Detailed Description
In the present application, connection is realized by wireless means, including various network devices, bluetooth devices, wireless transceiver devices with specific bands, and the like.
The present invention will be described by way of example with reference to the accompanying drawings in conjunction with the embodiments, it being understood that the embodiments and features of the embodiments of the present application may be combined with each other without conflict. In addition, the described embodiments are some, but not all, embodiments of the invention.
Fig. 1 shows an apparatus for medical injection comprising a pair of ultrasonic detection rings 101 and 102, a connector 103, and an ultrasonic control and processing device 100. The first ultrasonic detection ring 101 includes the indicator lamps 1,2 and 3 (three indicator lamps are shown here for illustration only, and more indicator lamps can be actually distributed according to the density of the blood vessels at the positions), the second ultrasonic detection ring 102 includes the indicator lamps 4,5 and 6, the first ultrasonic detection ring 101 and the second ultrasonic detection ring 102 are connected through the connecting pieces 103, the first ultrasonic detection ring 101 and the second ultrasonic detection ring 102 can slide along the connecting pieces 103 and 104, and a space is formed in the directions of the connecting pieces 103 and 104, the space is determined according to the straightness of the blood vessels at the positions of the first ultrasonic detection ring and the second ultrasonic detection ring, for example, the arm position (arm 10 in the drawing) with slightly lower straightness of the blood vessels, and the distance between the first ultrasonic detection ring 101 and the second ultrasonic detection ring 102 can be shortened as much as possible so as to more accurately position the blood vessels suitable for injecting blood.
Fig. 2 shows a cross-sectional view of the first ultrasonic detection ring 101, showing the indicator lamps 1,2,3, and the connectors 103 and 104. Each ultrasonic testing ring includes a plurality of ultrasonic transmitters and a plurality of ultrasonic receivers (not shown). The upper half 105 (first annular section) of the first ultrasonic detection ring 101 is arranged with ultrasonic transmitters, ultrasonic receivers and indicator lamps 1,2,3 distributed circumferentially along the upper half 105 of the first ultrasonic detection ring. The lower half 106 (second annular section) of the first ultrasonic testing ring 101 includes an elastic connecting band for adaptively stretching and retracting according to the size of the patient's arm. The ultrasonic transmitter comprises a first ultrasonic transmitting device for generating high-frequency acoustic pulses and a second ultrasonic transmitting device for generating continuous waves. First ultrasound transmitting device the ultrasound transmitter is used to generate high frequency acoustic pulses for imaging tissue structures and organs. The second ultrasonic transmitting means transmits low frequency sound waves for measuring blood flow velocity and direction. The above description also applies to the second ultrasonic detection ring 102.
The ultrasonic control and processing apparatus 100 is connected to each ultrasonic detection ring for controlling the ultrasonic transmission and reception operation of each ultrasonic detection ring, and acquires ultrasonic data of each ultrasonic detection ring, and acquires characteristic data of a venous blood vessel including a distribution position of the venous blood vessel on an arm, a blood flow velocity, a blood flow direction, a blood vessel diameter, an intravascular structure, and the like of each blood vessel based on the ultrasonic data of each ultrasonic detection ring.
The ultrasonic data acquisition process is as follows: the ultrasonic transmitter transmits sound waves under the control of the ultrasonic control and treatment device 100, the transmitted sound waves propagating through biological tissue. The propagation speed of sound waves depends on the density and elasticity of the medium being measured. Different types of tissue have different effects on the propagation velocity of sound waves. When the acoustic wave encounters a boundary or region of different density inside the biological tissue, a portion of the acoustic wave is reflected back. The ultrasonic receiver is used for receiving the reflected sound wave signals. The ultrasonic control and processing device 100 records the time from the transmission of the acoustic wave to the reception of the acoustic wave ("ultrasonic propagation time"), which is the time of the ultrasonic wave round trip, divided by 2 to obtain a single pass time. By calculating the propagation time and velocity of the acoustic wave, the ultrasonic control and processing device can determine the distance that the acoustic wave signal reaches the interior of the object and returns after being transmitted from the ultrasonic transmitter. These distance information are used to generate a two-dimensional or three-dimensional image, wherein each pixel represents the acoustic reflection characteristics of a point inside the object. These images may be displayed on a computer screen for viewing by a doctor or operator, and the visualization link may be omitted. In medical ultrasound, the usual sonic velocities are: the speed of sound waves in soft tissue is about 1540 m/s and in bone is about 3200 m/s.
According to some embodiments of the present invention, the ultrasound control and processing apparatus 100 determines a first vein most suitable for intravenous injection in the first ultrasound detection loop and a second vein most suitable for intravenous injection in the second ultrasound detection loop according to the obtained feature data of the plurality of vein vessels at the position of the first ultrasound detection loop and the obtained feature data of the plurality of vein vessels at the position of the second ultrasound detection loop, and lights a first indicator lamp nearest to the first vein on the first ultrasound detection loop and a second indicator lamp nearest to the second vein on the second ultrasound detection loop, indicates a blood vessel suitable for injecting blood between the first ultrasound detection loop and the second ultrasound detection loop through the first indicator lamp and the second indicator lamp, and a medical staff can determine whether the two blood vessels correspond to the same blood vessel through naked eyes, if so, performs blood injection on the blood vessel. The ultrasonic control and processing apparatus 100 stores the positions of the respective indication lamps in advance, or stores the relative positional relationship of the indication lamps with respect to the plurality of ultrasonic transmitters in advance, or stores the relative positional relationship of the indication lamps with respect to the plurality of ultrasonic receivers in advance. After the first vein most suitable for intravenous injection in the first ultrasonic detection ring and the second vein most suitable for intravenous injection in the second ultrasonic detection ring are determined by the method, the positions of the most suitable for intravenous injection of the blood vessels relative to the indicator lamps can be correspondingly determined, and the indicator lamps near the positions of the most suitable for intravenous injection are controlled to be lightened.
According to other embodiments of the present invention, after determining the first vein most suitable for intravenous injection in the first ultrasonic detection ring and the second vein most suitable for intravenous injection in the second ultrasonic detection ring, the ultrasonic control and processing apparatus 100 may further compare the characteristic data of the first vein and the second vein to determine whether the first vein and the second vein correspond to the same vein, and if so, light a first indicator lamp on the first ultrasonic detection ring closest to the first vein, and light a second indicator lamp on the second ultrasonic detection ring closest to the second vein, and indicate a blood vessel between the first ultrasonic detection ring and the second ultrasonic detection ring suitable for blood injection through the first indicator lamp and the second indicator lamp. Therefore, the accuracy of blood vessel positioning can be further ensured, and the injection efficiency is improved.
In the above embodiment, if the ultrasound control and processing device 100 determines that the first venous blood vessel and the second venous blood vessel do not correspond to the same blood vessel, this may be due, for example, to the large magnitude of the deflection of the blood vessel bends, the blood vessel detected on the first detection loop not being detected on the second detection loop, resulting in the blood vessels detected on the two detection loops that are most suitable for injection being not the same blood vessel. At this time, the ultrasonic control and processing apparatus 100 emits a prompt tone to prompt the medical staff to shorten the distance between the first ultrasonic detection ring and the second ultrasonic detection ring so that two venous blood vessels at both ends of the same blood vessel can be simultaneously detected by the first ultrasonic detection ring and the second ultrasonic detection ring, and that the blood vessel most suitable for injection detected on the two detection rings is the same blood vessel.
According to some embodiments of the present invention, the ultrasound control and processing apparatus 100 may further be configured to acquire ultrasound data of each ultrasound detection ring and calculate, based on the ultrasound data, first relative feature data of a vein vessel where a first ultrasound detection ring is located and second relative feature data of a vein vessel where a second ultrasound detection ring is located, determine, based on the first relative feature data, a first vein vessel most suitable for intravenous injection in the first ultrasound detection ring and a second vein vessel most suitable for intravenous injection in the second ultrasound detection ring based on the second relative feature data, light a first indicator lamp on the first ultrasound detection ring closest to the first vein vessel, and light a second indicator lamp on the second ultrasound detection ring closest to the second vein vessel, and indicate, via the first indicator lamp and the second indicator lamp, a blood vessel between the first ultrasound detection ring and the second ultrasound detection ring suitable for blood injection. Medical staff can judge whether two blood vessels correspond to the same blood vessel or not through naked eyes, and if so, blood injection is carried out on the blood vessels. If not, shortening the distance between the first ultrasonic detection ring and the second ultrasonic detection ring so that two vein blood vessels at two ends of the same blood vessel can be detected by the first ultrasonic detection ring and the second ultrasonic detection ring at the same time. The relative characteristic data may be, for example, the relative ratio magnitude of the blood flow velocity, the blood flow direction, the blood vessel diameter, the intravascular structure, etc. between each blood vessel detected by the first ultrasonic detection ring.
The ultrasonic control and processing apparatus 100 determines a first vein most suitable for intravenous injection in the first ultrasonic detection ring and a second vein most suitable for intravenous injection in the second ultrasonic detection ring from the acquired feature data of a plurality of vein vessels at the position of the first ultrasonic detection ring and the acquired feature data of a plurality of vein vessels at the position of the second ultrasonic detection ring, compares the feature data of the first vein and the second vein to determine whether the first vein and the second vein correspond to the same vein, if so, lights a first indicator lamp (assumed to be indicator lamp 1 in the figure) on the first ultrasonic detection ring closest to the first vein, and lights a second indicator lamp (assumed to be indicator lamp 4 in the figure) on the second ultrasonic detection ring closest to the second vein, and indicates a blood vessel between the first ultrasonic detection ring and the second ultrasonic detection ring, which is suitable for blood injection, through the first indicator lamp and the second indicator lamp. If the characteristic data of the first vein blood vessel and the second vein blood vessel are compared, and then the first vein blood vessel and the second vein blood vessel are determined to be not corresponding to the same blood vessel, the distance between the first ultrasonic detection ring and the second ultrasonic detection ring is adjusted, so that the two vein blood vessels of the same blood vessel can be detected by the first ultrasonic detection ring and the second ultrasonic detection ring at the same time.
According to some embodiments of the invention, it is determined whether the first and second venous blood vessels correspond to the same blood vessel by calculating whether characteristic parameters of the first and second venous blood vessels match. For example, if the calculation determines that two blood vessels have similar blood flow velocity, blood flow direction, blood vessel diameter, intravascular structure, etc., the two blood vessels may be considered to correspond to the same blood vessel. The intravascular structures include, for example, a thrombus or plaque, and similar intravascular structures may indicate that the two vessels are from the same vessel.
According to some embodiments of the present invention, the ultrasonic control and processing device 100 may be arranged independently of the ultrasonic detection ring, and wirelessly control ultrasonic transmission and reception of the ultrasonic detection ring by bluetooth or the like, and acquire corresponding ultrasonic data, and the ultrasonic detection ring may wirelessly transmit the ultrasonic data to the ultrasonic control and processing device by bluetooth or the like after encoding the ultrasonic data, for example.
The invention can rapidly and accurately determine the most suitable blood vessel for injection, and medical staff can directly inject the most suitable blood vessel between the two ultrasonic detection rings, thereby improving the injection efficiency; in addition, the whole device belongs to portable and portable equipment, so that the device can be flexibly applied to various occasions.
Fig. 3 shows a flow chart of a method of using the device for medical injection based on fig. 1, according to some embodiments of the invention. The method comprises the following steps:
s1, adjusting a first ultrasonic detection ring and a second ultrasonic detection ring.
After the first ultrasonic detection ring 101 and the second ultrasonic detection ring 102 are worn on the arm of the patient, the interval between the first ultrasonic detection ring 101 and the second ultrasonic detection ring 102 is adjusted, for example, by relatively sliding the first ultrasonic detection ring 101 and/or the second ultrasonic detection ring 102 along the connectors 103 and 104 to adjust the interval to adapt to the straightness of the blood vessel at different injection positions.
S2, acquiring ultrasonic data.
The ultrasonic transmitter of the ultrasonic detection loop is controlled by the ultrasonic control and processing device 100 to transmit sound waves. The emitted sound waves penetrate the biological tissue and a portion is reflected back. The ultrasonic receiver of the ultrasonic detection ring is used for receiving the reflected ultrasonic wave. The ultrasonic control and processing equipment acquires ultrasonic data corresponding to ultrasonic waves in a wireless mode.
S3, acquiring characteristic data of vein blood vessels, and determining the blood vessels most suitable for injection.
The ultrasonic control and processing equipment acquires the characteristic data of the venous blood vessel at the position of each ultrasonic detection ring according to the ultrasonic data, wherein the characteristic data comprise the position, the blood flow speed, the blood flow direction, the blood vessel diameter, the intravascular structure and the like.
The ultrasonic control and processing equipment determines the most suitable blood vessel to be injected at the position of each ultrasonic detection ring according to the characteristic data.
According to some embodiments of the present invention, the ultrasound control and processing device 100 may also generate two-dimensional or three-dimensional images that are displayed on a computer screen for viewing by a doctor or operator. These images display tissue structure and vessel position and may also display information such as blood flow velocity.
S4, performing blood vessel matching and lighting an indicator lamp.
The ultrasonic control and processing device determines a first vein most suitable for intravenous injection in the first ultrasonic detection ring and a second vein most suitable for intravenous injection in the second ultrasonic detection ring according to the characteristic data of the vein. If they correspond to the same vessel, a first indicator light on a first ultrasonic testing ring closest to the first vein vessel is illuminated, and a second indicator light on a second ultrasonic testing ring closest to the second vein vessel is illuminated. The two indicator lights together indicate a blood vessel suitable for injecting blood. If they do not correspond to the same vessel (e.g., one of the vessels is not detected by the other ultrasound detection loop due to a large magnitude of vessel bending), an alert is sounded.
S5, adjusting the distance between the first ultrasonic detection ring and the second ultrasonic detection ring.
And according to the prompt tone of S5, adjusting the distance between the first ultrasonic detection ring and the second ultrasonic detection ring to ensure that the first vein most suitable for intravenous injection in the first ultrasonic detection ring and the second vein most suitable for intravenous injection in the second ultrasonic detection ring are detected by the two detection rings at the same time.
The use of this device may help medical professionals more accurately locate and select a blood vessel for injection, thereby improving the accuracy and efficiency of the injection.
In addition, the details described above with respect to fig. 1 and 2 may also be included herein, and are not repeated herein for simplicity. In addition, some of the above steps may be omitted, for example, in step S3, the medical staff may directly determine the blood vessel most suitable for injection according to the indicator light without referring to the ultrasound image on other displays.
The invention can rapidly and accurately determine the most suitable blood vessel for injection, and medical staff can directly inject the most suitable blood vessel between the two ultrasonic detection rings, thereby improving the injection efficiency; in addition, the whole device belongs to portable and portable equipment, so that the device can be flexibly applied to various occasions.
