Description

Technical Field

[0001] The utility model relates to the technical field of endoscopes, in particular to an airbag type membrane sleeve ruler. Background Art

[0002] With the rapid development of science and technology, the application field of endoscopes is becoming more and more extensive. It can not only be used for the diagnosis of diseases, but more importantly, for minimally invasive treatment of diseases. Measuring the actual size of lesions under direct endoscope vision is of great significance for the diagnosis of diseases and comparative analysis before and after treatment. The size of the lesion seen on the endoscope display will change with the change of the distance between the endoscope lens end and the lesion. The closer the endoscope lens end is to the lesion, the larger the lesion will appear; the farther the endoscope lens end is from the lesion, the smaller the lesion will appear.

[0003] The size of the lesion sometimes directly affects the choice of treatment plan and the judgment of efficacy. Especially in the process of observing the efficacy of clinical treatment, it is very important to pay attention to and accurately record the size of the lesion. At present, the diagnosis of the size of lesions under endoscopy can only be estimated by experience or by using the size of the opening of the biopsy forceps as a reference. For example, the diameter of the endoscope body is used as a reference. Because of the different distances from the lesion, the estimated size of the lesion is inaccurate; for example, the size of the opening of the gastroscopic biopsy forceps is used as a reference. Because its position cannot be completely parallel to the lesion, or the lesion itself is relatively large, the calculated size of the lesion is also inaccurate. Therefore, it is impossible to directly and accurately measure the actual size of the lesion through the existing technology to make a correct treatment plan and judgment of efficacy. Utility Model Content

[0004] In order to solve the technical problem in the prior art that the actual size of the lesion cannot be directly and accurately measured, the utility model provides an airbag membrane sleeve ruler.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: an airbag type membrane sleeve ruler, including a tube body, a latex membrane sleeve and an air inlet pipe. The tube body is a hollow structure, and the latex membrane sleeve is installed at one end of the tube body. The latex membrane sleeve includes a mounting section, a supporting section and a measuring section for measuring the size of the target. One end of the supporting section is connected to the mounting section, and the other end of the supporting section is connected to the measuring section. The surface of the measuring section is printed with scales. The mounting section is provided with a sleeve, and the inner diameter of the sleeve is greater than or equal to the outer diameter of the tube body, so that the mounting section can be sleeved on the outside of the tube body through the sleeve; the air inlet pipe is installed on the other end of the tube body away from the latex membrane sleeve, and the air inlet pipe is provided with an air inlet port 1, and the air inlet port 1 is connected to the latex membrane sleeve through the tube body; the gas of the tube body is extracted through the air inlet port 1, and the measuring section and the supporting section are both received in the tube body; the gas is transported to the tube body through the air inlet port 1, and the measuring section and the supporting section extend out of the tube body under air pressure, so that the measuring section and the supporting section form a T-shaped scale for measuring the size of the target.

[0006] As a further improvement of the above solution, the airbag membrane sleeve scale also includes an air intake device for conveying gas to the latex membrane sleeve through the air intake pipe, and the air intake device is detachably connected to the air intake pipe.

[0007] As a further improvement of the above scheme, the measuring section includes a measuring section one and a measuring section two, and the measuring section one and the measuring section two are symmetrically arranged on both sides of the supporting section. When gas is introduced into the air inlet one, the measuring section one and the measuring section two can extend out of the tube body and be arranged vertically with the tube body.

[0008] As a further improvement of the above solution, the installation section and the support section are an integrated structure.

[0009] As a further improvement of the above scheme, the supporting section is provided with an air outlet 1, and the measuring section is provided with an air inlet 2. The air inlet 2 and the air outlet 1 are of the same size, and the end face where the air outlet 1 is located is connected to the end face where the air inlet 2 is located by gluing.

[0010] As a further improvement of the above solution, the air inlet pipe is a Luer connector.

[0011] As a further improvement of the above solution, the air intake device is a syringe, and the syringe is connected to the tube body through the Luer connector.

[0012] As a further improvement of the above solution, the diameter of the tube body is smaller than the diameter of the endoscope channel hole.

[0013] As a further improvement of the above solution, the installation section and the pipe body are connected by gluing.

[0014] Furthermore, the wall thickness of the latex film sleeve is 0.02 mm to 0.06 mm.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In the utility model, the measuring section and the supporting section of the latex membrane sleeve are both retracted into the tube body when not measuring. Therefore, during the measurement process, the measurement can be carried out as long as the tube body can reach the measuring section, and the measurement result is accurate. During the measurement, only a small amount of air is needed to prop it up and unfold it to achieve the measurement. The structure of the entire airbag membrane sleeve scale is simple, and the measurement operation process is simple and convenient. Moreover, since it is a latex membrane sleeve, all surfaces are very smooth, so even if it comes into contact with human tissue during use, it will not cause damage to human tissue.

[0017] (2) The latex membrane sleeve of the utility model occupies a relatively small space when unfolded. Therefore, the airbag membrane sleeve ruler of the utility model can be used to measure some lesions or areas with relatively small wounds, thereby improving its practicality.

[0024] The present invention is further described below in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0026] Reference Figure 1 As shown, an embodiment of the utility model provides an airbag membrane scale, including a tube body 1, a latex membrane sleeve 2 and an air inlet pipe 3. One end of the tube body 1 is connected to the latex membrane sleeve 2, and the other end of the tube body 1 is connected to the air inlet pipe 3. The external gas can be inflated to the latex membrane sleeve 2 through the air inlet pipe 3 and the tube body 1. The latex membrane sleeve 2 can extend out of the tube body 1 and inflate under the action of air pressure to form a T-shaped solid ruler, so that the latex membrane sleeve 2 can be used as a measuring tool to measure targets such as lesions or wounds. The measurement process is simple and convenient, and the measurement results are accurate. In this embodiment, by using an ultra-thin latex membrane sleeve 2, all its surfaces are relatively smooth, and it can be propped up by filling a small amount of air, which can achieve effective measurement of the target size without causing damage to human tissue due to the expansion of the latex membrane sleeve 2.

[0027] Please refer to Figure 4 The tube body 1 is a hollow structure, and the hollow structure facilitates the gas in the air inlet pipe 3 to enter the latex film sleeve 2 through the hollow structure of the tube body 1, so as to unfold the latex film sleeve 2, so that the unfolded latex film sleeve 2 can measure the target size.

[0028] In this embodiment, the tube body 1 can be made of a thin-walled and rigid polymer material, such as medical polyethylene, medical polyurethane, etc.

[0029] The latex film sleeve 2 is installed at one end of the tube body 1. The latex film sleeve 2 includes a mounting section 21, a supporting section 22, and a measuring section 23 for measuring the size of the target. One end of the supporting section 22 is connected to the mounting section 21, and the other end of the supporting section 22 is connected to the measuring section 23. The surface of the measuring section 23 is printed with scales, and the measuring section 23 can measure the size of the target through the printed scales. A sleeve is provided on the side of the mounting section 21 away from the supporting section 22, and the inner diameter of the sleeve is greater than or equal to the outer diameter of the tube body 1, and the mounting section 21 can be sleeved on the outside of the tube body 1 through the sleeve. Thereby achieving the purpose of connecting the mounting section 21 and the tube body 1.

[0030] Please refer to Figures 2 to 4 As shown, the air inlet pipe 3 is installed on the other end of the tube body 1 away from the latex membrane sleeve 2. The air inlet pipe 3 is provided with an air inlet 31, and the air inlet 31 is connected to the latex membrane sleeve 2 through the tube body 1. The gas in the tube body 1 is extracted through the air inlet 31, and the measuring section 23 and the supporting section 22 are both received in the tube body 1. The gas is delivered to the tube body 1 through the air inlet 31, and the measuring section 23 and the supporting section 22 extend out of the tube body 1 under air pressure, so that the measuring section 23 and the supporting section 22 form a T-shaped solid scale for measuring the target size.

[0031] Please refer to Figure 4 and Figure 5 When the gas in the tube body 1 is extracted through the air inlet 31, the air pressure in the tube body 1 is lower than the air pressure outside the tube body 1. Under the action of the air pressure difference, the measuring section 23 and the supporting section 22 are able to shrink into the tube body 1. When the gas is delivered to the tube body 1 through the air inlet 31, the measuring section 23 and the supporting section 22 stored in the tube body 1 are able to extend out of the tube body 1 under the action of the air pressure and expand into a T-shaped structure. Thus, the measuring section 23 can measure the size of the target.

[0032] The airbag membrane sleeve scale may further include an air intake device, which is detachably connected to the air intake pipe 3 , and is used to transport gas to the latex membrane sleeve 2 through the air intake pipe 3 .

[0033] In this embodiment, the air inlet device may be a medical syringe.

[0034] Please refer to Figure 5 In this embodiment, the operation of the airbag membrane scale is as follows:

[0035] like Figure 5As shown in (a), when the device is not in use, the measuring section 23 and the supporting section 22 are both retracted in the tube body 1. Therefore, when in use, it is only necessary to implant the end of the airbag membrane sleeve ruler close to the latex membrane sleeve 2 into the endoscope clamp hole, and push it toward the target by holding the tube body 1 until it passes through the front end of the endoscope (observed from the endoscope) and reaches the measuring interval. The measuring interval here is the location of the lesion or trauma to be measured. Because the airbag membrane sleeve ruler in the utility model is based on endoscope use, when the airbag membrane sleeve ruler in the utility model is used, the front end of the endoscope has roughly reached the target interval to be measured. And the area is displayed on the endoscope display. Therefore, the operator can use the endoscope display to penetrate the airbag membrane sleeve ruler stone and extend it from the clamp hole at the front end of the endoscope. And during the measurement process, the measurement angle, unfolding state, stone approaching the detection area and other information of the airbag membrane sleeve ruler can be directly observed through the endoscope display.

[0036] When the airbag membrane scale reaches the measuring range as observed through the endoscope display, the measuring angle of the airbag membrane scale can be adjusted by rotating the tube body 1 to adjust it to the best measuring angle. Then the medical syringe can inject air into the tube body 1 through the air inlet 31, and observe the changes of the latex membrane sleeve 2 in the endoscope display while injecting air. When the support section 22 and the measuring section 23 in the latex membrane sleeve 2 in the endoscope display extend out of the tube body 1 and expand into a T-shaped solid scale under the action of the gas, stop inflating the tube body 1, as shown in FIG. Figure 5 (b) and Figure 5 (c), where Figure 5 (b) is the state of the latex membrane sleeve 2 just after being inflated, Figure 5 (c) is the state of the latex membrane sleeve 2 when it is fully filled. At this time, the measuring section 23 is able to measure the target size, and the measured data can be read by observing the endoscope display. Thus, the entire measurement operation is completed. The entire measuring device has a simple structure and the measurement process is simple and convenient to operate.

[0037] Please refer to Figure 5 In addition, before measurement, the measuring section 23 and the supporting section 22 are both retracted into the tube body 1, so during the measurement process, the measurement can be performed as long as the tube body 1 can reach the measuring section. In addition, since the measuring section 23 and the supporting section 22 are both made of ultra-thin latex, the space they occupy when unfolded is small and generally do not contact human tissue. And because it is made of ultra-thin latex material, the surface is relatively smooth, even if it contacts human tissue when unfolded, it will not cause damage to human tissue. Therefore, the airbag membrane sleeve ruler of the utility model can measure some areas with small lesions or traumas, thereby improving its practicality. In addition, since the measuring part thereof is made of ultra-thin latex, the surface is relatively smooth, resulting in no secondary damage to the human body during the unfolding process.

[0038] After the measurement is completed, the air in the tube body 1 can be extracted through a medical syringe on the end of the tube body 1 away from the latex membrane sleeve 2. At this time, the measuring section 23 and the supporting section 22 can be retracted into the tube body 1, so that the tube body 1 can be pulled out from the endoscope clamp hole and the entire airbag membrane sleeve scale will not come into contact with other things during the extraction process, thereby improving the safety of the entire measurement process.

[0039] In this embodiment, the latex membrane sleeve 2 is made of ultra-thin latex as a whole. The material of latex is relatively soft, so in the actual measurement process, the target at any position can be measured by adjusting the angle position of the endoscope and the airbag membrane sleeve scale.

[0040] Please refer to Figure 4 The measuring section 23 includes a measuring section 1 and a measuring section 2. The measuring section 1 and the measuring section 2 are arranged on both sides of the supporting section 22. The measuring section 1 and the measuring section 2 are extended out of the tube body 1 and are arranged perpendicular to the tube body 1 when the gas is introduced into the air inlet 1 31. Thus, the measuring section 23 can measure the size of the target. In this embodiment, by dividing the measuring section 23 into the measuring section 1 and the measuring section 2, and the measuring section 1 and the measuring section 2 are symmetrical structures relative to the supporting section 22 when unfolded, this symmetrical structure enables the gas to inflate the measuring section 1 and the measuring section 2 at the same time, keeping the measuring section 1 and the measuring section 2 in a unified state. In addition, the symmetrical structure only needs to adjust the position of the tube body 1 to the middle position of the area to be measured during the measurement operation, and then the measuring section 23 after the gas is injected can be unfolded and the measurement of the area to be measured can be achieved. It can be understood that the measurement section 1 and the measurement section 2 are symmetrical structures, so that when estimating the position of the tube body 1 during measurement, the movement of the tube body 1 can be limited to a certain extent, avoiding the situation where the measurement section 23 cannot fully measure the target size when the tube body 1 is moved arbitrarily. Therefore, the airbag membrane scale in this embodiment does not need to adjust the position of the tube body 1 during the measurement process, simplifying the measurement operation steps.

[0041] The support section 22 is provided with an air outlet 1, and the measuring section 23 is provided with an air inlet 2, the air inlet 2 is the same size as the air outlet 1, and the end surface where the air outlet 1 is located is connected to the end surface where the air inlet 2 is located by gluing. In this embodiment, the measuring section 23 and the support section 22 can be bonded by a medical adhesive.

[0042] In this embodiment, medical adhesive is also used to bond the mounting section 21 to the tube body 1. Medical adhesive is safe, reliable, non-toxic, sterile, has good bonding effect and good sealing after bonding, so it can effectively connect the support section 22 and the measuring section 23.

[0043] In this embodiment, the mounting section 21 and the supporting section 22 are an integrated structure, which is obtained by molding liquid latex by a dip molding method. The measuring section 23 is also obtained by molding liquid latex by a dip molding method.

[0044] In this embodiment, please refer to Figure 1 , the air inlet pipe 3 can be a medical Luer connector. The syringe can be connected to the tube body 1 through the medical Luer structure. The medical Luer connector is a universal connector that meets medical standards. It has good air tightness and anti-falling properties and meets national standards. Therefore, the air inlet pipe 3 adopts a medical Luer connector to ensure air tightness while preventing the syringe from easily falling off from the air inlet 31, thereby improving the stability of the entire injection or extraction process.

[0045] The diameter of the tube body 1 is smaller than the diameter of the endoscope's clamp channel hole, so that the airbag membrane scale in the utility model can extend into the front end of the endoscope through the endoscope's clamp channel hole and reach the measurement area.

[0046] The wall thickness of the latex membrane sleeve 2 is 0.02 mm to 0.06 mm. The thin wall thickness allows it to be completely retracted into the tube body 1 after being evacuated, and because the thin wall thickness allows it to not cause damage to human tissue even if it contacts human tissue when unfolded.

[0047] Preferably, the wall thickness of the latex film sleeve 2 is 0.04 mm.

[0048] The above describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
