Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical devices, in particular to an arterial blood pressure sensor fixing box and a pipeline arrangement method thereof. BACKGROUND

[0002] In the critical care scene such as ICU and CCU, arterial blood pressure monitoring is the core operation for evaluating the patient's circulation function, guiding fluid resuscitation and drug use. As the key equipment of the monitoring system, the stable operation and standard management of the arterial blood pressure sensor directly affect the accuracy of clinical diagnosis and treatment decision. However, the existing arterial blood pressure sensor is long-term limited by the defects of the fixing and pipeline management system in clinical application, which derives a series of problems such as high operation risk, large equipment loss and rising medical cost. Among them, the arterial blood pressure monitoring system needs to be connected with multiple functional pipelines simultaneously, including a pressure catheter for real-time pressure monitoring, a signal line for transmitting monitoring data, a special pipeline for assisting central venous pressure (CVP) measurement, and a flushing pipeline for preventing pipeline blockage.

[0003] In the existing clinical scene, these pipelines lack special classification constraint structure and are in a disordered stacking state. The pressure catheter and the signal line are prone to be tangled and bent due to pulling, which not only may block the pressure catheter and affect the accuracy of monitoring data, such as abnormal blood pressure fluctuation, but also increases the operation difficulty of medical staff. In the case of emergency adjustment, such as patient turning over and equipment shifting, the tangled pipeline is easy to be pulled by mistake, which may cause monitoring interruption or pipeline damage, and indirectly increase the risk of diagnosis and treatment delay. Clinical operation statistics show that about 35% of arterial blood pressure monitoring data abnormal events are directly related to pipeline blockage or signal interference caused by pipeline tangling, which seriously affects the evaluation of the circulation state of critically ill patients.

[0004] In addition, in order to maintain the smoothness of the arterial blood pressure monitoring pipeline, a syringe is needed for regular pipeline flushing, such as saline flushing. The existing syringes are mostly fixed beside the sensor by simple buckles or adhesive tapes. Such fixing method has poor stability. For example, in the ICU environment, the vibration of the equipment, such as the operation of the breathing machine and the adjustment of the bed, may cause the syringe to fall off. The fallen syringe not only may contaminate the pipeline interface, but also may interrupt the flushing operation, increase the risk of pipeline thrombosis, and increase the burden of medical resources.

When one component is considered to be arranged on another component, it can be directly arranged on another component or there can be a component arranged in the middle.

[0042] In addition, the terms such as long, short, inside, outside, etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application, and does not indicate or imply that the device or element referred to must have this particular orientation, be constructed in a particular orientation, and cannot be understood as a limitation of the present application.

[0043] The present application will be described in detail below in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present application, and the changes made by those of ordinary skill in the art in structure, method, or function based on these embodiments are all included within the scope of protection of the present application.

[0044] Referring to Figs. 1-3 The arterial blood pressure sensor fixing box provided in the embodiment includes a limiting mechanism arranged on the box body 1.

[0045] The limiting mechanism includes a pipeline hole 111 arranged at one end of the box body 1 for pressure monitoring and a signal hole 121 arranged at the other end of the box body 1 for pipeline flushing. The top surface of the box body 1 is further provided with a pipeline hole 131 for CVP measurement and a fixing hole 132 for fixing a syringe.

[0046] The diameter of the pipeline hole 111 is 0.4-0.6 cm; preferably 0.5 cm.

[0047] The diameter of the signal hole 121 is 0.8-1.2 cm; preferably 1 cm.

[0048] The diameter of the pipeline hole 131 is 0.4-0.6 cm; preferably 0.5 cm.

[0049] The diameter of the fixing hole 132 is 1.3-1.7 cm; preferably 1.5 cm.

[0050] The center distance between the pipeline hole 131 and the fixing hole 132 is 3.2-3.8 cm; preferably 3.5 cm.

[0051] Specifically, before operation, first check the appearance state of the box body 1 polycarbonate transparent hexagonal, confirm that the box body has no cracks, the wall thickness is uniform; the standard 1.2 mm ± 0.2 mm, the visible light transmittance is normal > 90%, which can be judged by observing whether the box is clear, to avoid affecting the subsequent fixing stability due to the damage of the box body.

[0052] Specifically, the key components and the hole positions are checked. The hole wall of the pipeline hole 111 with a diameter of 0.5 cm, the signal hole 121 with a diameter of 1 cm, the pipeline hole 131 with a diameter of 0.5 cm, and the fixing hole 132 with a diameter of 1.5 cm are free of burrs. The annular silica gel gasket nested in the inner wall of the fixing hole 132 has a trapezoidal cross section, an inner diameter of 1.2 cm ± 0.1 cm, and no shedding or deformation, so as to ensure that it can be normally compressed axially with a compression amount of 0.3-0.5 mm. The rotating pin mechanism 14 is checked. The base and the box body are injection molded without looseness. The U-shaped pin is hingedly flexible. The locking buckle at the free end can be normally buckled to avoid falling off during use of the fixing box. The rotating pin mechanism 14, the base and the box body are injection molded without looseness. The U-shaped pin is hingedly flexible. The locking buckle at the free end all adopts the U-shaped pin of the prior art. This embodiment does not describe too much, and the drawings also do not show too much.

[0053] Specifically, according to the type of the arterial blood pressure sensor, it is confirmed that the pressure catheter diameter is adapted to the pipeline hole 111 (0.4-0.6 cm), and the signal line diameter is adapted to the signal hole 121 (0.8-1.2 cm). It is confirmed that the CVP measuring pipeline diameter is adapted to the pipeline hole 131 (0.4-0.6 cm), and the syringe neck diameter is adapted to the fixing hole 132 (1.3-1.7 cm). If the syringe neck is slightly thick, the elastic compression of the silica gel gasket can achieve tight clamping without forcibly extruding and damaging the components.

[0054] The inner wall of the fixing hole 132 is nested with an elastic limiting piece.

[0055] The elastic limiting piece is an annular silica gel gasket.

[0056] The cross section of the annular silica gel gasket is a trapezoidal structure, and the inner diameter is 1.2 cm ± 0.1 cm. It can be axially compressed and deformed by 0.3-0.5 mm.

[0057] Specifically, the installation operation of the arterial blood pressure sensor and the pipeline is as follows:

[0058] Hold the box body 1 at the bottom with one hand, and take out the arterial blood pressure sensor body with the other hand. Place it stably into the inner cavity of the box body 1 (the inner cavity size is adapted to the sensor to avoid shaking of the sensor in the box): Ensure that the pressure catheter interface and the signal interface of the sensor are directed towards the corresponding hole positions of the box (the pressure catheter is directed towards the pipeline hole 111, and the signal line is directed towards the signal hole 121) to facilitate subsequent pipeline connection and reduce pipeline bending.

[0059] Hold the pressure catheter end of the arterial blood pressure sensor (away from the sensor body end), align it with the pipe hole 111 (diameter 0.5 cm) at one end of the box body 1, slowly pass through the hole, and the length of the pipe hole is usually 10-15 cm, which can meet the subsequent pressure monitoring connection requirements (usually 10-15 cm, to avoid pulling the sensor too short), and avoid excessive bending of the catheter (to prevent catheter blockage or damage). Hold the signal line connector of the sensor (if the connector is connected, confirm that the connector size is suitable for the signal hole 121, and remove the connector sheath first), align the signal hole 121 (diameter 1 cm) at the other end of the box body 1, and smoothly pass through the hole, and then arrange the signal line to naturally hang down to avoid winding on the pressure catheter.

[0060] Take out the CVP measurement pipeline, align one end of the pipeline with the pipeline hole 131 (diameter 0.5 cm) on the top surface of the box body 1, slowly pass through the hole, and the other end is connected to the CVP monitoring device (such as a pressure monitor), and ensure that the pipeline is not twisted after passing through the hole, and there is no obvious gap between the hole and the pipeline (to avoid pipeline shaking).

[0061] Specifically, take out the matching syringe (usually a syringe for flushing or sampling), hold the syringe barrel, and align the neck of the syringe (near the needle seat) with the fixing hole 132 (diameter 1.5 cm) on the top surface of the box body 1. Gently press the neck into the annular silicone gasket on the hole wall: the silicone gasket tightly wraps the neck of the syringe through axial compression (0.3-0.5 mm) to achieve fixation, ensuring that the syringe does not fall off when placed vertically or slightly inclined, and checking whether the syringe can be slightly removed after fixation (to facilitate subsequent replacement and avoid damaging the gasket due to excessive tightness).

[0062] The box body 1 is integrated with a rotating pin mechanism 14.

[0063] The rotating pin mechanism 14 includes a base that is injection molded with the box body 1, and a U-shaped pin is hinged on the base, and a locking buckle is provided on the free end of the U-shaped pin.

[0064] Specifically, the box body 1 is made of transparent polycarbonate material in the shape of a hexagon, and the wall thickness is 1.2 mm+0.2 mm.

[0065] The visible light transmittance of the box body 1 is >90%.

[0066] Preferably, the size of the box body 1 ranges from 14-18 cm in length, 8-12 cm in width, and 1.5-2.5 cm in height.

[0067] The inner cavity of the box body 1 is provided with an arterial blood pressure sensor.

[0068] Specifically, the rotating pin mechanism uses:

[0069] According to the clinical operation scene (such as bedside, beside the monitor), adjust the angle of the rotating pin mechanism 14: pinch the middle part of the U-shaped pin, rotate around the base hinge point to the appropriate angle (usually 90° or 120° with the box 1, convenient for fixing), align the free end of the U-shaped pin with the fixed carrier (such as the bed rail, monitor support, medical staff uniform pocket edge), gently buckle, make the locking buckle tightly clamp the carrier, complete the position fixing of the fixed box. After fixing, pull the box 1 gently, confirm that the pin is not loose and the locking buckle is not fallen off, to avoid the fixed box falling during use; if you need to adjust the position, press the locking buckle to open the pin, adjust the angle again and fix it.

[0070] Specifically, when selecting a fixed position, the following requirements need to be met:

[0071] ① The box 1 remains horizontal to avoid pressure monitoring errors caused by the inclination of the sensor body;

[0072] ② No excessive pulling of each pipeline (pressure conduit, signal line, CVP pipeline), leaving a certain activity allowance (avoiding pulling the pipeline when the patient turns over or the equipment moves);

[0073] ③ The box 1 is away from the liquid source (such as below the infusion bottle, beside the sink), to prevent liquid from splashing into the box and damaging the sensor;

[0074] ④ The transparent box 1 needs to be directed towards the direction convenient for the medical staff to observe (such as directly opposite the side of the monitor screen), to facilitate real-time viewing of the sensor status.

[0075] Specifically, after all the pipelines are installed, the pipelines are combed:

[0076] ① Respectively arrange the pressure conduit, signal line, and CVP pipeline to ensure that each pipeline extends in the fixed direction without crossing and winding (the direction can be combed according to the pipeline hole 111 pipeline to the left, signal hole 121 line to the right, and pipeline hole 131 pipeline to the front);

[0077] ② Check the contact between each pipeline and the hole position. If there is a risk of pipeline wear (such as slightly rough edges of the hole wall), a circle of medical tape can be wrapped around the contact point (to avoid covering the pipeline scale or affecting the flow of liquid);

[0078] ③ After fixing the syringe, ensure that the plunger is directed towards the direction convenient for operation (such as upwards or sideways), to facilitate subsequent pipeline flushing or sampling operation.

[0079] Specifically, check the fixed box status every 1-2 hours:

[0080] ① Observe whether the sensor in the box is normal (no alarm indicator light, no liquid leakage);

[0081] ② Check whether each pipeline is unobstructed (no bending, blockage), whether the syringe in the fixing hole 132 is stable (no looseness, falling);

[0082] ③ Confirm the fixing state of the rotating pin mechanism 14, and re-engage in time if there is looseness.

[0083] Specifically, if the surface of the box body 1 is contaminated with dust or liquid, use clean medical gauze to dip a small amount of normal saline or 75% medical alcohol and gently wipe (avoiding alcohol penetration into the box). After wiping, dry and keep the box transparent and clear, which is convenient for observing the internal sensor state.

[0084] Specifically, if the annular silicone gasket is aged or deformed (such as unable to rebound after compression), or the hole position is damaged, the fixing box or the corresponding accessories (such as replacing the silicone gasket alone) need to be replaced in time to avoid affecting the fixing effect of the pipeline; if the locking buckle of the rotatable pin is damaged, the pin mechanism needs to be replaced to ensure the stability of the fixing box position.

[0085] Specifically, when the fixing box needs to be removed, operate in the order of outside first and then inside:

[0086] ① First, pull out the syringe in the fixing hole 132, then disconnect the CVP pipeline from the monitoring equipment, and pull out the CVP pipeline from the pipeline hole 131;

[0087] ② Disconnect the signal line from the monitor, and pull out the signal line from the signal hole 121;

[0088] ③ Disconnect the pressure conduit from the pressure monitoring equipment, and pull out the pressure conduit from the pipeline hole 111;

[0089] ④ Finally, take out the arterial blood pressure sensor body in the box to avoid damaging the sensor by pulling the pipeline.

[0090] Specifically, after disassembly is completed, clean the fixing box:

[0091] ① Wipe the inside and outside of the box body with dry gauze to ensure that there is no liquid residue;

[0092] ② Check whether the annular silicone gasket and the rotating pin mechanism 14 are intact, and clean thoroughly if there are stains;

[0093] ③ Put the fixing box into a special storage bag or sterilization box (avoid mixing with sharp instruments to prevent the box from being scratched), and store it in a dry and ventilated environment for easy next use.
