted to enable the pressing block to tightly press the puncture point for 3-4 hours; in actual operation, the pressing force is difficult to grasp and is operated by a nurse according to experience, so that whether the pressing force blocks a blood vessel cannot be accurately judged, once the blood vessel is blocked for a long time, blood stasis or blood stasis green can be generated around the pressed part, discomfort and secondary injury are brought to a patient, and unconsciousness, necrosis and the like of an arm behind a puncture point can be caused in severe cases.
Disclosure of Invention
The utility model aims to provide a radial artery compression tourniquet with pulse detects function.
In order to achieve the above purpose, the utility model can adopt the following technical proposal:
the radial artery compression tourniquet comprises an arc-shaped pressing plate with an arm fixing band, wherein a flexible pressing block is arranged on the lower surface of the arc-shaped pressing plate, a lead screw adjusting device is arranged on the upper surface of the arc-shaped pressing plate, and a lead screw adjusting rod of the lead screw adjusting device vertically extends downwards to extend through the arc-shaped pressing plate to be fixedly connected with the flexible pressing block; the flexible pressing block is of a hollow rectangular structure, a hemostatic dressing layer is coated on the bottom surface of the flexible pressing block, a water injection pipe communicated with a hollow inner cavity of the flexible pressing block is hermetically arranged on the side wall of the flexible pressing block, and a sealing end cover is buckled at the outer end of the water injection pipe; a pressure type pulse detection sensor is hermetically arranged in the inner cavity of the flexible pressing block, and a pressure sensing film of the pressure type pulse detection sensor is attached to the bottom surface of the flexible pressing block; the pressure type pulse detection sensor is characterized in that a display screen is arranged on the arc-shaped pressing plate, a signal input end of the display screen is electrically connected with a signal output end of the pressure type pulse detection sensor, and a signal output end of the pressure sensing film is electrically connected with a signal input end of the pressure type pulse detection sensor.
The sealing end cover is fixedly connected to the outer wall of the water injection pipe through a flexible connecting arm.
The utility model has the advantages of simple structure and simple operation. When the radial artery is subjected to compression hemostasis, whether pulse exists at the puncture position is detected, if pulse does not exist, the flexible pressing block is pressed too tightly, blood flow is blocked, and at the moment, the pressure of the flexible pressing block can be adjusted by a patient or medical personnel through a lead screw adjusting device, so that discomfort and secondary damage to the patient are avoided, and long-time compression and nerve damage are prevented; the hemostatic dressing layer can accelerate the healing speed of the wound and reduce the possibility of scabbing of the contact surface of the puncture point, and in addition, cold water is injected into the inner cavity of the flexible pressing block through the water injection pipe, so that the blood coagulation of the puncture point can be accelerated, the compression time is reduced, and the incidence rate of radial artery occlusion and nerve injury is reduced.

FIG. 2 is an enlarged view of the compliant compact of FIG. 1.
Fig. 3 is an enlarged sectional view taken along line a-a in fig. 2.
Detailed Description
As shown in fig. 1-3, radial artery compression tourniquet, including arc clamp plate 2 that has arm fixed band 1, be provided with flexible briquetting 3 (flexible briquetting 3 can adopt silica gel to make) at arc clamp plate 2 lower surface, its upper surface is provided with lead screw adjusting device 4, lead screw adjusting device 4's lead screw adjusting rod 5 extends arc clamp plate 2 perpendicularly downwards through, its lower extreme links firmly with flexible briquetting 3 mutually, adjusts lead screw adjusting rod 5 and changes the pressure of 3 pairs of puncture points of flexible briquetting.
The flexible pressing block 3 is of a hollow rectangular structure, the bottom surface of the flexible pressing block 3 is coated with the hemostatic dressing layer 6, and the hemostatic dressing layer 6 can accelerate the healing speed of a wound and reduce the possibility of scabbing of a contact surface of a puncture point; a water injection pipe 7 communicated with a hollow inner cavity of the flexible pressing block 3 is hermetically arranged on the side wall of the flexible pressing block, a sealing end cover 8 is buckled at the outer end of the water injection pipe 7, a flexible connecting arm 12 is arranged on the sealing end cover 8 in order to avoid the loss of the sealing end cover 8, and the outer end of the flexible connecting arm 12 is fixedly connected to the outer wall of the water injection pipe 7; since the ice compress can help blood coagulation, cold water or ice water can be injected into the inner cavity of the flexible pressing block 3 through the water injection pipe 7, so that the blood coagulation at the puncture point is accelerated, and the compression time is shortened.
