Description

Technical Field

[0001] This utility model relates to the technical field of waist-piercing bags, and in particular to an integrated waist-piercing bag with segmented pressure measurement. Background Technology

[0002] In clinical medicine, lumbar puncture is an important and commonly used diagnostic and therapeutic procedure, playing a crucial role, especially in the diagnosis of neurological diseases. For example, it is used to measure intracranial pressure and collect cerebrospinal fluid samples for laboratory analysis. Accurate measurement of intracranial pressure is of paramount importance for assessing a patient's condition, developing a treatment plan, and predicting prognosis.

[0003] Currently, traditional lumbar puncture kits have significant limitations in measuring intracranial pressure. The measuring tubes in traditional kits are of limited length, typically unable to directly cover intracranial pressure exceeding 330 mmHg. When dealing with patients with intracranial pressure exceeding this range, existing techniques often require complex and risky procedures. For example, medical staff may need to perform repeated procedures, adjusting or attempting multiple times to obtain a relatively accurate intracranial pressure value. This repetitive process not only increases patient discomfort but also prolongs the procedure time and may adversely affect the patient's condition. Furthermore, another common approach is to use external devices to extend the measuring tube's range; however, this external, non-integrated design introduces numerous problems.

[0004] On the one hand, regarding the risk of error, traditional methods for measuring high intracranial pressure often rely on indirect calculations to obtain the final result. This process involves multiple operational steps and human data reading and calculation, making it highly susceptible to human error. Differences in experience, skill level, and operating habits among different medical personnel can lead to deviations in measurement results, thus affecting the accurate assessment of the patient's condition. On the other hand, the risk of infection is also a serious problem with traditional methods. Repeatedly connecting non-sterile extension tubes and other devices significantly increases the chances of the entire measurement system coming into contact with the external environment. This not only disrupts the originally relatively sterile operating environment but also provides a pathway for pathogens such as bacteria and viruses to invade, significantly increasing the risk of infection for patients. Once an infection occurs, it can trigger a series of serious complications, worsen the patient's condition, prolong hospitalization, and even threaten the patient's life. Utility Model Content

[0005] The purpose of this invention is to disclose a novel lumbar puncture bag that improves the accuracy and safety of intracranial pressure measurement.

[0006] To achieve the above objectives, this utility model discloses an integrated lumbar puncture kit for segmented pressure measurement, comprising: a disposable packaging bag; a sterile drape, the sterile drape being folded and placed inside the disposable packaging bag; a puncture needle assembly; and a segmented pressure measuring tube assembly, the segmented pressure measuring tube assembly comprising a first pressure measuring tube segment and an extended pressure measuring tube segment, the first pressure measuring tube segment and the extended pressure measuring tube segment being sealed together, the total length of the first pressure measuring tube segment and the extended pressure measuring tube segment after connection being not less than 450mm; the puncture needle assembly and the segmented pressure measuring tube assembly are placed alternately inside the disposable packaging bag.

[0007] By adopting the above scheme, the segmented pressure measuring tube assembly includes a first pressure measuring tube segment and an extended pressure measuring tube segment, with a total length of no less than 450mm after sealing connection. This significantly extends the effective measurement length of the pressure measuring tube, directly meeting the measurement needs for high intracranial pressure and avoiding the inconvenience of repeated operations or external device connections due to insufficient tube length in traditional methods. Because the pressure measuring tube is a segmented, connectable, integrated structure, complex indirect calculations are unnecessary during measurement; intracranial pressure values ​​can be obtained directly from the tube readings. This greatly reduces the probability of human error, improves the accuracy of intracranial pressure measurement, and helps doctors more accurately assess the patient's condition. The sealed connection between the first and extended pressure measuring tube segments avoids repeated operations involving non-sterile external devices. The entire pressure measuring system is relatively independent and sterile within a disposable packaging bag, reducing contact with the external environment and effectively maintaining the sterility of the operating environment. This significantly reduces the risk of infection for patients and ensures their medical safety.

[0008] Furthermore, the first pressure measuring tube segment includes a first tube segment and a second tube segment. One end of the first tube segment is vertically and sealed to one end of the second tube segment. The other end of the first tube segment is provided with a male Luer connector for connecting to the puncture needle assembly. The other end of the second tube segment is provided with a female Luer connector for connecting to the extended pressure measuring tube segment.

[0009] The above solution provides significant convenience during installation and use. The vertical connection method makes operation easier even in limited spaces.

[0010] Furthermore, the two ends of the extended pressure measuring tube section are respectively provided with an extended tube Luer male connector and an extended tube Luer female connector, the extended tube Luer male connector being used to communicate with the second tube Luer female connector.

[0011] By adopting the above scheme, Luer male connectors and Luer female connectors are respectively installed at both ends of the extended pressure measuring tube section, and the Luer male connector can be connected to the Luer female connector of the second tube. This design gives the pressure measuring tube great flexibility.

[0012] Furthermore, the first pipe segment and the second pipe segment are integrally formed.

[0013] By adopting the above solution, problems such as pipe breakage and separation caused by insufficient strength of the connection parts can be effectively avoided.

[0014] Furthermore, the first pressure measuring tube segment is provided with a first scale along its length, and the value range of the first scale is 0mm-300mm.

[0015] By adopting the above method, intracranial pressure values ​​within this common range can be displayed directly and clearly. Medical staff can quickly and accurately obtain measurement results without additional calculations or the use of other tools, thus meeting the basic needs of daily clinical diagnosis and treatment.

[0016] Furthermore, the extended pressure measuring tube section is provided with a second scale along its length, and the value range of the second scale is 300mm-450mm.

[0017] By adopting the above method, medical staff no longer need to perform complex calculations or conversions; they can simply read the scale values ​​on the two pressure measurement tubes and add them together to obtain an accurate intracranial pressure value. This greatly simplifies the operation process, reduces human error, and improves measurement efficiency.

[0018] Furthermore, when the extended pressure measuring tube section is sealed and connected to the first pressure measuring tube section, the first scale and the second scale are collinear and continuously arranged.

[0019] By adopting the above approach, the continuous scale makes it much easier for medical staff to record intracranial pressure data. They only need to record the single scale value where the fluid level is located, instead of separately recording the values ​​on the first and extended pressure measurement sections, and then performing complex calculations and integration. This not only reduces recording time but also lowers the risk of data deviation due to recording errors, improving the efficiency and accuracy of medical work.

[0020] Furthermore, the joint of the puncture Luer male head, the second tube Luer female head, the expansion tube Luer male head, and the expansion tube Luer female head is provided with a frosted surface, and the friction coefficient of the frosted surface is ≥0.4.

[0021] By adopting the above solution, the friction between the components at the joint can be increased, making them less prone to relative slippage. Even under certain external forces, the joint can maintain a tight connection, ensuring the normal operation of components such as the pressure gauge.

[0022] Furthermore, a circular puncture window with a diameter of 10 cm is provided in the center of the sterile drape.

[0023] By adopting the above solution, a clear and defined operating area is provided for medical staff; it helps them quickly locate the puncture site in the center of the drape, avoiding blindly searching and adjusting the position on the drape, and greatly improving the efficiency and accuracy of the operation.

[0024] Furthermore, a line connecting the midline of the spine and the highest point of the iliac crest is provided perpendicularly through the center of the puncture window.

[0025] By adopting the above method, a natural coordinate system can be used to help medical staff determine the insertion angle of the puncture needle. During the puncture, medical staff can adjust the vertical angle of the puncture needle according to the direction of the midline of the spine, and adjust the horizontal angle of the puncture needle according to the direction of the line connecting the highest points of the iliac crests, so that the puncture needle can reach the target site more accurately and improve the success rate of the puncture.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional lumbar puncture kits have limited manometer length, making it difficult to directly cover cases of high intracranial pressure. This new lumbar puncture kit features a segmented manometer assembly, consisting of a first manometer segment and an extended manometer segment connected in a sealed manner, with a total length of no less than 450mm. This significantly extends the effective measurement length of the manometer, directly meeting the measurement needs for high intracranial pressure and avoiding measurement limitations caused by insufficient manometer length. 2. Traditional methods for measuring high intracranial pressure often rely on indirect calculations, involving multiple operational steps and human data reading and calculation, which are prone to human error. This lumbar puncture kit features a segmented, connectable, integrated pressure measurement tube. During measurement, no complex indirect calculations are required; the intracranial pressure value can be obtained directly from the pressure measurement tube reading, significantly reducing the probability of human error and helping doctors to more accurately assess the patient's condition. 3. Traditional methods involve repeatedly connecting non-sterile extension tubes and other devices, increasing the chances of the measurement system coming into contact with the external environment, compromising the aseptic operating environment, and increasing the risk of infection for patients. In contrast, this lumbar puncture kit features a sealed connection between the first and extended pressure measurement tube sections, avoiding the need for repeated connection of non-sterile devices. The entire pressure measurement system remains relatively independent and sterile within a disposable packaging bag, reducing contact with the external environment, effectively maintaining the aseptic nature of the operating environment, significantly reducing the risk of infection for patients, and ensuring their medical safety. 4. Traditional methods for measuring high intracranial pressure are complex, potentially requiring multiple adjustments or attempts, and may involve steps such as connecting external devices. This lumbar puncture kit features a simple, integrated segmented manometer assembly, making the measurement process easier and faster. Medical staff no longer need to perform complex procedures, enabling more efficient intracranial pressure measurement and improving work efficiency. The disposable packaging bag centrally houses the sterile drape, puncture needle assembly, and segmented manometer assembly, facilitating carrying and storage for medical staff. In clinical use, medical staff can quickly retrieve the necessary items from the packaging bag without needing to prepare additional parts, saving preparation time and improving emergency response capabilities.

[0035] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0036] See Embodiment 1 of this utility model. Figures 1 to 3 As shown, an integrated lumbar puncture kit with segmented pressure measurement is provided, including a disposable packaging bag 1, a sterile drape 2, a segmented pressure measurement tube assembly 3, and a puncture needle assembly 4. The disposable packaging bag 1 is made of medical-grade composite film material, and sterilely encapsulates the folded sterile drape 2, puncture needle assembly 4, and segmented pressure measurement tube assembly 3 inside. Optionally, it can also be equipped with some sterile cotton balls and test tubes. The puncture needle assembly 4 includes a needle and a needle core. This embodiment 1 does not impose too many restrictions on the puncture needle assembly 4 and can be replaced according to actual needs. Optionally, the puncture needle assembly 4 and the segmented pressure measurement tube assembly 3 are placed alternately inside the disposable packaging bag 1 to avoid collision.

[0037] The segmented pressure measuring tube assembly 3 includes a first pressure measuring tube segment 31 and an extended pressure measuring tube segment 32. The first pressure measuring tube segment 31 and the extended pressure measuring tube segment 32 are sealed together. The first pressure measuring tube segment 31 includes a first tube segment 311 and a second tube segment 312. One end of the first tube segment 311 and one end of the second tube segment 312 are vertically and sealed together. In some embodiments, the first tube segment 311 and the second tube segment 312 are integrally formed, which can effectively avoid problems such as tube breakage and separation due to insufficient strength of the connection. The first tube segment 311 and the second tube segment 312 are made of medical-grade PVC with a light transmittance ≥90%. The other end of the first tube segment 311 is provided with a male Luer connector 3111 for connecting to the puncture needle assembly 4, and the other end of the second tube segment 312 is provided with a female Luer connector 3121 for connecting to the extended pressure measuring tube segment 32. The first pressure measuring tube section 31 is provided with a first scale 313 along its length direction, that is, the second tube section 312 is provided with a first scale 313. The value range of the first scale 313 is 0mm-300mm, and it is laser etched with a main scale spacing of 10mm.

[0038] The extended pressure testing tube section 32 is provided with an extended tube Luer male connector 321 and an extended tube Luer female connector 322 at both ends. The extended tube Luer male connector 321 is used to communicate with the second tube Luer female connector 3121. The design of providing extended tube Luer male connector 321 and extended tube Luer female connector 322 at both ends, and allowing the extended tube Luer male connector 321 to communicate with the second tube Luer female connector 3121, gives the pressure testing tube great flexibility. The extended pressure testing tube section 32 has a second scale 323 along its length, with a numerical range of 300mm-450mm. This scale is also laser-etched, with a main scale spacing of 10mm. In some embodiments, a baseline can be set at 300mm of the extended pressure measuring tube segment 32, and a Next arrow marker can be set at 300mm of the first tube segment 311. This ensures that when the extended pressure measuring tube segment 32 is sealed to the first pressure measuring tube segment 31, the first scale 313 and the second scale 323 are collinear and continuously aligned. This arrangement allows medical personnel to obtain accurate intracranial pressure values ​​simply by reading and adding the scale values ​​from the two pressure measuring tube segments, eliminating the need for complex calculations or conversions. This significantly simplifies the operation, reduces human error, and improves measurement efficiency. The continuous scale makes recording intracranial pressure data more convenient for medical personnel. They only need to record the single scale value where the fluid level is located, instead of separately recording the values ​​on the first pressure measuring tube segment 31 and the extended pressure measuring tube segment 32, followed by complex calculations and integration. This not only reduces recording time but also lowers the risk of data deviation due to recording errors, improving the efficiency and accuracy of medical work.

[0039] The quick connection between the first pressure measuring tube segment 31 and the extended pressure measuring tube segment 32 allows for intracranial pressure measurement within the range of 0mm-450mm, meeting most practical needs. In other embodiments, the length of the extended pressure measuring tube segment 32 can be increased, making the total length after assembly with the first pressure measuring tube segment 31 greater than 450mm. The segmented pressure measuring tube assembly 3 includes the first pressure measuring tube segment 31 and the extended pressure measuring tube segment 32, and the total length after their sealed connection is not less than 450mm, significantly extending the effective measurement length of the pressure measuring tube. This directly meets the measurement needs for high intracranial pressure, avoiding the inconvenience of repeated operations or external devices required due to insufficient tube length in traditional methods. Since the pressure measuring tube is a segmented and connectable integrated structure, complex indirect calculations are not required during measurement; the intracranial pressure value can be obtained directly from the reading of the pressure measuring tube, greatly reducing the probability of human error and improving the accuracy of intracranial pressure measurement. This helps doctors to more accurately assess the patient's condition. The sealed connection between the first pressure measuring tube segment 31 and the extended pressure measuring tube segment 32 avoids the need for repeated external non-sterile device operations. The entire pressure measurement system is relatively independent and sterile within a disposable packaging bag 1, reducing the chance of contact with the external environment and effectively maintaining the sterility of the operating environment. This significantly reduces the risk of infection for patients and ensures their medical safety.

[0040] In some embodiments, the joints of the puncture Luer male connector 3111, the second tube Luer female connector 3121, the expansion tube Luer male connector 321, and the expansion tube Luer female connector 322 are provided with a frosted surface, the coefficient of friction of which is ≥0.4. This increases the friction between the components at the joint, making them less prone to relative slippage. Even under certain external forces, the joints can maintain a tight connection, ensuring the normal operation of components such as the pressure measuring tube. It should be noted that the interface pipe diameter tolerance is ≤±0.1mm to avoid liquid column fluctuations.

[0041] In this embodiment 1, a circular puncture window 21 with a diameter of 10cm is provided in the center of the sterile drape 2, providing medical staff with a clear and defined operating area. This helps medical staff quickly locate the puncture site in the center of the drape, avoiding blindly searching and adjusting the position on the drape, greatly improving the efficiency and accuracy of the operation. A line 23 connecting the midline of the spine 22 and the highest point of the iliac crest is set through the center, with the intersection marked as L4 horizontally. This can serve as a natural coordinate system to help medical staff determine the insertion angle of the puncture needle. During the puncture, medical staff can adjust the vertical angle of the puncture needle according to the direction of the midline of the spine 22 and the horizontal angle of the puncture needle according to the direction of the line 23 connecting the highest points of the iliac crest, so that the puncture needle can reach the target site more accurately and improve the success rate of the puncture. Optionally, the midline 22 of the spine is marked with 0-30cm graduations and 1cm increments on both sides. The line connecting the iliac crests extends cephalad and caudate, marked with L1-L5 interspinous space markers, scaled proportionally to the average spacing of Asian adults. The puncture window 21 can also be covered with a transparent PE film to allow for palpation verification of the puncture point. Using the pre-printed line 23 connecting the highest points of the iliac crests and the midline 22 of the spine on the sterile drape 2, the level of the L4 vertebral body is quickly located. By palpation verification of the puncture point, it is ensured that the puncture needle accurately enters the target intervertebral space. The puncture window 21, centered on the center, combined with the perpendicular intersection of the midline 22 of the spine and the line connecting the iliac crests, forms a coordinate system to assist in adjusting the needle insertion angle and reduce puncture deviation.

[0042] The operation steps of this utility model are as follows: Open the disposable packaging bag 1, take out the sterile drape 2 and unfold it to cover the patient's lower back. Adjust the position of the drape so that the pre-printed line connecting the highest points of the iliac crest 23 is aligned with the patient's actual iliac crest, initially locating the L4 level. Palpate the interspinous space through the transparent PE membrane. If anatomical abnormalities are found, move along the midline of the spine 22 towards the cephalic / coccygeal side, and determine the L3-L4 or L4-L5 interspinous space according to the proportional scale. Mark the puncture point at the corresponding position of the puncture window 21. After routine disinfection and anesthesia, insert the needle along the marked point. After successful puncture, remove the needle core and confirm the outflow of cerebrospinal fluid. Rotate and lock the male Luer connector 3111 of the first pressure measuring tube segment 31 to the puncture needle interface. Vertically raise the pressure measuring tube and read the 0-300mm scale value directly after the liquid column stabilizes. Keep the first pressure measuring tube segment 31 connected. Take out the extended pressure measuring tube segment 32 and align the male Luer connector 321 of the extended tube with the female Luer connector 3121 of the second tube of the first segment. Rotate and lock it to ensure that the "NEXT" arrow coincides with the baseline. Continue to vertically raise the tube body. After the liquid column rises to the scale area of ​​the extended segment, read the final value directly. Disconnect the pressure measuring tube assembly and collect cerebrospinal fluid or administer drug treatment. Dispose of all components as medical waste.

[0043] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Traditional lumbar puncture kits have limited manometer length, making it difficult to directly cover cases of high intracranial pressure. However, the segmented manometer assembly 3 of this novel lumbar puncture kit, consisting of a first manometer segment 31 and an extended manometer segment 32 sealed together, has a total length of no less than 450mm. This significantly extends the effective measurement length of the manometer, directly meeting the measurement needs for high intracranial pressure and avoiding measurement limitations caused by insufficient manometer length. 2. Traditional methods for measuring high intracranial pressure often rely on indirect calculations, involving multiple operational steps and human data reading and calculation, which are prone to human error. This lumbar puncture kit features a segmented, connectable, integrated pressure measurement tube. During measurement, no complex indirect calculations are required; the intracranial pressure value can be obtained directly from the pressure measurement tube reading, significantly reducing the probability of human error and helping doctors to more accurately assess the patient's condition. 3. Traditional methods involve repeatedly connecting non-sterile extension tubes and other devices, increasing the chances of the measurement system coming into contact with the external environment, compromising the aseptic operating environment, and increasing the risk of infection for patients. In contrast, the first pressure measurement tube section 31 and the extended pressure measurement tube section 32 of this lumbar puncture kit are sealed together, avoiding the need for repeated connection of non-sterile devices. The entire pressure measurement system remains relatively independent and sterile within the disposable packaging bag 1, reducing contact with the external environment, effectively maintaining the sterility of the operating environment, significantly reducing the risk of infection for patients, and ensuring their medical safety. 4. Traditional methods for measuring high intracranial pressure are complex, potentially requiring multiple adjustments or attempts, and may involve steps such as connecting external devices. This lumbar puncture kit features a simple, integrated segmented manometer assembly 3, making the measurement process easier and faster. Medical staff no longer need to perform complex procedures, enabling more efficient intracranial pressure measurement and improving work efficiency. The disposable packaging bag 1 centrally houses the sterile drape 2, puncture needle assembly 4, and segmented manometer assembly 3, facilitating carrying and storage for medical staff. In clinical use, medical staff can quickly retrieve the necessary items from the packaging bag without needing to prepare additional components, saving preparation time and improving emergency response capabilities.
