The Company's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2007 cannot be filed within the prescribed time period because the Company requires additional time for compilation and review to insure adequate disclosure of certain information required to be included in the Form 10-Q.

Horne, Chief Executive Officer, (951) 587-6201 (2) Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If the answer is no, identify report(s) [X] Yes [ ] No (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? [X] Yes [ ] No If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reason why a reasonable estimate of the results cannot be made. Patient Safety Technologies, Inc. (the "Company") anticipates that its revenue for the three months ended March 31, 2007 is significantly greater than its revenue for the three months ended March 31, 2006. The increase in revenue is primarily the result of an increase in sales of the Company's Safety-SpongeTM System during the 2007 period. The Company anticipates that its operating expenses and net loss for the three months ended March 31, 2007 are significantly less than the expenses and net loss for the three months ended March 31, 2006. The decrease in operating expenses for the three months ended March 31, 2007 when compared to March 31, 2006, was primarily the result of stock based compensation expenses, professional fees, and to a lesser extent salaries and employee benefits. Net loss decreased for the three months ended March 31, 2007 compared to the three months ended March 31, 2006 primarily as a result of a significant decrease in operating expenses. A reasonable estimate of the results cannot be made at this time due to the fact that the compilation, dissemination and review of the information required to be presented in the Form 10-Q has not been completed. 3 Patient Safety Technologies, Inc. -------------------------------------------- (Name of Registrant as specified in Charter) has caused this notification to be signed on its behalf by the undersigned thereunto duly authorized.
