1) Communication Script: Transforming “Unknown” into “Knowable”

The patient’s tension mainly stems from the fear of unknown equipment and processes. Your words are the first line of defense against fear.

1. Popularize the introduction of the equipment (avoid using medical terms) :

Don’t say: “We are now using an ultrasound venous imager to find your blood vessels.”

It can be said: “Let’s use this’ vascular fluoroscopy instrument ‘to take a look and see which of your blood vessels is the most obedient. We’ll choose that one.” Or “This is a ‘vascular navigation’ that can help us see more clearly and make the puncture go more smoothly.”

Principle: Comparing high-tech devices to common concepts in life (such as perspective and navigation) can instantly bring people closer and eliminate the sense of mystery.

2. Emphasize the benefits to patients (empathy and comfort) :

Combining the pain point: “Your blood vessels instrument are relatively thin and deep. Let’s take a look at this. It can save you one injection and succeed in one attempt.” This sentence directly hits the patient’s most core fear.

Expressing concern: “This instrument can help us find the best blood vessels and make your process a bit easier.”

3. Real-time communication during the operation process (involve them) :

Invitation to Watch: After scanning a clear blood vessel, turn the screen towards the patient: “Look, this is your blood vessel, displayed very clearly.” We’ll go in from here later.”

Visual explanation: Pointing at the screen, he said, “Look, this one is thicker and straighter. The one beside it is thinner and has forks. We won’t choose it.” Doing so makes patients feel that everything is under control and a clear plan, rather than being operated blindly.

Give a sense of control: Before wiping the coupling agent, you can say: “This gel is a bit cold. Just a reminder for you.” Let the patient have an expectation for the next step.



2) Operational Behavior: Build trust with professionalism and thoughtfulness

Your behavior conveys a sense of security more than your words.

1. Stay confident and composed

You yourself should demonstrate your proficiency and confidence in the equipment. Your composure will directly influence the patients. Even if you are a beginner, you should practice in advance to ensure that the operation process is smooth.

2. Pay attention to patient comfort

Position: Help patients adjust to the most comfortable posture to ensure that they do not become more tense due to an uncomfortable position during the operation.

Keep warm: If the environment is cold, make sure to cover the patient. Coldness can cause blood vessels to constrict and increase tension.

Preheating the coupling agent: If conditions permit, preheat the coupling agent in the palm of your hand before use to avoid the cold touch startling the patient.

3. Gentle and precise operation

Gentle pressing: When the probe touches the skin, be sure to do it gently to avoid forceful pressing that may cause discomfort and pressure to the patient.

Reduce unnecessary scans: Scan with a purpose. Do not aimlessly swing the probe back and forth on the patient’s arm, as this will increase their unease.



3）Scenario-based Response Strategies

The strategy can be fine-tuned for different types of patients:

1. For children:

Gamification: It is called “The mini-game of finding blood vessels” or “Blood Vessel Monster Detector”.

Distract him: Have him look at the images on the screen or chat with him and ask what he sees.

Encouragement and Rewards: Provide positive encouragement and praise throughout the process.

2. For patients who are extremely anxious or have experienced failure before:

Take the initiative to admit and guarantee: “I understand you might be a little worried. It might not have gone smoothly last time.” This time we’ve used this “good helper”, and the situation will be different. Let’s get it done together.

Give the option (if possible) : “Do you think we are looking at the left hand or the right hand?” Even a small choice can increase a patient’s sense of control.

Key Point One: Imaging technology and clarity

This is the core indicator, which directly determines the practical effect of the equipment.

Core technologies: Currently, there are mainly two mainstream technologies, namely infrared imaging and ultrasonic imaging. Infrared light equipment is non-contact and forms images based on the differences in the absorption of near-infrared light by hemoglobin in blood vessels. Ultrasound, on the other hand, directly observes the structure of blood vessels and blood flow through sound waves.

Image quality: Focus on the resolution, contrast and depth of the imaging. High-quality imaging devices can present clear vascular images that contrast sharply with the surrounding tissues on patients of different skin colors and body weights. Especially for deep and tiny blood vessels, whether they can be clearly displayed is the key.

Real-time performance: The image should have no delay and be able to follow the movement of the probe in real time, which is crucial for the dynamic puncture process.



Key Point Two: Patient adaptability and safety

The equipment must be capable of serving a wide range of patient groups and be absolutely safe.

Skin color adaptability: Excellent equipment should have the ability to overcome “skin color bias”, effectively imaging both fair and dark skin. Find out if the device has special calibrations or modes for different skin tones.

Body type adaptability: For patients with obesity, edema or emaciation, whether the penetration ability and imaging effect of the equipment are stable.

Safety level: Confirm that the light source energy of the equipment is within the absolutely safe range of non-ionizing radiation and has obtained the relevant medical device registration certification.



Point Three: Ease of use and workflow integration

The equipment needs to be integrated into the existing clinical process rather than adding to the burden.

Ease of operation: Can the device be used immediately upon startup? Is the calibration process complicated? Is the interface intuitive? Ideally, nurses or doctors should be able to get started after a brief training.

Portability and Design: Is the device Handheld Vein Finder or desktop Vein Finder ? How is the battery life? Whether it is lightweight and ergonomically designed, making it convenient to move and use between wards, emergency rooms and operating rooms.

Sterility and disinfection: Are the parts that come into contact with patients easy to clean and disinfect? Are disposable sterile protective covers provided? This is directly related to infection control.



Key Point Four: Functionality and Augmented Reality Experience

Advanced functions can significantly enhance clinical value.

AR augmented reality projection: Many modern venous imaging devices can directly project vascular images onto the patient’s skin, achieving “what you see is what you get”, allowing the operator not to switch their line of sight back and forth between the screen and the skin, greatly improving the success rate of puncture and the user experience.

Vascular recognition mode: Is there a special mode, such as only showing arteries or veins (by identifying the direction of blood flow), which is very important for certain special treatments?

The International Day of the Blind on October 15th every year is a day that calls for attention to eye health and conveys the hope of light. When we focus on the living predicaments of the visually impaired group, a set of data should prompt more deep thought…

The silent threat of blindness: The insidious nature of retinal diseases

Retinal diseases such as diabetic retinopathy (DR) and age-related macular degeneration (AMD) have become the leading causes of irreversible blindness in China, and most patients have missed the best intervention opportunity by the time they show obvious symptoms. According to statistics, over 250 million people worldwide suffer from vision impairment, and nearly half of them can avoid it through early intervention. However, the limitations of traditional examination methods have caused many patients to miss the best treatment opportunity. In this race against darkness, ZD Medical  precise diagnosis and treatment solutions centered on optical coherence tomography (OCT) scanners are becoming a key force in preventing blindness.
