Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an internal jugular vein compressor. Background Art

[0002] PICC catheter, also known as peripherally inserted central venous catheterization, uses a catheter to puncture the peripheral arm vein and allow the catheter to reach the large vein close to the heart. This not only avoids direct contact between chemotherapy drugs and arm veins, but also because the blood flow in large veins is extremely fast, it can quickly dilute chemotherapy drugs and prevent drugs from irritating blood vessels. Therefore, PICC catheters can effectively protect upper limb veins and reduce the incidence of phlebitis.

[0003] Since the ideal position of the PICC catheter tip is the area adjacent to the right atrium of the superior vena cava, in order to prevent the catheter from being mistakenly placed in the internal jugular vein during the catheterization operation, when the PICC catheter delivery length reaches 20 to 25 cm, medical staff usually instruct patients to tilt their heads toward the catheterization side and press their lower jaw against the acromion on the puncture side, thereby reducing the possibility of catheter malposition entering the internal jugular vein. However, for patients who have undergone tracheotomy, the presence of a tracheotomy tube in their neck limits neck movement, making it difficult to effectively turn their heads to compress the internal jugular vein, thereby increasing the risk of PICC catheter malposition. Summary of the invention

The card slot 302 is a semicircular slot body, and the overall profile of the lower clamping plate 201 is a "U"-shaped plastic plate. One end of the connecting plate 202 is fixedly connected to the outer wall of one end of the lower clamping plate 201. The connecting plate 202 is a rectangular plastic straight plate. From the side, the upper clamping plate 2, the connecting plate 202 and the lower clamping plate 201 form a "U" shape, which allows the upper clamping plate 2 and the lower clamping plate 201 of the U-shaped structure to be plugged into one end of the bed board of the operating bed 1, and the plastic plate with an upward curvature is One end of the inner splint 205 is fixedly connected to the top outer wall of the lower splint 201 and is distributed in a linear array. During use, the upper splint 2 is fixed with the help of the patient's own pressure, and the outer wall of one end of the inner splint 205 with an upward curvature on the top outer wall of the lower splint 201 will rest against the bottom outer wall of the bed board, thereby improving the stability and firmness of the upper splint 2 and the lower splint 201 after they are plugged in.

At the same time, it can also be adjusted according to the patient's neck size to adapt to different patients. At the same time, it can also adapt to the curvature of the patient's back neck and the size of the back of the head, thereby improving the patient's comfort when inserting the PICC catheter.

When the patient places the back of the neck on the top outer wall of the cervical vertebra support plate 203, the cervical vertebra support plate 203 will bend toward the direction of the lower splint 201 under the action of the patient's own gravity. At the same time, the two sides of the cervical vertebra support plate 203 with an arc will deform outward on both sides. Such a setting can adapt to different patients. The back of the head support plate 204 conforms to the back of the patient's neck contour and supports the back of the patient's neck, which is ergonomic and improves the patient's comfort. One end of the back of the head support plate 204 is fixedly connected to one end of the cervical vertebra support plate 203. The back of the head support plate 204 is a plastic semicircular arc plate with an open end, and a plurality of segmented grooves are provided on the top outer wall of the open end of the back of the head support plate 204.

[0048] The elastic plate 303 is slidably connected to the inner wall of the sliding groove 301 opened on the fixed block 3. The elastic plate 303 is composed of two "C"-shaped elastic plates, which are made of plastic. When the elastic plate 303 is subjected to force, it will deform along the direction of its bending, and the two ends of the elastic plate 303 are fixedly connected to the outer walls of both sides of the same support plate 406. The support plate 406 is a plastic straight plate. One end of the clamping column 304 is fixedly connected to the outer wall of one side of the support plate 406. The clamping column 304 is a plastic cuboid with an arc on one side. The curved outer wall on the side of the connecting column 304 is adapted to the profile of the first limit slot 302 mentioned above. One end of the C-shaped elastic plate 405 is fixedly connected to one end of the support plate 406. The C-shaped elastic plate 405 is a "C"-shaped plastic plate. When the C-shaped elastic plate 405 is subjected to force, it will deform along the direction of its bending. The other end of the U-shaped elastic plate 4 is fixedly connected to one end of the C-shaped elastic plate 405. The overall profile of the U-shaped elastic plate 4 is a "U"-shaped plastic plate. A plurality of second limit slots are symmetrically distributed in a linear array. On the outer walls at both ends of the U-shaped elastic plate 4, the overall outline of the second limit slot is triangular, and the bottom end of the first hollow cylinder 402 is fixedly connected to the outer wall of the middle top of the U-shaped elastic plate 4. The first hollow cylinder 402 is a hollow cylinder, and a threaded groove 407 is opened on its inner wall. The threaded cylinder 401 is screwed on the inner wall of the first hollow cylinder 402. The threaded cylinder 401 consists of a "convex" shaped protrusion, a cylinder with threads, and a cylinder with an anti-slip groove. It is made of plastic.

The bottom end of the second hollow cylinder 403 is fixedly connected to the outer wall of the middle part of the top end of the first elastic plate 404. The first elastic plate 404 is a plastic plate with an arc, and its two ends are respectively fixedly connected to the outer walls of the U-shaped elastic plate 4 near the two ends.

[0049] When the end of the threaded cylinder 401 away from the first elastic plate 404 is twisted counterclockwise, the threaded cylinder 401 will rotate on the inner wall of the first hollow cylinder 402 and move in the direction away from the first elastic plate 404. At this time, the second hollow cylinder 403 rotatably connected to one end of the threaded cylinder 401 will move in the same direction. The first elastic plate 404 will deform inwardly at both ends as the second hollow cylinder 403 moves. At this time, the U-shaped elastic plate 4 will also deform inwardly at both ends as the first elastic plate 404 deforms, which will drive the elastic plate 303 slidably connected to the inner wall of the sliding groove 301 to move in the direction of contraction. Under the limit of the inner wall of the sliding groove 301, the elastic plate 303 will move along the The U-shaped elastic plate 405 is deformed in the bending direction, and the clamping column 304 is clamped into the first limiting clamping groove 302 opened on the inner wall of the sliding groove 301 under the drive of the support plate 406. At this time, the support plate 406 cooperates with the elastic plate 303 to no longer move under the limitation of the sliding groove 301, but the two ends of the U-shaped elastic plate 4 still shrink inward. At this time, the C-shaped elastic plate 405 is stressed and deformed along the bending direction. With the above structural setting, the U-shaped elastic plate 4 can be adjusted to a suitable position by sliding the elastic plate 303 according to the length of the patient's neck. Then, the threaded cylinder 401 is twisted counterclockwise to make the clamping column 304 clamped into the first limiting clamping groove 302 opened on the inner wall of the sliding groove 301, thereby limiting the U-shaped elastic plate 4.

One end of the two second frames 901 is symmetrically fixedly connected to the two sides of the third frame 902. The third frame 902 is a curved plastic plate. One end of the two fourth frames 903 is symmetrically fixedly connected to the outer walls at both ends of the third frame 902. The fourth frame 903 is a "C"-shaped plastic plate. When the fourth frame 903 is subjected to force, it will deform along the direction of its bending. The other ends of the two fourth frames 903 are fixedly connected to the outer walls at both ends of the same fifth frame 904. The fifth frame 904 is a curved plastic plate. When the fifth frame 904 is subjected to force, it will deform along the direction of its bending.

[0054] When the rubber airbag 8 needs to be cleaned, it is only necessary to pull the rubber airbag 8 in the direction away from the airbag base 7. At this time, the second frame 901 will cause the part of the curved plastic plate on the second frame 901 close to the first frame 9 to tilt inward as the rubber airbag 8 is pulled. At this time, the first frame 9 is squeezed by the second frame 901 so that it deforms along its bending direction. At the same time, the curved "C"-shaped plastic plate part on the second frame 901 is close to one end of the first frame 9. Under the action of the inward tilt of the part of the curved plastic plate on the second frame 901 close to the first frame 9, it will deform in the tilted direction. At this time, the rubber airbag 8 can be pulled out from the clamping groove 702 of the airbag base 7.

[0055] When the cleaning is completed, you only need to align the rubber airbag 8 with the snap-in groove 702 and press the neck contact surface 801 of the rubber airbag 8 hard. As the rubber airbag 8 is pressed, the curved "C"-shaped plastic plate part on the second skeleton 901 will be subjected to the resistance pressure from the inner wall of the snap-in groove 702, causing it to deform along the direction of its bending until the outer wall of the curved "C"-shaped plastic plate part on the second skeleton 901 is pushed into the semicircular groove body with a curve symmetrically arranged in the middle of the inner walls on both sides of the inner wall of the snap-in groove 702. At this time, the installation is completed.

[0056] When it is necessary to compress the patient's neck vein, as the threaded cylinder 401 is turned counterclockwise, the U-shaped elastic plate 4 undergoes deformation with both ends shrinking inward, which will drive the airbag base 7 to move toward the patient's neck. At this time, the neck contact surface 801 of the fifth skeleton 904 that presses against the rubber airbag 8 presses against the patient's neck, which will cause the fifth skeleton 904 to be stressed and deform along the direction of its bending. During the deformation of the fifth skeleton 904, an extrusion force will be applied to the fourth skeleton 903, causing the fourth skeleton 903 to deform along the direction of its bending. The above structural setting can not only shape the rubber airbag 8, but also achieve quick installation and disassembly when the rubber airbag 8 needs to be cleaned. In addition, it can also adapt to the patient's neck size to meet the needs of different patients, thereby improving the practicality of the device.

[0057] The workflow of the technical solution provided by the present invention is as follows:

[0058] First, plug the upper splint 2 and the lower splint 201 of the U-shaped structure into one end of the bed board of the operating bed 1, let the patient lie on the operating bed 1, and the cervical vertebra support plate 203 and the back of the head support plate 204 on the device will respectively support the back of the patient's neck and the back of the head. The cervical vertebra support plate 203 will bend toward the direction of the lower splint 201 under the action of the patient's own gravity; at the same time, the two sides of the curved cervical vertebra support plate 203 will expand outward on both sides, which can adapt to the back of the neck contour of different patients, support the back of the patient's neck, and meet the needs of different patients. Ergonomically designed to improve the patient's comfort, one end of the back of the head support plate 204 is fixedly connected to one end of the cervical vertebra support plate 203. The back of the head support plate 204 is a plastic semicircular arc plate with an open end, and a plurality of segmented grooves are provided on the top outer wall of the open end of the back of the head support plate 204. When the patient places the back of his head on the top outer wall of the back of the head support plate 204, the end of the back of the head support plate 204 with the plurality of segmented grooves will expand outward, which can adapt to the back of the head sizes of different patients.

[0059] Then, slide the elastic plate 303 into the sliding groove 301 provided on the fixing block 3, slide the elastic plate 303 to a suitable position according to the neck length of the patient, and twist the end of the threaded cylinder 401 away from the first elastic plate 404 counterclockwise. The threaded cylinder 401 will rotate on the inner wall of the first hollow cylinder 402 and move in the direction away from the first elastic plate 404. At this time, the second hollow cylinder 403 connected to one end of the threaded cylinder 401 will be rotated and move in the same direction. The first elastic plate 404 will be deformed with both ends contracting inwardly as the second hollow cylinder 403 is displaced. At this time, the U-shaped elastic plate 4 will also follow The deformation of the first elastic plate 404 causes both ends to contract inwardly, which will drive the elastic plate 303 slidably connected to the inner wall of the sliding groove 301 to move in the contraction direction. Under the limitation of the inner wall of the sliding groove 301, the elastic plate 303 will deform along its bending direction, and the clamping column 304 will be clamped into the first limiting clamping groove 302 opened on the inner wall of the sliding groove 301 under the drive of the support plate 406. At this time, the support plate 406 cooperates with the elastic plate 303 to no longer move under the limitation of the sliding groove 301, but the two ends of the U-shaped elastic plate 4 still contract inwardly. At this time, the C-shaped elastic plate 405 is subjected to force and deforms along its bending direction.

[0060] With the above structural setting, the U-shaped elastic plate 4 can be adjusted to a suitable position by sliding the elastic plate 303 according to the length of the patient's neck, and then the clamping column 304 can be clamped into the first limiting clamping groove 302 opened on the inner wall of the sliding groove 301 by twisting the threaded cylinder 401 counterclockwise, so as to limit the U-shaped elastic plate 4. At the same time, the U-shaped elastic plate 4 undergoes inward contraction at both ends, which will drive the airbag base 7 to move toward the patient's neck. At this time, the neck contact surface 801 of the rubber airbag 8 of the fifth skeleton 904 is against the patient's neck, which will cause the fifth skeleton 904 to be stressed and deformed along its bending direction. During the deformation of the fifth skeleton 904, an extrusion force will be applied to the fourth skeleton 903, causing the fourth skeleton 903 to deform along its bending direction, so as to adapt to the neck sizes of different patients.

[0061] When it is necessary to clean the rubber airbag 8, it is only necessary to pull the rubber airbag 8 in the direction away from the airbag base 7. At this time, the second frame 901 will cause the part of the curved plastic plate on the second frame 901 close to the first frame 9 to tilt inward as the rubber airbag 8 is pulled. At this time, the first frame 9 is squeezed by the second frame 901 so that it deforms along the direction of its bending. At the same time, the curved "C"-shaped plastic plate part on the second frame 901 is close to one end of the first frame 9. Under the effect of the inward tilt of the part of the curved plastic plate on the second frame 901 close to the first frame 9, it will deform in the tilted direction. At this time, the rubber airbag 8 can be cleaned. The bag 8 is pulled out from the snap-in groove 702 of the airbag base 7. When the cleaning is completed, it is only necessary to align the rubber airbag 8 with the snap-in groove 702 and press the neck contact surface 801 of the rubber airbag 8 hard. As the rubber airbag 8 is pressed, the curved "C"-shaped plastic plate part on the second skeleton 901 will be subjected to the resistance pressure from the inner wall of the snap-in groove 702, causing it to deform along the direction of its bending until the outer wall of the curved "C"-shaped plastic plate part on the second skeleton 901 is pushed into the curved semicircular groove body symmetrically arranged in the middle of the inner walls on both sides of the inner wall of the snap-in groove 702. At this time, the installation is completed.
