Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic probe fixation, and particularly relates to a sterile fixation device for an ultrasonic probe dedicated to blood vessel puncture. Background Art

[0002] When performing blood vessel puncture on a patient's upper limb, medical staff need to hold an ultrasonic probe and place it on the patient's upper limb blood vessel to guide the blood vessel puncture. Since the probe is coated with coupling agent, it is very easy to slide, which requires a high level of stability of the medical staff's hands and is not conducive to beginners. Once the ultrasonic probe slides and the midpoint shifts, the puncture needle will not be above the blood vessel but on the side of the blood vessel after piercing the skin, and the puncture fails and needs to be repeated. Repeated punctures cause the puncture needle to move multiple times in the subcutaneous tissue, which is likely to cause skin damage and increase the risk of infection and bleeding at the puncture site of the patient. In addition, the existing ultrasonic puncture head must be covered with a sterile protective cover before puncture, and the operation is very cumbersome, increasing the operation time. Therefore, the present invention provides a sterile fixation device for an ultrasonic probe dedicated to blood vessel puncture. Summary of the Invention

[0003] The purpose of the present invention is to provide a sterile fixation device for an ultrasonic probe dedicated to blood vessel puncture.

[0004] To solve the above technical problems, the purpose of the present invention is achieved as follows:

[0005] A sterile fixation device for an ultrasonic probe dedicated to blood vessel puncture, comprising: a fixed base; an opening adapted to the ultrasonic probe is provided at the center of the fixed base;

[0006] Two upper limb clamping blocks, the upper limb clamping blocks are slidably arranged below the fixed base along the transverse direction of the fixed base and are located on both sides of the opening, and the top ends extend into the inside of the fixed base and are connected to a first spring arranged inside the fixed base; the first spring makes the upper limb clamping blocks have a clamping force towards the center of the fixed base;

[0007] Two probe clamping plates, the probe clamping plates are slidably arranged relative to each other along the longitudinal direction of the fixed base in the opening, the top extends above the fixed base, and both ends extend into the inside of the fixed base and are connected to a second spring arranged inside the fixed base; the second spring makes the probe clamping plates have a clamping force towards the center of the fixed base;

[0008] A sterile transparent film; the sterile transparent film is connected to the bottom of the opening and can be stretched.

[0009] On the basis of the above solution and as a preferred solution of the above solution, the fixed base has a rectangular column structure; the opening is a rectangular hole.

[0010] On the basis of the above solution and as a preferred solution of the above solution, the upper limb clamping block includes an arc-shaped clamping part, a sliding block and a connecting block; the arc-shaped clamping part is located below the fixed base; the number of the sliding blocks is two, symmetrically arranged on the top of the arc-shaped clamping part, and slidably matched in the first sliding groove opened at the bottom of the fixed base; the connecting block is arranged between the two sliding blocks, and both ends are respectively connected to the two sliding blocks, and is slidably matched in the second sliding groove opened inside the fixed base; the first side surface of the connecting block is connected to the first spring arranged in the second sliding groove.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] As Figure 1 and Figure 2 shown, a sterile fixing device for a vascular puncture special ultrasonic probe includes: a fixed base 1, two upper limb clamping blocks 3, two probe clamping plates 5 and a sterile transparent film 7.

[0025] An opening 2 adapted to the ultrasonic probe is provided at the center of the fixed base 1. Preferably, the fixed base 1 has a rectangular column structure. The fixed base 1 with a regular columnar structure is convenient for matching with the upper limb of the patient. The opening 2 is a rectangular hole and is adapted to the ultrasonic probe. At the same time, the length of the opening 2 is greater than or equal to the length of the ultrasonic probe, so that the ultrasonic probe can be horizontally moved in the opening 2 to realize position adjustment.

[0026] As Figure 3 shown, the upper limb clamping blocks 3 are slidably arranged below the fixed base 1 along the transverse direction of the fixed base 1 and are located on both sides of the opening 2. The top ends of the upper limb clamping blocks 3 extend into the inside of the fixed base 1 and are connected to the first spring 4 arranged inside the fixed base 1. The first spring 4 makes the upper limb clamping blocks 3 have a clamping force towards the center direction of the fixed base 1. When the device is in the initial state, the two upper limb clamping blocks 3 are relatively close to the middle of the fixed base 1. When the patient's upper limb is clamped, the two upper limb clamping blocks 3 move away from each other and compress the first spring 4.

[0027] Preferably, in this embodiment, the upper limb clamping block 3 includes an arc-shaped clamping part 31, a sliding block 32 and a connecting block 33. The arc-shaped clamping part 31 is located below the fixed base 1 and is used for matching with the upper limb of the patient. The number of the sliding blocks 32 is two, which are symmetrically arranged on the top of the arc-shaped clamping part 31 and are slidably matched in the first sliding groove opened at the bottom of the fixed base 1. The sliding blocks 32 are arranged near both sides of the top of the arc-shaped clamping part 31. The connecting block 33 is arranged between the two sliding blocks 32, and both ends are respectively connected to the two sliding blocks 32 and are slidably matched in the second sliding groove opened inside the fixed base 1. There is a gap between the connecting block 33 and the top surface of the arc-shaped clamping part 31, so that the upper limb clamping block 3 cannot be separated from the fixed base 1.

[0028] The first side of the connecting block 33 is connected to the first spring 4 disposed in the second sliding groove. The number of the first springs 4 is several, and they are evenly distributed along the length direction of the connecting block 33 and are in a compressed state, so that the upper limb clamping block 3 is kept close to the center of the fixed base 1.

[0029] As Figure 4 shown, the probe clamping plate 5 is slidably disposed in the opening 2 longitudinally relative to the fixed base 1, with its top extending above the fixed base 1, and both ends extending into the fixed base 1 and connected to the second spring 6 disposed in the fixed base 1. The second spring 6 applies a clamping force to the probe clamping plate 5 in the direction of the center of the fixed base 1 to clamp the ultrasonic probe located between the two probe clamping plates 5. The probe clamping plate 5 is perpendicular to the fixed base 1 to keep the ultrasonic probe perpendicular to the fixed base 1 when it is fixed.

[0030] Preferably, the probe clamping plate 5 includes a probe clamping plate body 51 and an insertion portion 52. The probe clamping plate body 51 is disposed in the opening 2 and serves as a clamping member for clamping the ultrasonic probe, and its side surface is adapted to the outer shape structure of the ultrasonic probe. The number of the insertion portions 52 is two, which are respectively disposed at both ends of the probe clamping plate body 51 and are located at the bottom of the probe clamping plate body 51. The insertion portions 52 are inserted into the third sliding grooves opened on the fixed base 1, and their first sides are connected to the second spring 6 disposed in the third sliding grooves. The third sliding grooves are above the second sliding grooves. The number of the second springs 6 is several, and they are evenly distributed along the length direction of the insertion portion 52, and the second spring 6 is located between the two probe clamping plates 5. When the device is in the initial state, the second spring 6 is in the initial state, and when the probe clamping plate 5 clamps the ultrasonic probe, the second spring 6 is stretched.

[0031] The probe clamping plate 5 has a transparent structure and is made of a transparent material, which is convenient for observing the midline position of the ultrasonic probe clamped between the two probe clamping plates 5 for corresponding puncture.

[0032] In addition, a window is opened on the fixed base 1 corresponding to the opening 2 to facilitate observing the position of the ultrasonic probe in the opening 2.

[0033] The sterile transparent film 7 is connected to the bottom of the opening 2 and can be stretched to prevent the ultrasonic probe from directly contacting the skin, improving safety and hygiene.

[0034] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
