Description

Technical Field

[0001] The utility model relates to the technical field of laser blood sampling, in particular to a laser blood sampling instrument protection device and a laser blood sampling instrument. Background Art

[0002] Laser blood collection devices are usually composed of a laser generator, a control circuit, a protective device, a display, an internal power supply and a charging adapter. Laser blood collection devices can be divided into many types according to different collection methods and functions, such as handheld laser blood collection devices, desktop laser blood collection devices, etc. Its working principle is to use a laser generator to emit a laser beam with a wavelength of 2.94um in an extremely short time, instantly generating high temperature and vaporizing a micropore in the skin tissue, thereby achieving the purpose of collecting blood samples.

[0003] When the laser is used to draw blood, the vaporization of the skin will produce mist and impurities, accompanied by bleeding. In order to prevent the mist and impurities from damaging the laser lens and prevent infection at the bleeding site, a replaceable protective device is generally set at the front end.

[0004] The protective device is generally arranged at the front end of the whole machine, coaxial with the laser beam emitted by the laser generator, and in direct contact with the skin. It has a main body of the laser channel, a light-transmitting filter membrane in the laser channel to prevent debris from entering, and a direct-insert fixing part and a stopper to prevent the protective device from detaching.

[0005] However, the above-mentioned protective devices have the following disadvantages:

[0006] First, when the laser is output, it will pass through the light-transmitting filter, which will cause energy attenuation and place higher requirements on the laser output;

[0007] Second, the laser will produce vaporized mist and impurities when puncturing and sampling blood. Although the light-transmitting filter prevents damage to the laser lens, it cannot prevent the mist and impurities from contaminating the bleeding site and causing thermal damage to the human body, which increases the psychological burden on the user.

[0008] Third, the installation structure is not compact, which may cause it to loosen and fall off or be difficult to disassemble, and it may get stuck at the front end of the laser generator. Utility Model Content

[0009] In order to solve the above technical problems, the purpose of the utility model is to provide a conveniently detachable protective device for a laser blood collection instrument to avoid energy attenuation and thermal damage.

[0010] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: a laser blood collection instrument protective device, comprising an internally hollow shell and a shielding adsorbent, wherein one end of the shell is open and detachably connected to an external laser generator, and a laser through hole is provided in the middle of the other end, and the shielding adsorbent is coaxially assembled inside the shell, and an impurity exclusion zone is defined inside the shell between the laser through hole and the shielding adsorbent, and the impurity exclusion zone is connected to the outside, and a laser channel for the laser to pass through is provided in the middle of the shielding adsorbent.

[0011] The beneficial effect of the utility model is that when the device is mounted on the laser generator of a laser blood collection instrument, blood mist and impurities generated when the laser touches the skin enter the device through the laser through hole and are discharged to the outside of the device in the impurity removal area, so that the device can achieve real-time impurity removal without installing a filter lens, avoiding energy attenuation while protecting the lens of the laser generator.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the shell includes a sleeve and a sleeve, the sleeve is coaxially assembled inside the sleeve, and an annular gap connected to the outside is formed between the two. The laser through hole is arranged in the middle of one end of the sleeve, and the shielding adsorption component is assembled inside the sleeve. The end of the sleeve close to the laser through hole has a plurality of air holes connected to the annular gap distributed along its circumferential direction.

[0014] The above technical solution sets a sleeve and a sleeve, and sets an air hole on the outside of the sleeve, so that the blood mist and impurities generated during laser blood sampling are discharged outside the device through the air hole before reaching the shielding adsorption component, thereby achieving the purpose of preliminary impurity removal.

[0015] Furthermore, the shielding adsorbent includes a blocking member and an adsorbent, which are assembled inside one end of the sleeve and are spaced apart in sequence along its axial direction to form a buffer zone therebetween. A second laser through hole is opened in the middle of the blocking member, and a third laser through hole is opened in the middle of the adsorbent. A plurality of air ducts connected to the annular gap are arranged in an annular direction along the third laser through hole inside the adsorbent, and ports of the air ducts extend to the lower surface of the adsorbent.

[0016] In the above technical solution, after the blood mist and impurities generated by laser blood sampling are initially removed, a portion of the blood mist and impurities enter the buffer zone through the second laser through hole of the blocking member and are discharged to the outside of the device through the air duct of the adsorption member.

[0017] Furthermore, the blocking member is a funnel-shaped member.

[0018] The above technical solution sets the baffle as a funnel-shaped component so that most of the external impurities can fall outside the baffle, thereby reducing the possibility of impurities or blood mist reaching the laser generator lens and improving the protection capability of the lens.

[0019] Furthermore, the lower surface of the adsorption component is set to be conical, or the upper surface and the lower surface of the adsorption component are both set to be conical.

[0020] The above technical solution provides a funnel-shaped or hourglass-shaped adsorbent. By setting the adsorbent to be funnel-shaped and cooperating with a funnel-shaped baffle, the volume of the buffer zone between the two is expanded to extend the floating distance of impurities and further avoid the possibility of impurities reaching the lens.

[0021] Furthermore, a thread groove is provided on the inner wall of one end of the sleeve away from the laser through hole, and is compatible with an external laser blood sampling instrument.

[0022] In the above technical solution, when the device needs to be disassembled, the sleeve is rotated to drive the sleeve to be rotated out, thereby improving the convenience of disassembly and assembly of the device.

[0023] Furthermore, an anti-slip structure is provided on the outside of the sleeve.

[0024] The above technical solution provides an anti-skid structure on the outside of the sleeve, which makes it easier for the user to hold the sleeve and rotate it, thereby preventing the fingers from slipping.

[0025] Furthermore, the anti-slip structure includes a plurality of strip grooves extending along the length direction of the sleeve, and the plurality of strip grooves are distributed on the sleeve at annular intervals.

[0026] The above technical solution provides strip grooves spaced apart in the circumferential direction on the outside of the sleeve, thereby improving friction when the device is hand-held and rotated, thereby preventing the user's fingers from slipping.

[0027] The second purpose of the utility model is to provide a laser blood sampling instrument which can remove impurities in real time without installing a light-transmitting filter membrane.

[0028] In order to achieve the above-mentioned purpose, the technical solution of the utility model is as follows: it includes a laser blood collection instrument protection device.

[0029] The above technical solution protects the lens of the laser generator by assembling the laser blood collection instrument protection device on the laser generator of the laser blood collection instrument, while avoiding the safety hazard of heat damage to the user caused by blood mist and impurities.

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] Example

[0037] like Figure 1-3 As shown, a protective device for a laser blood collection instrument includes a shell 1 with a hollow interior and a shielding adsorbent. One end of the shell 1 is open and detachably connected to an external laser generator, and a laser through hole is provided in the middle of the other end. The shielding adsorbent is coaxially assembled inside the shell 1. An impurity exclusion zone is defined inside the shell 1 between the laser through hole and the shielding adsorbent, and the impurity exclusion zone is connected to the outside. A laser channel for the laser to pass through is provided in the middle of the shielding adsorbent.

[0038] The working principle is: when the device is used to perform laser blood sampling on the user, the blood mist and impurities generated during blood sampling enter the device shell through the laser through-hole. When passing through the impurity removal area and the shielding adsorption part, the blood mist and impurities are automatically discharged to the outside of the device because the impurity removal area is connected to the outside, thereby avoiding the energy attenuation caused by the installation of the filter lens, protecting the lens of the laser generator, and avoiding thermal damage to the user's skin caused by the blood mist and impurities.

[0039] When the device is mounted on the laser generator of a laser blood collection instrument, the blood mist and impurities generated when the laser touches the skin enter the device through the laser through-hole and are discharged from the device in the impurity removal area. This allows the device to achieve real-time impurity removal without installing a filter lens, avoiding energy attenuation while protecting the lens of the laser generator.

[0040] Preferably, the shell 1 includes a sleeve and a sleeve 2, the sleeve 2 is coaxially assembled inside the sleeve, and an annular gap 11 connected to the outside is formed between the two. The laser through hole is arranged in the middle of one end of the sleeve, and the shielding adsorption component is assembled inside the sleeve 2. The end of the sleeve 2 close to the laser through hole is provided with a plurality of air holes 5 connected to the annular gap at intervals along its circumference.

[0041] The annular gap is connected to an external exhaust fan, so that the external exhaust fan can drive the air flow to move, thereby quickly discharging impurities from the inside of the device.

[0042] The working principle is: when the blood mist and impurities reach the air hole 5, the impurities are driven by the external airflow through the air hole 5 to the external annular gap 11, and finally discharged to the outside of the device through the opening at one end of the annular gap between the sleeve 2 and the sleeve, so that the device can pre-exclude part of the blood mist and impurities.

[0043] The above technical solution sets a sleeve 2 and a sleeve, and sets an air hole outside the sleeve 2, so that the blood mist and impurities generated during laser blood sampling are discharged outside the device through the air hole 5 before reaching the shielding adsorption component, thereby achieving the purpose of preliminary impurity removal.

[0044] Preferably, the shielding adsorbent includes a baffle 4 and an adsorbent 3, which are assembled inside one end of the sleeve 2 and are spaced apart in sequence along its axial direction to form a buffer zone therebetween. A second laser through hole is opened in the middle of the baffle 4, and a third laser through hole is opened in the middle of the adsorbent 3. A plurality of air ducts 8 connected to the annular gap are arranged in an annular direction along the third laser through hole inside the adsorbent 3, and the ports of the air ducts 8 extend to the lower surface of the adsorbent 3.

[0045] The working principle is: after a part of the blood mist and impurities are discharged through the air hole 5, the remaining impurities reach the buffer zone through the second laser through hole. At this time, under the influence of the air flow, the remaining impurities pass through the air duct 8 and are discharged outside the device.

[0046] In the above technical solution, after the blood mist and impurities generated by laser blood sampling are initially removed, a portion of the blood mist and impurities enter the buffer zone through the second laser through hole of the blocking member 4 and are discharged to the outside of the device through the air duct 8 of the adsorption member 3.

[0047] Preferably, the blocking member 4 is a funnel-shaped member.

[0048] The working principle is as follows: the blocking member 4 can be set as a funnel-shaped component to improve the structural strength of the blocking member 4, and at the same time, most of the impurities are blocked outside the blocking member 4 to improve the protection capability of the lens.

[0049] The above technical solution sets the baffle 4 as a funnel-shaped component so that most of the external impurities can fall outside the baffle 4, thereby reducing the possibility of impurities or blood mist reaching the laser generator lens and improving the protection capability of the lens.

[0050] Preferably, the lower surface of the adsorption member 3 is configured to be conical, or both the upper surface and the lower surface of the adsorption member 3 are configured to be conical.

[0051] Among them, Figure 1The third laser through hole is arranged on a side of the adsorption member 3 away from the second laser through hole.

[0052] The working principle is: by setting the adsorption component 3 to be a funnel-shaped or hourglass-shaped component, the adsorption component 3 cooperates with the baffle 4 which is also funnel-shaped, thereby extending the length of the buffer zone between the two, thereby achieving the purpose of buffering impurities and blood mist, and at the same time, the internal air duct 8 of the adsorption component 3 can further remove impurities.

[0053] The above technical solution expands the volume of the buffer zone between the two by setting a funnel-shaped or hourglass-shaped adsorbent 3, and cooperating with a funnel-shaped baffle 4, thereby extending the floating distance of impurities and further avoiding the possibility of impurities reaching the lens.

[0054] Preferably, a thread groove is formed on the inner wall of one end of the sleeve 2 away from the laser through hole, and is compatible with an external laser blood sampling instrument.

[0055] The working principle is: by opening a thread groove inside the sleeve 2, the sleeve 2 is screwed onto the outside of the laser generator, thereby improving the convenience of disassembly and assembly of the device.

[0056] The above technical solution improves the convenience of disassembly and assembly of the device by rotating the sleeve to drive the sleeve 2 to rotate out when the device needs to be disassembled and assembled.

[0057] Preferably, an anti-slip structure is provided on the outside of the sleeve.

[0058] The working principle is: an anti-skid structure is arranged on the outside of the sleeve to help improve the anti-skid performance between the user's fingers and the sleeve when the user holds the device and rotates it.

[0059] The above technical solution provides an anti-skid structure on the outside of the sleeve, which makes it easier for the user to hold the sleeve and rotate it, thereby preventing the fingers from slipping.

[0060] Preferably, the anti-slip structure includes a plurality of strip grooves 6 extending along the length direction of the sleeve, and the plurality of strip grooves 6 are distributed on the sleeve in an annular manner.

[0061] The working principle is: when the device needs to be disassembled, the strip groove 6 arranged on the outside of the sleeve can effectively increase the friction between the user's hand and the sleeve, thereby improving the convenience of disassembly and assembly of the device.

[0062] The above technical solution provides strip grooves 6 spaced apart along the circumferential direction on the outside of the sleeve, thereby increasing friction when the device is hand-held and rotated, thereby preventing the user's fingers from slipping.

[0063] The second purpose of the utility model is to provide a laser blood sampling instrument which can remove impurities in real time without installing a light-transmitting filter membrane.

[0064] Preferably, a laser blood collection instrument protection device is included.

[0065] The working principle is: by setting the protective device of the laser blood collection instrument outside the laser generator of the blood collection instrument, the blood collection instrument can be free of light-transmitting filter membrane at the laser generator end and can perform real-time impurity removal.

[0066] The above technical solution protects the lens of the laser generator by assembling the laser blood collection instrument protection device on the laser generator of the laser blood collection instrument, while avoiding the safety hazard of heat damage to the user caused by blood mist and impurities.
