Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the mounting piece 1, the flexible bump 2, the limiting clamping groove 21, the fixing piece 3, the hair surface 31, the hook surface 32, the pressing sheet 4, the anti-slip strip 5 and the limiting sleeve 6.
Example 1:
a fixing structure of an exposed joint of a central venous catheter is basically shown as figure 1 and comprises a fixing sleeve and a pressing sheet 4, wherein the fixing sleeve is in a ring shape and is in an integrally formed net shape, or the fixing sleeve comprises a mounting sheet 1 and a plurality of connecting pieces. In this embodiment, the latter is preferably selected for the structure of the fixing sleeve, that is, the fixing sleeve includes the mounting plate 1 and a plurality of connecting members, the number of the connecting members is an even number, in this embodiment, the number of the connecting members is 6, and the 6 connecting members are respectively fixed on the left and right sides of the mounting plate 1; and the connecting piece of installation piece 1 both sides is 3, and 3 connecting pieces of every side are fixed respectively at the upside, middle part and the downside of installation piece 1.
The connecting piece is for connecting rope or stationary blade 3, and stationary blade 3 is chooseed for use to the connecting piece in this embodiment, stationary blade 3 and 1 integrated into one piece of installation piece, and all is provided with the magic subsides on the stationary blade 3, and the magic is pasted and is included matte surface 31 and collude face 32, and matte surface 31 fixes on left stationary blade 3, combines that fig. 2 is shown, colludes face 32 and fixes the back at the stationary blade 3 on right side in fig. 1, and this side stationary blade 3 is located fig. 2's left side.
Installation piece 1 is netted, and the middle part of installation piece 1 is fixed with flexible lug 2, and flexible lug 2 is silica gel lug or latex lug, and in this embodiment, flexible lug 2 chooses for use the latex lug. The upper surface of the flexible lug 2 is provided with a vertical limiting clamping groove 21, the width of the limiting clamping groove 21 is smaller than that of the maximum size of the exposed joint, and the exposed joint can be fixed in the limiting clamping groove 21.
Compress tightly thin slice 4 and cover on flexible lug 2, and the left side and the right side that compress tightly thin slice 4 all are fixed with installation piece 1, compress tightly the left part and the right part on the side of thin slice 4 all fixed with installation piece 1 for compress tightly and form a through-hole between the middle part of thin slice 4 downside and the flexible lug 2, the size of through-hole is less than the size that exposes the joint. A placing space with both upper and lower ends communicated is formed between the pressing sheet 4 and the flexible lug 2.
With reference to fig. 2, four anti-slip strips 5 are fixed on the back of the mounting plate 1, the four anti-slip strips 5 are respectively fixed at the side edges of the mounting plate 1, and the anti-slip strips 5 are respectively flush with the side edges of the mounting plate 1. The side of the anti-skid strip 5 far away from the mounting piece 1 is integrally formed with corrugated bulges. Antislip strip 5 and arch are silica gel or latex material, select for use silica gel in this embodiment.
The specific implementation process is as follows:
after a patient is placed in a central venous catheter (PICC) through a peripheral vein, a part of the catheter is placed outside the body, and an exposed joint is arranged on the catheter placed outside the body, so that subsequent transfusion is facilitated. At the moment, the exposed joint and the catheter need to be fixed, so that the situation that the exposed joint falls off or the patient feels pain due to the fact that the patient pulls the exposed joint and the catheter in the normal moving process is avoided.
When the exposed joint is fixed, the exposed joint penetrates through the through hole, so that the exposed joint is positioned in a placing space formed between the pressing sheet 4 and the mounting sheet 1, and is clamped into the limiting clamping groove 21 on the flexible bump 2, and the exposed joint is fixed and limited. And then fixing the external catheter by using the adhesive tape. The fixed position of the exposed joint on the arm of the patient is determined, the back face of the installation piece 1 is tightly attached to the arm of the patient, the magic tapes on the fixing pieces 3 on the two sides are adhered to fix the exposed joint, and the position of the magic tape adhesion can be adjusted according to the size of the arm of the patient in the process.
After the exposed joint is fixed, the anti-slip strip 5 is arranged on the back surface of the mounting piece 1, so that the probability of sliding of the mounting piece 1 can be reduced, and the fixing effect of the exposed joint is improved. And even if the exposed joint is subjected to external force, the probability of falling off of the exposed joint can be reduced due to the double limiting action of the compression sheet 4 and the flexible lug 2 on the exposed joint.
Example 2:
The specific implementation process is as follows:
after a patient puts a central venous catheter (PICC) through a peripheral vein, the catheter and the exposed joint of the external part penetrate through the middle part of the bottom of the limiting sleeve and penetrate out of the opening, and then penetrate through the through hole to form a placing space between the compression sheet and the installation sheet, and the exposed joint is fixed in the placing space.
Then the limiting sleeve 6 is sleeved on the arm of the patient, the limiting sleeve is rolled up towards the direction close to the mounting sheet 1, the exposed catheter is fixed by the adhesive tape and then put down and curled, so that the limiting sleeve 6 covers the exposed catheter, and the limiting and the protection of the exposed catheter are realized. The fixing piece 3 is used to fix the mounting piece 1.
For those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the patent and the practicability of the patent.
