Description

Technical Field

[0001] The present invention relates to the technical field of vein positioning, and in particular to a positioning device for vein treatment. Background Art

[0002] During sclerotherapy and puncture of varicose veins, the vein locator can help medical staff find the target vein quickly and accurately, thereby improving the success rate of treatment. During the use of the vein locator, the nurse needs to hold the vein locator perpendicular to the treatment position and keep the distance within 15 cm.

[0003] For example, CN112972834B discloses a positioning auxiliary device for peripheral arteriovenous puncture and catheterization; the positioning auxiliary device for peripheral arteriovenous puncture and catheterization comprises: a base plate and a support; a positioning structure, and the positioning structure is arranged on one side of the support. The present invention provides a positioning auxiliary device for peripheral arteriovenous puncture and catheterization, which can be used in conjunction with the puncture and catheterization by setting a positioning structure, and can be used as an auxiliary positioning structure for the puncture and catheterization to provide assistance to trainee medical staff. When puncturing the patient's artery, the puncture and catheterization can be effectively positioned. The trainee medical staff only needs to push the puncture and catheterization to move, and does not need to hold the puncture and catheterization all the time, thereby greatly reducing the direct contact area between the hand and the puncture and catheterization. Even if the hand shakes or slips due to nervousness, the impact on the puncture and catheterization can be minimized, so that the puncture and catheterization can always move in a relatively stable state, thereby greatly improving the success rate of puncture.

[0004] However, when treating multiple veins of a patient, the position of the vein locator needs to be changed frequently. If the vein locator is accidentally dropped or hit during the transfer process, it is easy to cause the outer shell of the vein locator to be damaged, the internal components to be loose or damaged, etc., which can easily lead to inaccurate detected vein position, increasing the difficulty and risk of venipuncture. The vein locator needs to be replaced in time. Replacing the vein locator takes a certain amount of time, which not only affects the continuity of medical work, but also easily causes delays to the patient's treatment and affects the treatment efficiency.

[0005] In view of this, the present invention provides a positioning device for intravenous treatment, which ensures the stability of the vein detection head during use, effectively avoids the shaking of the detection head due to fatigue when holding the vein locator for a long time, ensures the convenience of use of the vein locator, and is also convenient for replacing the damaged vein detection head, avoids the collision of the vein detection head during the transfer of the vein locator, avoids damage to the vein locator, ensures the accuracy of the vein detection position, reduces the difficulty and risk of venous puncture, increases the service life of the vein locator, reduces the replacement frequency of the vein locator, saves a lot of time, ensures the continuity of medical work, avoids delays in the treatment of patients, improves treatment efficiency, reduces the shaking of the patient's treatment site during the treatment process, ensures the treatment effect, and also avoids repeated adjustment of the patient's treatment site, reduces the labor burden of medical staff, can buffer the squeezing force on the patient's skin, avoids mechanical damage to the patient's skin due to excessive pressure, and ensures the safety of the use of the vein locator.
