Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, especially a jugular vein compressor. BACKGROUND

[0002] PICC catheter, that is, peripheral intravenous puncture central venous catheterization, is to puncture the peripheral arm vein with the help of a catheter, and the catheter reaches the large vein near the heart directly. In this way, the direct contact of the chemotherapy drugs with the arm vein is avoided, and the blood flow speed of the large vein is extremely fast, so that the chemotherapy drugs can be quickly diluted to prevent the drugs from causing irritation to the blood vessels. Therefore, the PICC catheter can effectively protect the upper limb vein and reduce the incidence of phlebitis.

[0003] Since the ideal position of the tip of the PICC catheter is the superior vena cava adjacent to the right atrium region, in the process of implementing the catheterization operation, in order to prevent the catheter from being mispositioned into the internal jugular vein, when the catheter length of the PICC catheter reaches 20 to 25 centimeters, the medical staff usually instruct the patient to turn his head to the catheterization side, and at the same time, the chin is tightly pressed against the shoulder peak of the puncture side, so as to reduce the possibility of the catheter being mispositioned into the internal jugular vein. However, for those patients who have undergone tracheostomy surgery, the tracheostomy cannula in the neck restricts the movement of the neck, making it difficult to effectively complete the action of turning the head to compress the internal jugular vein, thereby increasing the risk of mispositioning of the PICC catheter.

[0044] like Figures 1 to 13 As shown, an embodiment of this utility model provides an internal jugular vein compressor, including an upper splint 2 and a lower splint 201 installed on an operating table 1. Two fixing blocks 3 are symmetrically fixed to both sides of the outer wall of one end of the upper splint 2. A sliding groove 301 is provided on the top outer wall of the fixing block 3, and a plurality of first limiting slots 302 are provided on the inner wall of the sliding groove 301. A connecting plate 202 is fixedly connected to one end of the lower splint 201, and three inner splints 205 arranged linearly are fixedly connected to the lower splint 201. A compression component is used to compress the patient's jugular vein, and the compression component is connected to the fixing blocks 3 and the upper splint 2 respectively.

[0045] The upper clamping plate 2 is a plastic plate with an overall outline of "T". Two fixing blocks 3 are symmetrically fixed to the outer walls of one end of the upper clamping plate 2. The fixing blocks 3 are plastic cuboids. A sliding groove 301 is formed on the top outer wall of the fixing block 3. The sliding groove 301 has an overall outline of "convex" shape and extends through the other end of the fixing block 3. Several first limiting slots 302 are formed on the inner wall of the sliding groove 301 near the middle of the upper clamping plate 2, and are distributed in a linear array. The slot 302 is a semi-circular groove. The lower clamp 201 has an overall U-shaped plastic plate outline. One end of the connecting plate 202 is fixedly connected to the outer wall of one end of the lower clamp 201. The connecting plate 202 is a rectangular plastic straight plate. From the side, the outline formed by the cooperation between the upper clamp 2, the connecting plate 202, and the lower clamp 201 is a U-shape, allowing the U-shaped upper clamp 2 and lower clamp 201 to be inserted into one end of the operating table 1. The plastic plate has an upward curvature. One end of the inner clamp 205 is fixedly connected to the top outer wall of the lower clamp 201, and they are arranged in a linear array. During use, the upper clamp 2 is fixed by the patient's own pressure. The outer wall of one end of the inner clamp 205, which has an upward curvature on the top outer wall of the lower clamp 201, will abut against the bottom outer wall of the bed board, improving the stability and firmness of the upper clamp 2 and the lower clamp 201 after insertion. Secondly, this setting can also make the upper clamp 2 and the lower clamp 201 adaptable to operating beds 1 with different thicknesses, thereby improving the practicality of this device. The compression component provided in this application can compress the patient's jugular vein, so that the jugular vein near the superior vena cava is no longer prominent, avoiding the PICC catheter from entering the internal jugular vein by misplacement. At the same time, it can also be adjusted according to the size of the patient's neck to adapt to different patients. Meanwhile, it can also adapt to the curvature of the back of the patient's neck and the size of the back of the head, improving the patient's comfort when inserting the PICC catheter.

[0046] like Figures 1 to 13As shown, the compression assembly includes a cervical spine support plate 203 fixedly connected to the top outer wall of one end of the upper splint 2. A posterior head support plate 204 is fixedly connected to one end of the cervical spine support plate 203, and segmented grooves are formed on the outer wall of one end of the posterior head support plate 204. Specifically, one end of the cervical spine support plate 203 is fixedly connected to the top outer wall of one end of the upper splint 2. The cervical spine support plate 203 is a curved plastic plate that bends towards the top outer wall of the upper splint 2. Several segmented grooves are symmetrically formed on both sides of the top outer wall of the cervical spine support plate 203. When the patient places the back of their neck on the top outer wall of the cervical spine support plate 203, the cervical spine support plate 203 will bend towards the lower splint 201 under the influence of the patient's own weight. At the same time, the curved cervical spine support plate 203 will deform outwards on both sides. This design can adapt to different patients. The back of the neck is supported by the cervical spine support plate 203, which conforms to the ergonomic design and improves patient comfort. One end of the back of the head support plate 204 is fixedly connected to one end of the cervical spine support plate 203. The back of the head support plate 204 is an open plastic semi-circular arc plate with several segmented grooves on the top outer wall of the open end. When the patient places their back of the 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 several segmented grooves will expand outward. This design can adapt to the back of the head of different patients.

[0047] like Figures 1 to 13 As shown, the compression assembly includes an elastic plate 303 slidably connected to the inner wall of the sliding groove 301. Both ends of the elastic plate 303 are fixedly connected to the same support plate 406. A snap-fit ​​post 304 is fixedly connected to the outer wall of one end of the support plate 406. A C-shaped elastic plate 405 is fixedly connected to one end of the support plate 406. A U-shaped elastic plate 4 is fixedly connected to one end of the C-shaped elastic plate 405. Several second limiting slots are symmetrically opened on the outer walls of both ends of the U-shaped elastic plate 4. A first hollow cylinder 402 is fixedly connected to the outer wall of the top middle part of the U-shaped elastic plate 4. A threaded groove 407 is opened on the inner wall of the first hollow cylinder 402. A threaded cylinder 401 is screwed to the first hollow cylinder 402. A second hollow cylinder 403 is rotatably connected to one end of the threaded cylinder 401. A rotating groove 408 is opened on the inner wall of the second hollow cylinder 403. The first elastic plate 404 is fixedly connected to one end of the second hollow cylinder 403.

[0048] The elastic plate 303 is slidably connected to the inner wall of the sliding groove 301 formed in the fixed block 3. The elastic plate 303 consists of two parts of "C"-shaped elastic plates and is made of plastic. When the elastic plate 303 is stressed, it will deform along the direction of its bending. The two ends of the elastic plate 303 are fixedly connected to the outer walls on 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 on one side of the support plate 406. The clamping column 304 is a plastic cuboid with a radian on one side. The outer wall with a radian of the clamping column 304 is adapted to the contour of the first limiting card 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 stressed, 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 contour of the U-shaped elastic plate 4 is a "U"-shaped plastic plate. A number of second limiting card slots are symmetrically arranged in a linear array on the outer walls at both ends of the U-shaped elastic plate 4. The overall contour of the second limiting card slot is triangular. The bottom end of the first hollow cylinder 402 is fixedly connected to the outer wall at 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 formed in its inner wall. The threaded cylinder 401 is screwed into 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 anti-slip grooves, and is made of plastic. The second hollow cylinder 403 is rotatably connected to one end of the threaded cylinder 401. The second hollow cylinder 403 is a hollow plastic cylinder. A rotating groove 408 is formed in the inner wall of the second hollow cylinder 403. The cross-section of the overall contour of the rotating groove 408 is "convex"-shaped and is adapted to the contour of the "convex"-shaped protrusion on the threaded cylinder 401. The bottom end of the second hollow cylinder 403 is fixedly connected to the outer wall at the middle top of the first elastic plate 404. The first elastic plate 404 is a plastic plate with a radian, and its two ends are respectively fixedly connected to the outer walls of the U-shaped elastic plate 4 near both ends.

[0049] When the end of the threaded cylinder 401 away from the first elastic plate 404 is turned counterclockwise, the threaded cylinder 401 will rotate along the inner wall of the first hollow cylinder 402 and displace away from the first elastic plate 404. At this time, the second hollow cylinder 403, which is rotatably connected to one end of the threaded cylinder 401, will displace in the same direction. The first elastic plate 404 will deform inward at both ends as the second hollow cylinder 403 displaces. At this time, the U-shaped elastic plate 4 will also deform inward at both ends along the deformation of the first elastic plate 404. This will drive the elastic plate 303, which is slidably connected to the inner wall of the sliding groove 301, to displace in the direction of contraction. Under the limitation of the inner wall of the sliding groove 301, the elastic plate 303 will move along... The bending direction of the plate changes, and the locking post 304 will be locked into the first limiting slot 302 opened on the inner wall of the sliding groove 301 under the action of the support plate 406. At this time, the support plate 406, together with the elastic plate 303, will no longer move under the limitation of the sliding groove 301, but the two ends of the U-shaped elastic plate 4 will still contract inward. At this time, the C-shaped elastic plate 405 will be subjected to force and deform along its bending direction. With the above structural settings, 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, by turning the threaded cylinder 401 counterclockwise, the locking post 304 will be locked into the first limiting slot 302 opened on the inner wall of the sliding groove 301, thereby limiting the U-shaped elastic plate 4.

[0050] Sliding blocks 5 are symmetrically slidably connected to the outer walls of the U-shaped elastic plate 4 near both ends. A second elastic plate 501 is fixedly connected to one side of the outer wall of the sliding block 5. A third elastic plate 502 is fixedly connected to one end of the second elastic plate 501. A snap-fit ​​protrusion is provided at one end of the third elastic plate 502. A fourth elastic plate 6 is fixedly connected to one side of the sliding block 5. A fifth elastic plate 601 is fixedly connected to the top outer wall of one end of the fourth elastic plate 6. A mandibular support plate 603 is fixedly connected to one end of the fifth elastic plate 601. Segmented grooves are provided on both sides of the mandibular support plate 603.

[0051] Specifically, two sliding blocks 5 are symmetrically slidably connected to the outer walls of the U-shaped elastic plate 4 near both ends. Each sliding block 5 is a hollow cuboid with a rectangular groove on one side near the outer wall of the first elastic plate 404. One end of the second elastic plate 501 is fixedly connected to the outer wall of the sliding block 5 with the rectangular groove on one side. The second elastic plate 501 is a "C"-shaped plastic plate. The other end of the second elastic plate 501 is fixedly connected to the outer wall of the third elastic plate 502 on one side. The third elastic plate 502 is an "S"-shaped plastic plate with a snap-fit ​​protrusion at one end that matches the contour of the second limiting slot. When the third elastic plate 502 is subjected to force, it deforms along its bending direction, passes through the rectangular groove on the sliding block 5, and snaps into the second limiting slot. The fourth elastic plate 6 is fixedly connected to the outer wall of the other side of the sliding block 5. The fourth elastic plate 6 is an arc-shaped plastic plate. When the fourth elastic plate 6 is subjected to force, it will deform along its bending direction. A fifth elastic plate 601 is fixedly connected to the top outer wall of the end of the fourth elastic plate 6 away from the sliding block 5. The fifth elastic plate 601 is an arc-shaped "C" plastic plate. When the fifth elastic plate 601 is subjected to force, it will deform along its bending direction. One end of the fifth elastic plate 601 is fixedly connected to the bottom outer wall of the mandibular support plate 603. The mandibular support plate 603 is an arc-shaped "C" plastic plate, and segmented grooves are opened on both sides. The above structure can be adjusted according to the size of the patient's face shape and can also fit the contour of the patient's mandible, limiting the position of the patient's mandible to a certain extent, so as to avoid the patient subconsciously tilting their head when inserting the PICC catheter, causing the tracheostomy tube to rub against the inner wall of the trachea and causing discomfort to the patient.

[0052] like Figure 10 , Figure 12 and Figure 13 As shown, a sixth elastic plate 602 is fixedly connected to the top outer wall of one end of the fourth elastic plate 6. An airbag base 7 is fixedly connected to one end of the sixth elastic plate 602. A snap-fit ​​groove 702 is provided on the top outer wall of the airbag base 7. A rubber airbag 8 is fitted on the inner wall of the snap-fit ​​groove 702. A first frame 9 is fitted on the inner wall of the rubber airbag 8. A second frame 901 is symmetrically fixedly connected to both sides of the first frame 9. A third frame 902 is fixedly connected to one end of the second frame 901. A fourth frame 903 is symmetrically fixedly connected to the top outer walls of both ends of the third frame 902. The same fifth frame 904 is fixedly connected to one end of each of the two fourth frames 903.

[0053] Specifically, the sixth elastic plate 602 is fixedly connected to the top outer wall of the fourth elastic plate 6 located on the left side of the patient, near the upper splint 2. The sixth elastic plate 602 is a curved "C"-shaped plastic plate that deforms along its bending direction when subjected to force. The airbag base 7 is fixedly connected to one end of the sixth elastic plate 602. The airbag base 7 is a curved plastic cuboid, and a snap-fit ​​groove 702 is provided on the top outer wall of the airbag base 7. The snap-fit ​​groove 702 is a groove with an overall quadrilateral outline, and the inner walls on both sides... A semi-circular groove with an arc shape is symmetrically arranged in the middle. The rubber airbag 8 is fitted onto the inner wall of the snap-fit ​​groove 702. The rubber airbag 8 is made of rubber. Since the rubber airbag 8 is prior art, it will not be described in detail. The air inlet pipe 701 is fixedly connected to one side of the rubber airbag 8 and passes through a round hole on the outer wall of one end of the airbag base 7. The air inlet pipe 701 is a rubber pipe, and air can be delivered into the rubber airbag 8 through the air inlet pipe 701 by an air pump. The first frame 9 is fitted onto the inner wall of the rubber airbag 8. The first frame 9 has an arc shape. The first frame 9 consists of a C-shaped plastic plate, which deforms along its own bending direction when subjected to force. Two second frames 901 are symmetrically fixed to the outer walls on both sides of the first frame 9. Each second frame 901 consists of three parts: two curved plastic plates and one curved C-shaped plastic plate. When subjected to force, the curved C-shaped plastic plate part of the second frame 901 deforms along its bending direction. One end of each of the two second frames 901 is symmetrically fixed to both sides of the third frame 902, which is a curved plastic plate. One end of each of the two fourth frames 903 is symmetrically fixed to the outer walls at both ends of the third frame 902. Each fourth frame 903 is a C-shaped plastic plate, which deforms along its bending direction when subjected to force. The other ends of each of the two fourth frames 903 are fixedly fixed to the outer walls at both ends of the same fifth frame 904, which is a curved plastic plate, and deforms along its bending direction when subjected to force.

[0054] When it is necessary to clean the rubber airbag 8, simply pull the rubber airbag 8 away from the airbag base 7. At this time, the second frame 901 will pull the rubber airbag 8, causing the part of the second frame 901 near the first frame 9 to tilt inward. The first frame 9 will be subjected to the squeezing force from the second frame 901, causing it to deform along its bending direction. At the same time, the curved "C"-shaped plastic plate part of the second frame 901 near the end of the first frame 9 will deform in the tilting direction under the inward tilting action of the curved plastic plate part of the second frame 901. At this time, the rubber airbag 8 can be pulled out from the locking groove 702 of the airbag base 7.

[0055] After cleaning, simply align the rubber airbag 8 with the snap-fit ​​groove 702 and press firmly on the neck contact surface 801 of the rubber airbag 8. As the rubber airbag 8 is pressed, the curved "C"-shaped plastic plate on the second frame 901 will be subjected to the pressure from the inner wall of the snap-fit ​​groove 702, causing it to deform along its bending direction until the outer wall of the curved "C"-shaped plastic plate on the second frame 901 is pushed into the groove with a curved semi-circular shape symmetrically arranged in the middle of the two inner walls of the snap-fit ​​groove 702. At this point, the installation is complete.

[0056] When compression of the patient's jugular vein is required, as the threaded cylinder 401 is turned counterclockwise, the U-shaped elastic plate 4 deforms by contracting inward at both ends, causing the airbag base 7 to shift towards the patient's neck. At this time, the neck contact surface 801 of the fifth frame 904, which is pressed against the rubber airbag 8, presses against the patient's neck, causing the fifth frame 904 to be stressed and deform along its bending direction. During the deformation of the fifth frame 904, a compressive force is applied to the fourth frame 903, causing the fourth frame 903 to deform along its bending direction. The above structural design not only allows for shaping of the rubber airbag 8, but also enables quick installation and disassembly when the rubber airbag 8 needs to be cleaned. In addition, it can adapt to the patient's neck size, meet the needs of different patients, and improve the practicality of this device.

[0057] The workflow of the technical solution provided by this utility model is as follows:

[0058] First, the upper and lower U-shaped splints 2 and 201 are inserted into one end of the operating table 1. The patient lies on the operating table 1. The cervical spine support 203 and the posterior head support 204 of this device support the back of the patient's neck and the back of the head, respectively. The cervical spine support 203 bends towards the lower splint 201 under the patient's own weight. At the same time, the curved cervical spine support 203 deforms outward on both sides to adapt to the contours of different patients' necks, supporting the back of the neck. Ergonomically designed to improve patient comfort, the posterior head support plate 204 is fixedly connected to one end of the cervical spine support plate 203. The posterior head support plate 204 is an open-ended plastic semi-circular arc plate with several segmented grooves on the top outer wall of the open end. When the patient places their head on the top outer wall of the posterior head support plate 204, the end of the posterior head support plate 204 with several segmented grooves will expand outward to accommodate different patient head sizes.

[0059] Then, the elastic plate 303 is slid into the sliding groove 301 on the fixed block 3. The elastic plate 303 is slid to a suitable position according to the patient's neck length. The end of the threaded cylinder 401 away from the first elastic plate 404 is turned counterclockwise. The threaded cylinder 401 rotates along the inner wall of the first hollow cylinder 402, displacing away from the first elastic plate 404. At this time, the second hollow cylinder 403, which is rotated and connected to one end of the threaded cylinder 401, displaces in the same direction. The first elastic plate 404 deforms inward at both ends as the second hollow cylinder 403 displaces. The U-shaped elastic plate 4 also follows this deformation. The deformation of the first elastic plate 404 causes the two ends to contract inward, which will cause the elastic plate 303, which is slidably connected to the inner wall of the sliding groove 301, to move in the direction of contraction. Under the limitation of the inner wall of the sliding groove 301, the elastic plate 303 will deform along its bending direction. The locking post 304 will be locked into the first limiting slot 302 opened on the inner wall of the sliding groove 301 under the action of the support plate 406. At this time, the support plate 406 and the elastic plate 303 will no longer move under the limitation of the sliding groove 301, but the two ends of the U-shaped elastic plate 4 will still contract inward. At this time, the C-shaped elastic plate 405 will be subjected to force and deform along its bending direction.

[0060] The above structural design allows the sliding elastic plate 303 to adjust the U-shaped elastic plate 4 to a suitable position according to the length of the patient's neck. Then, by turning the threaded cylinder 401 counterclockwise, the locking post 304 is locked into the first limiting slot 302 opened on the inner wall of the sliding groove 301, thus limiting the U-shaped elastic plate 4. At the same time, the U-shaped elastic plate 4 deforms by contracting its two ends inward, which will cause the airbag base 7 to move towards the patient's neck. At this time, the neck contact surface 801 of the fifth frame 904 against the rubber airbag 8 is pressed against the patient's neck, which will cause the fifth frame 904 to be stressed and deform along its bending direction. During the deformation of the fifth frame 904, a compressive force will be applied to the fourth frame 903, causing the fourth frame 903 to deform along its bending direction, which can adapt to the neck size of different patients.

[0061] When cleaning the rubber airbag 8, simply pull the rubber airbag 8 away from the airbag base 7. The second frame 901 will then pull along with the rubber airbag 8, causing the curved plastic plate portion of the second frame 901 near the first frame 9 to tilt inwards. At this time, the first frame 9 is subjected to the compressive force from the second frame 901, causing it to deform along its bending direction. Simultaneously, the curved "C"-shaped plastic plate portion of the second frame 901 near the first frame 9 will deform in the tilting direction due to the inward tilting of the curved plastic plate portion of the second frame 901. This allows the rubber airbag to be cleaned. The airbag 8 is pulled out from the snap-fit ​​groove 702 of the airbag base 7. After cleaning, simply align the rubber airbag 8 with the snap-fit ​​groove 702 and press the neck contact surface 801 of the rubber airbag 8 firmly. As the rubber airbag 8 is pressed, the curved "C"-shaped plastic plate part on the second frame 901 will be subjected to the pressure from the inner wall of the snap-fit ​​groove 702, causing it to deform along its bending direction until the outer wall of the curved "C"-shaped plastic plate part on the second frame 901 is pushed into the groove with a curved semi-circular shape symmetrically arranged in the middle of the inner walls on both sides of the snap-fit ​​groove 702. At this point, the installation is complete.
