JCMED's medical consumables are widely used in clinical diagnosis, treatment and patient care, helping medical staff to better manage patients' health conditions.
Electrosurgical pen is used to cut, coagulate and cauterize tissues. The heat generated by high-frequency current can achieve precise tissue separation and hemostasis, reduce the amount of bleeding during surgery, and improve the efficiency and safety of surgery.
Electrode sheets, various types of electrode wires and blood oxygen temperature probes are used in conjunction with various medical monitoring equipment or electrotherapy equipment, such as electrocardiographs, monitors, etc., to ensure the stable transmission of electrical signals, so that the equipment can accurately collect and display the electrophysiological information of the human body.
Coupling agent is used for ultrasound examination and is applied to the skin to improve the contact between the ultrasound probe and the skin and reduce air interference.
Feeding bags, nasogastric tubes, gastric catheters and nutritional catheters are used together to provide enteral nutrition for patients who cannot eat orally or need special nutritional support.
Suture needles and sutures are used in surgical operations to suture wounds, bring tissues together and promote wound healing.
Patches are often used in hernia repair surgery, abdominal wall reconstruction surgery, etc. By placing the patch in the defect or weak part of the abdominal wall, the strength of the abdominal wall is strengthened, the protrusion of abdominal contents is prevented, and tissue repair and healing are promoted.
Although both are cables for bioelectric signal acquisition, they have significant differences in design, function and application scenarios, and are usually not universal.
The reasons are as follows:
1. Different number of electrodes: EEG cables usually require more electrodes, while ECG/EKG cables have fewer electrodes.
2. Different signal types: EEG signals and ECG signals have different frequency ranges and characteristics, and the equipment processes them differently.
3. Different interfaces and protocols: The interfaces and signal transmission protocols of EEG devices and ECG/EKG devices may be incompatible.
Clean the stains on the cable surface in time after use, avoid pulling or twisting the cable, and store it neatly to avoid excessive bending. Check the cable interface regularly to see if it is loose or damaged. If there is any problem, repair or replace it in time.
The electrode wire should be arranged to avoid excessive bending, winding or stretching. It should be stored in a dry and ventilated environment and avoid being placed together with sharp objects to prevent scratching the outer skin.
In general, medical coupling agents are safe and non-irritating to the skin. However, for a small number of patients with sensitive skin, slight redness, itching and other discomfort symptoms may occur. If this happens, it should be cleaned with clean water in time and the doctor should be informed.
The retention time of nasogastric tubes and gastric catheters varies depending on the material of the catheter and the patient's condition. Generally, ordinary nasogastric tubes can be left in place for 7-10 days, and silicone nasogastric tubes can be left in place for about 1 month. If the gastric catheter is a percutaneous gastrostomy tube, it can be left in place for several months or even longer depending on the situation, but it needs to be replaced regularly to prevent infection and catheter aging.
Choose according to factors such as the surgical site, tissue type, and wound size. For example, triangular needles are generally used for skin sutures, and round needles are commonly used for gastrointestinal tract sutures; the thickness of the suture thread should match the suture needle, and the healing time and tension of the tissue should be considered. Absorbable suture threads are suitable for some parts that do not require long-term retention of suture threads, and non-absorbable suture threads are used in situations where long-term tissue fixation is required.
