GREASE GUN SPRAY GUN A HIGH PRESSURE INJECTION HAND INJURY MAY LOOK DECEIVINGLY NOT THAT BAD DONT BE FOOLED SEE A DOCTOR IMMEDIATELY

---

What are the three most common devices responsible for high pressure injection hand injuries? I'm sure the answer is on the tip of your tongue. A person with a high pressure hand injury often delays going to the doctor because the hand injury may seem deceptively not that bad. Not a smart move. With a high pressure hand injury immediate medical attention is crucial. "Typically the patient presents with an asymptomatic benign-appearing puncture wound at the injection site and may delay seeking treatment."

Which of these are the top three devices responsible for high pressure injection hand injuries?

"Most high-pressure injection hand injuries are industry-related and the preponderance are from grease guns, spray guns, and diesel injectors". Other guns that reportedly cause such hand injuries include paint guns, concrete guns, and plastic injectors. Grease is the material injected most often, followed by paint. Water, wax, paint thinner, cement, plastic, oil, and hydraulic fluid have also been reported".




Injection pressures generally are 2,000-10,000 psi. As RLBates points out at Suture for a Living, "Thankfully, high-pressure injection injuries to the hand are uncommon because they have the potential to cause devastating consequences. To complicate things, these hand injuries often look innocuous with their initial presentation. Despite this innocuous looking injury, these accidents should be treated as limb-threatening injuries and immediately referred to a hand surgeon.

The three most common devices responsible for these hand injuries are:

1) grease guns -- A force of 100 to 200 psi (pounds per square inch) is generated by air compressors to propel the grease through the lubricating mechanism. The actual force is amplified by a pump and a reducing nozzle, so that a pressure of 5000 to 10,000 psi is generated.

2) spray guns -- A hydraulic pump forces paint through the spray gun at pressures up to 5000 psi.

3) diesel fuel injectors -- Pressures from 2000 to 6000 psi
