Description

Technical Field

[0001] This utility model belongs to the field of medical and nursing device technology, and specifically relates to a neck internal jugular vein compression device. Background Technology

[0002] Currently, in clinical practice, patients with chronic subdural hematoma or effusion, or those with collapsed skull defects, require appropriate compression of the internal jugular vein in the neck during the perioperative period to increase intracranial venous pressure and promote brain re-expansion. Simultaneously, for some patients with normal or low-pressure hydrocephalus after external ventricular drainage or shunt, appropriate compression of the internal jugular vein in the neck is also necessary to promote the recovery of brain tissue compliance and cerebrospinal fluid drainage or shunt, thereby alleviating hydrocephalus symptoms. However, current clinical nursing procedures lack specialized instruments for compressing the internal jugular vein in the neck. Typically, an elastic bandage is directly wrapped around the patient's neck, applying pressure to the vein through the elasticity of the bandage. However, this method cannot provide a precise quantitative indicator of compression pressure. For conscious patients, the appropriateness of the pressure is often judged by their own senses, and for comatose patients, there is even less basis for judgment. Therefore, this method cannot allow medical staff to select compression pressure using quantitative indicators, nor is it conducive to assessing the impact of different compression pressures on patient recovery.

[0003] Based on the above situation, it is necessary to design a neck internal jugular vein compression device that can at least solve some of the above problems and defects. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model proposes a neck internal jugular vein compression device. It has a simple structure and is easy to use. It can increase intracranial venous pressure by compressing the neck internal jugular vein, thereby promoting brain re-expansion, cerebrospinal fluid drainage or diversion, or the recovery of brain tissue compliance. At the same time, it can accurately quantify the pressure index applied to the internal jugular vein, which is convenient to apply different compression pressures according to the needs of different patients.

[0005] The technical solution of this utility model is:

[0006] This utility model proposes a neck internal jugular vein compression device, including a left strip flexible band and a right strip flexible band, wherein the two ends of the left strip flexible band are detachably connected to the two ends of the right strip flexible band respectively.

[0007] The left strip flexible belt is provided with a left airbag facing inward, and the right strip flexible belt is provided with a right airbag facing inward. The left airbag and the right airbag are arranged opposite each other and are both connected to the inflation pipeline.

[0008] Preferably, both the left and right airbags are longitudinally arranged strip-shaped airbags, and both the left and right airbags are low-pressure, high-capacity airbags.

[0009] Preferably, the outer side of the left strip flexible band is provided with a left positioning mark corresponding to the left airbag, and the outer side of the right strip flexible band is provided with a right positioning mark corresponding to the right airbag.

[0010] Preferably, the inflation line is a three-way line equipped with a three-way valve, and two of the lines are respectively connected to the left airbag and the right airbag, while the other line is equipped with a one-way valve at its end.

[0011] Preferably, the one-way valve includes a valve body, and a blocking block and a blocking spring movably disposed within the valve body;

[0012] The valve body is provided with an interface cavity, a sealing cavity, and a buffer cavity connected in sequence. The interface cavity is located near the external interface end of the valve body. The sealing spring is located in the sealing cavity. The sealing block is movably located in the interface cavity and its part extends into the sealing cavity and abuts against the sealing spring.

[0013] Preferably, the blocking block includes a pressing block and a sealing plate connected by a central column, wherein the pressing block is movably disposed within the interface cavity, and the sealing plate is movably disposed within the blocking cavity;

[0014] The valve body is provided with an air guide hole that connects the interface cavity and the sealing cavity. The cross-sectional area of ​​the pressing block and the sealing plate is larger than the cross-sectional area of ​​the air guide hole, while the cross-sectional area of ​​the central column is smaller than the cross-sectional area of ​​the air guide hole.

[0015] Preferably, both ends of the left and right flexible strips are provided with matching snap fasteners or Velcro, and multiple sets of snap fasteners or Velcro are provided parallel to each other along the length direction of the left and right flexible strips.

[0016] This utility model has the following advantages and effects compared with the prior art:

[0017] (1) The left and right strip flexible bands are detachably connected at both ends. By adjusting the connection length and position of the two ends of the left and right strip flexible bands, the left and right airbags located inside them are aligned with the internal jugular vein in the patient's neck. This ensures that the left and right airbags are accurately applied to the internal jugular vein area of ​​the patient's neck and apply pressure to the internal jugular vein. It is also suitable for patients with different neck circumferences, and has strong practicality and wide applicability.

[0018] (2) The left and right airbags are arranged inward and connected by an inflation tube. The airbags can provide a pressure index that varies within a set pressure range to meet the different pressure requirements of different patients. At the same time, it is convenient to accurately quantify the pressure index, which is conducive to subsequent research to judge the impact of the pressure index on the patient's recovery.

[0019] (3) A three-way air-filled tubing with a three-way valve is used, which can be selected to pressurize only the left internal jugular vein, or only the right internal jugular vein, or pressurize both the left and right internal jugular veins simultaneously, according to clinical needs, to meet different clinical needs.

[0024] To enable those skilled in the art to better understand this utility model, it will now be further described in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of this utility model.

[0025] Example:

[0026] like Figures 1-3As shown, this utility model provides a neck internal jugular vein compression device, including a left strip flexible band 1 and a right strip flexible band 2. The two ends of the left strip flexible band 1 are detachably connected to the two ends of the right strip flexible band 2. Specifically, both ends of the left strip flexible band 1 and the right strip flexible band 2 are provided with matching snap fasteners or Velcro to secure them together and wrap around the neck area. The left strip flexible band 1 and the right strip flexible band 2 can be made of skin-friendly and breathable material to improve wearing comfort. Multiple sets of snap fasteners or Velcro are arranged parallel to each other along the length of the left strip flexible band 1 and the right strip flexible band 2 to adjust the overall wrapping length, thus adapting to patients with different neck circumferences.

[0027] refer to Figure 1 As shown, the left flexible strip 1 is equipped with a left airbag 11 facing inward, and the right flexible strip 2 is equipped with a right airbag 21 facing inward. The left airbag 11 and the right airbag 21 are arranged opposite each other and are both connected to the inflation tube 3, so that gas can be injected into the left airbag 11 and / or the right airbag 21 through the inflation tube 3 to provide pressure. It should be noted that since the internal jugular vein is not located on the exact left and right sides of the neck, but rather towards the anterior side of the neck, the left airbag 11 and the right airbag 21 are not located at the center of the length of the left flexible strip 1 and the right flexible strip 2, but are located near the anterior end of the left flexible strip 1 and the right flexible strip 2, specifically at 2 / 3 to 3 / 4 of the total length of the left flexible strip 1 and the right flexible strip 2.

[0028] In practical use, the left airbag 11 of the left flexible band 1 is placed directly opposite the left internal jugular vein of the patient's neck, and the right airbag 21 of the right flexible band 2 is placed directly opposite the right internal jugular vein of the patient's neck. At this time, the left airbag 11 and the right airbag 21 are respectively directly opposite and abutting against the left and right internal jugular veins of the patient's neck. Then, the rear end and front end of the left flexible band 1 and the right flexible band 2 are connected in sequence with snaps or Velcro, so that the left airbag 11 and the right airbag 21 are tightly against the internal jugular veins on both sides of the patient's neck. Since both ends of the left flexible band 1 and the right flexible band 2 are adjustable, even for patients with different neck circumferences, the connection length and position of the two ends of the left flexible band 1 and the right flexible band 2 can be adjusted to ensure that the left airbag 11 and the right airbag 21 are directly opposite and abutting against the patient's internal jugular vein.

[0029] Furthermore, both the left airbag 11 and the right airbag 21 are longitudinally arranged strip-shaped airbags, and both the left airbag 11 and the right airbag 21 are low-pressure, high-volume airbags to avoid excessive pressure on the internal jugular vein and ensure safety during use. At the same time, the left airbag 11 is fixedly embedded inside the left strip flexible band 1, and the right airbag 21 is fixedly embedded inside the right strip flexible band 2.

[0030] Furthermore, a left positioning mark 12 corresponding to the left airbag 11 is provided on the outer side of the left strip flexible band 1, and a right positioning mark 22 corresponding to the right airbag 21 is provided on the outer side of the right strip flexible band 2. The left positioning mark 12 and the right positioning mark 22 make it easy to know and determine the specific position of the left airbag 11 and the right airbag 21, thereby reducing the difficulty of adjusting the position of the left airbag 11 and the right airbag 21.

[0031] Combination Figure 1 and Figure 2 As shown, the inflation line 3 is specifically a three-way line equipped with a three-way valve 4. Two of the lines are connected to the left airbag 11 and the right airbag 21, respectively, and the other line is equipped with a one-way valve 5 at its end. Since the three-way valve 4 is a mature existing technology in this field, its specific structure and principle will not be described in detail here. During use, existing inflation equipment can be connected to the one-way valve 5 to inject a set volume of gas into the left airbag 11 and / or the right airbag 21, while simultaneously monitoring the corresponding airbag pressures of the left airbag 11 and / or the right airbag 21. Gas injection stops once the airbag pressure reaches the set value. Specifically, in practical applications, a German VBM airbag pressure gauge connected to the one-way valve 5 can be used for inflation. In addition, it should be noted that in clinical applications, the three-way valve 4 can be adjusted to change the connection state of the inflation line 3 according to actual usage needs. For example, only the left balloon 11 can be inflated to pressurize only the left internal jugular vein in the neck, or only the right balloon 21 can be inflated to pressurize only the right internal jugular vein in the neck, or both the left balloon 11 and the right balloon 21 can be inflated simultaneously to pressurize both sides of the internal jugular vein in the neck.

[0032] like Figure 3 As shown, the one-way valve 5 includes a valve body 51 and a blocking block 52 and a blocking spring 53 movably disposed within the valve body 51. The valve body 51 is provided with an interface cavity 511, a blocking cavity 512, and a buffer cavity 513 connected in sequence. The interface cavity 511 is arranged near the external interface end of the valve body 51. The blocking spring 53 is disposed within the blocking cavity 512. The blocking block 52 is movably disposed within the interface cavity 511, and part of it extends into the blocking cavity 512 and abuts against the blocking spring 53.

[0033] Specifically, the blocking block 52 includes a pressing block 522 and a sealing plate 523 connected by a central column 521. The pressing block 522 is movably disposed within the interface cavity 511, and the sealing plate 523 is movably disposed within the blocking cavity 512. The valve body 51 is provided with a vent hole 514 connecting the interface cavity 511 and the blocking cavity 512. The cross-sectional areas of the pressing block 522 and the sealing plate 523 are both larger than the cross-sectional area of ​​the vent hole 514, while the cross-sectional area of ​​the central column 521 is smaller than the cross-sectional area of ​​the vent hole 514. One end of the blocking spring 53 is fixedly disposed within the blocking cavity 512, and the other end... The end abuts against the sealing plate 523 of the sealing block 52, so that the sealing plate 523 abuts against the air guide hole 514 under the action of the sealing spring 53, thereby sealing the air guide hole 514 and preventing air leakage. At the same time, during the inflation process, the interface of the inflation device presses against the pressing block 522 of the sealing block 52, which compresses the sealing spring 53. The sealing plate 523 disengages from the air guide hole 514, connecting the interface cavity 511 and the sealing cavity 512 to achieve inflation. In addition, during the deflation process, the deflation operation can be completed simply by pressing the pressing block 522. The principle is the same as above and will not be repeated here.

[0034] In summary, the internal jugular vein compression device provided by this utility model has a simple structure and is easy to use. It can increase intracranial venous pressure by compressing the internal jugular vein in the neck, thereby promoting brain re-expansion, drainage or diversion of cerebrospinal fluid, or recovery of brain tissue compliance. At the same time, it can accurately quantify the pressure index applied to the internal jugular vein, making it convenient to apply different compression pressures according to the needs of different patients.

[0035] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
