Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical monitoring equipment technology, and in particular to a multimodal arterial blood pressure monitor connection cable and its components for connecting a monitor and an invasive blood pressure sensor. Background Technology
[0002] Invasive arterial blood pressure monitoring is a routine monitoring method for patients in wards, especially ICU wards. Current technology often connects pressure sensors to monitors via cables, thereby converting the body's vascular pressure into electrical waveform signals displayed on the monitor screen. This allows clinicians to more intuitively understand the patient's invasive blood pressure dynamics, making the monitoring accurate, safe, and convenient.
[0003] Currently, most mainstream blood pressure sensors on the market (such as Philips and Mindray) require dedicated extension cables. These extension cables have different connectors, necessitating the use of different interfaces for the connection cables connecting the blood pressure sensor and the monitor. For example, the interface for connecting to an Edwards connector requires an oval-shaped snap-fit Edwards connector (see [link to relevant documentation]). Figure 1 Edwards interface 4), the interface for connection with the Utah connector must be a push-pull Utah interface (see [reference]). Figure 1 The interface for connecting to the Abbott connector (see UTA interface 3) must be a pin-contact Abbott connector (see [link]). Figure 1 (Abbott interface 5). When patients move between different departments, connection cables and consumables need to be replaced repeatedly as needed. Since the above connection cables all adopt a "one-to-one" single-interface structure, the following problems exist when different single-interface cables are connected to the monitor: frequent plugging and unplugging on the monitor increases the risk of patient infection and signal interference (such as poor contact caused by plugging and unplugging), thereby increasing operational risks; different brands of cables need to be purchased repeatedly, resulting in high usage costs; a single replacement of the connection cable takes ≥12 minutes, making the replacement inefficient and affecting the timeliness of treatment for critically ill patients. Summary of the Invention
[0004] The purpose of this invention is to solve the above problems by providing a multimodal arterial blood pressure monitor connection cable and its components. The cable has a simple structure, is easy to use, and can be connected to multiple brands of invasive blood pressure sensors. After connection, the signal transmission is not distorted, thus improving the efficiency of clinical operation.
[0005] To achieve the above-mentioned objectives of this utility model, the multimodal arterial blood pressure monitor connection cable provided by this utility model includes: a cable body with a plug at one end for connecting to the sensor socket of a monitor; and three interface heads connected to the other end of the cable body for use with connectors of three types of arterial blood pressure sensors.
[0006] Preferably, the three interface heads are connected to the other end of the cable body via three sets of cables.

[0008] Alternatively, the three connectors can be connected to the other end of the cable body via an adapter structure.
[0009] Preferably, the adapter structure includes: an adapter with one end for connecting to the other end of the cable body; and three adapters detachably connected to the adapter, the three adapters having three corresponding interface heads.
[0010] Preferably, one end of the adapter is connected to the power ground wire and power output wire for transmitting electrical energy, and the signal output positive wire and signal output negative wire for transmitting blood pressure sensor data of the cable body, and the other end is provided with a plug interface.
[0011] Preferably, one end of the adapter is provided with four pins for plugging into the connector of the adapter to connect the power ground wire, the power output line, the positive signal output line, and the negative signal output line respectively, and the other end is provided with an interface head for use with the connector of the corresponding arterial blood pressure sensor.
[0012] Preferably, the three interface heads are Edwards interface head, Abbott interface head, and UTA interface head, respectively.
[0013] Preferably, the three interface heads can be any three of the following: Edwards interface, UTA interface, Abbott interface, BD interface, B. Braun interface, M&D interface, and Mindray interface.
[0014] In addition, this utility model also provides a multimodal arterial blood pressure monitor connection cable assembly, which includes: the multimodal arterial blood pressure monitor connection cable as described above; and fixing pads for fixing the three interface heads of the multimodal arterial blood pressure monitor connection cable.
[0015] Compared with the prior art, the multimodal arterial blood pressure monitor connecting cable and its components of this utility model have the following advantages:
[0016] 1. The multimodal arterial blood pressure monitor connection cable and components of this utility model have a simple structure and are easy to use.

[0024] like Figures 1-4 The figures show different structural diagrams and pin connection diagrams of the multimodal arterial blood pressure monitor connection cable of this utility model. As can be seen from the figures, the multimodal arterial blood pressure monitor connection cable of this utility model includes: a cable body 2 with a plug 1 at one end for connecting to the sensor socket of the monitor; and three interface heads 3, 4, and 5 connected to the other end of the cable body for use with the connectors of three types of arterial blood pressure sensors.
[0025] Among them, such as Figure 1 As shown, the three connectors 3, 4, and 5 can be connected to the other end of the cable body via three separate cable components, and as... Figure 2 As shown, each set of cables includes: a power ground wire 23 and a power output positive wire 24 for transmitting electrical energy, a signal output positive wire 22 and a signal output negative wire 21 for transmitting blood pressure sensor data, which are electrically connected to the cable body.
[0026] Alternatively, the three connectors can be connected to the other end of the cable body 2 via an adapter structure. For example... Figure 3 As shown, the adapter structure includes: an adapter 6, one end of which is used to connect to the other end of the cable body; and three adapters 7 detachably connected to the adapter, the three adapters having three corresponding interface heads 3, 4, and 5.
[0027] Among them, such as Figure 4 As shown, one end of the adapter is electrically connected to the power ground wire 23 and power output positive wire 24 of the cable body for transmitting electrical energy, and the signal output positive wire 22 and signal output negative wire 21 for transmitting blood pressure sensor data. The other end is provided with a plug interface, which has jacks a, b, c, and d that are electrically connected to the signal output negative wire 21, signal output positive wire 22, power ground wire 23, and power output positive wire 24 through printed circuits.
[0028] Each adapter has four pins (A, B, C, D) on one end for connecting to the adapter's connector, namely the negative signal output line, positive signal output line, power ground line, and positive power output line, respectively. The other end has an interface for use with the corresponding arterial blood pressure sensor. The structure of the connection between the adapter and the adapter can refer to the structure of existing multi-charge connectors, etc., and will not be described in detail here.
[0029] The three interface heads mentioned above are the Edwards interface head, Abbott interface head, and UTA interface head, which are existing technologies. Alternatively, the three interface heads mentioned above can be any three of the following: Edwards interface, UTA interface, Abbott interface, BD interface, B. Braun interface, Medtronic interface, and Mindray interface.
[0030] When designing, the adapter can be circular in shape (see reference). Figure 1 , Figure 2 The plug shape can also be elongated oval (see [link]). Figure 3 , Figure 4 It can also be in other shapes as described in the prior art. One end of the adapter, which is used to plug into the adapter, matches the shape and size of the adapter's plug interface, while the other end of the interface head adopts the structure of a different interface in the prior art, which will not be described in detail here.
[0031] This utility model's multimodal arterial blood pressure monitor connection cable has a simple structure and is easy to use. It can be connected to the interfaces of invasive blood pressure sensors from different brands, and the signal transmission is not distorted after connection. It solves the problem of having to repeatedly replace extension cables or consumables when patients are transferred between departments, saves costs, improves clinical operation efficiency, and improves the timeliness of treatment for critically ill patients.

The fixing pad is provided with a main body groove 81 for securing the cable body and grooves for securing other components such as… Figure 1 The three branch cables and three interface heads shown, connected to the main body groove in slots 82, 83, and 84, effectively prevent the interface heads from loosening when connected to invasive blood pressure sensors of different brands, thus effectively improving the stability of signal transmission. During manufacturing, the fixing pad can be made of rubber or other materials. In the design, Velcro or straps can be added to the fixing pad on both sides to secure it to the patient's bedside.
