Detailed Description

The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of the invention, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit the scope of the invention.

The technical solution of the present invention is described below with reference to fig. 1 to 8 by specific embodiments:

as shown in figure 1, the utility model is used for carrying out physical isolation protection on an ultrasonic probe 1 of a transesophageal echocardiogram. Wherein, the ultrasonic probe 1 comprises a probe body 11, a flexible shaft part 12 and an elastic shaft part 13; the flexible shaft portion 13 is connected to the distal probe manipulation device. Wherein, the probe body 11 is a similar rectangular body, and a probe wafer is embedded on one side surface of the probe body; the probe wafer can work normally only by being soaked with the ultrasonic couplant. The flexible shaft part 12 is a flexible shaft and is connected with the probe body 11 through a first connecting part A. The cross-sectional area of the first connection portion a is larger than the cross-sectional area of the flexible shaft portion 12. The flexible shaft portion 12 is connected to the flexible shaft portion 13 by a second connection portion B having a cross-sectional area larger than the cross-sectional areas of the flexible shaft portion 12 and the flexible shaft portion 13.

As shown in fig. 2, the ultrasonic probe protective sleeve device of the present invention is used for physically isolating and protecting a probe body 11 with a probe wafer 111, a flexible shaft portion 12 and an elastic shaft portion 13 close to the flexible shaft portion 12 in an ultrasonic probe 1; comprises an inner sleeve 31, an outer sleeve 32 and a fixing component 33; and may also include a sleeve clearance for securing the second sleeve end of the outer sleeve 32 to the inner sleeve 31. The outer sleeve closing portion may be any type of fixing member having a function of fixing the outer fixing sleeve 32 to the inner sleeve 31.

Alternatively, the sleeve closing-in part is a closing-in fixing part 2 with a binding band structure as shown in fig. 5, and the material is preferably medical rubber material with elasticity.

Alternatively, the sleeve receptacle may be a snap fastener assembly disposed directly on itself at the second sleeve end of the fixed sleeve 32.

Preferably, as shown in fig. 4, the sleeve cuff is a cuff band 321 of the same material that is heat-fused to the fixed sleeve 32 near the second sleeve end port. The closing-in band 321 can function as a binding band when it is necessary to bind the second sheath end of the sheath 32 to the inner sheath 31, and can be used as a drag assisting body to be wound around a finger when a doctor operates the ultrasonic probe of transesophageal echocardiogram with his hand, and the auxiliary sheath 32 slides on the inner sheath 31. Further preferably, the length of the closing-in band 321 is greater than that of the outer sleeve 32, so that the outer sleeve 32 can cover the exposed outer part of the inner sleeve all the time before and after use, thereby protecting the inner sleeve from environmental pollution.

The inner sleeve 31 has elasticity, is preferably made of medical rubber, is shaped like a rubber finger sleeve for medical finger examination, and structurally comprises an inner sleeve blind end part 311, an inner sleeve tightening part 312 and an inner sleeve opening part 313 which are connected in sequence; specifically, one end of the inner sleeve 31 is a blind inner sleeve end 311, and the other end is an inner sleeve opening.

The inner sleeve 31 is not a sleeve body of equal radius in the design sense. The cross sectional area of each part is different in size, and the cross sectional area relationship is as follows: inner sleeve tightening part 312< inner sleeve blind end part 311< inner sleeve opening part 313. The inner sleeve blind end 311 is used for injecting an ultrasonic couplant so that the probe wafer is in a working environment.

At the beginning of use, the ultrasound coupling agent is first injected into the inner sleeve blind end portion 311. The length of the inner sleeve blind end part 311 is slightly larger than that of the probe body 11 arranged on the ultrasonic probe 1; the designed cross-sectional area is smaller than that of the probe body 11, so that the ultrasonic probe 1 is tightly sleeved in the inner sleeve blind end part 311, and the probe wafer 111 on the probe body 11 can be soaked with the ultrasonic couplant, thereby ensuring the definition of an ultrasonic image.

The inner sleeve constricted part 312 is located behind the first connection part a of the probe body 11, and has a smaller cross-sectional area than the inner diameter blind end part 311 and the inner sleeve opening part 313. Because the inner sleeve 31 has elasticity, when the probe body 11 is sleeved into the inner diameter blind end portion 311, the probe body 11 needs to be forced to pass through the inner sleeve tightening portion 312 and be inserted into the inner diameter blind end portion 311, so that the inner sleeve 31 has a function of self-locking by elastic force on the soft shaft portion 12 behind the first connecting portion a of the probe body 11, and the ultrasonic couplant is ensured to overflow from the inner diameter blind end portion 311 as little as possible in the process of being inserted into the esophagus, so as to ensure that the probe wafer 111 is always immersed in the ultrasonic couplant.

The designed cross-sectional area of the inner sleeve opening 313 is in clearance fit with the flexible shaft part 12 and the elastic shaft part 13 of the ultrasonic probe 1, so that the inner sleeve 31 is not wound and fixed on the ultrasonic probe 1 in a long sleeving stroke.

Preferably, the inner sleeve opening 313 has a horn shape from the connection with the inner sleeve tightening part 312, so that the inner sleeve 31 can be conveniently sleeved on the ultrasonic probe 1; the outer surface of the initial section of the opening 313 of the inner sleeve is provided with scales, as shown in fig. 3, which can help the examiner to know the depth of the ultrasonic probe 1 extending into the esophagus of the patient. Wherein the starting calibration of the scale takes into account the length of the inner diameter blind end portion 311 and the inner sleeve tightening portion 312. Specifically, the sum of the design lengths of the inner diameter blind end portion 311 and the inner sleeve tightening portion 312 in this embodiment is 15cm, and therefore, the initial calibration value is set to 15. As shown in fig. 3.

Considering that the insertion depth of the ultrasonic probe during the inspection is 35-50cm and the coverage of the inspection hand, it is preferable that the length of the inner sleeve 31 is more than 70cm in order to cover the protection range of the inner sleeve to the range held by the inspector of the elastic shaft portion of the ultrasonic probe 1.

The coat 32 is a sleeve body made of thin-wall flexible material and with two open ends, and is preferably medical transparent thin plastic; the two ends are respectively a first outer sleeve end and a second outer sleeve end. Setting the cross section area of the outer sleeve 32 to be larger than that of the inner sleeve opening part 313, so that the outer sleeve 32 is loosely sleeved outside the inner sleeve 31; the first outer sleeve end of the outer sleeve 32 and the inner sleeve opening of the inner sleeve 31 are fastened to the elastic shaft portion 13 of the ultrasonic probe 1 by a fastening member 33.

The outer sleeve 32 has a greater overall length than the inner sleeve 31, as shown in fig. 8, in order to keep the position of the hand of the doctor when the ultrasonic probe 1 is initially inserted into the mouth of the patient on the outer sleeve 32, and to avoid contamination of the inner sleeve 31 and thus the patient with the insertion of the ultrasonic probe 1. With the insertion of the ultrasonic probe 1, since the cross-sectional area of the outer sheath 32 is larger than that of the inner sheath 31, the doctor can control the outer sheath 32 to recede on the inner sheath 31 toward the inner sheath opening 313 as the examination hand is withdrawn. When the ultrasonic probe is partially withdrawn in the examination, the second outer sleeve end of the outer sleeve 32 can be dragged to the position near the mouth of the patient, the second outer sleeve end of the outer sleeve 32 is fixed on the ultrasonic probe 1 with the inner sleeve 31 outside the mouth of the patient through the outer sleeve closing part arranged at the second outer sleeve end, the pollution of the environment to the inner sleeve 31 in the operation process is avoided, and the pollution of the environment of the ultrasonic probe 1 which is repeatedly plugged and pulled out to the patient in the operation process is also avoided. The outer cover 32 is a medical transparent thin plastic product.

Preferably, the cross-sectional area of the inner sleeve blind end portion 311 is smaller than the cross-sectional area of the inner sleeve opening portion 313 and larger than the cross-sectional area of the inner sleeve tightening portion 312.

The fixing member 33 fixes the first outer sleeve end of the outer sleeve 32 and the inner sleeve opening portion 313 of the inner sleeve 31 to the elastic shaft portion 13 in alignment. In order to prevent the inner sleeve 31 from being possibly sucked under the influence of the negative pressure in the patient body in the process of withdrawing the ultrasonic probe 1, the inner sleeve opening part 313 of the inner sleeve 31 is optionally made into an outward flanging structure, as shown in fig. 3; the turnover structure is convenient for clamping on one hand, and on the other hand, the inner sleeve 31 is not easy to slip off from the fixed component 33. The first sleeve end of the sleeve 32 may also be configured to be everted over as shown in fig. 4.

The fixing assembly 33 comprises a first fixing half 331, a second fixing half 332 and a locking member 333, as shown in fig. 6.

Preferably, the first and second fixing half bodies 331 and 332 are rubber bodies having hardness and elastic deformation, are snap rings each having a small semicircle, and are provided with fixing lug portions. The ear plates are provided with through holes and are elastically fastened together through fasteners.

Preferably, the ear plate of the second fixed half 332 is provided with a through slot outwards; the locking member 333 includes a screw 3331 and a nut 3332. The screw 3331 is fused on the first fixed half body 331, and the nut 3332 is movably limited on the screw 3331 to form a connected piece, so that the nut 3332 is screwed on the screw 3331. In use, the second fixed half 332 is axially butted against the first fixed half 331 through the through slot, and the nut 3332 is rotated to tightly couple the first fixed half 331 and the second fixed half 332. When not in use, the fixing components 33 can be butted into a whole for storage.
